Careers

Help build the AI sales organization of the future.

Sellion is a seed-stage startup based in Austin, TX. We're building AI SDR pods that discover, negotiate, and hand off deals — with governance and observability that revenue, RevOps, and security leaders can trust.

Small team, big surface area: you'll work directly on core agent workflows, integrations, and customer deployments. We care far more about ownership and craft than about pedigree.

Why join at this stage?

This isn't a "wait for a ticket" environment. You'll be hands-on with customers, agents, infrastructure, and product decisions from day one. The work is messy, cross-functional, and deeply tied to real revenue outcomes.

  • • Ship features that get used by real GTM teams within days.
  • • Work at the intersection of foundation models, agents, and real-world sales workflows.
  • • Help define how AI SDR pods should behave, operate, and be measured — before it becomes the default.

Stage

Culture

Low-ego, high-ownership, biased toward shipping and iterating with real users.

How we work day to day.

  • • Small, focused pods owning outcomes — not long chains of hand-offs.
  • • Default to async clarity: specs, docs, and observability over meetings.
  • • Direct exposure to customers and their real workflows, not just tickets and mocks.
  • • We care about both velocity and correctness — especially in areas touching governance and revenue attribution.
