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.

Our Tech Stack

  • 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

Life @Malt

  • Remote Culture: Strong remote culture with most of the team working full-remote from countries where Malt has a physical office and legal entity (France, Germany, Spain, Belgium, Netherlands, or UK).

  • Tech Days: 15% of engineering time dedicated to technical project, , continuous training and learning, R&D and technology watch.

  • Tech Conferences: Annual Product, Tech and Data workshop, annual Malt Tech Days, organized and presented by Malt’s engineering team. Opportunity to attend major tech conferences.

About you 🧑‍🚀

  • 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.
