Full Stack Software Engineer

Integrate•Seattle, WA

8d•$110,000 - $155,000

About The Position

Integrate is hiring a Full Stack Software Engineer to build and evolve the product layer of its platform. The role spans React-based user interfaces, Go APIs, and the integrations connecting them, with a focus on the product experience and how users interact with complex program data. Near-term work includes developing cross-domain solution workflows, improving how complex project data is presented to users, and contributing to the API and integration services beneath those experiences. The engineer will work closely with product, design, and backend engineers and participate in product decisions by understanding user problems, raising concerns when solutions do not serve users well, and treating UX quality and polish as engineering requirements. The team expects engineers to own what they build from end to end. Integrate is based in Seattle and builds a real-time, cross-boundary project management platform for complex programs across government and commercial environments. This position requires access to export-controlled information, so US person status is required. US persons include US citizens, U.S. permanent residents, individuals granted U.S. asylum status, and individuals admitted in U.S. refugee status.

Requirements

3–5+ years of full stack engineering experience in a product-focused environment.
Strong React fundamentals, including component architecture, state management, and performance.
Solid HTML5 and CSS3 skills and the ability to build clean, responsive interfaces.
Go backend experience, including REST API development, middleware, and service patterns.
PostgreSQL experience with schema design, query writing, and migrations.
GraphQL familiarity sufficient to read and reason about resolvers and understand N+1 patterns and common pitfalls.
Familiarity with integration patterns such as webhooks or third-party API design.
Some exposure to broader backend concerns such as caching, rate limiting, or asynchronous processing.
Experience with GitHub Actions or similar CI/CD tooling.
US person status, as defined in the posting, is required for access to export-controlled information.
