RYZ Labs is looking for a highly skilled Staff Software Engineer to join one of our clients’ teams. In this role, you will own critical parts of our AI agent platform. You'll design systems, write code, and ship. As the platform scales, so does your scope.

Qualifications:

5+ years building production software, with increasing ownership over architecture and technical decisions
Strong experience with Python and/or TypeScript in production
Experience with React and modern frontend frameworks (Next.js preferred)
AI: Multi-model (OpenAI, Anthropic, Google), document understanding/OCR
Infrastructure: AWS, Terraform, Docker
You have built and shipped systems that serve paying enterprise customers
You have designed systems that other engineers built on successfully.
You have worked with LLMs/AI in production — systems with real users and real failure modes, not side projects

Key Responsibilities:

-Own defined parts of the platform architecture — boundaries are set with the principal engineer
as the platform grows
- Design and build the AI agent pipelines — document parsing, extraction, analysis, and pricing
- Make infrastructure decisions across AWS that support 5x growth without 5x cost
- Write production code daily
- Define and enforce engineering standards through CI, linters, and code review
- Build the data pipelines that process DOT state pricing, bid documents, and historical project
data
- Work directly with the founder and the existing principal engineer on product direction and
technical tradeoffs
- Set the quality bar through code review on every significant PR
- Design systems that fail gracefully when AI outputs are wrong or incomplete
- Build monitoring and observability so we know what´s breaking before customers do
- Contribute to hiring decisions as we grow
