Software engineer jobs in Seattle, WA

About the role

We're hiring a Full Stack Engineer to help us build and evolve the product layer of Integrate's platform. This role spans the full stack — from React-based UI surfaces to Go APIs and the integrations that tie them together — and sits at the center of where our product meets our users. The near-term focus includes feature work on our cross domain solution workflows, improving how we surface complex project data to end users, and contributing to the API and integration services that sit beneath it. You'll work closely with product, design, and backend engineers to ship things that matter — and you'll be expected to care about the quality and craft of what you build. A meaningful part of this role is operating with a Top Secret clearance. Integrate's platform is built to run across classification levels — including NIPR, SIPRnet, SAP networks, to JWICS — and the programs we support don't always surface their full complexity in unclassified environments. Having clearance means being in the room when the full picture is visible: understanding the mission constraints, threat variables, and program complexities that drive real requirements but rarely make it into a ticket. For an engineer building coordination software for defense programs, that context isn't a nice-to-have — it's the difference between shipping features and shipping the right features. We're a small team. There's no handoff culture here. If you build it, you own it. This role requires an active TS or TS/SCI clearance. We move fast and need people who can hit the ground running — cleared candidates ready to start are at the top of our list. If you're lapsed, tell us where you left off and we'll talk.

What you'll bring

• We don't expect you to be an expert in all of these things — but here's the kind of background that sets you up to succeed:
• 3–5+ years of full stack engineering experience in a product-focused environment
• Strong React fundamentals — component architecture, state management, and performance
• Solid HTML5 and CSS3
• able to build clean, responsive interfaces without leaning on a framework crutch
• Go on the backend — REST API development, middleware, and service patterns
• PostgreSQL — comfortable with schema design, query writing, and migrations
• GraphQL — can read and reason about a resolver, understands n+1 patterns and common pitfalls
• Familiarity with integration patterns — webhooks, third-party API design, or similar
• Some exposure to broader backend concerns: caching, rate limiting, or async processing
• GitHub Actions or similar CI/CD tooling
• You're comfortable across the stack — whether that's a component tree or an API route handler.
