Back-End Engineer New Test 101

About the Role

We’re looking for a Backend Engineer to design, build, and scale reliable APIs and services that power our products. You’ll work with product, frontend, and infra teams to deliver secure, performant, and well-tested systems using Node.js (TypeScript) or Python/Java, with a strong focus on databases, distributed systems, and cloud deployments.

Key Responsibilities

• Design, build, and maintain scalable REST/GraphQL APIs and background workers.
• Model data and write efficient queries for PostgreSQL/MySQL/MongoDB; manage migrations.
• Implement caching (Redis), message queues (Kafka/RabbitMQ), and async workflows.
• Own service performance, reliability, and observability (logging, metrics, tracing).

Requirements

• 3–5 years backend experience with Node.js (Express/NestJS) or Python (Django/FastAPI) or Java (Spring Boot).
• Strong SQL and schema design; familiarity with ORMs (Prisma/TypeORM/SQLAlchemy/Hibernate).
• Experience with caching, queues, and event-driven architectures.
• Solid grasp of system design fundamentals (scalability, consistency, CAP, idempotency).
