Senior Fullstack Engineer (Backend Lean)

Location: Lagos, Nigeria (remote) Type: Full-time Team: Engineering About Ezrah

Ezrah is a decentralised identity and verifiable data infrastructure company. We apply cryptographic signatures to events, activities, and data records so any party can verify authenticity, without relying on a trusted intermediary. Our products span credential issuance, compliance tooling, financial data integrity, and identity verification, built on Polygon. We're a small, high-output engineering team. Everyone owns real surface area from day one. The role

We're looking for a senior fullstack engineer with a backend-first instinct. You're most at home designing systems — APIs, data models, queue workers, service boundaries — but you can cross into the frontend when the work demands it. You'll be a primary builder on the ERP system, compliance tracking platform, and core API infrastructure that powers everything Ezrah runs.

You'll work from tickets and defined tasks, but we expect more than execution. The right person flags design gaps before they become bugs and takes ownership of their surface area — not just the line of code they were assigned. What you'll own

Design and build backend services in NestJS — REST and GraphQL APIs, business logic, service architecture

Own and evolve the data layer using Prisma and PostgreSQL — schema design, migrations, query optimisation

Build and maintain BullMQ job queues and background workers for async workflows

Implement core modules of the ERP system end-to-end — from data model to API contract

Build the compliance tracking backend — audit trails, controls, reporting pipelines

Contribute to frontend work in Vue when required — dashboards, internal tools, data views

Participate in technical design sessions and API contract decisions with the CTO What we're looking for

Must have

5+ years of professional Node.js backend development

Strong, production-tested NestJS experience — modules, guards, interceptors, dependency injection

Deep Prisma experience — schema design, migrations, complex queries, relation handling

PostgreSQL fluency — schema optimisation, indexing, transactions

Experience with job queue systems — BullMQ, Bull, or equivalent

TypeScript as your default — no exceptions

REST and GraphQL API design experience at production scale Strong plus:

Experience with Docker and containerised deployments

Exposure to financial or compliance systems — audit trails, data integrity, access control

Familiarity with Go or other strongly typed backend languages

Understanding of event-driven architecture patterns

What we're not looking for

Engineers who treat backend as the only thing that matters — you need to be able to ship a dashboard when the work calls for it

Someone who needs close supervision to unblock themselves

Engineers without TypeScript depth — this is non-negotiable at Ezrah What you'll get

Direct collaboration with the CTO on architecture and system design

Real ownership — you'll be the primary builder on systems that matter

Competitive salary commensurate with experience A fast-moving codebase where your work ships and has visible impact How to apply
