API Test Engineer

We''re looking for an experienced API Test Engineer to own service-level testing for our REST-based APIs — the backbone of mission-critical, bi-directional system integrations. You''ll design, execute, and automate test suites that ensure every endpoint is reliable, secure, and production-ready.

If you love turning complex technical requirements into airtight test scenarios and care deeply about what happens at the boundary between systems, this role is for you.

What you''ll test:
• Positive scenarios — valid inputs and expected responses
• Negative scenarios — invalid or missing data
• Boundary conditions — edge and limit cases
• Error handling — failures and unexpected inputs

Tools you''ll work with:
Postman · SoapUI · JMeter · Ping API · vREST

What you''ll need to know:
HTTP methods: GET, POST, PUT, DELETE
Status codes: 200, 201, 400, 401, 403, 404, 429, 500
Request/response headers and JSON request and response bodies.
