About Cori
At Cori, we're transforming the future of clinical trials.
The work that brings new therapies to patients is slowed down by outdated, manual, regulatory tasks. We’re changing that — by building the AI platform that automates the complex, painful processes behind clinical research. Faster science means faster cures — and we are here to make that happen.
We’re an early-stage, venture-backed company with a clear mission: eliminate bottlenecks in clinical research, and give scientists the tools they deserve.
We move fast. We build with care. We solve problems that matter.
Why This Role Matters
As our Founding Back-End Engineer, you won’t just write code — you’ll shape the foundation of Cori's platform and help define how life-saving therapies move from idea to reality.
You’ll work directly with the founders to translate messy, high-stakes clinical workflows into intuitive, intelligent tools. You'll architect the systems that power AI agents, RAG pipelines, and document intelligence — and you’ll ship product that clinicians and biotech companies actually love using.
You’ll be a true owner: of your projects, your decisions, and the results you create.
If you’re looking for a “steady” job where you do what you’re told, this is not for you.
If you’re here to build, to ship, and to matter — welcome to Cori.
What You’ll Do
* Architect and build AI-native back-end systems from scratch (Python, FastAPI).
* Deploy intelligent, production-grade AI applications into real-world clinical environments.
* Design and optimize RAG pipelines, agent workflows, and knowledge graph integrations.
* Own your work end-to-end: from design to deployment to iteration.
* Collaborate closely with the founders and shape Cori’s technical and product strategy.
* Solve problems that have no obvious answer — and create better solutions than anyone expects.
What are we looking for
·Advanced Python (experience with FastAPI is preffered)
·Proven experience in building and deploying AI applications to production.
·RAG and Agent Workflows: Experience designing retrieval-augmented generation pipelines and agentic systems
·Startup Readiness: Comfort with ambiguity, autonomy, and evolving roadmaps. Willingness to learn and creativity to come up with practical solutions to complex problems.
Nice to have
·Cloud & DevOps: Experience with AWS, CI/CD, and infrastructure as code
·Security: Knowledge of OAuth2, encryption, and regulated system design
·Healthcare or Life Sciences Experience: Familiarity with standards like HIPAA, GxP, or ICH-GCP
·NLP Expertise: Experience training and deploying NLP models
·Advanced Data: Hands-on work with vector or graph databases
What We Offer
* Top-of-market salary + meaningful equity — real ownership, real upside.
* High-trust environment — work with autonomy, be treated like an owner.
* Mission-driven product — your work helps accelerate life-changing research.
* Growth alongside a world-class team — founders and early team with deep AI and clinical experience.
* Finally, we don't do story points ;)
