Technical Lead — AI-Driven Biotech & Drug Discovery

Equity-based | Boston, MA | Pathway to co-founder or CTO

Who We Are

Collixion Therapeutics is an early‑stage biotech developing therapies for women with gynecological cancers who relapse after targeted treatment – the patients who run out of options when they need them most.

What This Role Is

We are building at the intersection of AI and drug discovery in gynecological cancer. The technical territory spans several areas and we are looking for someone who is strong across most of them and excited to grow in the rest.

Computational biology and genomics

• Worked with and analyzed large‑scale biological datasets from public sources
• Differential expression analysis, pattern recognition, and biological interpretation of cancer cell line and patient tumor data
• Understanding of how gene expression data is structured, normalized, and made meaningful in a research context

AI and machine learning

• Building AI‑powered applications that turn biological data into structured, interpretable predictions
• LLM API integration – designing prompt architectures that produce scientifically grounded outputs
• Knowing when AI adds genuine value and when simpler statistical approaches are more appropriate

Software and platform development

• Python proficiency – building pipelines that process, analyze, and output biological data reliably and reproducibly
• Experience deploying functional applications that non‑technical collaborators can interact with
• A builder instinct – you write code to ship things that work, not to demonstrate technical elegance

Valued but not required

• Background in computational biology, bioinformatics, systems biology, or biomedical engineering
• scRNA‑seq analysis experience
• Prior experience at an early‑stage biotech, research startup, or translational academic lab
• Genuine curiosity
