About Braintrust

Braintrust is building modern, AI-enabled workforce and hiring technologies used by some of the world’s most innovative companies. Our products streamline complex workflows, improve decision-making, and connect organizations with highly qualified talent at scale.

We’re expanding our engineering team to build new capabilities across our platform—spanning talent management, workflow automation, client-facing tools, and internal operations systems. We’re looking for experienced full-stack engineers who enjoy solving complex system challenges and shipping high-quality products quickly.

The Role

As a Full-Stack Engineer at Braintrust, you will help design and build key components of our next-generation platform. You will work across backend services, data models, and user-facing interfaces to deliver scalable, performant systems used by internal teams, talent, and enterprise clients.

This role is ideal for engineers who thrive in high-ownership environments, enjoy building end-to-end features, and want to work on products at the intersection of AI, workflow orchestration, and large-scale operations.

What You’ll Do

• Build and maintain backend services and APIs powering core workflows across our platform.
• Develop intuitive, responsive frontend interfaces using modern web technologies.
• Design scalable data models and contribute to architectural decisions across systems.
• Own features end-to-end—from ideation to technical design, implementation, testing, and iteration.
• Collaborate closely with PMs, designers, AI engineers, and cross-functional partners.
• Improve reliability, observability, and performance across the stack.
• Contribute to foundational platform decisions as we expand into new capabilities.

What We’re Looking For

Required Qualifications

• 4+ years of experience building production-grade full-stack applications.
• Strong experience with full-stack TypeScript/Node.js (Next.js/TypeScript, React, or similar).
• Solid understanding of FAST APIs, microservices, and distributed architectures.
• Strong foundation in PostgreSQL databases, schema design, and data modeling.
• Experience designing or maintaining complex, multi-step workflows.
• Ability to turn ambiguous requirements into clear, actionable engineering plans.
• Excellent communication and collaboration skills.
• AI-native development mindset — highly efficient with AI-enhanced coding tools (e.g., Cursor), able to use AI to accelerate architecting, implementation, debugging, and tech debt cleanup.

Nice-to-Haves

• Experience building AI-powered features, semantic search, or ML-integrated systems.
• Background in B2B SaaS, HR tech, marketplaces, or workflow automation platforms.
• Familiarity with real-time systems, event/event-driven architecture, or data pipelines.
• Experience with financial or compliance workflows, invoicing systems, or multi-tenant architectures.
• Comfort working with distributed teams and async collaboration.

Who You Are

• You build clean, scalable systems that solve meaningful user problems.
• You iterate quickly and deliver high-quality work without heavy supervision.
• You think like a product owner and engineer.
• You embrace ambiguity and contribute actively to shaping product direction.
• You are energized—not threatened—by AI tooling, and you lean into it to multiply your impact.

Why Join Us

• Work on high-impact features used by enterprise clients and internal teams.
• Help shape the next phase of Braintrust’s platform evolution.
• Join a senior, tight-knit engineering team with strong ownership and autonomy.
• Build systems that power mission-critical workflows across an evolving product ecosystem.
