About the role

We are looking for a Research Engineer to help build frontier AI systems and the infrastructure behind them. This is not a narrow role. You will work across multiple parts of the system, collaborating with researchers and engineers to turn ideas into production systems.

doubleAI is building next-generation reasoning and code-optimization agents that push the frontier of artificial expert intelligence. Our models are built on world-class infrastructure: large-scale GPU clusters, state of the art agentic cloud environments, and CI/CD pipelines.

We are looking for someone with strong fundamentals, algorithmic problem solving capabilities, hands-on engineering skills, a collaborative mindset, and a desire for continuous learning. We value people who are comfortable moving between code, systems, algorithms, and problem domains.

02

What you'll do

  • Write production-grade code powering frontier AI systems.

  • Work on performance, scalability, and reliability of distributed systems.

  • Collaborate with researchers and engineers to turn ideas into systems that run.

  • Improve tooling, infrastructure, and developer workflows.

03

What we're looking for

  • Engineers with a generalist mindset and a track record of hands-on work across different areas of software.
  • People who are comfortable moving between code, systems, algorithms, and problem domains.
  • Strong fundamentals, sound judgment, and the ability to learn quickly.
  • Candidates who can point to concrete evidence of excellence.

Nice to have

  • Experience with technologies used throughout our stack, including Python, C++, PyTorch, CUDA, Rust, Linux, containers, Kubernetes, SLURM, AWS, GCP, Prometheus, Grafana, vLLM, or distributed systems.
  • Experience working across both research and engineering environments.
  • Experience building, scaling, or operating AI systems and infrastructure.
