Our ambition drives us. Our people make it real.
If you’re a challenger in spirit and a champion in action — join us.
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.
Software Architecture and Backend Development
Design and implement scalable, resilient backend services and APIs.
Write, test, and debug complex code across new and existing application.
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.
Must-have
5+ years of hands-on backend engineering experience with a strong track record of delivering complex systems.
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.
Strong problem-solving skills: ability to break down ambiguous problems, make pragmatic decisions, and communicate reasoning clearly.
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 (modules, providers, guards, interceptors, microservices transport, Swagger).
Event-driven architecture: Kafka for async messaging, BullMQ for background job processing.
Nice-to-have
Experience with Go or .NET.
Experience with Strapi CMS or similar headless CMS platforms.
Familiarity with Terraform/Terragrunt for infrastructure-as-code.
