You’ll work on challenges like building intelligent search systems that surface perfect candidates from massive talent pools, creating AI tools that help recruiters craft personalized outreach, and extracting insights from candidate profiles and recruiting activity.

Familiarity with vector databases and embedding models for AI applications. Understanding of retrieval architectures and their implementation. Pragmatic approach to AI. You find the right balance between cutting‑edge techniques and scalable, maintainable solutions. How you work: Problem‑solving: You approach problems holistically, starting with a clear understanding of context. You navigate ambiguity well, decompose complex problems into clean solutions, and think critically about real‑world impact. Shipping quality products: You partner closely with product and design to craft experiences that feel effortless. You understand the balance between craft, speed and business impact. Communication and collaboration: You explain technical concepts clearly to both engineers and non‑technical stakeholders. You engage thoughtfully in disagreements and compromise when needed. Velocity and ownership: You’re excited by quick experimentation and continuous improvement. You take pride in shipping features from start to finish. User focus: You care about business impact and prioritize accordingly. You think critically about how your work shapes real people’s daily workflows.
