## Job description

## About Valar Atomics

At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable—unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.

The Team

As part of the Engineering organization, Instrumentations & Controls designs the systems that monitor, automate, and protect Valar's facilities and reactor technologies. The team develops reliable control architectures that enable safe and efficient operations.

## The Role

Valar Atomics is a young startup that turns ambitious engineering into working hardware. Before our third anniversary, we designed, built, commissioned, and operated a DOE-authorized research reactor outside the national laboratory system. That pace defines how we work: learn quickly, make sound decisions, and build systems that perform. Safe operation, disciplined testing, and regulatory rigor are non-negotiable. Analysis must lead to decisions and delivery, and we expect people to take ownership and see their work through. If you want hard problems, real responsibility, and the freedom to build with urgency, bring your judgment and drive to Valar.

Own the reactor program's daily OT work plan, team workload, and delivery commitments. Keep installation, testing, maintenance, and handoffs moving as site readiness and program priorities change, with clear expectations and calm follow-through. Technical expertise is preferred, not required; people-management and decision authority develop through explicit delegation.

OT Engineering delivers power and rack infrastructure, compute, networks, identity, security, operational data, and industrial software platforms. The FactoryTalk scope covers backend deployment, configuration, integration, and recovery.

## Key Responsibilities

- Plan and prioritize reactor OT work against site access, installation readiness, test prerequisites, available resources, and agreed commitments.
- Assign work, set clear expectations, coach team members, give candid feedback, and address missed commitments within delegated authority.
- Maintain a current view of site work, vendor activities, dependencies, and unresolved issues; revise the plan when conditions change.
- Coordinate installation, testing, maintenance, and turnover with engineers and site stakeholders.
- Maintain as built structured cabling drawings for site and reactor network systems
- Remove obstacles, resolve competing demands on the team, and escalate constraints before they threaten committed work.
- Obtain required engineering and acceptance decisions, then follow the agreed work through verified completion and accurate handoff records.

You Will Be Successful in This Role If

- Highly organized, with disciplined task tracking, accurate documentation, clear priorities, and reliable follow-through.
- Calm direction when site conditions or priorities change, with timely decisions and escalation.
- Consistent coaching, candid feedback, and fair accountability that improve team performance.
- Highly proficient in contractor management and leading a team that is majority contractors for a time
- Clear ownership of daily commitments and timely adjustment of plans when prerequisites or resources change.
- Discipline in checking agreed readiness conditions and obtaining engineering direction before affected work proceeds.

## Basic Qualifications

- Direct people-management or supervisory experience, including assignments, expectations, coaching, feedback, and accountability for completion.
- Experience coordinating concurrent technical or operational work involving specialists, vendors, resources, schedules, and dependencies.
- Ability to maintain clear priorities, realistic work plans, accurate status and issue records, and dependable follow-through under pressure.
- Experience removing delivery obstacles, escalating consequential issues, and coordinating handoffs against engineers' requirements and acceptance decisions within delegated authority.
- Coordinate site work and handoffs against installation readiness, approved test prerequisites, and engineering acceptance decisions.
- Technical specialization is preferred, not required. Qualified nontechnical people managers are eligible; hands-on engineering execution is not required.

## Preferred Skills and Experience

- Experience leading installation, commissioning, maintenance, or test-facility work.
- Experience coordinating work across engineering, construction, operations, and vendors.
- Familiarity with OT infrastructure, controlled work processes, or facility testing.

## What We Offer

- Competitive base salary
- Equity ownership in a rapidly growing advanced energy company
- Comprehensive medical benefits
- Unlimited PTO
- Free daily lunch and dinner provided onsite
- Generous PPE stipend
- High-impact startup environment with significant ownership and autonomy
- Opportunities for rapid career growth and internal advancement
- Direct collaboration with experienced operators, engineers, and industry leaders
- The opportunity to help build and scale transformative energy technology from the ground up

## About Valar Atomics

## Company Overview
- **One-liner**: Valar Atomics is scaling nuclear energy through grid-independent, high-temperature gas reactors (HTGR) for hydrogen production, data center power, heavy industrial power, and clean hydrocarbon fuel synthesis.
- **Entity Type**: Private (total funding $494M–$600.5M, latest round Debt - II)
- **Headquarters**: El Segundo, California, United States (additional location in Orangeville, Utah)
