As an AI Engineer at TestZeus, you will take ownership of designing, building, and maintaining production-grade LLM-based systems that power our core testing platform. You’ll work closely with cross-functional teams (backend, product, design) to ship features quickly, test with real users, and iterate in production. You’ll also play a key role in defining evaluation metrics, optimizing prompts and retrieval flows, and helping the team stay current with the latest research. This role is ideal for someone who has already delivered LLM applications end-to-end and wants to deepen their expertise in retrieval-augmented generation (RAG), prompt workflows, and agent-driven evaluation.

You’ll be the first GTM hire focused squarely on accelerating growth through smart content distribution, building our organic community, and scaling a repeatable engine for brand awareness and demand generation. We believe that great growth starts with trust and trust is earned through value-driven content, conversations, and systems. This role is designed for someone who lives at the intersection of creativity, metrics, and compounding distribution.

We’re looking for a razor-sharp BDR who thrives in zero-to-one chaos, loves talking to people, and wants to own pipeline and revenue from day one. You’ll be the first full-time BDR hire and work directly with the founders to scale our outbound motion. You’ll prospect, qualify, run outreach campaigns, and book meetings. Within 90 days, you’ll start running demos. Within 12 months, you could be closing deals or leading a team. Yes, dangerously fast.
