About Us Integrate is a Seattle-based company building multiplayer project management software for the world’s most ambitious machines. 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. Our Solution Traditional project management tools weren’t designed for the speed, scale, and interdependence of modern hardware development. Integrate is purpose-built for this new reality. 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. About the Role We’re hiring a Backend Engineer to join a small, high-ownership engineering team building the infrastructure layer of Integrate’s platform. This isn’t a maintenance role — you’re coming in to help us scale. The problems you’ll work on are real and immediate: distributed system performance, data federation at scale, and building the architecture that lets Integrate grow with its increasing customer base. You’ll work closely with engineers who care deeply about craft, move fast, and aren’t afraid to make hard calls. If you’ve built systems that handle serious consumer or commercial load — cloud migrations, microservice transitions, distributed data pipelines, event-driven architecture — this is the role for you. What You’ll Work On Design and scale distributed backend systems handling high-throughput, real-time data across a complex dependency graph Own performance profiling and debugging across our Go and Rust services — identify bottlenecks and ship fixes Contribute to our data federation architecture, including S3 integration, graduation pipelines, and downstream data services Build and evolve gRPC service interfaces and REST/JSON APIs consumed across internal and external surfaces Work across SQL and NoSQL data stores — schema design, query optimization, and durability patterns Drive infrastructure decisions in collaboration with platform engineers and technical leads Instrument, observe, and debug production systems — on-call, root cause analysis, and incident follow-through Tech Stack You’ll be working primarily in Go, with Python for tooling and data workflows. Our stack includes gRPC, REST/JSON, GraphQL, PostgreSQL, NoSQL stores, and Kubernetes-managed infrastructure. We use Terraform for infra-as-code. Experience We're looking for someone with a strong foundation in distributed backend systems — though we don't expect you to check every box. Here's the kind of background that sets you up well: 2–5+ years of backend engineering experience, with a focus on distributed or high-availability systems Production experience in Go; Python for tooling or data workflows Familiarity with gRPC and REST/JSON API design at scale — bonus points for experience with gRPC design patterns, binary serialization, or API gateway-layer GraphQL Experience with both SQL (PostgreSQL) and NoSQL data stores in production Kubernetes in real environments — deployment, scaling, resource management, debugging Exposure to cloud infrastructure (AWS, GCP, or Azure), particularly around compute, storage, and data services; Terraform or other IaC tooling is a plus A track record on complex system work: monolith-to-microservice transitions, cloud migrations, data pipelines, or consumer-scale workloads Strong debugging instincts — you can read a flame graph, find a bottleneck, and ship a fix; experience with load testing or chaos engineering is a nice addition Background in ecommerce, fintech, or other consumer-scale SaaS is helpful but not required Who You Are You operate well with autonomy and ambiguity. You’re the kind of engineer who runs toward hard problems, and you’re comfortable in an environment where the right answer isn’t always obvious on day one. You have strong opinions, but you hold them lightly — you can articulate your reasoning, hear a counterpoint, and update. You care about making the system better, not being right. You’re excited to learn and grow in all facets. You’re joining a team that’s building in the open — that means context-sharing, code review that actually teaches something, and the expectation that everyone is leveling up together. Why Join Us? 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.  ITAR Requirement This position requires access to information protected under US export control laws, including the International Traffic in Arms Regulations and/or the Export Administration Regulations.  As such, US person status (including US citizens, U.S. permanent residents, individuals granted U.S. asylum status, or individuals admitted in U.S. refugee status) is a required qualification for this position. Equal Opportunity Employer We are an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex (including pregnancy), sexual orientation, gender identity and/or expression, national origin, protected veteran status, disability, genetics, or citizenship status (when otherwise legally authorized to work and access export-controlled data) and will not be discriminated against on the basis of such characteristics or any other status protected by the laws or regulations in the locations where we operate.
