Lead DevOps Engineer - AI, AWS, Python, Terraform - £100,000 - £120,000
A dynamic and forward-thinking technology company at the forefront of autonomous AI agent development is seeking a talented and experienced Lead DevOps Engineer. This is a pivotal role focused on the core infrastructure that powers their innovative AI platform.
This is an exciting opportunity for a Lead DevOps Engineer to take ownership of and significantly enhance the compute layer that underpins their groundbreaking technology. You will lead the migration of their current system to a more scalable and customizable container-based architecture, directly impacting the performance, reliability, and cost-efficiency of their core offering. You will be instrumental in building the foundational elements that enable their AI agents to operate seamlessly and efficiently.
The ideal Lead DevOps Engineer will be responsible for:
* Architecting and executing a zero-downtime migration to AWS Fargate (ECS) from AWS App Runner.
* Developing a unified observability framework encompassing tracing, structured logging, and metrics that seamlessly track requests across the entire lifecycle, from API Gateway through the runtime engine and sandboxed environments to external APIs, visualized in tools like Grafana, Loki, or Prometheus.
* Building intuitive self-service tools for internal developers, such as CLI tools, GitHub Actions, and Backstage plugins, enabling them to quickly provision new micro-services or AI agents (in under 5 minutes) with built-in security, secrets management, testing frameworks, and cost controls.
* Ensuring robust security and compliance through hard multi-tenant isolation of sandboxed environments, implementing least-privilege IAM principles, establishing secret-less CI/CD pipelines, and generating auditable Software Bill of Materials (SBOMs) to meet SOC 2 and GDPR requirements.
The ideal Lead DevOps Engineer will have experience with the following:
* Deep and practical knowledge of AWS services.
* A strong product-centric approach to infrastructure, with a genuine empathy for internal developers and a passion for designing developer experiences that are both powerful and easy to use.
* A data-driven mindset focused on measured performance, including experience tuning cold-start times, optimizing container resource allocation (CPU/Memory), and utilizing cost data to identify and eliminate waste.
* A passion for automation, with hands-on experience using tools like Terraform/CloudFormation/CDK, GitHub Actions, and implementing CI/CD pipelines, canary deployments, and policy-as-code.
* Proficiency in at least one of Python, Go, or TypeScript.
* An intellectual curiosity about Artificial Intelligence and a basic understanding of how Large Language Models (LLMs) interact with tools, track token usage, and require low-latency backend infrastructure.
* A pragmatic approach and comfort working in a fast-paced, ambiguous startup environment where delivering results is prioritized.
This is a unique opportunity to be a key technical leader in a well-funded and rapidly growing company that is pioneering the future of autonomous AI agents. If you are a highly skilled and motivated platform engineer ready to build and scale the critical infrastructure that powers cutting-edge AI technology, we encourage you to apply!
