Head of Medical Human Resources

T1 Energy is bringing solar manufacturing back to the U.S. by building a domestic solar supply chain. Our mission is to invigorate America with scalable, reliable, and low-cost energy. Our fully operational 5GW solar module facility in Wilmer, Texas, can manufacture more than 20,000 modules every 24 hours. By the time you finish reading this paragraph, we will have produced two solar panels that will power American homes and fuel domestic AI. We're focused on building advanced American manufacturing and we're passionate about engineering a better future filled with abundant energy.

T1 Energy is looking to hire a Manager, HR Benefits to own the full benefits function for a fast-growing manufacturing company. This is a hands-on, operational position for someone who knows benefits administration from the inside out: plan setup, carrier feeds, billing reconciliation, open enrollment, compliance, and everything in between. That means the data is right, the feeds are running, the invoices match, and employees get answers, not runarounds.

If you've built or run a benefits operation in a high-growth environment, thrive on process and precision, and take genuine pride in a clean reconciliation and a well-run open enrollment, this role was made for you. Administer all benefit plans: medical, dental, vision, FSA/HSA, COBRA, life/AD&D, disability, supplemental, 401k, and executive plans, and manage enrollments, terminations, and qualifying life event changes in UKG Pro. Maintain accurate eligibility and coverage records as the authoritative system of truth, and reconcile enrollment data against carrier records on a regular cadence.

Vendor Management & Employee Support
Serve as the primary point of contact with carriers and vendors, coordinate issue resolution, and keep policy numbers, contacts, and plan details current at all times. Field employee benefits questions, own the escalation path when coverage doesn't match enrollment, and coordinate corrections with carriers on the employee's behalf — making sure people get the coverage they're entitled to without having to fight for it.

Compliance, Documentation & Tracking
Maintain SOPs, process documentation, and current plan documents so operations don't live in one person's head and changes are clearly communicated to stakeholders. Deeply familiar with UKG Pro and how benefits administration works inside an HRIS, not just around it.

Deep working knowledge of medical, dental, vision, FSA/HSA, COBRA, life/AD&D, disability, 401k, and supplemental plan administration.
~ Experience monitoring and troubleshooting carrier EDI feeds, including reading and working 999/TA1 acknowledgments.
~ Proven experience with self-bill reconciliation and carrier invoice management.
~ Solid understanding of benefits compliance requirements including ACA, ERISA, HIPAA, and COBRA.
~ High attention to detail and a track record of keeping enrollment data clean and audit-ready.
~ Bachelor's degree in Human Resources, Business, or a related field preferred.
