Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Platform Engineer - **Company:** Lemfi - **Location:** UK - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Amazon Web Services, App Store (IOS), Continuous Integration, DevOps, Python (Programming Language), Scripting, Backend, Kubernetes, Google Play, Terraform - **Published:** September 5, 2026 - **Apply:** https://startup.jobs/senior-platform-engineer-lemfi-8779535 ## About the Role * Proven track record building an internal developer platform or developer experience function from scratch - not just maintaining one someone else built. * Deep AWS expertise: you have designed cost-efficient, production-grade cloud architectures and you can defend every line of your Terraform. * Strong DevOps and platform engineering fundamentals: Kubernetes, CI/CD, observability stacks, IaC, and the judgement to know when to use each. * Experience treating internal engineers as customers - gathering requirements, running a backlog, measuring adoption - not just shipping tools and hoping people use them. * Comfortable working without a spec: you have operated in fast-moving environments where you set the direction as much as you follow it. * Proficient in at least one scripting or backend language (Python, Go, or equivalent) and confident building automation and tooling, not just configuring managed services. * You actively build AI-powered tooling into platform and infrastructure workflows - cost anomaly detection, intelligent alerting, automated runbooks - not just use AI in your editor., * Previous fintech or regulated-industry experience where security and compliance constraints shaped your platform decisions. * Hands-on experience with platform engineering frameworks such as Backstage or Port, or building a comparable internal portal. * Exposure to multi-region or multi-currency infrastructure at scale, ideally serving markets in Africa, Europe or the Americas. ## Description * Design and build a self-service internal developer platform - golden paths, templates, guardrails - so engineers can provision, deploy and operate services without raising a ticket. * Embed AI-driven automation into the platform: intelligent cost optimisation, anomaly detection, auto-remediation and developer productivity tooling that actually gets used. * Own cloud infrastructure on AWS - architecture, cost efficiency, reliability and security posture - with clear metrics and accountability for outcomes, not just uptime. * Act as the internal product manager for the platform: talk to engineers regularly, collect requirements, prioritise by impact on developer velocity and run a visible roadmap. * Set and enforce platform standards - IaC, CI/CD pipelines, observability, secrets management - turning good practice into the default, not the exception. * Identify and fix the biggest sources of friction in the engineering workflow, using data to prioritise and presenting findings to engineering leadership. * Work lean and autonomously: this is a high-ownership role on a small team, so you will need to push things to production yourself, not coordinate others to do it. ## Related Videos - [Platform Engineering vs. DevOps Why not both?](https://www.wearedevelopers.com/videos/885-platform-engineering-vs-devops-why-not-both) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [JavaScript?
