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.
