Leidos; Herndon (VA); On-site; USD 73,000 - 133,000; Full time

Job summary

Leidos is seeking an experienced Environmental Compliance Auditor to lead multimedia environmental audits nationwide for federal and commercial clients. The role focuses on planning, fieldwork, findings, reporting, and client briefings with substantial travel across the United States and territories.

You will identify compliance gaps, develop defensible recommendations, and mentor junior auditors while expanding environmental services, especially in Texas and West Coast markets.

Qualifications

• Bachelor's degree in Environmental Science, Environmental Engineering, or related field with at least 4 years of progressively responsible environmental compliance auditing or assessment experience.
• Demonstrated experience independently leading multimedia environmental compliance audits, from planning and fieldwork through findings development, reporting, and client briefings.
• Strong knowledge of federal environmental regulations, including RCRA, CAA, CWA, SDWA, OPA, EPCRA, TSCA, and CERCLA, along with working knowledge of applicable state and local requirements.
• The ability to interpret complex environmental regulations, evaluate facility operations, identify compliance gaps, and develop practical, technically defensible recommendations.
• A proven track record of producing high-quality technical reports and conducting thorough QA/QC reviews, with exceptional attention to detail and accuracy.
• Strong organizational and time-management skills, with the ability to manage multiple audits, competing priorities, and deadlines without sacrificing quality.
• Leadership capabilities, including experience guiding or mentoring others and the ability to take on increasing project management responsibility.
• Experience or demonstrated aptitude in coordinating project schedules, budgets, resources, and deliverables.
• Strong consulting and interpersonal skills, with the ability to build credibility quickly, work effectively with diverse stakeholders, and represent Leidos professionally in client-facing environments.
• Excellent written and verbal communication skills, including experience delivering formal technical briefings and presenting findings to facility and senior leadership.
• Proficiency with Microsoft Office and experience using environmental audit databases or electronic compliance reporting systems.
• The ability to work independently, exercise sound professional judgment, and deliver results with limited supervision.
• The willingness and ability to travel 50%–75% nationwide, including consecutive weeks of travel, to support environmental compliance programs across the United States and U.S. territories.
• Must have a valid driver's license.

Responsibilities

• The audit, start to finish. You'll independently plan and lead multimedia environmental compliance audits at government and commercial facilities — from pre-audit research and regulatory reviews to facility inspections, personnel interviews, documentation reviews, and final reporting.
• The regulatory picture. You'll evaluate compliance with federal, state, local, and agency-specific environmental requirements across air quality, drinking water, wastewater and stormwater, hazardous materials, solid and hazardous waste, storage tanks, spill prevention, and toxic substances.
• The findings that matter. You'll look beyond identifying violations to understand root causes, recognize positive practices, and develop clear, defensible findings and corrective action recommendations that drive meaningful, lasting improvements.
• The quality of the work. You'll set a high standard for technical accuracy, consistency, and completeness — reviewing your own work and that of other auditors to ensure every finding, report, and client deliverable is accurate, defensible, and ready for submission.
• The client conversation. You'll lead entrance and exit briefings, present findings to facility managers and senior leadership, explain regulatory requirements, and provide practical guidance and training that helps clients improve compliance.
• The project execution. You'll help manage audit schedules, budgets, resources, team coordination, and deliverables — taking on increasing responsibility for project performance as our programs expand.
• The team. You'll guide and mentor less experienced auditors, share technical expertise, and help build a team known for professionalism, sound judgment, and exceptional work quality.
• The client relationship. You'll serve as a trusted advisor who understands the client's operations, anticipates challenges, and brings solutions rather than simply identifying problems.
• The growth. You'll look beyond the current audit to identify emerging client needs, strengthen existing relationships, support proposals, and help expand Leidos' environmental compliance services across government and commercial markets, particularly in Texas and along the West Coast.
