Join Our Mission

At Omega Technical Services, every role supports a mission that matters. Whether you're advancing national security, driving innovation in nuclear infrastructure, or supporting critical DOE and DoD operations, you’re part of something bigger here.

Omega Technical Services is seeking a highly motivated Structural/Mechanical Analysis Engineer to support ongoing operations in Idaho Falls, .

This position is contingent upon contract award and/or project funding. Candidates may be identified, screened, and submitted prior to award. Employment offers and start dates are dependent upon successful contract award, funding authorization, and client approval.

Provides structural and mechanical analysis support for elevated-temperature nuclear component design evaluations in accordance with ASME BPVC Section III, Division
5. This position is remote-eligible, with periodic coordination calls with technical leads expected; no mandatory on-site presence is required. Engagement duration and hours will be determined based on candidate availability and final scope assignment. Performs code-compliance analysis supporting the structural integrity of elevated-temperature nuclear components, including load-controlled stress evaluations, stress classification and linearization, and finite element model development. Supports the preparation of code-compliant, independently reviewable calculation packages and contributes to the technical rigor underpinning the design and safety basis of next-generation nuclear components.
