You'll work on improving the "user interface" of the build system by defining ergonomic yet powerful ways to express project configuration. You'll find ways to combine our unique problem domain with established techniques to provide user friendly experiences while maintaining high performance and scalability. You'll analyze problem requirements, existing solutions, and available systems and make high-level architectural decisions about how to architect various layers of the build system stack, considering both short- and long-term goals. Once solutions are identified, you will work alongside our team and numerous partner teams to implement them while developing appropriate testing and operational mechanisms. You will participate in the Swift Open Source project and engage with the developer community to collaboratively evolve our product.You will be most successful here as a flexible and proactive engineer who thrives in a supportive, respectful, and balanced work environment with interesting and challenging problems to tackle. You have excellent judgment and integrity with the ability to make timely and sound decisions. You know how to drive constructive discussion of design points, learn from your team, and use your experience to advocate and teach others.
