Join a dynamic, mission-focused team We are seeking a Deputy Chief Engineer to serve as the senior technical authority and platform modernization lead for a large-scale, mission-critical defensive security engineering program. This individual will own the end-to-end technical vision, enforce architectural discipline across integrated security platforms, and drive measurable improvements in the program's customer’s zero trust posture, operational resilience, and compliance standing.

As the Deputy Chief Engineer, you will bring deep technical range across network security, endpoint, SIEM, virtualization, and cloud infrastructure, and convert that expertise into defensible architectural decisions that hold up under acquisition scrutiny, regulatory audits, and mission pressure. This is a technical leadership role. You will set direction, resolve ambiguity, and elevate the engineering capability of the team around you. Work with peers and leaders to innovate, mentor, and grow the business.

What You'll Do:

Serve as the primary technical authority for 20+ interconnected cyber engineering projects, and define the technical roadmap, engineering standards, and system architecture across multiple isolated and interconnected network fabrics.

Drive the end-to-end engineering lifecycle (design, procurement, testing, implementation, deployment, and sustainment) of next-generation cyber tools. Manage distinct engineering teams organized around Zero Trust pillars to ensure a cohesive, unified security posture.

Establish robust engineering practices for the long-term maintenance, patching, upgrading, and optimization of deployed cyber tools across all network fabrics. Establish and enforce architecture review processes, design standards, and technical debt management practices across all program workstreams

Develop and maintain the program's integrated enterprise architecture roadmap, ensuring alignment across security domains, platform layers, and operational requirements

Lead architectural trade-off analyses that weigh capability, schedule, cost, and opportunity cost, producing decision-quality artifacts for senior stakeholder consumption

Drive platform modernization roadmaps with clear sequencing logic, risk identification, and dependency mapping

Provide technical oversight across SIEM/SOAR deployment and tuning, endpoint detection and response (EDR/XDR) platforms, network segmentation and micro-segmentation architectures, and cloud and virtualization infrastructure.

Ensure interoperability and coherent design across hybrid environments including on-prem, cloud, such as IaaS/PaaS, and virtualized infrastructure stacks.

Identify and resolve integration risks early in the design cycle; engage vendors and government stakeholders on technical feasibility and alternative approaches.

Maintain situational awareness of emerging tools, frameworks, and threat intelligence relevant to the program's security mission.

Ensure all technical work products meet quality standards and are traceable to customer requirements, contract deliverables, and applicable control frameworks.

Ensure technical solutions meet ATO requirements from design through delivery — avoiding rework-intensive compliance gaps late in the delivery lifecycle.

Champion engineering rigor, documentation discipline, and a culture of continuous improvement across the program.

Lead, mentor, and develop a team of senior engineers and architects — building expertise.

Translate complex technical challenges into clear direction for engineering teams; serve as a decision-forcing function when ambiguity slows execution.

Represent the program's technical capability in executive briefings, customer engagements, and competitive positioning activities.

Join us. The world can't wait.

You Have:

5+ years of experience serving as a lead architect, chief engineer, or operator on programs of record with multi-year, multi-million-dollar scope

Experience delivering enterprise security solutions in highly regulated federal environments, such as DoD, IC, or civilian agency

Experience in delivery across at least three of the following domains: network security architecture, SIEM/SOAR, EDR/XDR, cloud security, virtualization security such as VMware, and zero trust network access (ZTNA)

Knowledge of federal contract structures, such as T&M, FFP, or CPFF and the technical implications of each model on scope, risk, and architectural decision-making

TS/SCI clearance with a polygraph

Bachelor’s degree and 10+ years of experience in cybersecurity engineering or architecture, or 12+ years of experience in cybersecurity engineering or architecture in lieu of a degree

DoD 8570 Cybersecurity Service Provider - Infrastructure Support (CSSP-IS) Certification such as CEH, CySA+, GICSP, SSCP, CHFI, CFR, Cloud+, or CND Certification

Ability to obtain a DoD 8570/8140 IAT Level III certification such as SecX, CCNP, CISA, CISSP, GCED, GCIH, or CCSP within 45 days of start date

Nice If You Have:

Experience in network security design including segmentation, NAC, secure DNS, and perimeter-to-interior trust model evolution, and security architecture frameworks such as SABSA, TOGAF, or equivalent, and their application to defense or IC programs

Experience with enterprise Security Operations Center (SOC) architecture, SIEM content engineering, and detection engineering programs

Experience in program capture support, including contributing to technical volumes, verbals preparation, or architecture demos for competitive pursuits

Knowledge of CMMC, ICD 503, DoD STIGs, and applicable IA policy frameworks

Knowledge of AI/ML applications in cyber operations and their implications for platform architecture and data pipeline design

Master's degree

Cloud security certifications such as AWS Security Specialty or Azure Security Engineer

Clearance:

Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information; TS/SCI clearance with polygraph is required.
