• Work cross‑functionally with product, data, and business teams to deliver impactful solutions
• Oversee cloud infrastructure (AWS), ensuring security, cost efficiency, and resilience
• Implement robust monitoring, observability, and incident management frameworks
• Contribute hands‑on where needed across the stack (backend, infrastructure, data pipelines)

Requirements

• 5+ years' experience working with financial or quantitative datasets or Data Vendor Backgrounds.
• Proven experience in a DevOps / platform engineering environment, ideally within financial services or fintech
• Strong expertise in AWS and cloud‑native architecture
• Demonstrated experience in a technical leadership or team lead capacity
• Experience designing and operating scalable, distributed systems
