 Job Title: Support & Integration  Engineer

Location: Lagos What You'll Do

Production support and investigation Own the technical support queue: triage incoming issues, establish severity, and set expectations with the client Investigate failed, stuck, or missing transactions end to end — request logs, session traces, transaction records, provider calls, webhook deliveries — and produce a clear root cause Distinguish client integration errors from platform defects, and say so plainly with the evidence behind it Reproduce reported defects, isolate the cause, and hand engineering a report they can act on without re-investigating Validate fixes once shipped and close the loop with the client

Diagnose problems in clients’ existing API integrations — malformed requests, missed callbacks, incorrect retry handling, stale credentials Advise clients on correct API usage when their implementation is the cause, with specific examples rather than a link to the docs Keep API documentation and troubleshooting guides accurate as the platform changes, and correct them when a support ticket proves they were wrong

Translate client problems into engineering tickets with reproduction steps, impact, and affected records — and translate engineering answers back into language a client’s team can act on Escalate production incidents, coordinate the response, and keep affected clients updated Feed recurring issues back into the product — the same ticket arriving three times is a product problem, and you are the one who surfaces it Write and maintain internal runbooks so common issues stop requiring an engineer

Hands-on fixes:

Ship small backend fixes yourself — validation gaps, unclear error messages, misleading statuses, data corrections Write the regression test that proves the issue is actually fixed Improve internal tooling and admin surfaces that make investigation faster for the whole

Who You Are

Proficiency in NestJS and TypeScript; Go (Golang) is valuable Profound knowledge of MongoDB and Mongoose ODM, including writing your own queries and aggregations to investigate data; SQL and PostgreSQL are a major need Comfortable reading and debugging a large production codebase you did not write — the single most important skill in this role Able to design and consume RESTful APIs, and to explain them to a client’s developer in plain terms Proficient with unit testing frameworks, with a commitment to test-driven development and code reliability Strong knowledge of design patterns, and of implementing security and data protection measures Understanding of asynchronous programming and event-driven architecture — and of why a message can arrive twice, late, or out of order Experience with version control systems (e.g. Git), and the ability to write clean, maintainable code and take part in code review Comfortable in the terminal, with logs, and with API tooling
