MiXCR is the standard for immune analysis, cited in thousands of papers. Platforma is the OS on top — bioinformatics as self‑serve, interoperable "blocks" for biologic discovery.

5 of the top 10 pharma (Moderna, Pfizer, others) run discovery with Platforma today. Goal: 10 of 10 by year‑end. Hiring 4–5 engineers in 90 days. Our tools are in the methods of approved cancer immunotherapies and COVID vaccines reaching millions. The next paper citing us could be the next drug.

We merged frontend, bioinformatics, and data into one team. AI killed the silo wall. Bioinformaticians who leaned into engineering and engineers who leaned into biology now ship at multiples.

• Discovery pipelines: raw sequences → pre‑IND leads. Antibodies, biomarkers, workflows real scientists use.
• The SDK for comp scientists:
  Type Script, Tengo (a Lua‑like workflow DSL — yes, you'll learn it), Rust.
• The data layer: thousands of formats reduced to one. PFrames, Parquet, Data Fusion, lazy columnar everything.

• Strong TS in 100k‑line monorepos (pnpm, Turbo). Polars > pandas. Node ≥22.
• Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity.
• Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it."

• €90–120k base, real ESOP, ARR‑tied bonus — when we grow, you grow, in cash, this year.
• Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net.
• Visa, relocation, soft‑landing. No HR, no take‑homes. Direct line to engineering.
• Bilbao: ocean, mountains, Michelin, low cost of living, highest quality of life. Onsite — context‑sharing needs same room.
