About the role

We're looking for a Director of Product Engineering to lead the team building Braintrust's core product experience. This is a hands-on engineering leadership role for someone who cares deeply about both building great products and great engineering teams. You'll shape how we build: setting technical direction, raising our product bar, and growing an exceptional product engineering team.

What you'll do

• Build and lead an exceptional product engineering team. Build a culture of ownership, ambition, and consistently strong execution.
• Make Braintrust's UI exceptional. Raise the bar across interaction design, performance, reliability, and product polish.
• Own the technical direction of the product. Evolve our frontend architecture to support increasingly sophisticated workflows, larger datasets, and a rapidly growing customer base without sacrificing speed or quality.
• Stay close to the product, customers, and code. Work alongside Product and Design to understand our users, shape the roadmap, and make the technical decisions that matter most.
• Deliver ambitious product capabilities at scale. Lead the team building experiences like our prompt playground, prompt management and versioning, multiplayer human review, and LLM analysis across arbitrarily large datasets.
• Build products at the frontier of how teams work with AI. From prompt experimentation and versioning to multiplayer review and large-scale LLM analysis, you'll lead the engineering behind some of our hardest product problems.

Ideal candidate credentials

• A proven engineering leader who has built, managed, and scaled high-performing teams, with a track record of recruiting exceptional engineers and developing future leaders.
• Exceptional product judgment and UI craft. You know what separates a good product from a world-class one and care deeply about usability, performance, interaction design, and the details.
• Deep technical expertise in modern web applications. You've built sophisticated, data-intensive products and are comfortable with technologies like TypeScript, React, SQL, and Next.js.
• A builder's mindset. You can think about organizational strategy one minute and dig into an architecture decision the next.
• High ownership and a bias toward action. You thrive in high-moving environments, make pragmatic decisions, and know how to create teams that move quickly without sacrificing quality.
• Experience with startups or AI is valuable, but not required. We'd especially value experience building LLM-powered products or leading teams through rapid growth.

Benefits include

• Medical, dental, and vision insurance
• Daily lunch, snacks, and beverages
• Flexible time off
• Competitive salary and equity
• Wifi & cellphone stipend
