API Architect

We are seeking an experienced API Architect who will serve as the technical point of reference in the organization, setting the vision, principles, and best practices for API design and governance. Your mission will be to ensure consistency, high quality, and scalability of our platform.

Key responsibilities

• Define architecture strategy and standards for REST, gRPC, GraphQL, versioning, security (OAuth 2.0 / OIDC), observability, and SLAs.

• Create style guides, templates, and linters that enable consistent microservice development.

• Advise product and engineering teams throughout the API life-cycle: discovery, API-first design, reviews, deployment, and deprecation.

• Lead design-review boards (ADRs) and architecture committees.

• Evangelize best practices through workshops, living documentation, and pair-design sessions.

• Select and govern the API-management platform (Kong, Apigee, AWS API Gateway, etc.) and contract tooling (OpenAPI / Swagger).

• Define success metrics and dashboards for API quality, reliability, and usage.

• Research trends (AsyncAPI, API monetization, event-driven patterns) and translate them into technical roadmaps.

Technical requirements

• 8+ years designing and building large-scale APIs; 3+ years as an architect or tech lead.

• Expert in contract-first design with OpenAPI 3.x and JSON Schema.

• Proficient in Python, Java, and Go (able to read, review, and propose patterns in all three).

• Deep knowledge of microservices, Kubernetes, and service meshes (Istio / Linkerd).

• Experience with Git-based CI/CD, contract testing (Prism, Dredd), and load testing (k6, Gatling).
