We're looking for a Senior Software Engineer to design, build, and evolve our enterprise data APIs. This role will be actively involved in API architecture and delivery, contribute to a new API catalog and self-service discovery portal, and help drive AI-assisted improvements to how we design, build, and ship APIs.
We're looking for someone who combines strong hands-on engineering with the judgment to architect scalable, secure, well-documented APIs - and who's comfortable coordinating across teams to get there.
Essential Functions:- Design, build, and maintain APIs using .NET.
- Architect API and database solutions for scalability, reliability, and maintainability.
- Design, optimize and integrate databases - MongoDB, PostgreSQL, MySQL, and OpenSearch - with APIs for efficient data storage, search, and retrieval.
- Use Kafka for event-driven and streaming integration patterns.
- Author and maintain API specifications using OpenAPI, ensuring consistent, well-documented API design standards.
- Contribute to a formal API catalog and registry - a developer portal where teams can discover available API endpoints through natural-language search.
- Help drive AI-assisted improvements to API development and delivery (e.g., AI-assisted code generation, testing, or monitoring).
- Debug and troubleshoot production issues using Grafana and related observability tooling.
- Identify and remediate security vulnerabilities using SonarQube (SAST), DAST tooling, and OWASP Top 10 best practices.
- Participate in requirement analysis, estimation, and deliverable planning in coordination with cross-functional teams.
