We are looking for the very Top Talentand we would be delighted if you were to join our team More in details UST is a multinational company based in North America certified as a Top Employer company with over 35. 000 employees all over the world and presence in more than 30 countries. We are leaders on digital technology services and we provide large-scale technologic solutions to big companies. What are we looking for Were looking for a Senior DevSecOps Engineer for a 100 remote position with a leading UK financial services client. Strong experience in TDD/BDD DevSecOps CI/CD Infrastructure as Code and observability is essential. Were seeking an AI-first mindset with experience or interest in GitHub Copilot Claude and agentic AI. Experience with C# Python TypeScript Terraform AWS Azure GitHub or Azure DevOps would be a plus. The mission Drop into a fast-paced AI-first cross-functional team and contribute by building ideating and experimenting. We believe first-class management of a developer toolchain will be automated through AI and we intend to be the team that proves it. From that foundation we build the next generation of products that lift the productivity security and quality of every team in the organisation. Stated plainly we are building the best Developer Platform Product team in the industry and we are hiring the people who will do it. What you will do Build. Working software on a real estate in front of real engineers fast. Prototypes that earn their place and then get hardened not documents that describe what we might do. Put agents to work on the toolchain. Remediation at fleet scale pipeline upgrades across thousands of repositories and increasing at new pace scanner triage credential rotation the slow manual work that should not be manual. If an agent can do it build the agent. Design how autonomous things are allowed to act here. Identity scoping blast radius audit trail stop button prompt injection. An agent holding a token on a regulated estate is a security design problem and in this team the person building it is the person who solves it. Create new products on our own platform. Self-serve dashboards MCP servers skills developer tooling. Chosen on what customers actually do rather than on what we assume they want. Ship defaults not guidance. We shift left by making the safe correct path the default in the pipeline people already use. We do not ask developers to do more earlier. Experiment with discipline. Trials are capped and time-boxed with a decide-or-kill date and a written verdict either way. The discipline is in the killing not the trialling. Work test-first including on the things people usually do not test. Pipelines infrastructure and agents whose output is different every time. Ephemeral environments and contract tests over the golden path not a plan-diff and a hopeful merge. Continuous Delivery Practices Follow continuous delivery practices across all code platforms and products. Make the estate observable. Monitoring telemetry logging tracing and ing across our platform and our pipelines. This is an open area for us today and one of the clearest places to make a mark early because nothing else here works without it agents cannot be trusted with work we cannot see and delivery metrics we cannot measure are opinions. Talk to customers yourself. Sit with delivery teams watch what actually happens and bring findings back that change the roadmap. Help run what we own. Everyone here can keep the platform running and we operate our own platform the way we ask our customers to operate theirs zero-downtime defined in code tested before it ships. What good looks like Early on you are shipping. Something small real and in production plus a clear read on where the manual effort in this estate actually goes. By six months an agentic flow of your design is doing work that a person used to do with numbers behind it what it fixed how often it was wrong what it cost. And a second idea in trial. Our own four delivery measures are known rather than guessed at with a stated target for each and at least one of them moving. By twelve months at least two other engineers can run debug and extend what you built without you in the path and you are onto the next thing. Nothing we operate rests on one person and that rule applies to your own work from the day you build it. What we look for Essential TDD and BDD practised to a high level. Not unit tests written afterwards. Test-first as your default working mode on production code you were accountable for sustained under delivery pressure rather than abandoned the first time a date got tight. You believe in these practices and you can apply them in an agent-first context where the output is different on every run. A deep understanding of true DevSecOps. Teams own their pipelines and treat them like their applications and their code. Security is part of building not a gate at the end of it. Trunk-based development. Short-lived branches continuously integrated rather than long-lived branches and a painful merge. Pairing. It is how we work and how capability spreads not something we do when there happens to be slack. Infrastructure as code. Everything we run is defined in code and reviewed and tested as code. Measure do not assume. Observability as a first-class capability. Real experience of monitoring telemetry logging tracing and ing and the judgement to know which signals are worth paying for. You instrument your own work by default rather than waiting for an incident to tell you what you should have been watching. Delivery metrics driven to the elite DORA band. Release on demand lead time and time to restore service inside the hour change failure rate in the low single digits. You have carried a team or a platform toward numbers like those and you know the difference between improving the metric and improving the system that produces it. AI-first and already on the journey. We use Claude and GitHub Copilot alongside a growing fleet of cloud agentic tools to do our work and we are deep in the practice of working out what engineering looks like in an AI-first world. You are on that journey now and keen to keep exploring it at pace. Experience and interest rather than mastery CI/CD platforms patterns and practices. Some real experience and genuine interest in where they are going next.
