• Strong problem-solving skills and a willingness to learn through exploration and feedback

• Self-motivated, proactive, and adaptable mindset

• Interest in improving processes and systems, with openness to support in implementation

• Remote US, with a preference in the West Coast or Mountain time zones

Bonus points for

• Experience with Golang and Rust

• Experience with HPC environments, workload manager (such as Slurm, PBS, PBS Pro), and hetergeneous hardware integration

• Understanding of asynchronous programming techniques

• Experience leveraging AI-assisted development tools (e.g., code generation, code review, testing, or documentation) and building AI-powered solutions to improve engineering productivity or automate workflows

• Experience building and maintaining CI/CD pipelines using tools such as Jenkins, Spinnaker, or similar

• Experience developing and deploying software in cloud environments such as AWS
