Co-founded in 2023 by Joe Laws and Grant Verstandig , Trase Systems is AI, Uncomplicated. Trase empowers enterprise leaders to harness the full potential of AI without the associated complexity and risks. We are an end-to-end solution for deploying, managing, and optimizing AI in the enterprise.

About the Role

As a Senior or Staff Full Stack Software Engineer at Trase, you will build and support software for Red Cell Federal (RCF), Red Cell Partners (RCP), and RCP incubations and portfolio companies. You will join Trase's dedicated RCF/RCP support team, delivering user interfaces, backend services, APIs, and integrations with a strong focus on federal, government, and national security programs. Red Cell Partners is an investment and incubation firm that builds and supports technology companies, including Trase. Red Cell Federal is our federal-focused partner within that ecosystem. This role helps RCF and other RCP partner companies adopt Trase OS and build secure AI applications for their missions. This is a hands‑on role with ownership from requirements through production support. You will work directly with partner engineers, Product, the dedicated TPM and DevOps/SRE engineers, Trase Platform Engineering, and GRC to deliver working solutions across the frontend, backend, and integration layers. The level will reflect your experience and demonstrated scope. Senior engineers will independently own complex features and partner integrations end to end. Staff engineers will also lead architecture across engagements, establish reusable engineering patterns, and mentor engineers.

Why this Role is Needed

RCF and RCP companies need software that works within their applications, security controls, and deployment environments. Success requires intuitive user experiences, reliable APIs and agent workflows, clear audit trails, and dependable integrations. You will close partner‑specific functionality gaps, diagnose issues across application and platform boundaries, and deliver small, validated increments. You will also turn recurring partner needs into reusable improvements with Trase's platform team.

What You'll 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.
