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. Job Description 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. 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‑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.
