Required:

- Bachelor's degree in Computer Science (or Computer Engineering).

- Minimum 5 years of hands-on backend engineering experience, including clear ownership of

production systems.

- Deep expertise in Node.js and its ecosystem: Express.js or NestJS, npm, and modern

JavaScript (ES2020+). Strong TypeScript experience is expected.

- Solid understanding of Node.js internals and their practical implications: the event loop,

async patterns, memory management, worker threads, clustering, and how to avoid blocking

operations in high-throughput flows.

- Strong command of relational databases (PostgreSQL/MySQL): schema design, indexing,

transactions, isolation levels, and query optimization. Practical experience with an ORM or

query builder (Prisma, TypeORM, Sequelize, Knex) plus the ability to write and tune raw SQL.

- Proven experience designing and building secure REST APIs consumed by mobile clients,

including versioning, pagination, error contracts, and idempotency for financial operations.

- Solid application security background: OWASP Top 10, secure authentication and session

management (JWT, refresh token rotation), authorization models, secrets management,

encryption at rest and in transit, and dependency and supply-chain security (npm audit,

lockfile discipline).

- Experience with systems where data integrity is critical — financial, payments, ledger,

billing, or transactional platforms.

- Automated testing discipline in the Node.js ecosystem (Jest, Vitest, Supertest) covering

unit, integration, and API-level tests.

- Practical experience with Docker, CI/CD pipelines, and cloud infrastructure (AWS or similar).

- Strong debugging and production troubleshooting skills, including profiling Node.js

performance issues and memory leaks, and on-call ownership of live incidents.

- Ability to work independently, make sound architectural decisions, and be fully accountable

for outcomes.

- Good written and spoken English.

Preferred:

- Prior experience in fintech, banking, payments, trading, or commodities.

- Experience integrating with ERP systems, identity verification providers, or payment

gateways.

- Experience with real-time or near-real-time pricing and market data flows (WebSockets,

Socket.IO, or Server-Sent Events).

- Experience with caching and job/queue processing in Node.js (Redis, BullMQ, RabbitMQ, or

Kafka) and event-driven design.

- Experience leading or mentoring engineers, or being the senior-most backend engineer on a

product.

- Familiarity with monorepo tooling and shared-package management for multi-service Node.js

codebases.

What we are not looking for:

- Someone who needs a fully defined ticket to start working.

- Someone who has only worked as one contributor inside a large team without ever owning a

system end to end.
