About the Role 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 What you'll do You will work on: A shared platform powering all Trase deployments Multi-service systems with complex integration points Development and testing workflows that must reflect real production behavior Tooling that enables safe iteration in security- and compliance-sensitive environments You will: Design and maintain local development environments that mirror production behavior as closely as possible Build and operate build systems, CI pipelines, and test orchestration for multi-service systems Own integration and end-to-end testing infrastructure, including: Test environments and fixtures Cross-service test coordination Flake detection and reduction Develop internal tooling (CLI, SDKs, scaffolding) that standardizes how engineers interact with the platform Create repeatable workflows for building, testing, and deploying changes across services Improve developer feedback loops (build times, test reliability, debugging workflows) Partner with DevOps/SRE to ensure development workflows align with production reliability and deployment systems Establish and maintain runbooks, templates, and onboarding systems that reduce ramp time and inconsistency Staff-level technical leadership Define and drive the developer experience strategy across Trase
