Senior Node.js Developer for CMS Core Tech

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 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.

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.
• 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.
• Cloud & infrastructure: AWS SDK (S3, Bedrock), Docker/Docker Compose, Prometheus metrics, GitLab CI/CD

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.
