Why this role exists:
We're looking for a strong individual contributor who owns complex backend features end-to-end — from technical design through production delivery. You'll work independently on challenging problems, write high-quality code at scale, and raise the bar for the team by mentoring less experienced engineers and maintaining engineering standards through thorough code reviews.
What you’ll drive:
Software Architecture and Backend Development
- Design and implement scalable, resilient backend services and APIs.
- Write, test, and debug complex code across new and existing applications.
- Own features end-to-end: from understanding requirements, through implementation, to production monitoring.
- Identify and resolve complex technical problems, including performance bottlenecks and architectural debt.
- Maintain comprehensive technical documentation for systems you build.
Collaboration & Mentorship
- Mentor junior and mid-level engineers through pairing, knowledge sharing, and day-to-day guidance.
- Conduct thorough code reviews to ensure quality, security, and adherence to best practices.
- Collaborate with cross-functional teams (product, design, operations) to clarify requirements and align on technical approach.
- Proactively communicate technical trade-offs and progress within the team.
What makes you a GR8 fit:
Must-have
- 5+ years of hands-on backend engineering experience with a strong track record of delivering complex systems.
- Upper-intermediate or higher level of English.
- Understanding of system design: microservices, event-driven architecture, resilient patterns, delivery guarantees, CAP theorem.
- Database knowledge: relational and non-relational databases, SQL optimization, indexing, normalization/denormalization, ACID properties, transaction isolation.
- Working knowledge of Docker, Kubernetes basics, CI/CD pipelines, and Git workflows.
- Advanced proficiency in Node.js and TypeScript, including runtime internals, event loop, async programming, and core modules.
- Advanced TypeScript: strict typing, generics, decorators, utility types, and metaprogramming patterns used in NestJS.
- Proficiency in designing and implementing scalable RESTful APIs and microservices using NestJS.
- Event-driven architecture: Kafka for async messaging, BullMQ for background job processing.
- Cloud & infrastructure: AWS SDK, Docker/Docker Compose, Prometheus metrics, GitLab CI/CD.
