Cloud Systems Engineer

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 building a small, high-impact team to design and run infrastructure that operates outside Jump's primary environment. This is a broad remit: cloud, production systems, and HPC-style workloads all fall within scope, with sound security practices built in throughout. We are looking for a true generalist who can design systems from the ground up, operate them with little direction, and dig deep when things break.

What you’ll do:

• Design, build, and maintain cloud infrastructure that operates independently of Jump's on-premises environment.
• Architect resilient, reliable systems, with security considered as part of good design from the start.
• Build independent infrastructure and controls that strengthen Jump's overall resilience.
• Support production and HPC-style compute workloads in the cloud, including provisioning, scaling, performance, and cost.
• Own a wide range of systems end to end, from networking and identity to compute, storage, and monitoring.
• Lead root cause analysis on incidents until the true cause is found and fixed.
• Improve monitoring, logging, and alerting so problems are detected and resolved quickly.
• Apply infrastructure security best practices, including access management, secrets management, server hardening, and audit logging.
• Pivot quickly to whatever needs fixing across the infrastructure, balancing competing priorities with minimal oversight.
• Work with a globally distributed team to maintain high availability.
• Other duties as assigned or needed.

Skills you’ll need:

• Broad, hands-on experience as an infrastructure generalist, such as Linux administration, DevOps, systems engineering, or SRE.
• Deep understanding of Linux internals and networking fundamentals, including TCP/IP, DNS, TLS, HTTP, routing, and load balancing.
• Strong experience with at least one major cloud provider (AWS, GCP, or Azure), including networking, IAM, and compute services.
• Working knowledge of infrastructure security fundamentals, such as IAM, secrets management, system hardening, and logging/audit.
• A proven track record of troubleshooting complex systems and driving root cause analysis across multiple layers of the stack.
• Experience designing and architecting systems, not just operating them.
• Experience with infrastructure-as-code and configuration management tools such as Terraform, Ansible, or Salt.
• Experience with monitoring and alerting tools such as Prometheus, Alertmanager, or Grafana.
• Proficiency in Bash and Python scripting. Deep software engineering experience is not required.
• Comfort working in a flat, fast-paced team.
• Reliable and predictable availability.

Bonus points:

• Exposure to HPC environments or large-scale compute clusters.
• Experience with Kubernetes and containerized workloads.
• Experience with bare-metal and hybrid infrastructure.
• Additional depth in security, such as incident response or secure architecture design.
• Experience in trading, financial services, or other high-availability environments.
