Software Engineer, Forward Deployed Agent Builder

Brex • Seattle, WA

14h • Hybrid

About The Position

Brex is seeking a hands-on builder to join their team in creating AI agents to automate and augment internal functions. The role involves embedding with teams across the company to understand their workflows, then designing, building, and shipping agents that deliver real outcomes. You will work with existing models and frameworks, integrating tools, MCPs, and internal systems into agentic workflows. This is a technical role focused on building, shipping, and iterating alongside the people whose work is being automated.

Requirements

• 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.
• 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).
• Experience designing and optimizing SQL and/or NoSQL databases, including data modeling, query performance tuning, and schema design.
• Strong ability to decompose human workflows into scalable, agentic systems, grounded in a deep curiosity for how people work.
• High ownership and cross-functional influence, with the ability to quickly build trust across teams and seniority levels.

Nice To Haves

• Experience automating back-office functions rather than just customer-facing AI features.
• Experience with OpenClaw, Hermes, or other general-purpose agent harnesses.

Responsibilities

• Embed with partner teams to deeply understand workflows, including shadowing and learning different job functions.
• Scope, design, and deploy agents that take over real workflows across internal orgs.
• Integrate agents with internal systems, APIs, and data sources.
• 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.

Benefits

• Global corporate cards and banking
• Intuitive spend management
• Bill pay
• Travel software
• AI-native automation
• World-class service
• Tools, resources, and support for career growth
• Equity and other forms of compensation may be provided as part of a total compensation package
