Their teams are composed of passionate problem-solvers who operate in a dynamic, large-scale IT environment. We are seeking a visionary engineer to lead critical reliability and automation initiatives, ensuring the firm's complex trading and research platforms operate with maximum performance, scalability, and resilience.
The Role:
We are seeking a deeply experienced Site Reliability Engineer to act as a Tech Lead for key infrastructure initiatives. This is a crucial, hands-on role for a hybrid systems and software engineer who thrives on solving complex problems at scale.

Responsibilities:

• Lead the design and execution of high-impact projects focused on improving the reliability, scalability, and performance of their core infrastructure.
• Architect, build, and maintain mission-critical tools and automation in Python or Go to eliminate operational toil and enhance system capabilities.
• Serve as a senior escalation point for complex Linux systems issues, diagnosing and resolving deep technical challenges related to performance, configuration, and stability.
• Drive the architecture for scalable, resilient, and performant infrastructure, making key design decisions for production environments.
• Mentor and guide other engineers, championing best practices in software development, infrastructure management and site reliability.

• 7+ years of experience in a senior site reliability, infrastructure, or software engineering role with a track record of success in complex, large-scale environments.
• Expert-level proficiency in Python or Go, with a proven track record of engineering libraries, tools, or applications (not just scripting).
• Deep, hands-on expertise with the Linux operating system, including performance tuning, troubleshooting, and systems administration in a large-scale environment.
• Demonstrated experience leading technical projects, driving architectural decisions, and mentoring other engineers.
• Strong knowledge of CI/CD, infrastructure-as-code (Ansible, Terraform), and containerization (Docker, Kubernetes).
• Exceptional communication skills, with the ability to articulate complex technical concepts to a variety of audiences.
