We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate antibody discovery and drug development.
We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.
We are hiring for two core roles:
1. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.
2. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology.
The Offer:
Comp: Top-tier EU salaries (~€90k - €120k).
Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).
The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.
Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."
Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).
Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.
Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.
