Who We Are

We're a team of founders, engineers, researchers, creatives, and operators building what we believe will be one of the defining companies of the AI era.

Some of us came from startups. Some from academia. Some from hospitality, defense, design, or completely different worlds. We don’t care how you got here - we care about your energy, intelligence, curiosity, resilience, and ambition.

Who We Are Not

• We are not remote. We value the spontaneous moments that happen when we’re together - over dinner, in the hallway, around whiteboards. We like being around each other because the best conversations here rarely happen in meetings.
• We are not your typical team. It’s not just the 10 countries we’re from, the languages we speak or our non-traditional backgrounds. We’re solving hard problems with people we respect - we make the most of our time together, we make it special.
• We are not another “polished” SF startup. We value velocity over speed, raw talent over brands, and genuine human connection above all else. We value being successful, not looking successful.

What You’ll Own & Build

As a Member of Technical Staff within the Engineering Tribe, you won’t just be writing code - you’re building the product and the systems that turn simulated behavior into real product decisions.

You’ll work across the stack, connecting complex backend systems (multi-agent simulations, evaluation pipelines) to frontend experiences that customers rely on to decide what to build next.

• Core Platform: Build and evolve the Seldon platform (Python) - the system customers use to design experiments, run simulations, explore behavioral outputs, and decide what to ship.
• Agent to Product Translation: Turn raw agent behavior into product functionality, bridging the gap between “what the system did” and “what the user should do next.” Strong application of agentic systems is the baseline.
• System Visibility & Trust: Build tooling that makes the system understandable and trustworthy.
• User Agency & Decisions: Help define how users interact with simulations and make decisions.
• Velocity & Ownership: Work in tight loops - ship fast, learn faster. Own features (backend → frontend → user impact), ship bi-weekly, and define best practices as we scale.
