Remote Senior Full Stack Engineer

In a few years, every physical product sold in the EU will carry a digital identity - a scannable record of where it came from, what it's made of, and what happens to it next. That's not a prediction. It's regulation.

Tappr is the platform brands use to build and manage those Digital Product Passports. When a consumer scans a QR code on a jacket or a pair of shoes, they land in an experience we power: sustainability data, care guides, warranty support, resale options - all branded, all compliant, all live. We connect brands' existing product data to that experience, and we make it work at scale.

We're a small team based in Rotterdam and Warsaw. We move fast, we're backed, and the market is coming to us.

• 5+ years of engineering experience with strong product instincts
• Strong Python - Django is our core, and most of the logic lives here
• Solid TypeScript, React and Tailwind - you'll be shipping frontend regularly, not occasionally
• Real experience with REST APIs, webhooks, and the messiness of real-world data (JSON, XML, CSV)
• GCP experience, or a strong AWS/Azure background you can transfer
• Comfortable using AI coding tools (Claude, Copilot or similar) - we expect everyone on the team to use them as part of their normal workflow
• Based in Europe, self-directed, and comfortable in a small async team where nobody will hand you a ticket queue

Nice to have:

• Hands-on experience with ERP or PIM systems (SAP, Akeneo, inRiver, or similar)
• Familiarity with GS1 standards or supply chain data formats

• Build and evolve our Python/Django backend - new API endpoints, data models, async jobs, performance improvements
• Ship frontend features in TypeScript and React across the Passport Builder and brand-facing tools
• Own reliability and observability on GCP - you'll be the one who notices when something's off before a client does
• Shape architecture decisions as we scale to more brands, more products, more markets
• Design and ship the integrations that connect client ERP, PLM, and PIM data into the platform when we onboard new brands
