Systems-oriented mindset with the ability to bring structure to ambiguous technical challenges.

Experience designing pipelines, feedback loops, iterative systems, or large-scale developer tooling.

Strong communication skills and the ability to collaborate with technical and non-technical stakeholders.

Preferred Qualifications Experience with Rust, C++, C, or Fortran.

Experience modernizing legacy systems or migrating applications to cloud-native architectures.

Background in Dev

Ops, CI/CD pipelines, testing frameworks, simulation systems, benchmarking, or validation tooling.

Experience working with engineering, scientific, mathematical, or simulation software.

Familiarity with cloud platforms and distributed systems.

Interest in emerging AI development patterns, agentic workflows, and software transformation technologies.

What Success Looks Like Successful candidates will demonstrate the ability to: Modernize existing systems rather than only building greenfield solutions.

Make thoughtful tradeoffs between performance, reliability, latency, maintainability, and cost.

Apply AI in practical, production-oriented ways.

Navigate ambiguity while maintaining engineering rigor.

Build systems that continuously improve and scale over time.

Who Thrives in This Role Developers who enjoy applying AI to real-world engineering challenges and measuring success through production impact.





Builders who are comfortable working within large, evolving codebases.

Generalists who enjoy moving across languages, tools, and technical domains.

Developers who embrace continuous learning as AI capabilities and modernization approaches evolve.
