## Job description

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.

As part of our Central Ops and Reliability Engineering (CORE) team, you'll play a critical role in managing our real-time production trading environment. We operate a follow-the-sun model globally to monitor, triage, troubleshoot, and deploy changes to our production trading systems. In this role, you'll develop deep technical and operational expertise across all areas of our trading platform. You'll proactively monitor and troubleshoot systems, deploy changes while minimizing operational risk, and implement tools and processes that drive continuous improvement. Join a team that operates at the heart of Jump's trading infrastructure, where you'll have direct impact on system performance and reliability while working with cutting-edge technology at scale. This role offers unique exposure to all aspects of our trading platform and the opportunity to work directly with traders and technologists across the firm.

As a CORE Weekend Warrior, you will work a 4-day workweek role, with one weekend day (Saturday or Sunday) as part of your schedule. During onboarding and training, you’ll initially work a standard Monday–Friday week before transitioning to the 4-day schedule (Wednesday–Saturday or Sunday–Wednesday). Candidates must be comfortable with and prepared for this arrangement. Flexibility and reliability to support weekend trading are essential to success in this role. On weekends, you will work shifts that overlap with colleagues in the other time zone (APAC and US). Other teams have a similar setup, so you will join a virtual ‘weekend warrior’ team online at the weekend in your time zone. Even at weekends, Jump’s systems are heavily automated so most of your time will be working on project work – but you will be available for immediate troubleshooting and support as required.

What You'll Do:

- Own the production environment, driving performance, reliability, and operability through continuous improvement
- Proactively monitor and troubleshoot large-scale trading systems and exchange connectivity
- Build and maintain our site reliability toolkit for the production trading system including configuration management, process management, deployment, monitoring, data collection, and analysis
- Leverage firm-wide metrics to improve scalability and system performance
- Partner with traders, Risk Management, and Operational Trading Support teams to communicate technology changes, coordinate deployments, and manage incidents
- Collaborate across the technology organization to analyse and troubleshoot complex system problems
- Work with Clearing team to reconcile trades and position breaks
- Assess and manage operational risk when deploying changes to production
- Define and document processes and procedures
- Provide mentorship and cross-training to other technical operations engineers
- Additional responsibilities as business needs evolve

Skills You’ll Need:

- Degree in Computer Science, related field, or equivalent professional experience
- At least 5+ years of relevant experience in IT operations (DevOps, SRE, Linux Systems Engineering, or Network Engineering)
- At least 3+ years of experience with Python and shell scripting
- Strong understanding of the Linux operating system, including network and system configuration, kernel internals, scheduling, and performance tuning
- Strong understanding of networking concepts such as routing, multicast, LLDP, VLANs, and Ethernet
- C++ experience is a plus
- Rigorous, detail-oriented approach to operations
- Deep sense of ownership and ability to meet business priorities with urgency
- Reliable and predictable availability
- Ability to handle shared operational and periodic on-call duties

Benefits include:

- Private Medical, Vision and Dental Insurance
- Travel Medical Insurance
- Group Pension Scheme
- Group Life Assurance and Income Protection Schemes
- Paid Parental Leave
- Parking and Commuter Benefits

Annual Base Salary Range:

€150.000 - €175.000 EUR
