We’re looking for the first Generative AI Engineer to help Unit grow into the GenAI era across all fronts.

This role blends strategic technical leadership with hands-on development, making it ideal for someone excited to both deliver features today and shape where we go tomorrow. KEY RESPONSIBILITIES

• Own the infrastructure: deploy and operate AI systems on AWS (and/or other providers where appropriate), ensuring reliability, security, and cost-effectiveness.
• Collaborate with product and engineering teams to identify opportunities for GenAI = across Unit’s platform and processes, understand team-specific domains, and embed agents directly into existing business workflows.
• Build frameworks and internal tooling that empower other teams to adopt GenAI safely and efficiently.
• Establish best practices around evaluation, model iteration, and observability.
• Serve as a multiplier: educate and support peers in understanding and using GenAI capabilities within their domains.

• Eng leadership experience (former Tech Lead, Staff Engineer, VP Eng).
• Strong backend development experience with modern engineering practices and production infrastructure.
• Experience in the full GenAI lifecycle: model selection, benchmarking, optimization, deployment, and monitoring.
