Pioneering Evolution LLC

Own architecture and implementation of complex platform components, mentor junior engineers, and establish scalable engineering patterns. | 7+ years professional development with advanced C#/.NET, enterprise backend, relational DB, Angular frontend, and U.S. citizenship. | Own the hard parts. Every platform has a few problems that everyone quietly hopes someone else will pick up. The saga that half-completes. The tenant boundary that leaks under one specific permission configuration. The schema version that three modules depend on and nobody wants to touch. We are looking for the engineer who picks those up. Pioneering Evolution has spent over 15 years building the software that federal acquisition and financial management actually runs on. Our name is not decorative — we exist to push boundaries, explore new possibilities, and catalyze change in a domain that does not hand out change easily. Our Pioneers are at the forefront of something new, taking risks and venturing into uncharted territory. We are building a federated enterprise platform for complex federal mission environments, and we need senior engineers who can own complex components. The architecture, honestly: At Pioneering Evolution, we are building a Mission Operating System (Mission OS) called SyncCore™, designed to connect data, systems, workflows, and decisions across complex mission environments. SyncCore provides the secure, event-driven digital backbone for identity, integration, canonical data, governance, auditability, and interoperability—creating a trusted foundation on which mission capabilities can rapidly evolve. It is the foundation everything else stands on. Built on SyncCore, SyncPoint™ is a modular application ecosystem composed of independently deployable modules that address specific operational needs, including requirements management, budgeting, task planning, resource allocation, execution, and decision support. Real programs. Real money. Real decisions. We are not looking for a Senior Software Engineer simply to take the hardest tickets in the backlog. We are looking for an engineer who wants to help build the architecture, engineering culture, and technical foundation of a platform we expect to evolve for years. You will take ownership of significant capabilities across SyncCore or SyncPoint—from architecture and domain modeling through APIs, event-driven workflows, data persistence, user experience, testing, deployment, and production performance. You will decide how services communicate, where boundaries belong, how data moves through the system, and how we build software that stays secure, observable, maintainable, and extensible as the platform grows. You will also help raise the engineering capability of the people around you. That means thoughtful code reviews, mentoring junior and mid-level engineers, challenging architectural assumptions, establishing patterns where they are useful, and knowing when not to introduce complexity just because the technology makes it possible. You may work on the SyncCore platform itself—identity, integration, eventing, canonical data, shared services, governance, auditability, and platform APIs—or lead the engineering of a SyncPoint mission module that turns complicated operational processes into intuitive software. Either way, you will be close to the problem, close to the architecture, and close to the people making the decisions. No layers of bureaucracy separate you from the impact of what you build. Current stack: C#, .NET 8+, ASP.NET Core, MediatR-based CQRS-lite command pipeline, PostgreSQL with Entity Framework Core, Cosmos DB for saga audit, RabbitMQ with Wolverine for messaging, Hangfire for scheduled work, YARP for gateway routing, Angular 19 and TypeScript, Docker, Bitbucket Pipelines, xUnit, and Azure / Azure Government with CUI and IL4 controls throughout. The architecture is modern, but the technology isn’t the point. The point is using it to solve difficult problems exceptionally well. SyncCore and SyncPoint are being built now—not inherited from another team and not already set in stone. If you want your fingerprints on a new platform's architecture rather than simply maintaining someone else’s, this is that opportunity. We currently use a micro-frontend architecture. If you have done it, we want to hear about it. What we actually require: * Typically 7+ years of professional software development experience. * Advanced C# and modern .NET / ASP.NET Core. * Strong enterprise backend and REST API development at scale. * Deep relational data and ORM experience, including design and performance work. * Angular or comparable modern enterprise frontend experience. * Experience with asynchronous messaging and event-driven systems — sagas, eventual consistency, idempotency, the failure modes that only show up in production. * Experience with distributed or microservice-based applications. * Strong automated testing and diagnostic instincts. * The ability to independently own complex features or entire application components. * Real experience conducting technical code reviews and mentoring other engineers. This is not a bonus line item. It is a substantial part of the job. Strong alignment with our current .NET / Entity Framework / PostgreSQL / Angular / RabbitMQ stack is genuinely valued at this level — at senior, the specifics do start to matter more. How the leadership actually works here, so there is no surprise on day one: system architecture and engineering standards are owned by the Chief Engineer. The Tech Lead owns day-to-day technical execution, decomposition, and team coordination. Senior Software Engineers lead through hands-on implementation, feature design, troubleshooting, code review, and mentorship. This is a hands-on-keyboard senior role, not a title on the way out of the IDE. That requires a small team with high standards, strong engineering judgment, and very little tolerance for “good enough.” Who thrives here: We move fast, and we are trying to create something genuinely special — a platform architecture that outlasts the contract that funded it. That is not a thing a slow company or a mediocre team gets to do. Ours is a small, dynamic team of people who are excellent at this work and who want to be surrounded by others who are. If you have spent a few years as the only engineer on a team who cared about the hard parts, you will find better company here. You will be building alongside talent worth building alongside, and your standards will raise the team’s rather than being sanded down by it. Clearance, citizenship, and location: * U.S. citizenship is required. No exceptions. * An active clearance is not required to apply. Active Secret is welcome. Otherwise, interim Secret eligibility is required and PE sponsors — we will walk you through it. * Hybrid, a few days a week at our Arlington HQ, 2550 S. Clark Street. What we offer: $132,000 – $165,000 based on demonstrated depth, scope of prior ownership, and interview performance. Plus paid time off, 10 paid holidays, medical, dental, and vision, company-paid life and AD&D, company-paid short- and long-term disability, 401(k) with company contribution, legal assistance, tuition reimbursement, and continuing education opportunities. The honest pitch for a senior engineer: we are a small, fast-growing team building something architecturally ambitious for a customer whose mission actually matters. There is no committee between you and a design decision. There is no legacy monolith you are forbidden to touch. There is a real platform, a real roadmap, and a team that will be measurably better because you joined it. We are willing to challenge the status quo, embrace unconventional approaches, and blaze a trail for others to follow. Bring a compass. Innovate. Accelerate. Evolve. Pioneering Evolution is an equal opportunity employer.

Develop and own platform modules including APIs and event-driven workflows working with senior engineers. | 3+ years professional experience in C# and .NET with U.S. citizenship and Secret clearance eligibility. | You have shipped real software. We have real software to ship. You are past the stage where every requirement needs to arrive perfectly defined. You can take a feature from a half-formed conversation to something in production that does not page anyone at 2 a.m. You have opinions about ORMs, and you can explain why. Good. Let’s talk. Pioneering Evolution has spent over 15 years automating acquisition and financial management for federal programs — the budgeting, tasking, and execution machinery that moves billions of dollars through the Navy. Our applications have won awards, and more importantly, they have won over the people who have to use them every day. We call our people Pioneers. We challenge the status quo, embrace unconventional approaches, and blaze a trail for others to follow. Then we document it, because someone has to maintain it. The systems: At Pioneering Evolution, we are building a Mission Operating System (Mission OS) called SyncCore™, designed to connect data, systems, workflows, and decisions across complex mission environments. SyncCore provides the secure, event-driven digital backbone for identity, integration, canonical data, governance, auditability, and interoperability—creating a trusted foundation on which mission capabilities can rapidly evolve. It is the foundation everything else stands on. Built on SyncCore, SyncPoint™ is a modular application ecosystem composed of independently deployable modules that address specific operational needs, including requirements management, budgeting, task planning, resource allocation, execution, and decision support. Real programs. Real money. Real decisions. This is genuine distributed-systems work with a federated architecture, event-driven integration, and real multi-tenancy — not a CRUD app wearing a microservices costume. This is not a role where you will spend your first year fixing tickets in somebody else’s ten-year-old application. As a Mid-Level Software Engineer, you will own meaningful pieces of the platform or a SyncPoint module from design through production. You might build an API one sprint, design an event-driven workflow the next, work through a difficult data-modeling problem with an architect, or take a feature from an Angular interface all the way through the application and data layers. You will work alongside senior engineers and architects, but we expect you to bring ideas to the table, challenge assumptions, make engineering decisions, and increasingly own the technical outcome—not simply implement someone else’s design. You would join either the SyncCore platform team or one of our SyncPoint module teams. On the platform side, you may work on capabilities such as identity, integration, eventing, shared services, data architecture, auditability, and platform APIs. On a module team, you will translate complex real-world mission and business problems into software people actually depend on to do their jobs. The stack: C#, .NET 8+, ASP.NET Core, a CQRS-lite command pipeline, PostgreSQL with Entity Framework Core, RabbitMQ for asynchronous and event-driven flows, Angular 19 and TypeScript, Docker, CI/CD, Azure Government, xUnit, and micro-frontends. What we actually require: * Typically 3+ years of professional software development experience. * Strong professional experience with C# and modern .NET / ASP.NET Core. * The ability to independently build REST APIs, backend services, and real business logic — not just wire up someone else’s design. * Entity Framework Core or a comparable ORM, and the judgment to know when to drop to SQL instead. * Strong relational database fundamentals. You can read a query plan without flinching. * Experience writing automated unit and integration tests, as a habit rather than a chore. * Working experience with JavaScript or TypeScript and modern web applications. * The ability to deliver a complete, production-ready feature end to end. Worth saying plainly: backend .NET depth matters more to us than an exact full-stack match. If you are strong on the server and competent-but-not-expert on the front end, you are still a strong candidate. We would rather have real backend depth than a résumé that lists ten frameworks at equal shallowness. Strongly preferred, not required: PostgreSQL, Angular, RabbitMQ, Docker, Azure, distributed systems, microservices, event-driven patterns. A note for the Java engineers reading this: If you already write strongly typed, object-oriented software professionally and everything else above describes you, apply. C# is learnable. Engineering judgment is much harder to teach. We are more interested in how you design and build software than which package manager you used at your last job. Who thrives here: We move fast, and we are trying to create something special rather than something that merely satisfies a requirements document. That takes a dynamic team, and ours is small enough that everyone’s work is visible and stacked with people who are genuinely talented at this. The engineers who do best here want that. They want to build next to people who are better than them at something, to have their design questioned by someone who has earned the right to question it, and to be part of a team where the standard is set by the work rather than by a process. If you have spent time somewhere that your best work disappeared into a backlog, this will feel different. Clearance, citizenship, and location: * U.S. citizenship is required. No exceptions. Federal program requirement, not negotiable. * An active clearance is not required to apply. Active Secret is welcome. Otherwise you need to be eligible for an interim Secret, and PE sponsors — we handle the paperwork and walk you through the process. * Hybrid, a few days a week at our Arlington HQ, 2550 S. Clark Street. What we offer: $112,000 – $132,000 based on demonstrated depth, scope of prior responsibility, and interview performance. Plus paid time off, 10 paid holidays, medical, dental, and vision, company-paid life and AD&D, company-paid short- and long-term disability, 401(k) with company contribution, legal assistance, tuition reimbursement, and continuing education opportunities. You will work directly with our Lead Architect, Chief Engineer, and Tech Lead — a short chain between a good idea and it being in the codebase. Small team, real ownership, architecture decisions you can actually influence. If you have been waiting to be senior enough for your opinion to count, that wait ends here. Innovate. Accelerate. Evolve. Pioneering Evolution is an equal opportunity employer.
