• Design and build robust, scalable APIs and distributed systems that power our products and deliver exceptional performance
• Collaborate closely with Product, Frontend, and Design teams to translate product ideas into well-architected backend solutions
• Push the boundaries of what's possible with modern backend technologies, driving innovation in both architecture and developer experience
• Contribute to evolving our backend architecture, infrastructure, and developer tooling to support rapid iteration at scale

What you'll need

• 5+ years of professional backend engineering experience, ideally in fast-paced startup or high-growth environments
• Deep expertise in Python and FastAPI, with a proven track record of building and scaling production systems
• Experience designing and implementing APIs (REST, GraphQL, or gRPC) that power user-facing products
• Strong experience working with SQL databases (e.g. PostgreSQL), including schema design, query optimization, and data modeling for production systems
• Familiarity with cloud-native architectures, ideally on GCP (e.g. Cloud Functions, Cloud Tasks, Firestore)
• Strong communication skills and a high sense of ownership - able to operate with autonomy while staying aligned with team goals

Nice to have

• Familiarity with DevOps practices, CI/CD pipelines, and infrastructure-as-code
• Familiarity with Vertex AI and ML specific infrastructure
• Background working on AI products or data-heavy applications
• Experience building and scaling a system that handled significant traffic or complexity

What they offer

• Exciting and challenging work with real impact and ownership at one of Europe's fastest-growing Series A startups
• Aggressive equity compensation package
• Hybrid (minimum three days in the office)
• Paid Dinner & Uber home when working late
• Regular team events and off-sites
