Explore your future career  🔭   As a Senior Fullstack engineer at Malt, you will join a specialized squad (composed of Software engineers, Product Designer and Product Manager). Each squad is responsible for a specific business domain and will handle the full development cycle.

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.
