About the Role

• Drive architecture for scalability, reliability, security, and cost efficiency across distributed systems.
• Turn ambiguous problems into crisp designs, aligned execution plans, and high-quality shipped outcomes.
• Raise the engineering bar through design reviews, testing strategy, observability, and post-incident learning.
• Embed security, IAM, privacy, and governance into system design and delivery by default.
• Partner with squads across the firm to align on interfaces, ownership, and operational readiness.
• Improve delivery velocity with platform leverage, automation, and tooling—using AI responsibly to accelerate delivery and scale operations.

• 15+ years building and shipping production platforms at scale.
• Strong distributed systems and cloud-native experience (Kubernetes, CI/CD, reliability patterns).
• Proficiency in Python, Go, and/or Rust; strong fundamentals in code quality, testing, and performance.
• Deep experience with operational excellence: observability, incident response, and continuous improvement.
• Strong security fundamentals (IAM, data protection, governance) in production environments.
• Excellent collaborator and communicator across engineers, PMs, and executives.
• Ability to leverage AI to build, evolve, and maintain large-scale systems.

• Experience building developer platforms (internal tooling, control planes, APIs/SDKs/CLIs).
• Experience with SLOs/SLIs, capacity planning, and cost optimisation in high-availability services.
• Familiarity with Prometheus/Grafana/OpenTelemetry and modern reliability practices.
• Exposure to GenAI/LLM systems is a plus.
