Job Description

Backend Expert, Node.js

intent

• Own and evolve the backend architecture for IoT projects: from data ingestion pipelines to API design to infrastructure decisions • Make technical trade-off decisions and defend them clearly to the team and to clients • Design and maintain cloud infrastructure on AWS (EKS, Aurora, DynamoDB, Timestream, S3) with production-grade reliability • Lead technical discussions: RFCs, architecture reviews, post-mortems. Not because someone asked you to, but because you see the need • Mentor other backend engineers, raise the bar on code quality, and set patterns others can follow • Collaborate closely with firmware engineers, mobile developers, QA, PMs, and clients • Use AI tools as part of your daily workflow, not as a party trick • Challenge product and technical assumptions when something doesn’t make sense, even if it means a harder conversation

Job Requirements

  • 7+ years of backend development experience, with a meaningful chunk spent leading technical direction, not just writing code
  • Deep, hands-on AWS expertise: EKS, Aurora, DynamoDB, Timestream, S3, IAM. Not 'I set up an EC2 once'
  • Strong Node.js skills in production systems at scale
  • Kubernetes (EKS), Docker, and Terraform: you’ve built and maintained real infrastructure, not just followed tutorials
  • Solid understanding of distributed systems, event-driven architectures, and data pipelines
  • Experience with MQTT or similar IoT messaging protocols
  • CI/CD pipelines you’ve designed yourself (Jenkins, GitLab CI, GitHub Actions)
  • English at B2+ minimum, written and spoken: you’ll be in rooms with US-based clients and you need to hold your own
  • The ability to translate business needs into technical decisions and explain those decisions to non-technical stakeholders
  • Strong opinions, loosely held: you propose direction, you defend it, and you change your mind when the evidence says you should

Benefits

  • Truly flexible hours (most of the team works 10-18 CET, but you organize your day)
  • Fully remote, with Warsaw office + Gdansk cowork if you want them
  • Access to our internal knowledge-sharing: tech talks, experiments, side projects
  • A genuine path to the core team: if the first 3 months go well, you get a permanent contract with a fixed monthly salary regardless of project availability, 26 days paid leave, 10 sick days, Saltus medical care, training budget, and mentoring budget
