Lead AI Engineer

This is a fully remote position, open to applicants in Mexico.

📋 Description

• Develop and enhance the evaluation pipeline, focusing on how we assess task completion, identify regressions, and convert production failures into corrected behaviors.

• Manage context effectively: determining what the agent perceives, when it does so, and ensuring coherence in long-term tasks without excessive token usage.

• Create sub-agent patterns: establish when to branch out, how to cleanly compose specialized agents, and maintain the parent agent's control over the final results.

• Oversee document parsing: converting supplier-uploaded invoices, catalogs, and contracts into structured contexts that the agent can analyze.

• Transform Coupa supplier APIs into agent-accessible CLI tools, ensuring clear error surfaces and reasonable defaults for agent users.

• Develop supplier-facing capabilities built on the harness: procedural instructions and tool compositions that enable the agent to manage specific tasks from start to finish.

• Troubleshoot complex production behaviors: investigate why the agent chose a specific path, where confusion arose, and what changes to tools, context, or the harness can resolve it.

• Collaborate with the senior engineer on architectural decisions regarding the harness as you identify gaps while working throughout the stack.

⛳️ Requirements

• Possess 3–5 years of experience in delivering production software with strong proficiency in Python (TypeScript is a plus).

• Have successfully launched at least one LLM-powered feature or product, regardless of size, and be able to discuss challenges faced and lessons learned.

• Be a frequent and heavy user of agentic coding tools such as Claude Code, Cursor, Codex, or similar alternatives.

• Have personal projects that demonstrate your passion and creativity, ideally ones that were made feasible by the new generation of AI tools.

• Communicate fluently in English, both in writing and speaking, as skill authoring is detail-oriented and the team operates in English.

• Approach debugging methodically by analyzing logs, traces, and evaluations rather than through speculation.
