Lead the design, implementation, and long-term evolution of libraries and SDKs used by large-scale, production services. Apply systems programming principles-safety, performance, reliability-with a strong focus on Rust and fit-for-purpose abstractions. Drive API design with attention to developer ergonomics, compatibility, versioning strategy, and adoption across multiple teams. Partner with service teams to translate requirements into shared components; influence integration patterns and reduce friction for adoption. Establish or raise engineering quality bars through testing strategies, documentation, sample usage, CI validation, and release practices. Mentor engineers through design reviews, code reviews, and technical coaching; contribute to improving the team's engineering foundation. Bachelor's Degree in Computer Science or related technical field AND technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python Experience delivering production-quality software and leading implementation across feature areas. Experience designing, building, or maintaining shared libraries/frameworks/SDKs with attention to API contracts, testing, and lifecycle management. Demonstrated technical leadership (e.g., driving design reviews, guiding architecture decisions, improving engineering practices). These requirements include but are not limited to the following specialized security screenings: Master's Degree in Computer Science or related technical field AND technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR Bachelor's Degree in Computer Science or related technical field AND technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. Experience with Rust in production or building reusable systems/infrastructure components in Rust. Experience with large-scale services or distributed systems and understanding of reliability/performance tradeoffs. Experience establishing patterns for adoption (docs, samples, migration guidance, compatibility strategy) across multiple teams. Track record of cross-team collaboration, including navigating tradeoffs and aligning with partner needs.
