We are seeking a hands-on Staff Engineer / Technical Lead to drive full-stack development using C#/.NET, React, TypeScript, AWS, and generative AI. This is an individual contributor leadership role, with 60–80% of the time dedicated to writing production code.


Key Responsibilities

  • Build and ship end-to-end features using C#/.NET and React/TypeScript.
  • Design and develop scalable, distributed AWS-based systems, APIs, event-driven services, and cloud infrastructure.
  • Lead technical architecture, code reviews, engineering quality, and mentoring while remaining hands-on.
  • Optimize React applications for performance, testing, state management, and scalability.
  • Integrate production-ready AI/LLM capabilities, including APIs, RAG, vector databases, and AI agents.
  • Own CI/CD, observability, reliability, and production performance.


Required Qualifications

  • 6–10 years of software engineering experience, with technical leadership experience.
  • Strong, recent hands-on expertise in C#/.NET, React, and TypeScript.
  • Proven experience shipping production code across both frontend and backend.
  • Solid AWS experience with distributed systems, messaging, caching, databases, and CI/CD.

  • Terraform/CloudFormation and infrastructure automation experience.
  • Experience modernizing large React applications.


Ideal Candidate: A hands-on technical leader who enjoys coding, owns architecture for a product area, mentors engineers, and has delivered real-world AI integrations. This is not a people-management or research-focused role.
