Senior Systems Engineer

WorldQuant develops and deploys systematic financial strategies across a broad range of asset classes and global markets. We seek to produce high-quality predictive signals (alphas) through our proprietary research platform to employ financial strategies focused on market inefficiencies. Our teams work collaboratively to drive the production of alphas and financial strategies – the foundation of a balanced, global investment platform.

WorldQuant is built on a culture that pairs academic sensibility with accountability for results. Employees are encouraged to think openly about problems, balancing intellectualism and practicality. Excellent ideas come from anyone, anywhere. Employees are encouraged to challenge conventional thinking and possess an attitude of continuous improvement.

Our goal is to hire the best and the brightest. We value intellectual horsepower first and foremost, and people who demonstrate an outstanding talent. There is no roadmap to future success, so we need people who can help us build it.

The Role: We are seeking a Senior Systems Engineer to join a team that operates and evolves a complex distributed architecture spanning physical machines, Kubernetes and cloud computing environments. You will be part of a high-impact team championing operational excellence, reliability, and performance.

The role involves:

• Working across multiple layers of the stack,
• Participating in our on-call system as part of a shared rotation,
• Collaborating closely with developers,
• Mentoring and supporting junior support staff,
• Helping integrate AI-driven solutions into our systems.

What you'll bring:

• Strong Linux system internals, performance tuning, and troubleshooting skills.
  
• Solid networking knowledge and ability to debug complex connectivity issues.
  
• Hands-on experience with complex distributed systems (e.g., Kubernetes, Kafka, Kerberos).
  
• Practical experience with CI/CD tools and modern SDLC practices.
  
• Proficiency with containers and virtualization (Docker, Kubernetes, or similar).
  
• Experience with observability/telemetry.
  
• Strong scripting/automation skills (ideally Python).
  
• Ability to collaborate with developers and help integrate AI solutions into production systems.
