Senior Node.js developer

We're looking for a Senior Node.js Developer to join the team behind a mature, mission-critical SaaS platform serving the aviation industry. Trusted by 13,000+ active users worldwide, the platform supports document management, regulatory compliance, and core operational processes for aviation businesses.

This is an opportunity to take real ownership of an established backend platform — maintaining and evolving it — while also contributing to new features and architectural improvements. You'll be working with a modern, cloud-based tech stack built around AWS, with a strong emphasis on scalability and engineering best practices. The roadmap is stable and long-term, giving you the chance to influence technical direction rather than just execute tickets.

What You'll Do

• Take ownership of key areas of an established Node.js backend platform, ensuring reliability and performance for a large, active user base

• Design, build, and maintain scalable backend services and APIs

• Contribute to architectural decisions as the platform evolves and grows

• Manage and configure cloud infrastructure — including servers, networking, deployments, scaling, and monitoring

• Work hands-on with AWS services, particularly ECS (Elastic Container Service), to deploy and run containerized applications

• Collaborate with the team on new feature development while maintaining and improving existing systems

• Help drive engineering best practices across the codebase and infrastructure

What We're Looking For

• 5+ years of professional software development experience.

• Strong experience  with Node.js

• Solid knowledge of SQL databases

• Hands-on, practical experience with AWS infrastructure — not just consuming managed services, but setting up, configuring, and managing cloud environments yourself

• Experience with ECS (Amazon Elastic Container Service) specifically

• Experience configuring and managing servers, networking, deployments, scaling, and monitoring

• Experience with Docker and containerized applications

• Strong understanding of scalable backend architecture and distributed systems

• Confidence taking ownership of infrastructure decisions and driving them forward

• Upper-Intermediate English (B2+) or higher.

Nice to have:

• Experience with AWS Lambda

Why This Role

• Work on a mature, mission-critical product with a large, established user base

• Real ownership of a backend platform — not just feature work

• Long-term roadmap with room to influence technical decisions

• Modern, AWS-centric cloud stack focused on scalability and best practices

• Stable, established product in a niche, regulation-driven industry
