AI Engineer

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
