Senior Fullstack Engineer

Who you are

• You have several years of professional experience as a Fullstack Engineer, ideally with Elixir or another Ruby
• You care about code quality, but not for its own sake - you balance pragmatism with craftsmanship
• You love working in small, empowered teams where you can shape not just the product but also how it’s built
• You come with a product mindset: if something’s unclear, you explore it instead of waiting for perfect specs
• You understand the basics of GDPR and secure software design and know why that matters
• You’re curious, reflective, and enjoy learning – including from failed experiments
• Professional-level English is required; German is a plus
• You can work remote from germany, but hybrid in Berlin would be ideal – that’s where our product and design team sits
• Experience with handling sensitive data, ideally health-related data
• Solid understanding of encryption, key management, and data privacy
• Knowledge of DevOps and hosting environments
• Familiar with Shape Up as an outcome-driven, autonomy-based approach for agile software development

What the job involves

• We’re looking for a Senior Elixir Fullstack Engineer to join our empowered product team, building simple, elegant software from complex requirements
• This is real product work - meaningful, fast-paced, and focused on impact
• We’re a small, hands-on team that owns a single product end to end
• Build and maintain a high-quality, maintainable codebase written in Elixir with Phoenix, LiveView, TailwindCSS and daisyUI
• We are building the product in small iterations, we prototype early and often, everybody is encouraged to move forward on their own accord
• Collaborate closely with Product, Design, and other Engineers to find smart solutions that balance speed, quality, and simplicity
• Shape our architecture for reliability, scalability, and developer happiness - we’re building a long-term platform here
• Build a clean, maintainable and tested codebase
• Take ownership of privacy and security aspects from the start - encryption, data separation, and GDPR compliance are part of the product, not an afterthought
• Contribute ideas to improve our development process, stack, and team culture
