For people who love learning, innovating, and making an impact that matters now is the moment to be a part of Xapien. THE ROLE We're hiring a Senior DevOps Engineer to own our CI/CD platform and developer experience. You'll be the person who makes shipping software fast, safe, and enjoyable, building the foundations that every engineering team relies on daily. Our infrastructure runs on Kubernetes in GCP, with Go microservices, Temporal workflows, and a modern observability stack built on Grafana Cloud. You'll work across the full delivery pipeline, from how code gets built and tested, to how it gets deployed and monitored in production. We're an AI-native engineering team. We use Claude Code daily and we think seriously about how AI tooling changes the way engineering work gets done. We want a DevOps engineer who brings that same mindset to infrastructure and tooling, automating aggressively, reducing toil relentlessly, and thinking about how the right platform decisions multiply productivity across the whole org. You'll have real ownership here. This isn't a support role; you'll set the direction for how we build, test, and ship software, and you'll work closely with our platform and product engineering teams to make sure the developer experience keeps pace with our ambitions. WHAT YOU'LL DO * Own and evolve our CI/CD pipelines, making them faster, more reliable, and easier to reason about * Define and drive our developer experience strategy — from local development environments to deployment workflows * Build internal tooling and automation that reduces friction and cognitive load for product engineers * Establish standards and best practices around deployment, testing pipelines, and release processes * Partner with the platform team on the boundary between infrastructure and developer tooling * Instrument and improve the observability of our pipelines and delivery process * Champion a culture of fast feedback loops and high deployment confidence * Use AI tooling to accelerate your own work and help shape how the wider team does the same * Identify and address systemic bottlenecks in how we build and ship software * Mentor engineers across the org on DevOps practices and platform tooling WHAT WE'RE LOOKING FOR ESSENTIAL * 6+ years of professional experience in DevOps, platform engineering, or a related role * Strong hands-on experience with CI/CD platforms — GitHub Actions, ArgoCD, or similar * Deep understanding of Kubernetes and container-based deployment workflows * Experience with GCP or equivalent cloud provider at production scale * Solid infrastructure-as-code fundamentals (Terraform or similar) * Strong scripting and automation skills — comfortable in Bash, Python, or Go * A genuine interest in developer experience: you care about how engineers feel when they interact with the systems you build * Experience working with observability stacks — metrics, logs, traces — and using them to improve pipeline reliability * Ability to work autonomously and drive initiatives with minimal guidance * Strong communication skills — able to work across teams and translate infrastructure concerns into language that lands with product engineers HIGHLY DESIRABLE * Experience with Temporal or workflow orchestration systems * Familiarity with Kafka or event streaming infrastructure * Experience with Grafana, Prometheus, and the wider observability ecosystem * Background in platform or internal developer platform (IDP) thinking * Exposure to security and compliance tooling within CI/CD pipelines (SAST, SBOM, secret scanning) * Experience driving DevEx improvements and measuring their impact * Familiarity with AI-assisted development tooling and how it changes platform requirements OUR TECH STACK * Languages: Go, Bash, Python * CI/CD: GitHub Actions, ArgoCD * Infrastructure: Kubernetes, GCP, Terraform * Observability: Grafana stack (Prometheus, Loki, Tempo) * Messaging & Orchestration: Temporal, Kafka * Development Tools: Claude Code, AI-assisted development workflows WHAT SUCCESS LOOKS LIKE In your first 6 months, you will have: * Materially improved the speed or reliability of our CI/CD pipelines * Shipped at least one developer experience improvement that engineers talk about positively * Established clear ownership and standards around our deployment process * Built strong working relationships with platform and product engineering teams * Contributed to how we think about and measure developer productivity * Helped evolve our AI-assisted engineering practices within the DevOps domain Here’s our promise to you: * We are going to work with you - to build a rewarding and fulfilling career with the opportunities, challenges and resources you need to do you your best work. * We succeed together- you will own a meaningful part of the business through our employee shares & equity programme. * Private health insurance to keep you in tip-top condition. * Life Insurance – let's hope nobody ever needs this! * Unlimited holidays – yes, it really is uncapped – take the time you need, when you need it. * Everyone is learning, developing and challenging themselves so we have a £1k professional development fund per year if you want to learn new skills, even new things outside of work. * Most importantly of all, we will work with you, to help you realise your fullest potential, always.

Getting to "trust it with a £10bn decision" is the interesting part — and where you come in. THE WORK You'll own parts of the Xapien pipeline end-to-end — LLM research agents, entity resolution, report generation. Prototype, evaluate, ship, measure, improve. * Build a system optimised for accuracy, speed and cost * Design evals that measure what matters, driving meaningful improvements * Dig into the failures and fix them at the root * Shape and ship what's next - high ownership We use Claude Code by default and rarely write code ourselves. The craft is in careful prompting, tight loops, sharp evals, and spotting when the agent's quietly wrong. YOU * Fluent in Claude Code, Codex, or similar agentic tooling. * Strong numerical reasoning. Top-uni CS / maths / engineering / science, or equivalent in what you've built. * Shipped production LLM systems — RAG, prompting, agents. The kind customers pay for. * You've worked somewhere fast — startup or strong tech team — and make good calls on imperfect information. * You know software engineering: you’ve launched systems, responded to incidents, designed for failure * High-agency. You scope problems, own solutions, and help decide what we build next. * Focused on real answers for real customers. Theory's a tool, not the point. * Good to work with. Small team — it matters. Here’s our promise to you: * We are going to work with you - to build a rewarding and fulfilling career with the opportunities, challenges and resources you need to do you your best work. * We succeed together- you will own a meaningful part of the business through our employee shares & equity programme. * Private health insurance to keep you in tip-top condition. * Life Insurance – let's hope nobody ever needs this! * Unlimited holidays – yes, it really is uncapped – take the time you need, when you need it. * Everyone is learning, developing and challenging themselves so we have a £1k professional development fund per year if you want to learn new skills, even new things outside of work. * Most importantly of all, we will work with you, to help you realise your fullest potential, always.
