This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Data API Engineer based in Spain.

We are seeking a skilled software engineer to help enhance the performance, reliability, and capabilities of a PostgreSQL-powered Data API used by developers worldwide. In this role, you will contribute to the development of PostgREST, working on database connectivity, query performance, new features, and a roadmap toward a more scalable, multitenant API. You will investigate complex technical issues, eliminate performance bottlenecks, and strengthen observability to improve service reliability. Working closely with cross-functional engineering teams, you will help resolve integration challenges and deliver a seamless developer experience. This opportunity is ideal for an engineer with strong Haskell expertise, a passion for PostgreSQL, and a commitment to open-source software. You will join a globally distributed, asynchronous team that values technical ownership, open collaboration, and building dependable developer tools at scale.

Accountabilities

• Improve database connectivity: Work on the PostgreSQL driver used by PostgREST, built on Hasql, identifying bottlenecks and implementing optimizations to improve performance and efficiency.
• Develop Data API capabilities: Contribute to PostgREST development by implementing new features, resolving bugs, and advancing the platform toward a scalable, multitenant Data API.
• Enhance reliability and performance: Investigate service issues, diagnose root causes, and implement improvements that strengthen API stability, responsiveness, and overall performance.
• Strengthen observability: Improve monitoring and diagnostic capabilities to make it easier to identify, investigate, and resolve operational issues.
• Handle technical incidents: Resolve incidents and escalated support requests, ensuring technical problems are addressed effectively and recurring issues are reduced.
• Collaborate across engineering teams: Work with other teams to troubleshoot and resolve integration issues involving the broader platform and its services.
• Support developers and users: Help users overcome technical challenges by investigating reported problems and communicating solutions clearly to people with varying levels of technical expertise.
• Contribute to open source: Participate in the development and improvement of open-source software, collaborating with the community to strengthen shared tools and infrastructure.
• Drive continuous improvement: Identify opportunities to improve code quality, system architecture, debugging workflows, and the overall developer experience.

Requirements

• At least 3 years of professional experience with Haskell, with strong proficiency in the language and its practical application to software development.
• Experience using the C programming language and the ability to work with systems-level code when needed.
• Strong knowledge of SQL and PostgreSQL, including experience writing and working with PL/pgSQL scripts.
• Experience debugging applications in Linux environments, with the ability to investigate complex technical problems and identify root causes.
• A strong track record of contributing to open-source projects; experience maintaining an open-source project is an advantage.
• Experience providing technical support to users with different levels of technical knowledge, including diagnosing issues and explaining solutions clearly.
• Strong analytical and problem-solving skills, with the ability to investigate performance bottlenecks and improve the reliability of complex systems.
• Ability to collaborate effectively with cross-functional engineering teams and contribute to shared technical objectives.
• A proactive, ownership-oriented mindset, with the ability to work independently and manage tasks in an asynchronous environment.
• Enthusiasm for open-source development, developer tooling, and building reliable, high-performance APIs.
