Full-Stack Engineer, Quatt Product

QuattAmsterdamHybridFull-time30 Sept 2026

Quatt is seeking a Full-Stack Engineer to join its Software & Infrastructure team in Amsterdam, working on a real-time IoT platform for sustainable home energy solutions. The role is backend-focused (80%) with some frontend work, requiring strong TypeScript, Node.js, and cloud infrastructure experience. The company aims to accelerate the energy transition and assist 3 million households by 2030.

What you'll do

Build and evolve the backend behind our customer app, installer tools, and internal dashboards — from device commissioning flows to energy insights and smart-control features.
Work on our telemetry pipeline: ingesting, processing, and querying second-level data from tens of thousands of heating systems and batteries (AWS IoT Core, SQS, ClickHouse, BullMQ).
Build the energy side of our platform: home-battery charging strategies, dynamic energy tariffs, and integrations with energy-market and EMS systems.
Design APIs (OpenAPI) and integrate with third-party platforms such as HubSpot and field-service systems.
Help architect our cloud infrastructure as the fleet grows — performance, scalability, observability, and cost.
Build and own our internal and support dashboards (React) — the tools our support and operations teams rely on to manage the fleet and help customers.
Contribute to our customer and installer app (React Native) where product work spans the full stack.
Collaborate with cross-functional teams (app, embedded, hardware, data) to ship new features across the Netherlands.
Troubleshoot and resolve production issues across the pipeline, from device message to API response.
Own the health of the platform: alongside new features, you'll pick up maintenance work, dependency upgrades, refactoring, fixing legacy corners, and improving reliability.
Together with the team, brainstorm ideas on how to improve our internal processes and help us grow.
