Our ability to compete depends on how quickly new ideas can move from insight to production. The Developer Experience team is a strategic engineering function with a clear mandate: improve the development lifecycle across the company in ways that accelerate delivery and reduce our time to market. We build the tools, systems, and platforms that shape how software is developed at Optiver.\nThe Build Platform sits at the heart of that lifecycle. Every change an engineer makes flows through it. When builds are fast, correct, and reproducible, engineers stay in flow, receive fast and trustworthy feedback, and shipping changes becomes routine. When builds are slow or unreliable, every team in the company pays the tax, one slow feedback loop at a time.\nWe’re looking for a strong engineer with a passion for improving developer productivity, a deep interest in build systems, and the experience to design and operate platforms at scale. You’ll join a growing global Developer Experience team and help shape the future of how software is built, tested, and delivered at Optiver, enabling both engineers and agents to move from idea to production-ready software with greater speed and confidence.\nWhat you’ll do\n\nShape the future of C++ builds at Optiver by designing and rolling out modern build systems that accelerate build times, improve reliability, and create a more consistent developer experience;\nDevelop common build libraries, reusable CI/CD pipelines, and container images used across the company;\nBuild observability into our platform so we can measure performance, reliability and adoption, and use that data to guide further improvements;\nImprove build performance at scale through incremental execution, caching, dependency analysis and efficient scheduling;\nDesign workflows that enable agents to compile, test, diagnose failures, and validate changes reliably with minimal human intervention;\nWork closely with engineering teams to understand where existing workflows create friction and turn those problems into scalable solutions;\nHelp teams adopt new tools and working practices, balancing standardisation with the needs of different codebases and engineering groups;\nStay current with industry trends and emerging tools in the developer experience and build systems space, helping guide our adoption of best-in-class solutions.\nSee the team lead's opinion on why DevEx matters here.\nWho you are\n\nYou are a strong software engineer with deep experience in C++ build systems and developer tooling;\nYou have hands-on experience designing, adopting, or operating modern build systems such as Bazel, Buck2, Pants, or Gradle, ideally including migration from established tooling;\nYou have a deep understanding of build system concepts including incremental builds, caching, reproducibility, dependency graphs, remote execution, and artifact management;\nYou are skilled at diagnosing performance and reliability issues across the local development and continuous integration lifecycle, using data and observability to guide improvements;\nYou have significant experience with CI/CD platforms such as GitHub Actions, Buildkite, Jenkins, or similar, and understand how to design reliable, scalable pipelines and the infrastructure that supports them;\nYou hold a deep understanding of the end-to-end lifecycle of software development from ideation to deployment;\nYou have experience building tools and workflows around source control platforms such as GitHub and GitLab;\nYou are passionate about developer productivity and have a track record of delivering meaningful improvements to the software development lifecycle.\nWho we are\nAt Optiver, our mission is to continuously improve the market. By providing liquidity and accurate pricing in various financial instruments, to multiple exchanges across the world, we participate in the safeguarding of healthy and efficient markets.\n\nWhat you’ll get\nYou’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Motivated by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle the toughest problems in the financial markets.\nIn addition, you’ll receive:\nA performance-based bonus structure, enabling all of our employees to benefit from our global profit pool.\n27 paid vacation days plus all UK public holidays.\nDaily breakfast and lunch, along with support on commuting expenses.\nPrivate medical insurance, pension scheme, and ClassPass fitness membership.\nTraining and continuous learning opportunities, including access to conferences and tech events.\nInternational transfer opportunities for global career growth.\nHow to apply:\nApply directly via the form below.
