AI Engineer

Houston, Texas, United States

ON.energy is building the backbone of energy and AI infrastructure powering grid-safe data centers and mission-critical facilities. The company supplies and operates hyperscale power systems that solve the toughest resilience challenges, delivering custom solutions for AI data centers, mission-critical facilities, and front-of-the-meter assets. ON recently announced a 5GW partnership, with 3GW currently under construction across multiple hyperscale data center campuses. With patented technology and proprietary software, ON.energy develops projects worldwide that set new benchmarks for resilience.

Role Summary

This is the first dedicated AI engineering role at ON.energy. There is no established AI platform team to inherit and no fully scoped roadmap waiting for you; you will help decide what gets built, what gets bought, and what patterns the rest of the company adopts. If you want a role where the early decisions are still open, this is one. If you need a mature platform and a defined backlog on day one, it is not.
You will report to the Program Director, AI Enablement, who owns intake and prioritization of AI use cases from across the business. This is a small, direct working relationship where you will be the technical half of it. The role is based in Houston, with a minimum of three days per week in the office and a reasonable remote setup for the days you are not. Occasional travel should be expected.
 

Key Responsibilities

  • Building production AI systems end to end, from prototype through deploy and monitor — owning the delivery dates and milestones you commit to, and flagging risks and contingencies early rather than reporting them after the fact
  • Working directly with stakeholders across Engineering, Operations, HR, Finance, and Commercial to translate workflow problems into shippable tools, much of it in person and side by side with the teams whose work you are changing
  • Writing the evaluation harnesses, prompts, retrieval logic, and integration code that make LLM-powered features reliable
  • Establishing reusable technical patterns — prompt and model governance, eval frameworks, data access, deploy practices — built in partnership with IT so they fit our security, identity, and infrastructure standards
  • Partnering with external vendors and implementation partners: evaluating their platforms, holding them to scope and schedule, and integrating what they deliver into our stack
  • Contributing to the technical roadmap, including where to invest, what to kill, and what's worth building in-house versus buying
  • Partnering with the Program Director on technical scoping for new use cases, including calling out when an out-of-the-box tool will solve the problem versus when custom work is justified
  • Tracking how the AI tooling landscape is moving and folding what genuinely matters into our stack, including retiring approaches of your own when something better arrives

Key Requirements

  • A CS or related technical background, with hands-on production experience building AI/ML systems (internships, research, or full-time work all count)
  • Demonstrated ability to ship: a portfolio of projects or work history that shows you take things from idea to running system, not just notebooks
  • Solid software engineering fundamentals, including version control, testing, code review, and deployment practices
  • Working knowledge of modern AI tooling: LLM APIs, RAG, evaluation, agent frameworks, vector stores
  • Strong written and verbal communication. You'll be in front of non-technical stakeholders regularly and the work needs to translate
  • A track record as a true business partner. You scope realistically, commit to dates and milestones, think through risks and contingencies in advance, and raise slippage early instead of at the deadline
  • Ability to work as part of a team in a multi-stakeholder environment. There will be plenty of solo wins in this role, but many of the biggest ones will come through partnership with IT, the business, and outside vendors — and you should find that just as rewarding
  • A habit of staying on top of technology developments. This tool set changes quarter to quarter; you will need to evaluate what is new, form a point of view, and adapt without chasing every headline
  • Willingness to work in our hybrid, in-office culture — a minimum of three days per week in the Houston office, with a reasonable remote setup for the rest. We collaborate face to face with each other, with vendors, and with key stakeholders, and this role depends on that proximity
  • Comfortable in ambiguity. We don't have a fully scoped roadmap; you'll help build it
Preferred Experience
  • Production experience with hosted LLM platforms (Anthropic API, Azure OpenAI, AWS Bedrock, or equivalent)
  • Hands-on experience with Claude Code, MCP server development, or agentic coding tools
  • Familiarity with Microsoft ecosystem integration (Entra ID, Graph API, M365 surfaces) for enterprise AI deployments
  • Experience with agent orchestration frameworks or multi-agent systems
  • Exposure to settings where data sensitivity and operational safety constrain what you can deploy (OT, healthcare, finance, regulated industries)
  • Background in energy, utilities, or other operationally complex sectors
 
Not flexible on:
  • Having built something real people actually used, and having kept it running after launch. Prototypes and notebooks are not the same thing
  • The ability to work inside enterprise constraints. To include identity and permissions, data you are not allowed to move, systems you do not control or clear evidence you would pick that up quickly
  • Being in Houston and in the office at least three days a week
  • Doing what you said you would do, by when you said you would do it

  • Competitive salary + annual performance-based bonus eligibility

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
