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 one of our global research teams. In this role, you will collaborate closely with the team's researchers to maintain the team's infrastructure as they relate to live trading outcomes. This is a hybrid development and research and trading operations position. You'll be responsible for ensuring the reliability of the team's research pipeline—diagnosing idiosyncratic and fixing observed issues in research and trading systems, 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 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. Experience solving challenging problems through code in a live trading environment. 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. This position is connected to all facets of the "research to risk on” process and is accordingly well suited to people who wanting to learn all facets of the big picture. 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.

That number includes positions in India (9,577), Poland (3,429), the United States (1,753), Singapore (787), and Brazil (779). If you're looking to move or work remotely, check which countries match your goals — then filter WorkMundi by location to see what's actually hiring near you.
Most developer ads you'll see are written in English: 18,397 of the 24,795. That doesn't tell you whether the job itself requires you to speak English or work in English daily, so read each posting carefully. Don't assume the language of the ad matches the language of the team.
The employers posting the most developer roles are Link Group (369 jobs), Upvanta (257), jobgether (226), and OfferZen (212). If you're applying to any of these, research their hiring patterns. They move fast and post often, which means they're either scaling hard or replacing people who didn't fit.
In your interview, expect this: 'Walk me through the last time you had to debug something that took you more than an hour. What was it, what did you try first, and what would you do differently?' Hiring managers ask this to see if you think systematically or just try random fixes. Have a real example ready with specifics.
