About Throxy

Throxy builds vertical-specific AI Sales Agents for legacy industries where generic outreach tools fail. In just six months we’ve grown to >$1 M ARR. We’re looking for someone who can help us scale and keep accelerating.

What You’ll Do

  • Productionize AI agents at massive scale – design and extend the data-ingestion and orchestration layer that turns millions of raw company & people records.
  • Ship new agentic workflows – prototype end-to-end LLM playbooks (research, enrichment, multi-channel outreach) and push them to production in days, not months.
  • Frontend – craft real-time dashboards for customers.
  • Close the feedback loop – work on early versions of the first ranking models to create a self-improving outreach flywheel.
  • Scale with confidence – own performance, observability and reliability as we grow to hundreds of customers.

We’re Looking For

  • High agency, we believe agency will be the defining trait in the future of work.
  • 2-4 years shipping production code across TypeScript, React, Next.js.
  • Comfortable juggling imperfect specs, moving extremely fast, rapid iterations and an intense on-site cadence.

Why Throxy?

We’re a tight-knit team of engineers and operators committed to solving hard problems that push companies forwards. If this excites you, we’d love to hear from you. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.
