Staff Software Engineer (API Development)

Overview One Identity 's OneLogin team is seeking Senior Software Engineer s who operate with high ownership, strong technical judgment, and a bias for action. These roles are designed for engineers who identify and solve problems proactively — not just execute assigned work. Senior Engineers at OneLogin are expected to operate as T-shaped engineers: deep in a primary domain while remaining capable across the stack (backend, APIs, cloud, and operations). You will play a key role in maintaining product velocity, improving system reliability, and reducing operational burden. This is a hands-on role that includes on-call responsibilities and requires a strong commitment to modern engineering practices, including AI-augmented development. We are looking for engineers who take full ownership — design, build, test, deploy, and operate — rather than handing work off between silos. In this role, you will focus on standardizing API development through tooling and automation, improving consistency, usability, and integration velocity across services. You will leverage AI-powered tools to accelerate API design, validation, and standardization — improving developer workflows and reducing inconsistency at scale. Responsibilities Standardize API development through tooling and automation so the right approach is the default • Define and evolve API standards (OpenAPI), and enforce through tooling, automation, and CI/CD workflows (not manual review processes) • Build and maintain systems that auto-generate, validate, and enforce API specifications (contracts, schemas, validation) • Integrate AI into API development workflows to improve specification quality, consistency enforcement, and documentation accuracy • Reduce bespoke implementations by providing shared patterns, libraries, and templates for API development • Improve API consistency, discoverability, and usability across services • Enable faster internal and partner integrations through well-defined, reliable, and documente
