Recombee is a fast-growing hi-tech scaleup delivering next-gen recommendation and personalization solutions. We help our clients reach their business goals by applying advanced machine learning and AI to large-scale data, helping users discover products and content they will enjoy.

Our Tech Stack

• Primary language: Python · modern C++
• Architecture: Distributed microservices
• Databases: PostgreSQL · ClickHouse · Aerospike
• Messaging: Kafka
• API layer: GraphQL · REST
• Orchestration: Kubernetes (expanding)
• CI/CD: GitLab CI
• AI tooling: LLM APIs · AI-assisted coding

You don't need experience with every item above — we value curiosity and willingness to learn over a perfect match to any specific tool.

What You'll Work On

• Design and evolve components in our distributed microservice architecture — things that process serious data volumes with high availability requirements
• Build and maintain APIs consumed by client integrations worldwide
• Work across multiple database systems and contribute to decisions on when and how to use each
• Help shape our growing Kubernetes footprint as we expand our infrastructure
• Use AI tools and LLM APIs where they genuinely accelerate development — we're pragmatic about it

What We're Looking For

• Experience with distributed systems
• Comfort building or consuming REST or GraphQL APIs
• Working knowledge of SQL and an understanding of when relational storage fits (and when it doesn't)
• Familiarity with LLM APIs (OpenAI, Anthropic, or similar) or AI-assisted development tools — or genuine eagerness to get there
• A habit of thinking through operational consequences: latency, reliability, observability

Kubernetes experience is a nice-to-have, not a requirement — we'll grow together on that front.

What We Offer

• 5 weeks of vacation + 5 sick days
• Flexible hours — office-first with unlimited remote when you need it
• Experienced team with deep technical knowledge to share
• Office in the city center of Prague
• Mobile tariff with unlimited data
• MultiSport card

We offer a dynamic and international working environment, flat hierarchies, fascinating challenges, and great personal responsibilities.
