Talent Pool | Data, Machine Learning & AI

What if you could talk to 10,000 people before making a decision?

That's what Galaxies does. We build Synthetic Personas — models that simulate real audiences so marketing, product, and innovation teams can test hypotheses before spending months and millions finding out an idea didn't work.

The technical challenge

Reliably simulating human behavior is one of the hardest problems in applied AI today. A well-prompted LLM isn't enough — it takes real technical depth, and a question nobody has answered definitively yet: how do you prove a synthetic persona is right?

If that question gets you going, we'll probably get along.

What you'll find here

• Startup scale, lab-grade problems. We're a lean team. There's no layer of bureaucracy between you and a real technical decision. What you propose on Monday can be running by Friday.

• Real enterprise clients. What you build ends up inside decisions made by brands reaching millions of consumers. Feedback is real, and it comes fast.

• Uncharted territory. A lot of this still has no playbook (sometimes not even in the market). If you like being the first person to solve something, you'll thrive here.

• Actually remote, from day one. No office, no city requirement, no presence theater.

Profiles we're mapping

• Machine Learning Engineer — training, fine-tuning, and evaluating models in production

• AI/LLM Engineer — LLM-based systems, RAG, agents, evaluation, and inference optimization

• Data Engineer — pipelines, data quality, and architecture at scale

• Data Scientist — statistical modeling, experimentation, and product-applied analysis

• Data Analyst — analysis that turns into decisions, not just a pretty dashboard

• Advanced English: we're preparing for international expansion, and English will be required soon.

All seniority levels. If your profile is a hybrid or doesn't fit neatly into any of these titles, even better — send it anyway.

How it works

Our Data & AI team grows alongside the product, and our best hires started as a conversation, not a selection process.

Sign up here and your profile joins our active pool: when we open a position on this front, people in the pool are the first to know — before any public posting.

No cover letter needed. Just send your LinkedIn or resume.
