System Engineer with Security Clearance

Overview VTG is looking for a System Engineer in Chantilly, VA. (Note: Contingent upon program award). System Engineer I supports systems engineering activities under the direction of senior engineers and the Task Order PM. Assists with requirements support, documentation, traceability, and engineering analyses to help the team deliver compliant, testable, and supportable solutions aligned to Government mission needs. Engineer II performs systems engineering tasks with limited supervision, translating mission needs into system requirements and engineering products.

Coordinates across stakeholders to maintain technical alignment, supports design trade studies, and ensures requirements are verifiable and traceable through implementation and test. Engineer III provides senior technical leadership for systems engineering across the program, serving as the technical integrator to ensure solutions are coherent, compliant, testable, and aligned to Government mission outcomes. Leads requirements strategy, architecture development, and cross-team integration, and advises the PM on technical risks, tradeoffs, and execution priorities. What will you do?

System Engineer I

• Assist with requirements elicitation, documentation, and traceability (e.g., supporting requirement decomposition and maintaining requirement artifacts).
• Support creation and upkeep of systems engineering documentation (e.g., CONOPS inputs, interface notes, architecture products, technical descriptions).
• Participate in engineering reviews and working groups; capture notes, action items, and decisions and support follow-through.
• Assist with verification/validation support activities (test planning inputs, defect tracking support, requirements-to-test traceability).
• Coordinate with cyber, software, network, and test teams to support integrated delivery.

System Engineer II

• Lead/support requirements development, decomposition, and management; maintain end-to-end traceability from mission needs through verification.
• Develop and maintain systems engineering artifacts (e.g., system specs, interface documentation, architecture views, technical baselines).
• Support integration planning and coordination across engineering disciplines (software, network, cyber, cloud, test).
• Contribute to technical reviews (SRR/PDR/CDR or equivalent), including preparing materials and closing review actions.
• Support verification planning and test readiness activities; ensure requirements are measurable and testable.
• Identify technical risks/issues and propose mitigations; support configuration and change control processes.

System Engineer III

• Lead systems engineering approach across lifecycle: requirements strategy, architecture, interfaces, integration, verification, and technical baseline management.
• Own/oversee development of key systems engineering products (e.g., system requirements, interface control documentation, architecture packages, technical plans).
• Drive cross-functional technical integration, resolving design conflicts and ensuring alignment across software, infrastructure, cyber, data, and test.
• Lead technical reviews and decision forums; develop trade studies and recommend solution paths based on cost/schedule/risk/performance.
• Establish and enforce requirements quality standards (measurable, testable, traceable) and manage impacts of change requests.
• Mentor junior/mid engineers and implement engineering best practices to improve quality and delivery predictability.
• Provide technical input for program reporting, risk management, and customer briefings. Do you have what it takes?
• TS/SCI with Poly Required
