Original job description

Lyntris is a defense technology company that connects sensing to action across the connected battlespace. Lyntris brings together the talents of Accelint and Vitesse teams under one mission, with each contributing deep expertise within their domain. Combining differentiated hardware, software and mission expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed, precision and confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch - including Navy, Army, Air Force, Space Force and allied partners - spanning strategic, operational and tactical missions and every domain: Space, Air, Land, Sea and Cyber. With more than 200 active defense programs, Lyntris works at every level of the mission, from national command authority to the tactical edge.

Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over. Lyntris moves faster than the traditional defense cycle - with integrated design, build and test capabilities in-house - and delivers systems that sustain and endure long after initial fielding.

Job Description

Cybersecurity Systems Engineer II
Full time
Onsite / 5 days a week

Develop, review, and maintain technical documentation, including Systems Engineering Plans (SEPs), system specifications, interface documentation, engineering change requests, test procedures, and other program engineering artifacts.
Support engineering change requests (ECRs), configuration management activities, technical reviews, and approval processes to maintain system baseline integrity and ensure compliance with established engineering standards.
Collaborate with Government program managers, lead engineers, cybersecurity specialists, developers, test organizations, configuration management personnel, and Fleet stakeholders to coordinate technical activities and resolve engineering challenges.
Evaluate engineering approaches, system architectures, technical dependencies, and proposed solutions. Identify risks, assess operational impacts, and develop actionable recommendations and mitigation strategies.
Coordinate engineering activities supporting system integration, verification, validation, operational testing, installation planning, and Fleet deployment readiness.
Track engineering activities, technical action items, schedules, milestones, and deliverables. Prepare status reports, technical assessments, briefings, and recommendations for Government leadership.
Support the integration of cybersecurity requirements and Risk Management Framework (RMF) considerations into system design, development, testing, and sustainment activities.
Identify opportunities to improve engineering workflows, technical documentation, requirements traceability, and cross-functional coordination.

Required Qualifications

Currently holds an active U.S. national security clearance or be able to receive and maintain one. To learn more about the security clearance process please access this link.
Bachelor's degree in Engineering or a related technical discipline. Relevant professional experience may be considered as a substitute, subject to contractual requirements.
3–5 years of relevant experience in systems engineering, technical program support, cybersecurity engineering, or a related discipline.
Working knowledge of systems engineering lifecycle processes, including requirements analysis, system design, integration, verification, validation, and sustainment.
Experience developing, reviewing, or maintaining technical documentation, engineering artifacts, or system requirements.
Understanding of cybersecurity fundamentals, system architectures, network technologies, and security principles.
Demonstrated ability to coordinate technical activities across multidisciplinary teams and manage competing priorities.
Strong analytical, problem-solving, organizational, and written/verbal communication skills.
Ability to independently research technical issues, evaluate alternatives, and develop recommendations.
Proficiency with Microsoft Office applications, including Excel, Word, PowerPoint, and Microsoft Project or equivalent scheduling tools.
CompTIA Security+ certification.
Active DoD Secret security clearance with ability to become TS/SCI Eligible.

Desired Qualifications

Experience supporting U.S. Navy, NAVWAR/PEO C4I, PAE MS, or other DoD acquisition programs.
Familiarity with DoD systems engineering policies, technical review processes, and acquisition lifecycle requirements.
Experience with engineering change management, configuration control boards, system baselines, and engineering review processes.
Familiarity with DoD cybersecurity requirements, Risk Management Framework (RMF), NIST security controls, and Assessment and Authorization (A&A) processes.
Experience supporting cybersecurity systems, defensive cyber operations, network defense, or enterprise security architectures.
Familiarity with requirements traceability, interface management, system integration, and test planning.
Familiarity with U.S. Navy ashore systems fielding processes, including the Fleet Readiness Certification Board (FRCB) process, installation planning, technical readiness assessments, and coordination of system deployment and operational acceptance activities.
Experience with Navy engineering and program management tools such as CMPRO, RIPTIDE/SPIDER, or equivalent platforms.
CISSP or relevant systems engineering/cybersecurity certifications.
