• Proven ability to troubleshoot and resolve critical incidents quickly under pressure, during market hours
• Expert-level Python (object-oriented design, multithreaded/async programming) and strong
JavaScript/TypeScript with Angular
• Linux systems knowledge; databases (PostgreSQL) and SQL
• CI/CD experience: Jenkins, Docker, Kubernetes (Helm), Git, testing
• Nice to have: hands-on experience building and deploying machine-learning pipelines and integrating AI-assisted tooling into operational workflows
