Lead technical direction and architecture of a high-scale communications platform, providing hands-on leadership and mentorship while balancing delivery and platform health. | 10+ years backend engineering with deep Java and distributed systems expertise, staff-level technical leadership, messaging systems, and cloud infrastructure experience. | Squarespace is looking for a Backend Staff Software Engineer to lead the technical direction of our Communications Platform team. The Communications Platform is a critical engine powering customer engagement across Squarespace — providing internal teams with a scalable, reliable, and secure infrastructure for delivering communications via email, push notifications and in-product messaging. The team owns multiple interconnected production platforms that collectively send over 1.75+ million notifications per day, strategic initiatives including platform modernization, In-Product Placements, and multi-channel communication capabilities. In this role, you’ll serve as the senior technical voice for the team — driving architecture, shaping roadmap execution, and elevating the engineering quality of a small but high-impact team. This is a hands-on role with real technical depth, paired with broad cross-functional influence. This is a hybrid role based in our NYC office (3 days per week), reporting to the Engineering Manager of Communications Platform. You’ll Get To… Drive the architecture, design, and implementation of the Communications Platform’s platforms — including Email Delivery, In-Product Notifications and Push Notifications. Define and own the technical strategy for platform modernization, reliability hardening, and engineering standards across backend services. Provide hands-on technical leadership and mentorship to a team of backend and frontend engineers, helping them grow in system design, decision-making, and ownership. Write high-quality Java code and stay close to execution — leading design reviews, code reviews, and architectural decisions that raise the bar across the codebase. Proactively identify and address systemic risks in performance, reliability, security, and operability before they become incidents. Serve as a key technical partner on cross-team and company-wide architecture initiatives. Balance short-term delivery with long-term platform health, communicating tradeoffs clearly to stakeholders and leadership. Who We’re Looking For 10+ years of backend engineering experience, with significant time building and operating large-scale, customer-facing systems. Deep expertise in Java and backend service development, including APIs, async processing, messaging systems (ex: Kafka), and data stores (ex: MongoDB, CockroachDB). Strong experience with distributed systems in production — including reliability, scaling, failure modes, and observability. A proven track record of technical leadership at the Staff or Senior-plus level, influencing architecture across multiple teams or services. Experience evolving existing systems — modernizing legacy platforms, simplifying complexity, and strengthening reliability without unnecessary rewrites. Experience operating within platform engineering contexts, where your customers are internal or external product teams and the quality of your APIs and abstractions directly shapes their velocity. A strong understanding of multi-channel communication infrastructure (email delivery, push, in-product notifications) is a meaningful plus. The ability to communicate complex technical concepts clearly to both technical and non-technical partners. A mindset oriented toward mentorship, collaboration, and inclusive technical leadership. Technologies You'll Work With Java, Spring, Kafka, MongoDB, CockroachDB, Kubernetes, GCP. The team actively uses Claude Code, Cursor and GitHub Copilot to accelerate development and code review.
