Job description

We’re looking for a Senior Software Engineer with strong Rust and Python expertise and a product-focused mindset to help build a new class of AI-powered transpilation and code generation tools. These tools bridge the gap between algorithm development and embedded deployment, leveraging the latest in Generative AI, Static Analysis and Formal Verification.

This is more than a backend role, we’re seeking engineers who can think end-to-end:

from understanding user needs and UX, to delivering robust and scalable systems across the full stack.

Requirements

  • 5+ years of professional software development experience.
  • Expert-level proficiency in Rust and Python.
  • Strong experience delivering entire software products, not just isolated services you understand how frontend, backend and APIs come together.
  • Product-oriented mindset - you think about UX, system behavior and real-world impact.
  • Comfortable working cross-functionally with design, product and sometimes even customers.
  • Strong software engineering practices: version control, code review, testing, continuous integration and deployment.
  • Previous experience with greenfield projects and production build experience
Why Code Metal?
  • Mission with impact: your visuals steer the conversations that shape tomorrow’s force.
  • Velocity: tight loops, tiny teams - design in the morning, deploy by evening.
  • Ownership: no spectators - every engineer ships code that matters.

Benefits

  • Health care plan with 100% premium coverage, including medical, dental, and vision.
  • 401k with 5% matching.
  • Paid Time Off (Uncapped Vacation, plus Sick & Public Holidays).
  • Flexible hybrid work arrangement.
  • Relocation assistance for qualifying employees.
