AI Engineer

VectorShift (YC S23) is building the AI enterprise workflow automation. We convert complex, manual processes into fully automated AI systems that scale across global teams. ABOUT THE ROLE As an AI Engineer, you will work across our core AI infrastructure — from multi-agent systems and RAG pipelines to evaluation frameworks and production deployment. You'll ship AI-powered features that clients rely on daily, ensuring they're performant, reliable, and secure. This is a high-ownership role where you'll contribute across the full stack: backend APIs, data pipelines, frontend interfaces, and cloud infrastructure. You'll report directly to the founders and collaborate closely with a tight-knit engineering team building product with real urgency and craft.

The work is hard, the pace is fast, and priorities will shift as we learn from the market and our clients. You need to be comfortable with ambiguity and energized by building something that hasn't been built before. We're assembling a small team of exceptionally talented, tenacious people who care deeply about the craft of building great software. If that's you — and you're at the point in your career where you want to make a defining contribution — we'd love to hear from you.
