Quantitative Developer | Trading Team

About the Role

Jump Trading Group is committed to world class research. We empower exceptional talents in Mathematics, Physics, and Computer Science to seek scientific boundaries, push through them, and apply cutting edge research to global financial markets. Our culture is unique. Constant innovation requires fearlessness, creativity, intellectual honesty, and a relentless competitive streak. We believe in winning together and unlocking unique individual talent by incenting collaboration and mutual respect. At Jump, research outcomes drive more than superior risk adjusted returns. We design, develop, and deploy technologies that change our world, fund start-ups across industries, and partner with leading global research organizations and universities to solve problems.

We are seeking a Quantitative Developer to help support a New York based trading team. In this role, you will collaborate closely with the team's researchers to maintain the team's infrastructure and production systems. This is a hybrid development and operations position. You'll be responsible for ensuring the reliability of the team's production pipeline—diagnosing and fixing recurring issues from a systems perspective, making jobs more stable, and stepping in when things go wrong. We are looking for a mature, self-directed engineer who can operate independently and handle high-stakes situations with confidence. The more efficiently you can automate and stabilize operations, the more time you'll have to focus on performance-oriented development work.

What You'll Do

• Own live production operations: Ensure trading strategies are connected to all markets, data is available in the correct volume and format, and the optimizer is running as scheduled.
• Manage and evolve the monitoring system: Act as the primary escalation point for error messages and failed jobs. Chase problems identified by the monitoring system to their source—identifying bugs, writing fixes, and resolving issues yourself rather than forwarding them on. Maintain a big-picture understanding of all processes overseen by the monitoring system.
• Improve pipeline efficiency and performance: Investigate recurring pipeline issues and solve them at a systemic level. Optimize performance-critical workloads—for example, making ML models and GPU jobs run faster and more efficiently.
• Engage in full-cycle development: Contribute across research, coding, testing, and deploying systems into production. Provide direct support to end users, troubleshoot issues, and manage system upgrades. Design and maintain robust testing, deployment, rollout, and rollback processes.
• Other duties and responsibilities assigned.

Skills You'll Need

• At least 2-5+ years of experience in a production engineering or trade support function, with a track record of solving challenging problems through code with real metrics and impact.
• Strong software development skills in Python (primary) and C++, with the ability to build efficient, modular, and reliable systems. A performance-oriented mindset is essential.
• Strong production engineering skills in Linux and Bash, including scripting to get systems up and running, troubleshooting, monitoring, and operating real-time systems under pressure.
• Hands-on debugging ability: Follow error messages to their source, identify the underlying problem, and begin the fix— This is a role for someone who resolves issues, not someone who escalates them.
• Maturity and independence: Comfortable operating autonomously in a high-stakes environment where downtime carries real consequences.
• Reliable and predictable availability to ensure smooth operations of production systems, including responsiveness during trading hours when needed.
• Strong learning ability, intellectual curiosity, versatility, and originality combined with a pragmatic outlook.
• Ability to reason through quantitative problems and communicate effectively with quantitative researchers and engineers.

Nice to Have

• Understanding of neural networks and experience optimizing ML/GPU workloads for performance.
• Experience with modern infrastructure and deployment practices such as CI/CD, Infrastructure as Code, containerization, and observability tooling (e.g., GitLab, Jenkins, Terraform, Ansible, Docker, Kubernetes, Prometheus, Grafana).
• Two or more years working with industrial-grade codebases in Python and C++.
• Familiarity with distributed large-scale systems.
