API Engineer

Role overview Build and evolve a shared API platform that lets multiple products and services securely use common business logic, data, and analytical capabilities. The work spans backend engineering, platform design, and collaboration with product and application teams, with an emphasis on creating reusable services rather than isolated integrations.

Responsibilities - Design and maintain APIs used by multiple applications and types of consumers. - Develop reusable platform services for business logic, data access, and analytics. - Define authentication, authorization, access controls, and trust boundaries for different consumers. - Establish practical standards for API contracts, errors, versioning, reliability, performance, and security. - Monitor and troubleshoot production services, improving their performance and maintainability. - Work with product and application teams to shape shared capabilities, including support for emerging AI use cases.

Requirements - Three to five years building production APIs and backend services. - Strong experience in a modern backend language such as Python or TypeScript. - Understanding of API design, including REST or GraphQL, and experience with production authentication and authorization. - Experience building services used across multiple applications, teams, or consumer types. - Strong SQL skills, data modeling knowledge, and a sound grasp of application and API security. - Ability to work across application, data, and platform concerns, assess trade-offs, and explain decisions clearly. - Familiarity with modern data access, API, or semantic-layer technologies.

Nice to have - Experience with internal platforms, identity and access management, or fine-grained authorization models. - Exposure to analytical or semantic data layers, AI-oriented data access, cloud infrastructure, CI/CD, or observability.
