Location: Seattle, WA area As a Staff Developer Experience Engineer (DevEx), you will own the systems, tooling, and workflows that enable engineers to build, test, and ship on Trase OS quickly and safely. As the first DevEx hire, you will build the base of the platform and team. This is a core platform engineering role, not internal tooling support. You will design and operate the development environment, build systems, and integration infrastructure that allow teams to work effectively in a distributed, multi-service system with strict reliability and security constraints. Your work directly determines engineering velocity, system safety, and the ability to scale the team without increasing risk. Why this role is needed Trase OS is a complex, evolving platform with long-lived workflows, multiple services, and deployments across environments with varying security requirements. As system complexity grows, developer friction and release risk become the primary bottlenecks. Without strong DevEx ownership: Cross-service changes become slow and error-prone Integration issues surface late (or in production) Local development diverges from production reality Each team reinvents workflows instead of building on shared foundations This role exists to: Create paved roads for development and testing Ensure engineers can make changes confidently across services and environments Turn platform complexity into repeatable, reliable developer workflows
