Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Platform Engineer - **Company:** StackOne - **Location:** London, UK (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Amazon Web Services, Amazon Cloudfront, Amazon S3, Microsoft Azure, Cloud Computing, Continuous Integration, DevOps, Programming Tools, Github, Identity and Access Management, Python (Programming Language), PostgreSQL, Node.Js, Redis, Runbook, Test Execution Engine, TypeScript, YAML, Datadog, AWS Cdk, Amazon ElastiCache, Delivery Pipeline, Large Language Models, Multi-Cloud, Kubernetes, Sentry, Cloudflare, AWS Fargate, Apache Kafka, Vertica, Terraform, Workday, Docker - **Published:** June 2, 2026 - **Apply:** https://uk.indeed.com/viewjob?jk=4aa977644597a7b0 ## About the Role Do you have experience in Workday?, * 4+ years in platform, infrastructure, SRE, or DevOps, with hands-on AWS at scale: ECS/Fargate, RDS/Aurora, Lambda, networking, IAM, KMS. * Deep IaC ability: Terraform and/or AWS CDK, comfortable owning modules and patterns other teams build on. * Strong CI/CD and monorepo build experience: caching and incremental/affected-only test execution. You've made a slow pipeline fast. * Strong coding ability in TypeScript, Python, or Go. You build tooling, not just YAML and configs. * Containers in production (Docker); Kubernetes a plus. * Security-minded: you bake secure defaults into pipelines and repo templates and enjoy partnering with security rather than routing around it. * A clear writer: you produce docs and runbooks that both internal engineers and external customers can follow. * You own work end-to-end (scope, ship, measure) and automate instead of running manual checklists. * (Preferred) Experience shipping software into customers' own cloud or on-prem (BYOC / self-hosted distribution), or with a platform like Nuon, Replicated, or Omnistrate. * (Preferred) Multi-cloud (GCP or Azure) IaC, and exposure to Temporal, Kafka/MSK, ClickHouse, or OpenSearch. ## Description We're looking for a Senior Platform Engineer to own how StackOne is built, shipped, and run, as we scale across our own cloud and into our customers' clouds. You'll own the infrastructure behind the platform, our deployment pipeline and developer tooling, and how we package StackOne to run inside customers' own AWS, GCP, or Azure accounts. It's a hands-on role with broad scope. You write code and tooling, you own the IaC other engineers depend on, and you set the standard for how every new repository gets deployed and secured. You'll report directly to the CTO and work closely with our Security Engineer and tech leads., * Own our infrastructure at scale: the AWS estate today (ECS Fargate, Aurora, ElastiCache, MSK, OpenSearch, Lambda, KMS) and the AWS CDK to Terraform migration. Keep it reliable, observable, and cost-aware. * Build out our deployment pipeline and test tooling as we consolidate toward a monorepo: the CI/CD that ships every service, plus an automated end-to-end testing harness with incremental (affected-only) testing that stays fast as we grow. * Own how we deploy into customers' own clouds (self-hosted / BYOC): the Terraform modules, container images, runbooks, and documentation for both internal teams and customers. * Build the release and upgrade path for self-hosted customers: versioned, signed releases, a supported-version policy, and a call-home for usage and version reporting. * Set the standard for new repositories: partner with the Security Engineer and tech leads to define how new projects (customer-facing product, internal tools, and vibe-coded prototypes alike) get deployed and secured from day one. Templates, golden paths, and guardrails, not gatekeeping. * Raise reliability: SLOs, observability, and incident response for the platform. Make the system easy to operate when something breaks at 3am. * Treat infrastructure as a product: paved roads and self-serve tooling so product engineers ship without waiting on you. * Use LLMs and agents to accelerate platform work (IaC generation, test scaffolding, runbook drafting) with guardrails you trust., * Cloud & infra: AWS (ECS Fargate, Aurora Postgres, ElastiCache, MSK, OpenSearch, Lambda, S3, KMS, CloudFront, WAF), Cloudflare (Workers, WAF) * IaC: AWS CDK today, migrating to Terraform * Data & messaging: Postgres, Redis, Kafka, OpenSearch, ClickHouse * CI/CD: GitHub Actions * Observability & analytics: Datadog, Sentry, Metabase * Languages: TypeScript (Node.js), Python ## Related Videos - [CI/CD with Github Actions](https://www.wearedevelopers.com/videos/856-ci-cd-with-github-actions) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Empowering Thousands of Developers: Our Journey to an Internal Developer Platform](https://www.wearedevelopers.com/videos/1519-empowering-thousands-of-developers-our-journey-to-an-internal-developer-platform) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Platform Engineering vs. DevOps Why not both?](https://www.wearedevelopers.com/videos/885-platform-engineering-vs-devops-why-not-both) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
