Trase is at the forefront of AI Agent innovation, topping the Hugging Face GAIA Leaderboard for Generalized AI Assistants, ahead of industry giants such as Google, Meta, Microsoft, and OpenAI. We are leveraging our cutting-edge technologies to develop mission-critical agentic applications in complex industries such as Healthcare, Oil & Gas, and National Security. \nAbout the Role\nAs 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.\nRed 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.\nThis 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.\nThe 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.\nWhy this Role is Needed\nRCF 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.\nYou 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.\nWhat You'll Do\nBuild full-stack features for RCF/RCP partners, from responsive UI interfaces and administrative tools to backend services, data models, and production integrations.\nWork 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.\nIntegrate 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.\nBuild reliable agent and workflow integrations, including asynchronous execution, event streaming, state handling, retries, timeouts, and error recovery. Preserve correctness and data integrity across failures.\nCreate 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.\nImplement 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.\nAdapt 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.\nOwn 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.\nDiagnose 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.\nSupport 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.\nDocument architecture, setup, known limitations, and troubleshooting steps; provide partner walkthroughs and knowledge transfer. Share reusable solutions with the platform team and mentor other engineers.\nRequired Qualifications\nU.S. citizenship is required.\n10+ 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.\n5+ years of hands-on full-stack development spanning modern web frontends, backend services, APIs, and databases.\nStrong frontend skills with TypeScript/JavaScript and React, Next.js, or comparable frameworks, including state management, API integration, and clear, accessible user experiences.\nStrong backend engineering skills in Python, TypeScript/Node.js, Go, Java, or a similar language, including API design, service integration, validation, and error handling.\nExperience designing data models and working with relational databases, migrations, caching, and asynchronous or event-driven processing.\nExperience implementing authentication, authorization, secure API access, secrets handling, and audit logging in production applications.\nHands-on experience with automated testing, code review, Git, containers, CI/CD, and deploying or troubleshooting applications in cloud or Kubernetes environments.\nAbility to debug across browser, service, API, and data layers using logs, metrics, and traces, and to own issues through validated resolution.\nStrong technical judgment, clear written and verbal communication, and experience translating ambiguous customer requirements into maintainable solutions and useful documentation.\nExperience using AI-assisted engineering tools to improve implementation, testing, troubleshooting, or code review, with careful validation of the resulting changes.\nStrongly Preferred\nPrior full-stack software engineering experience supporting national security, defense, federal agencies, or other government programs.\nAn active U.S. government security clearance.\nExperience with federal application security and delivery requirements, such as STIG hardening, NIST controls, RMF/ATO evidence, FedRAMP, or DoD impact-level environments.\nExperience integrating identity providers such as Keycloak using OAuth/OIDC, or implementing fine-grained access and sensitive-data controls.\nExperience building AI/LLM applications, agent integrations, RAG, tool/MCP connections, evaluations, or workflow systems such as Temporal.\nCustomer-facing or forward-deployed engineering experience across multiple partner organizations, including onboarding, technical handoffs, and ongoing support.\nExperience adapting applications for government cloud, restricted-network, or on-premises deployments, including Second Front or comparable federal delivery platforms\nIf you want to be on the cutting edge of technology, building AI solutions for the future, and are up for a challenge, let’s talk!\nSalary Range: $180,000-240,000.
