> Build software systems to automate commissioning of AI data center infrastructure. Generate test procedures, schedules, and automated L4/L5 execution from a live knowledge graph; integrate with BMS/EPMS and ship agentic LLM tools to commissioning engineers on factory floors and live sites. Requires production coding in Go/Python/TS, LLM/agent frameworks, and field credibility with controls experts.

## Job Description

## Responsibilities
- Generate commissioning test procedures per asset from the design revision and spec, across all five levels.
- Gap-check vendor FAT procedures automatically against project requirements and Tier standards.
- Build the commissioning schedule as software: factory acceptance tests, witness tests, and on-site L1 through L5 sequencing across vendors, trades, and buildings, with dependencies enforced and replans computed dynamically.
- Automate L4 and L5 execution through the BMS and EPMS on live sites and factory floors: drive setpoints, inject failures, and capture controller responses over open protocols.
- Land every result, issue, and corrective action in the knowledge graph tied to the exact asset for automated energization gates, handover, and continuous improvement of test plans.

## Requirements
- Shipped production code in Go, Python, or TypeScript, and can pick up whatever language the problem needs.
- Built working systems with LLM APIs (OpenAI, Anthropic, or open-weight models), MCP servers, and agentic frameworks, and shipped them to real users.
- Work daily in AI coding tools like Claude Code or Cursor and run agents autonomously to multiply output.
- Found problems independently, designed fixes, and shipped them end-to-end without waiting for approval.
- Ship fast on foundations that other engineers extend; past teammates continue to build on your work.
- Earned credibility with hands-on experts (commissioning agents, controls engineers, contractors) and got them to adopt tools built in the field.
- Sweat product and design details so users can tell.

## Nice-to-Haves
- Commissioning levels and FAT programs.
- BMS/EPMS and control protocols (BACnet, Modbus).
- PLC/SCADA.
- Critical power and cooling equipment.

## Compensation & Benefits
