The role

What you will do

Build full-stack features for RCF/RCP partners, from responsive UI interfaces and administrative tools to backend services, data models, and production integrations.
Work directly with partner engineers and Product to clarify use cases, reproduce issues, define acceptance criteria, and deliver small increments. Surface scope, dependencies, and risks with the TPM before committing dates.
Integrate partner applications and agents with Trase OS APIs and SDKs, external APIs, MCP tools, and model-provider endpoints. Provide working examples and clear integration documentation.
Build reliable agent and workflow integrations, including asynchronous execution, event streaming, state handling, retries, timeouts, and error recovery. Preserve correctness and data integrity across failures.
Create usable interfaces for configuring agents, managing connections and policies, reviewing runs, and inspecting logs, traces, costs, and audit history. Make failures and recovery actions understandable to users.
Implement authentication, authorization, role-based access, secrets integration, and audit events across frontend and backend services. Partner with Governance, Risk and Compliance on application security findings and engineering evidence for applicable federal requirements.
Adapt application configuration and dependencies for customer-managed cloud, private-network, and on-premises environments. Work with DevOps/SRE on packaging, deployment prerequisites, and end-to-end validation.
Own quality through code reviews, unit and integration tests, end-to-end tests, representative workflow evaluations, and regression coverage. Verify application behavior in the target environment before partner handoff.
Diagnose and resolve partner-reported defects across the UI, APIs, SDK, data stores, and runtime services. Add useful telemetry, support incident investigation, and validate fixes with partners.
Support releases, upgrades, and ongoing application maintenance, including federal deployments such as Second Front where applicable. Review and integrate partner contributions, maintain API/SDK compatibility, and coordinate security fixes with platform and DevOps/SRE owners.
Document architecture, setup, known limitations, and troubleshooting steps; provide partner walkthroughs and knowledge transfer. Share reusable solutions with the platform team and mentor other engineers.
