Senior Full Stack Engineer

Highlights:

• Full-stack IC role, no management — ship product features end-to-end
• Stack: React, TypeScript, Kotlin, Spring Boot, PostgreSQL, AWS, Kubernetes
• Remote-friendly with regular in-person team days in Milan
• Small team, high ownership, direct access to the CTO
• We are a Claude Code shop and we use it extensively. Vibe coding is not our culture: every line ships with intent, and all code gets reviewed.

Cuebiq turns raw mobility data into measurement and advertising analytics products, without compromising user privacy. We’re hiring a Senior Full-stack Engineer to partner directly with Product and own the surfaces our customers actually use — from React/TypeScript frontend to Kotlin/Spring Boot backend to PostgreSQL data modeling.

What you’ll do

• Ship user-facing features and own their implementation — push back on requirements that don’t add up
• Lead frontend delivery: propose patterns, keep the UX bar high (loading states, error handling, accessibility)
• Build the backend APIs and data layer your features need, with full autonomy across the stack
• Prototype, ship, measure, iterate based on real usage
• Raise the quality bar through code review and engineering best practices

What you bring

• Proven product instinct — you’ve shipped product surfaces, not just internal tools
• Strong hands-on experience with a modern component-based frontend framework (React + TypeScript strongly preferred)
• Solid backend experience in a strongly-typed language (we use Kotlin/Spring Boot)
• Comfort with relational databases and schema design (we use PostgreSQL)
• Fluent English — you’ll work closely with US-based product teams

Nice to have: Figma/design sensibility, direct Kotlin/Spring Boot/PostgreSQL experience, micro-frontend patterns (single-spa), REST API design depth, cloud-native/microservices experience.

Perks: Milan office with fully-stocked kitchen and ping pong table, full public transport coverage, dedicated budget and time for professional development.

Salary range: €40.000-€55.000
