Job summary

Mitratech is seeking a Senior Full Stack Engineer to own features across a mature Rails monolith and a fleet of Go microservices, delivering end-to-end capabilities in a security- and performance-conscious environment.

You will design and ship candidate portals, partner flows, I-9 workflows, and admin tools, while extending ATS integrations and orchestrating vendor search pipelines. Embrace AI-powered improvements and maintain high-quality, well-tested code.

Qualifications

• Strong production experience with b2b SaaS applications.
• Solid Go skills, or equivalent backend experience with HTTP services, background workers, and concurrency.
• Strong PostgreSQL skills and good instincts for relational data modeling.
• A track record building and consuming REST APIs and third-party integrations (webhooks, OAuth, SFTP); mcp experience is a plus.
• Comfort with server-rendered frontends (ERB/HTML/CSS) and a habit of writing well tested code.

Responsibilities

• Design and build features across the Rails monolith and Go microservices — candidate portals, partner flows, I-9 workflows, and internal admin and adjudication tools.
• Extend our ATS and partner integrations.
• Orchestrate asynchronous vendor searches and reporting pipelines.
• Use AI throughout your workflow, pair with AI coding assistants, leverage automated AI code review on every PR, and use agentic tools to move faster without cutting corners.
• Help build AI-powered features into the platform: intelligent document parsing, structured extraction from vendor records, and smarter automation of screening and adjudication workflows.
• Own the full lifecycle of your work: build it, test it (including major UX paths), get it reviewed, ship it, and monitor it.
