Primer's power grows every time a new partner plugs in — and we make that possible at scale!
In the Partners team we build the platform that enables third parties to unlock Primer's unified payments infrastructure and use
it as a foundation for their own growth. We're building the app store for payments: a scalable, flexible ecosystem where partners
can discover, integrate, and distribute through Primer.
This team covers: Partner Dashboard, Partner Integration Ownership & Management, Marketplace, Documentation & Samples, Payment &
Workflow Integrations, and the underlying integration framework (Nexus) that powers everything under the hood.
Partners is made up of two sub-teams: Partner Experience, focused on the tools and interfaces that make Primer an attractive and
easy platform for third parties to build on; and Integrations Core, focused on the technical frameworks that make integrations
scalable, consistent, and maintainable.

onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face

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. BENEFITS & PERKS * A choice between medical plans with an option for 100% covered premiums * Fertility and adoption benefits * Access to supplemental insurance plans for additional coverage * Headspace mindfulness app subscription * Global Employee Assistance Program * Retirement benefits with employer match * Flexible paid time off * 12 weeks paid parental leave and family care leave * Pretax commuter benefit * Education reimbursement * Employee donation match to community organizations * 7 Global Employee Resource Groups (ERGs) * Dog-friendly workplace * Free lunch and snacks * Private rooftop * Hack week twice per year CASH COMPENSATION RANGE: $185,500 - $299,000 USD The base salary for this position will vary based on job-related criteria including relevant skills, experience, and location, among other factors.
