Own and automate traffic infrastructure across edge routing, private connectivity, service mesh, DNS, TLS, and observability. | Requires 7+ years of software engineering experience, deep Istio and Envoy expertise, Kubernetes networking, CDN operations, cloud networking, and strong networking fundamentals. | 🚀 Join the Future of Commerce with Whatnot! Whatnot is the largest live shopping platform in North America and Europe to buy, sell, and discover the things you love.

Check out the latest Whatnot updates on our news and engineering blogs and join us as we enable anyone to turn their passion into a business and bring people together through commerce. 💻 Role We're looking for an Infrastructure Engineer to own the path between Whatnot's customers and our code. The Traffic team owns every hop along that path: the edge, DNS, private connectivity, the service mesh, TLS, and internal access. We make it fast, reliable, and secure by default, so product engineers ship globally without thinking about the network. You'll partner closely with Reliability and Platform Engineering to get observability right. Network problems are only debuggable if the data already exists when the incident starts, so you'll work with those teams to instrument every layer of a request, land those signals in the tooling engineers already use, and make "is it the network?" a question answered with evidence in minutes instead of debated for hours. You'll work with Security just as closely on how traffic enters, leaves, and moves inside our perimeter. This is a hands-on, software-first role rather than a network administration one. You'll write controllers, extensions, and automation, and the bar for success is that other engineers stop needing to think about the layer you own. Our surface area covers the full journey of a request, and you will work across most of it: • Shape how traffic reaches us at the edge, from caching and security posture to the routing decisions that determine how fast Whatnot feels in each part of the world • Build and scale the private connectivity that carries traffic between our services, accounts, and clusters, and keep it secure as the topology grows • Push our service proxy and mesh layer further, tuning it for the traffic patterns we actually have and extending it when the off-the-shelf configuration stops being enough • Keep name resolution, TLS, and internal access boring, and automated, to the engineers who depend on them • Make the network legible. Every layer of a request should be instrumented well enough that "is it the network?" gets answered with evidence in minutes instead of debated for hours • Design for the failure cases first. Network changes carry enormous blast radius, so you will build tooling that makes correct changes easy and dangerous ones hard, and rehearse failover before we need it We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection.

They care more about outcomes than credit and stay close to the product and the people using it. • Bachelor’s degree in Computer Science, a related field, or equivalent practical experience. • 7+ years of professional software engineering experience preferably running the network behind high-traffic applications. • Have deep, hands-on experience (3+ years) with Istio and Envoy. You know the components and configuration surface intimately and have tuned them successfully for very different use cases • Have written custom Envoy extensions when configuration alone wasn't enough • Know Kubernetes networking deeply, from CNI behavior and pod and service networking to ingress and how traffic actually moves inside and between clusters • Have operated a CDN at scale, preferably Cloudflare • Have run globally distributed applications and understand what differs when your users and your infrastructure sit in different regions • Have owned latency-sensitive systems and can reason precisely about where milliseconds come from and go • Have strong networking fundamentals across DNS, TLS, TCP, and routing, plus genuine curiosity about the layers beneath the application • Know modern cloud provider networking deeply, AWS in particular. You have designed VPC topology at scale and understand the tradeoffs between Transit Gateway, PrivateLink, peering, and NAT well enough to pick the right one and defend it • Debug across boundaries. You are comfortable with packet captures, proxy logs, and traces, and you answer "is it the network?" with data 🎁 Benefits • Generous Holiday and Time off Policy • Health Insurance options including Medical, Dental, Vision • Work From Home Support • Home office setup allowance • Monthly allowance for cell phone and internet • Care benefits • Monthly allowance for wellness • Annual allowance towards Childcare • Lifetime benefit for family planning, such as adoption or fertility expenses • Retirement; 401k offering for Traditional and Roth accounts in the US (employer match up to 4% of base salary) and Pension plans internationally • Monthly allowance to dogfood the app • All Whatnauts are expected to develop a deep understanding of our product.

It directly shapes buyer trust, seller confidence, CX burden, trust and enforcement decisions, and shipping economics. The Logistics Platform team builds the shared systems, data, and capabilities beneath shipping on Whatnot. That includes core logistics data, tracking and scan normalization, platform interfaces, and the observability and investigation surfaces that other teams rely on. We’re looking for a Senior Software Engineer, Logistics Platform to help make those systems more trustworthy, operable, and easy to build on. This is a product-minded platform role: much of the work is internal-facing, but the impact is very external — better buyer and seller experience, fewer support issues, stronger trust decisions, and better margin outcomes. As a Software Engineer On Logistics Platform, You Will • Build and improve source-of-truth systems, APIs, and internal platform interfaces that other teams depend on for logistics workflows and decisions. • Own backend and platform work across logistics data quality, shipment state normalization, observability, and operational debugging surfaces. • Partner closely with Product, Data Science, CX, Ops, Trust, and Finance to turn messy real-world logistics problems into durable systems and better user outcomes. • Improve the correctness, timeliness, and usability of the logistics data that powers support, trust, product, and operational workflows. • Build tooling, monitoring, and debugging primitives that help teams detect problems earlier and get to truth faster. • Use AI thoughtfully in day-to-day engineering work to improve quality, learning speed, debugging, and execution — while keeping a strong independent bar for correctness and risk judgment.

Nice To Have • Experience in adjacent domains like rideshare coordination, food delivery, marketplace fulfillment, trust/risk operations, or order tracking and exception-handling systems. • Experience working on a marketplace or other two-sided platform. • Direct experience in logistics, shipping, or fulfillment systems. 🎁 Benefits • Flexible Time off Policy and Company-wide Holidays (including a spring and winter break) • Health Insurance options including Medical, Dental, Vision • Work From Home Support • Home office setup allowance • Monthly allowance for cell phone and internet • Care benefits • Monthly allowance for wellness • Annual allowance towards Childcare • Lifetime benefit for family planning, such as adoption or fertility expenses • Retirement; 401k offering for Traditional and Roth accounts in the US (employer match up to 4% of base salary) and Pension plans internationally • Monthly allowance to dogfood the app • All Whatnauts are expected to develop a deep understanding of our product.

Run the invoice reconciliation process across all carriers and integrators, ensure carrier charges map correctly to internal data, drive rate shadowing to catch mispricing, and partner with Accounting, Strategic Finance, and Analytics to reconcile margin reporting into a single trusted source of truth. Manage carrier relationships and negotiations. Own the weekly/biweekly operating cadence with each carrier and integrator, set agendas that drive our priorities, escalate and resolve operational issues (rate card mismatches, incorrect surcharges, RTS spikes, collections delays), and lead or support rate negotiations, RFPs, and contract changes. Recover money we're owed. Own claims at scale (thousands of loss/damage claims per week), bulk claims programs, unused label refunds, and overcharge credits — a direct, measurable margin lever. Own carrier-side seller and CX operations. Oversee high-value stuck-shipment resolution, BYOL support, seller collections, hazmat violation management, and carrier violation remediation in partnership with Account Managers and Support. Launch and scale. Onboard new carriers, service levels, lanes, and markets — from commercial diligence through data integration and ramp — and set the 12-18 month strategy for the carrier function as Whatnot's volume and international footprint grow. Build and lead the team. Manage and develop a team of carrier operations analysts and associates, define clear ownership across monitoring, pricing, reconciliation, and escalations, and identify what to automate, playbook, or hand off as we scale. 👋 You Curious about who thrives at Whatnot?
