About the role

Key responsibilities & impact

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.
Create interfaces for configuring agents, managing connections and policies, reviewing runs, and inspecting logs, traces, costs, and audit history.
Implement authentication, authorization, role-based access, secrets integration, and audit events; partner with Governance, Risk and Compliance on application security findings and engineering evidence.
Adapt application configuration and dependencies for customer-managed cloud, private-network, and on-premises environments; work with DevOps/SRE on packaging, deployment prerequisites, and validation.
Own quality through code reviews, unit and integration tests, end-to-end tests, workflow evaluations, and regression coverage.
Diagnose and resolve partner-reported defects across UI, APIs, SDK, data stores, and runtime services; add telemetry and validate fixes.
Support releases, upgrades, and ongoing application maintenance, including federal deployments; maintain API/SDK compatibility and coordinate security fixes.
Document architecture, setup, limitations, and troubleshooting; provide partner walkthroughs and knowledge transfer; share reusable solutions and mentor engineers.

Requirements

What you’ll need

U.S. citizenship is required.
10+ years of software engineering experience, with a track record of shipping and supporting production applications; scope and technical leadership appropriate to Senior or Staff level.
5+ years of hands-on full-stack development spanning modern web frontends, backend services, APIs, and databases.
Strong frontend skills with TypeScript/JavaScript and React, Next.js, or comparable frameworks, including state management, API integration, and clear, accessible user experiences.
Strong backend engineering skills in Python, TypeScript/Node.js, Go, Java, or a similar language, including API design, service integration, validation, and error handling.
Experience designing data models and working with relational databases, migrations, caching, and asynchronous or event-driven processing.
Experience implementing authentication, authorization, secure API access, secrets handling, and audit logging in production applications.
Hands-on experience with automated testing, code review, Git, containers, CI/CD, and deploying or troubleshooting applications in cloud or Kubernetes environments.
Ability to debug across browser, service, API, and data layers using logs, metrics, and traces, and to own issues through validated resolution.
Strong technical judgment, clear written and verbal communication, and experience translating ambiguous customer requirements into maintainable solutions and useful documentation.
Experience using AI-assisted engineering tools to improve implementation, testing, troubleshooting, or code review, with careful validation of the resulting changes.
Prior full-stack software engineering experience supporting national security, defense, federal agencies, or other government programs (strongly preferred).
An active U.S. government security clearance (strongly preferred).
Experience with federal application security and delivery requirements, such as STIG hardening, NIST controls, RMF/ATO evidence, FedRAMP, or DoD impact-level environments (strongly preferred).
Experience integrating identity providers such as Keycloak using OAuth/OIDC, or implementing fine-grained access and sensitive-data controls (strongly preferred).
Experience building AI/LLM applications, agent integrations, RAG, tool/MCP connections, evaluations, or workflow systems such as Temporal (strongly preferred).
Customer-facing or forward-deployed engineering experience across multiple partner organizations, including onboarding, technical handoffs, and ongoing support (strongly preferred).
Experience adapting applications for government cloud, restricted-network, or on-premises deployments, including Second Front or comparable federal delivery platforms (strongly preferred).
