About the Role

As a Staff Engineer, you’ll own end-to-end features across one or more of our backend services, agentic frameworks, AI Pipelines and front end. You’ll work under minimal supervision, troubleshoot complex problems, come up with innovative designs and optimizations and help shape our microservices architecture while collaborating closely with product, design, and QA. You will work with high performance, mission critical tools and services. You do not need to have experience training or developing ML models/algorithms, but experience with them is a plus.

What you’ll do

• Design, build, and maintain scalable Ruby/Rails, TypeScript/Node, and Python services and RESTful or gRPC APIs that integrate with agentic GenAI systems

• Optimize MongoDB and PostgreSQL queries and service performance

• Collaborate with cross-functional squads to define requirements and deliver features

• Identify and drive process, architecture, and toolchain improvements

• Mentor junior engineers (code reviews, pair-programming etc)

• Serve as a technical lead for complex projects, balancing scope, risk, and not compromising deliverable quality.

What does success look like?

• 30 days: Ship a backend feature and demo it to the team

• 60 days: Potentially lead a cross-team API enhancement or propose a performance or scaling or testability improvement

• 90 days: Lead a system-level architectural improvement or completely new deliverable (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.

Who You Are

• 8+ years building web services or full-stack applications

• Strong hands-on experience in Ruby/Rails, TypeScript/Node, Python or similar backends

• Deep understanding of APIs, PostgreSQL, and some performance tuning

• Proven ability to balance short-term delivery with long-term technical investments and continuous improvement of quality.

• Comfortable working in a fast-paced, ambiguous environment where requirements evolve over time.

• Excellent problem-solving, communication, and collaboration skills

• Some knowledge of of AI/ML is desired but not a requirement

• Experience with LLMs or AI-driven toolchain (Langchain/Langgraph) is highly desirable
