Software Engineer (Forward Deployed Agent Builder)

Join Brex, a fast-growing financial technology company, as a Software Engineer focused on building AI agents to automate and enhance internal functions. In this role, you will work closely with various teams across the company to understand their workflows, design and deploy agents, integrate them with internal systems, and measure their performance. You will have the opportunity to make a significant impact on the company's operations and contribute to the development of cutting-edge AI technology.

• Collaborate with cross-functional teams to understand workflows and design, build, and deploy AI agents that automate and augment internal functions.
• Integrate agents with internal systems, APIs, and data sources, and define evaluation frameworks, success metrics, and feedback loops to measure and improve agent performance.
• Build shared tooling and contribute to playbooks that accelerate deployments, while owning reliability, adoption, and business impact.
• Hands-on experience building with LLMs, agent frameworks, and tool-use patterns (e.g., MCP, function calling, RAG) across the full stack (data, APIs, orchestration, product)
• Strong ability to decompose human workflows into scalable, agentic systems, grounded in a deep curiosity for how people work
• Experience designing and optimizing SQL and/or NoSQL databases, including data modeling, query performance tuning, and schema design
• 4+ years in engineering, technical product/program management, applied AI, or a similar technical role, with a track record of shipping AI/automation systems to production
• High ownership and cross-functional influence, with the ability to quickly build trust across teams and seniority levels
• Experience with OpenClaw, Hermes, or other general-purpose agent harnesses
• Experience automating back-office functions rather than just customer-facing AI features
