Assistant System Engineer Jobs in Vienna, VA (NOW HIRING)

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.

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.

• TS/SCI with Poly Required

• Preferred Qualifications: Exposure to MBSE/SysML, DoDAF, or enterprise architecture concepts, Familiarity with requirements/tools (e.g., Jira/Confluence, DOORS, Cameo, or similar).

System Engineer II

• 5-9+ years of relevant systems engineering experience.
• Demonstrated experience with requirements management and development of engineering documentation.
• Experience working in a structured delivery environment (Agile, iterative, or traditional engineering lifecycles).
• Bachelor’s Degree in Engineering, IT, Business, or related field
• Preferred Qualifications: Experience with MBSE/SysML and/or architecture frameworks (DoDAF), Familiarity with integration, verification, and configuration management practices, Prior support to U.S. Government programs (DoD/Federal/Civil).

System Engineer III

• Bachelor’s degree in Engineering, IT, Business, or related field; Masters Preferred
• 10+ years of experience.
• Experience serving as a lead/architect on complex integrated systems in mission environments.
• MBSE/SysML and architecture framework proficiency (DoDAF) and familiarity with formal review processes (SRR/PDR/CDR).
• Relevant certifications (e.g., INCOSE ASEP/CSEP, AWS/Azure, Security+), as appropriate to the SOW.
• Preferred Qualifications: Experience serving as a lead/architect on complex integrated systems in mission environments, MBSE/SysML and architecture framework proficiency (DoDAF), and familiarity with formal review processes (SRR/PDR/CDR).

Pay Range: VTG’s estimated starting pay range is $100,000 - $205,000 annually, which is a general guideline for the geographic location. When extending an offer, VTG also considers work experience, education, skill level, market considerations and may possibly include contractual requirements which may cause an offer to fall outside of this range.
