Senior TypeScript SDK & Platform Engineer

MiLaboratories | Bilbao, Spain | ONSITE | RELOCATION SUPPORT | https://platforma.bio We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—the foundational infrastructure where all biological data is transformed into life-saving breakthroughs. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + deep biological nuances) requires high-bandwidth, in-person collaboration. We dissolved traditional departmental silos. We are hiring hardcore builders, not analysts, for a critical core role: *Senior TypeScript (SDK & Platform):* You will architect our frictionless, AI-native SDK to scale our ecosystem. This is not a CRUD web dashboard. You will build a heavy local desktop application that bridges directly with a high-performance Rust data layer. You must treat the browser engine as a runtime for heavy local apps. The standard is simple: if the SDK is too messy for us to build blocks at AI-speed, it is too messy for the world. The Offer: * Comp: Top-tier EU salaries (€90k - €120k EUR). * Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions - up to 50% in total). * 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 [at] milaboratories [dot] com. Please mention "HN" in the subject and include your GitHub.
