Staff, Full Stack Engineer

3 Days Old

About the Role
As a Staff Engineer, you'll own end-to-end features across our backend services (Ruby on Rails or TypeScript/Node) and our Angular/TypeScript front end. You'll work under minimal supervision, troubleshoot complex problems, and help shape our core monolith and emerging TS microservices while collaborating closely with product, design, and QA. You will potentially work with AI enabled tools and services. However you do not need deep data science knowledge.

Design, build, and maintain scalable Rails or TypeScript/Node services and RESTful APIs
Implement and extend Angular/TypeScript UI components for web experiences
Optimize PostgreSQL queries and service performance
Collaborate with cross-functional squads to define requirements and deliver features
Potentially work on ai agents, mcp servers and various AI enabled tools and frameworks
Identify and drive process, architecture, and toolchain improvements
Mentor junior engineers through code reviews and pair-programming
Serve as a technical lead on complex projects, balancing scope, risk, and engineering quality.
What does success look like?
30 days: Ship a backend feature (Rails or TS) end-to-end and demo it to the team
60 days: Lead a cross-team API enhancement and propose a performance or scaling or testability refactor
90 days: Lead a system-level architectural improvement (e.g., introduce a TypeScript microservice or refactor a critical service for scalability), including a clear design, implementation, and rollout plan in place or executed against..
