9 Mothers Defense | Robotics Engineer, Data Scientist | Austin TX | Full-time | ONSITE

We're building AI-driven turrets that stop hostile drones - where robotics needs F1-level speed.

We're looking for smart, T-shaped teammates: people who are experts in one area but happy to jump in wherever needed. Our software team is small, so every member makes a real impact.

If you want to write motor control in Rust, optimize camera processing with custom CUDA kernels on Jetson, or rework a transformer-based tracker to handle small objects - you can do that here, and much more.

MiLaboratories | Bilbao, Spain | ONSITE | VISA SPONSORSHIP | RELOCATION SUPPORT

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.

You: Hungry, self-directed, comfortable on the phone. Bonus: E-rate/EdTech/GovTech experience.

Founder-track role. Small technical team (ex-Google, GitHub) and seasoned sales team (20+ years in telecom).
