Senior Full Stack Software Engineer

React, Golang, GraphQL, REST, PostgreSQL, GitHub Actions.

Our environment also includes Tailwind CSS.

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; Apollo Client familiarity is a plus
• 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; bonus if you've worked with complex or graph-structured data models
• 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
• Background in B2B SaaS, defense tech, or complex enterprise environments is a plus — as is comfort working in a product and architecture that's still taking shape

You're comfortable across the stack — whether that's a component tree or an API route handler.

When specs are ambiguous, you ask good questions, get yourself unblocked, and move forward.

You care about the experience of the people using what you build.

That means thinking about the user problem before the implementation, pushing back when something feels off, and treating UX quality as your responsibility regardless of where it sits in the stack.

You hold your work to a high standard — not because you have to, but because it matters to you.

You communicate openly, surface issues early, and show up when things get complicated.

We're all learning here.

Integrate is a place where everyone is building something they haven't built before — that's kind of the whole point.

You'll find plenty of room to grow.

Join us at the forefront of deep tech, building the software infrastructure that powers the next generation of hardware innovation.

We're a tight-knit, ambitious team with a vision to transform how humans build.

You'll have the opportunity to shape the technical foundation of a company working with customers building rockets, aircraft, autonomous systems, and the infrastructure of the modern world.

Here, you'll have real influence over architecture and technical direction in ways that simply aren't possible at a larger company — and you'll do it alongside a team of high performers who will push you to grow faster than you would anywhere else.

We focus on the hardest coordination problems in deep tech like rocket launches and advanced manufacturing, where progress depends on seamless collaboration across companies.

Increasingly, this work sits at the intersection of two of the most consequential forces shaping the modern world: defense and artificial intelligence, where both the pace of innovation and the stakes of execution are exceptionally high.

Integrate enables teams to collaborate with vendors, customers, and partners as fluidly as modern tools support internal teams.

Our mission is to modernize how organizations build together in the emerging deep tech economy, reducing friction, misalignment, and unnecessary work at every step.

We provide a platform that brings clarity and structure to complex, cross-organizational programs helping teams communicate effectively, stay aligned, and move faster with confidence.

By improving how critical information is shared and decisions are made, we enable organizations to focus on what matters most: building the future.

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 show up as a full participant in product thinking, not just an executor of specs.

That means understanding the user problem behind the work, speaking up when something doesn't serve them well, and treating polish and UX quality as engineering requirements.

We're a small team.

There's no handoff culture here.

If you build it, you own it.

• Build and iterate on React-based UI surfaces that make complex project workflows legible and fast for end user
• Design and maintain REST APIs and GraphQL layers in Go, working across internal and external consumers
• Own and evolve data models in PostgreSQL — schema design, query optimization, and migration management
• Contribute to our GraphQL integration layer, ensuring resolvers are well-structured and performant
• Build and maintain integration services in Go that connect internal systems and external APIs, owning the full contract from interface design to error handling and observability.
• Write and maintain CI/CD pipelines using GitHub Actions including build, test, and deployment stages across environments.
• Ship clean, tested, maintainable code across the stack — and leave things better than you found them
