Job Summary
Why Reesi Exists
Every year more than 500000 people in Germany are diagnosed with cancer. For many of them a clinical trial could be the best available treatment option yet only 5% ever participate.
Not because trials dont exist. But because doctors often dont know which trials are running where and whom to contact.
Reesi is changing that.
Were building Europes search and matching platform for oncology trials giving physicians and patients the fastest most accurate way to understand which trials are a fit.
With Reesi doctors can find suitable trials in minutes transparently data-driven and securely. Were also partnering with leading media companies to bring this access directly to patients.
Traction: 250 hospitals 1000 physicians. Now were scaling across Europe.
Tasks
The Role
Youll build the backbone of Reesis next evolution evolving our production platform into a unified scalable system that can serve physicians and patients across Europe.
The core challenge: unifying systems streamlining data flows and building the next layer of our backend architecture.
We already have a working platform (Bubble frontend Cloudflare Workers for heavy logic Supabase as our emerging data layer). Your job is to turn these components into one cohesive architecture and extend our custom-code foundation.
Youll work directly with the founders (medical doctor experienced entrepreneur) and our small engineering team.
Youll have real room to shape the architecture and set foundational patterns for the entire platform.
Full-Stack Ownership
Although this role is backend- and architecture-heavy you will work across the full stack when needed. At Reesi engineers own features end-to-end:
- End-user-facing UI: Youll implement polished production-quality interfaces based on designer-provided mockups.
- Internal tools & dashboards: Youll build simple functional UIs yourself not pixel-perfect but clear usable and reliable for daily workflows.
- Backend data and AI logic: You own the logic that powers both internal and external systems.
If you enjoy building complete slices of a system from database models to backend services to the UI that exposes them this role is a great fit.
If you prefer a backend-only role with no UI involvement this role wont be the right match.
AI is part of our core workflow and we expect you to use modern AI tools to accelerate development structure logic and support decision-making.
What Youll Work On
Platform & Data Architecture
- Build and evolve our Supabase/Postgres setup (schemas RLS auth edge functions)
- Model complex domains: clinical trial parameters medical indications sites patient attributes
- Connect Bubble Cloudflare Workers and Supabase into a unified platform
- Design internal and partner-facing APIs for trial data
Migration & Scalability
- Extend our custom-code layer and gradually move core workflows to a scalable architecture
- No big-bang rewrite pragmatic modular evolution
- Build new features directly on top of a future-proof backend
- Ensure readiness for European-scale usage
Backend Services & Infrastructure
- Expand and maintain Cloudflare Workers for business logic and data pipelines
- Build services that support AI-driven workflows and matching algorithms
- Monitoring logging performance and reliability improvements

AI-Powered Matching
AI is at the heart of Reesi.
Youll build the technical foundations that allow us to:
- match patients to trials using complex medical features
- run intelligent search and decision-support workflows
- integrate continuously evolving AI models
- automate complex medical data interpretation

About Company
Every year many cancer patients never learn about clinical trials that could help them not because the trials dont exist but because the information is fragmented inconsistent and difficult to search. This challenge delays over 80% of clinical trials and prevents more than 30% of eli ... View more
