Key responsibilities ✨

Collaborative Product Leadership: You'll establish a strong partnership with Product Managers and Designers to translate user needs into innovative technical reality. You thrive in the creative process, confidently challenging ideas and co-creating elegant solutions that directly solve end-users problems.
Take the lead: You’ll own your features end-to-end. From first sketch to release (and beyond). You’re empowered to make decisions and trusted to do what’s right for the product.
Build smart, ship fast: We deploy to production around 70 times a week. You’ll help us keep that rhythm by balancing speed, quality, and business impact.
Be a partner: You bring strong opinions, backed by experience, and you’re not afraid to challenge the status quo when it makes sense.
AI-Augmented Craft: You are curious about (or already using) tools like Cursor, Gemini or Claude Code. You see AI as a pair-programming partner that accelerates delivery while you maintain the "human-in-the-loop" for quality and strategy.
Knowledge Multiplier: As a senior, you’ll help the team navigate this new AI landscape. You’ll share best practices on prompt engineering, AI-driven refactoring, and maintaining a high "quality bar" in an automated world.

Frontend: TypeScript, Vue.js, Nuxt, Internal Design System, Stencil.js

Backend: Kotlin, Java Spring Boot, Gradle, PostgreSQL, MongoDB, Elasticsearch, RabbitMQ, Redis

Platform: Google Cloud Platform, Kubernetes, Terraform, ArgoCD, Gitlab CI

The AI Toolkit: We empower our devs with modern AI coding assistants and are building internal workflows and investigating as many uses as possible (docs, unit tests, migrations)

Data: BigQuery, dbt, Looker, Spark, Python

Bring 6+ years of professional software development experience, including a first role within a product company (SaaS, fintech, marketplace, etc.)

Demonstrate deep proficiency in Java or Kotlin, with confidence in navigating complex backend architectures, APIs, and data models.

Product-First Champion: You think beyond the code, driven by curiosity about the user's "why." You proactively propose improvements and champion end-to-end feature ownership from conception to delivery.

Pragmatic Architect: You drive architectural decisions, leveraging patterns like Hexagonal Architecture for modularity and testing. You skillfully balance long-term scalability with the need to iterate quickly

AI Empowerment: You view AI as an accelerating force, effectively delegating routine tasks to tools while remaining the strategic "Pilot" responsible for quality, integrity, and preventing architectural drift.

Full Lifecycle Stewardship: You maintain stewardship over the entire feature lifecycle. From building CI/CD and testing to ensuring observability and monitoring. Shipping is just the start; you are dedicated to quality, longevity, and scalable performance.

Fluent in English, you are comfortable speaking and writing in an English-speaking environment.
