About the Role As a Backend Engineer, you'll be part of our Backend Engineering team, building the core services that power our platform. You'll work on scalable microservices, APIs, and data pipelines that transform raw sensor data into actionable insights for our customers. This role offers the opportunity to work across the full data lifecycle—from ingestion to delivery. What you will do: You'll design and develop scalable backend services and APIs, primarily using TypeScript/Node.js and Python. Your work will include building microservices that power our smart monitoring platform and working with GraphQL to expose data to frontend applications. You'll collaborate closely with Product Managers and cross-functional teams to deliver impactful features, contribute to architecture decisions, and help shape our engineering best practices. Code reviews and maintaining high-quality standards are a natural part of how we work together. Our Tech Stack We work with AWS cloud services (ECS/EKS, API Gateway, Lambda, Fargate), TypeScript/Node.js and Python, PostgreSQL and ClickHouse databases, Kafka for messaging, GraphQL APIs, and containerization with Docker and Kubernetes. What We're Looking For We're looking for someone with around 3+ years of backend engineering experience who enjoys building reliable, scalable systems. You're comfortable working with TypeScript/Node.js or Python and have experience with cloud services, preferably AWS. You understand how microservices and distributed systems work, and you value sound engineering practices such as testing, CI/CD, and collaborative code reviews. Fluency in English helps you communicate effectively with our international team. Proven experience collaborating with third-party stakeholders and communicating effectively throughout projects. Demonstrated track record in developing and/or integrating external APIs. Experience with streaming technologies like Kafka, stream processing frameworks such as Flink, or time series databases like ClickHouse would be valuable in this role—but if you're excited to learn these, that counts too. You don't need to check every box. If this role excites you and you bring relevant experience, we'd love to hear from you. How We Work We do Scrum with 2-week sprints and schedule most meetings in the mornings to preserve afternoon focus time. We work in a hybrid setup with regular office collaboration in Utrecht.
