Valar Atomics is a nuclear energy startup developing advanced small reactors and clusters of reactors to supply large-scale energy needs.
<p><strong>About Valar Atomics</strong></p> <p>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.</p> <p><strong><span data-contrast="auto">The Role</span></strong><span data-ccp-props="{"335559739":0}"> </span></p> <p><span data-contrast="auto">Valar Atomics is developing high temperature gas cooled small modular reactors from first principles spanning early R&D through licensing, construction, and commissioning. The Senior OT Data Engineer will own the operational data architecture connecting industrial sources, historians, time-series databases, semantic models, visualization, and controlled downstream consumers across Valar's reactor, fuel, and power-conversion programs. This is a hands-on role spanning software, databases, storage, networking, cybersecurity boundaries, and field commissioning.</span><span data-ccp-props="{"335559739":0}"> </span></p> <p><span data-contrast="auto">Your scope includes FactoryTalk Historian SE/AVEVA PI, InfluxDB/SQL, OPC UA/MQTT/APIs, ETL/data pipelines, semantic data models, Grafana, virtualized data services, RAID/ZFS storage, backup/recovery, high-rate time-series data, data quality/lineage, and controlled transfer through air-gapped/unidirectional boundaries to enterprise/cloud systems.</span><span data-ccp-props="{"335559739":0}"> </span></p> <p><span data-contrast="auto">You will work closely with the Senior SCADA Engineer, Senior OT Network Engineer, Senior OT Infrastructure Engineer, IC&E, Operations, Quality, and engineering users.
