Software Engineer - Build Platform

At Optiver, the velocity of our software development is a critical part of our competitive advantage. 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  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.

We’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 ’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.

What you’ll do Shape 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;

Develop common build libraries, reusable CI/CD pipelines, and container images used across the company;

Build observability into our platform so we can measure performance, reliability and adoption, and use that data to guide further improvements;

Improve build performance at scale through incremental execution, caching, dependency analysis and efficient scheduling;

Design workflows that enable agents to compile, test, diagnose failures, and validate changes reliably with minimal human intervention;

Work closely with engineering teams to understand where existing workflows create friction and turn those problems into scalable solutions;

Help teams adopt new tools and working practices, balancing standardisation with the needs of different codebases and engineering groups;

Stay current with industry trends and emerging tools in the developer experience and build systems space, helping guide our adoption of best-in-class solutions.
