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
