Senior AWS Engineer/Platform Engineer |

Who we are We are a seed-stage AI start-up backed by leading European and US funds. Our founders previously built and deployed cutting-edge AI systems at world-class research labs and high-growth technology companies. We apply next-generation AI agents to transform mission-critical enterprise workflows that currently depend on brittle, manual processes. Our goal is to make these workflows safer, faster and far more resilient through thoughtful, responsible AI. You will design, build and run the cloud-native backbone that powers our AI agent workers at scale. Shape a multi-cloud platform (AWS first, Azure next) with infrastructure as code and GitOps, balancing speed, cost and security. Run high-throughput Kubernetes clusters (EKS), adding service mesh, policy enforcement and self-service tooling so product teams can ship confidently. Champion security and compliance, including secrets management, zero-trust networking, least-privilege IAM and audit trails ready for GDPR and SOC 2. Partner with AI and product engineers to shape runtime environments and data pipelines for large-scale model serving. Deep cloud mastery with AWS, including networking, IAM, storage and compute. Comfort with infrastructure as code, for example well-structured Terraform modules, policy as code and reusable patterns. Advocacy for CI/CD, building pipelines in GitHub Actions, GitLab CI or CircleCI with automated tests and security gates. A security-first but pragmatic approach, covering secrets management, image provenance and zero-trust networking. Proficiency in at least one systems language (Go, Python or Java) and familiarity with modern event-driven architectures. The ability to explain complex concepts in plain English to executives, customers and non-technical colleagues. Hybrid flexibility, with collaboration in person for the important work and remote working the rest of the time. Private healthcare, pension scheme and an annual off-site to disconnect and recharge.
