Sterling Engineering & Consulting

What Sterling Engineering & Consulting does

Sterling Engineering & Consulting (SE&C, LLC) is a privately held professional services consultancy headquartered in Richland, Washington, operating as a subsidiary of Enveniam Solutions. Founded in 2014, the firm provides executive management, project management, business development, and technical consulting services to the U.S. Department of Energy (primarily the Office of Environmental Management and the National Nuclear Security Administration), the Department of Defense, NASA, and commercial clients in the energy, environmental remediation, national security, and mining sectors. SE&C's core capability is human capital: it draws from a network of more than 65 subject matter experts and more than 100 senior associates, with leadership averaging over 30 years of DOE and nuclear sector experience, to deliver short- and long-term consulting assignments and embed SMEs into client capture teams.

SE&C delivers its services through three productized lines: Strategy and Business Development Consulting (executive advisory, capture planning, strategic planning), Proposal Development Services (managed by the proprietary EDGE2win methodology that covers full proposal lifecycle from capture planning through orals training), and Staffing Solutions (deployment of SMEs and senior associates into client task orders). The firm reports an 85% contract win rate over 10 years and references 23 U.S. DOE prime contracting opportunities valued at over $83 billion that it helped clients capture, though these are client awards rather than SE&C's own revenue. Notable clients include Fluor, Leidos, AECOM, KBR Wyle Services, Jacobs, Amentum, Energy Solutions, Atkins, Huntington Ingalls Industries, Navarro Research and Engineering, and Fluor Idaho. The founder, Duane Schmoker, holds U.S. and international patents for nuclear material monitoring and storage technologies.

The business model is professional services delivered on a per-engagement basis. Pricing is not publicly disclosed and is negotiated per scope, expertise required, and assignment duration. The go-to-market motion is enterprise field sales led by senior executives (Managing Director, EVP, SVPs) leveraging personal networks within DOE, DOD, and commercial energy sectors, supported by a limited digital presence (LinkedIn, corporate website) and direct outreach. SE&C is a bootstrapped firm with no disclosed funding rounds or institutional investors, operating with 11-50 employees and a single headquarters office in Richland. Geographic reach extends beyond the U.S. into the United Kingdom, Sweden, and Japan, though the U.S. federal market, and DOE in particular, remains the dominant revenue base.

Broad incumbents

• AECOM: Global engineering and environmental services firm with deep DOE and federal nuclear/environmental work. Both a current SE&C client and a structural competitor in adjacent DOE opportunities.
• Huntington Ingalls Industries Technical Solutions: Large federal services division covering nuclear operations, environmental remediation, and DOD logistics. Overlaps with SE&C in DOE cleanup, decontamination and decommissioning, and DoD mission support, while operating at substantially greater scale.
• SAIC: Large federal IT and engineering services contractor with extensive DOE, DoD, and federal civilian work. Operates in the same proposal/capture ecosystem as SE&C while offering a much broader service portfolio.
• Leidos: Major federal services and IT contractor with a sizable DOE and environmental portfolio (including NETL research support). Competes with SE&C's clients for capture work and increasingly offers in-house proposal and capture management depth.
• Jacobs Solutions: Global engineering and federal services firm with significant nuclear, environmental, and DOE program presence. Competes with SE&C-adjacent primes for DOE contract recompetes and brings substantial in-house capture capability.

Direct peers

• Navarro Research and Engineering: DOE-focused technical and environmental services contractor. Directly comparable to SE&C in DOE nuclear and environmental work and a current SE&C client, reflecting head-to-head competition for similar capture and proposal engagements.
• Strategic Management Solutions (SMS): Small woman-owned consulting firm supporting DOE Hanford, NNSA, and environmental management programs with technical and program management staff. Highly comparable niche and customer overlap.
• Longenecker & Associates: Boutique DOE/nuclear technical and management consulting firm providing SMEs to Hanford, NNSA, and other federal sites. Closely mirrors SE&C's lean, talent-led model serving the same customer base.
• Battelle Memorial Institute: Large nonprofit operator of DOE national laboratories and federal energy/environmental programs. Comparable in deep DOE technical and program management expertise, with similar capture-management and SME deployment models at sites like Hanford, NETL, and Idaho.

Emerging players

• Boston Government Services: Specialized DOE/nuclear technical services firm supporting EM, NNSA, and NRC programs. Comparable SME-led nuclear and environmental consulting model with growing federal footprint.
