Software Engineer - Build Platform

In this role you will shape the future of C++ builds at Optiver by designing and rolling out modern build systems to speed up builds, improve reliability, and standardize developer experience. You will develop reusable build libraries, CI/CD pipelines, and container images used company-wide. You will embed observability to measure performance and guide improvements, and optimize builds at scale with caching and incremental execution. You will collaborate with engineering teams to remove friction and help agents compile, test, and validate changes with minimal manual intervention. This is a chance to influence how software is built and delivered at Optiver, supporting faster, more confident—d
