About Us

Reesi is an AI-first health tech startup that makes clinical trials radically more accessible and efficient. Our digital platform helps doctors to quickly find suitable oncological trials for their patients – for better treatment options and real advances in care. Over 150 clinics in Germany are already actively using Reesi. We focus on transparent processes, close collaboration with study centers, and real impact in the healthcare system.

You'll help shape the development of digital infrastructure in healthcare by advancing our Bubble.io platform, laying the technical foundation for scalability, and bringing innovative AI solutions into real-world use.

What You Will Do

• Hands-on Product Development: As our go-to full-stack Bubble developer, you’ll build features, MVPs, and refine user-facing components – from custom logic to intuitive UI/UX. While full-stack versatility is key now, specialization (e.g. frontend or backend) is possible as the team grows.
• Technical Ownership & Team Leadership: Reporting to our co-founder Christian (Product & Tech Lead), you’ll gradually take ownership of our tech domain – including architecture, workflows, and AI capabilities. You’ll lead hiring, mentor junior devs, and define scalable standards.
• Scalable Architecture & Tech Evolution: You’ll maintain a reliable, scalable foundation. Our stack includes Bubble.io, Cloudflare Workers, and AI integrations – with room to introduce traditional codebases as needed.
• AI-first Development & Automation: You’ll prototype and implement AI-powered solutions, especially LLM-based, to automate processes and enhance product intelligence – shaping an AI-first mindset across platform and tooling.
• Performance, UX & Quality: You balance technical rigor with design sensibility, turning complex logic into polished, user-friendly interfaces. You care about speed, responsiveness, and usability – even without a dedicated designer.
  
  

What You'll Bring

• Advanced Bubble.io expertise: At least 2 years of hands-on experience as a professional Bubble.io developer with high proficiency. Proven capability in advanced data modeling and performance optimization. Having a Bubble Developer Certification is a plus.
• Adaptability to a growing tech stack: Strong interest in working within an evolving technical environment. Comfortable exploring and integrating traditional codebases (e.g., Cloudflare Workers, Supabase) alongside no-code tools. Willingness to go deep into code when needed, with a mindset oriented toward scalability and modularity.
• Leadership potential: Demonstrated interest – or first experience – in hiring, mentoring, and leading a development team in a fast-paced startup environment.
• Data privacy & domain awareness: Experience handling sensitive data and working within regulated environments. A solid understanding of data privacy principles, particularly GDPR compliance, is essential in this role, given the healthcare context.
• Time zone compatibility: You are based in Germany or within a ±3 hours time zone difference from Berlin time, ensuring overlap with core team working hours. Travelling to our quarterly team meetings should also be no problem for you.
• Language skills: Full professional proficiency in English (spoken and written) is required. German language skills are a strong plus for collaboration with internal stakeholders and if needed, external communication with clinical partners in the DACH region.
• Healthcare industry experience is a plus: Experience in the healthcare or life sciences sector is an advantage, particularly in working with clinics, clinical research data, or medical workflows.
  
  

What we offer you

• Meaningful impact: We're not building another incremental feature – we’re addressing real structural problems in healthcare. Your work directly supports improved access to better clinical research and enhanced patient care.
• Fair compensation & VSOP: We believe in fair pay, which is why we openly discuss salary expectations from the first conversation. In addition, we offer mobility and lunch allowances, non-cash benefits, and participation in our growth through a VSOP (please note: some of these benefits only apply when you are based in Germany).
• Growth & development: We actively support your professional and personal development through challenging projects, regular feedback, and a high level of autonomy.
• Flexibility: Work remotely (with quarterly in-person team meetings) or from our base in Hamburg – whichever fits your life best. We also offer flexible working hours.
• Room to shape: Bring your ideas to life and actively contribute to shaping how Reesi grows as a product, an organization, and a team. You'll have a voice in technical, strategic, and operational decisions.
• A dynamic environment: Join a motivated, interdisciplinary team with flat hierarchies and fast decision-making. We cultivate an open communication culture, value honest feedback, and work together with respect and trust.
