The Leidos Intelligence Group has an opening for a Chemical Engineer or a Chemist in Reston, Virginia. We are seeking a Senior Chemical Engineer or Chemist to lead reverse engineering analysis on defense industrial programs. You will leverage deep subject matter expertise to evaluate intelligence and open-source reporting, resolve contradictory data, and characterize lifecycles-from precursor development through Research and Develop, production, storage, and deployment. Work will be performed in a fast-paced, high-energy environment inside a government facility.
Primary Responsibility- Evaluate, contextualize, and deconflict all-source intelligence reporting, open-source data, and IC assessments regarding adversary chemical warfare capabilities in support of a common intelligence picture.
- Conduct technical analysis using chemical engineering and scientific principles to identify and bridge intelligence gaps.
- Characterize the adversary's end-to-end program, specifically detailing component procurement, precursor chemical synthesis, pilot and industrial scale production pathways, storage configurations, weaponization mechanics, and deployment methodologies.
- Evaluate foreign CW/WMD doctrine, strategy, stockpile logistics, and research, development, testing and evaluation (RDT&E) activities.
- Identify and monitor procurement and proliferation (P2) entities, supply chains, and dual-use technology transfers involved in the foreign trade of chemical weapons, CW-related components, and chemical precursors.
- Identify critical CW/WMD programmatic nodes, operational bottlenecks, and system vulnerabilities to support development of actionable concepts of operation and mitigation strategies.
- Produce detailed, executive-level technical assessments and briefings for government leadership and interagency partners.
Qualifications- TS/SCI Clearance is required to be considered. Must be able to obtain Polygraph.
- Must be a US Citizen
- Requires deep domain knowledge of chemical weapon lifecycles, agent synthesis, process thermodynamics, agent degradation, pilot to industrial-scale equipment, and production plant layouts. Serves as subject matter expert within the technical domain.
- Requires exceptional analytical problem-solving skills; proven ability to synthesize disparate, fragmented technical data through the application of advanced technical principles, theories, and concepts.
- Typically requires BS degree and 12 - 15 years of prior relevant experience or Masters with 10 - 13 years of prior relevant experience.
- Strong communication skills with the ability to engage senior leadership and clients on technical strategy and results.
Preferred Qualifications- 10+ years of specialized experience in solving DoD engineering and scientific problems.
- Direct experience with military operational planning and the functional defeat of hardened WMD targets.
- Proficiency with chemical process modeling software and data programming languages for dataset analysis.
- Strong working knowledge of standard IC and DoD databases (e.g., MIDB/MARS, TAC, Palantir) and cross-domain intelligence tools.
