Senior Platform Engineer (Agentic Experience)

You will report to the Director of Engineering and sit within a Platform Engineering team of around eight people, working alongside Platform, Data, and AI Engineers. The problems here are rarely well-defined upfront - this role is for someone who identifies what needs solving, not someone who waits for a Jira ticket., * Build a developer productivity measurement platform integrating GitHub, Linear, Slack, and CI/CD signals into a coherent view of delivery flow

• Identify and remove friction from engineering workflows: slow pipelines, poor feedback loops, unclear ownership, and noisy alerting
• Define, deploy, and iterate on AI tooling for local development, including IDE integrations, agentic tools, MCP servers, and model integrations such as Claude and Codex
• Build the guardrails that make AI adoption safe: prompt logging, data classification boundaries, an approved model catalogue, and usage observability
• Understand the workflows of engineering and product teams to surface bottlenecks, systemic issues, and drive improvements with their buy-in.
• Maintain Kubernetes and microservices credibility across the platform - this is an engineering role, not programme management.
• Write documentation that engineers actually use: runbooks, adoption guides, and decision records

Do you have experience in Microservices?, * 8+ years of experience in cloud-native startups, FinTechs, or high-volume engineering environments

• 3+ years working in a team focused on developer experience
• 1-2 years using modern agentic tools in a professional setting
• 3+ years of hands-on Kubernetes experience or managing Cloud infrastructure.
• 5+ years working with microservices architecture

• Able to identify what needs solving, not just execute what has been scoped
• Brings rigour to fast-moving tooling decisions, weighing productivity gains against security and compliance constraints in a regulated environment
• Builds trust with engineering teams through hands-on presence, not top-down mandates
