MTSI is seeking a Senior Model-Based Systems Engineering (MBSE) Architect to serve as a technical leader supporting mission engineering, digital transformation, and enterprise architecture development for defense customers. In this role, you will lead complex system-of-systems architecture efforts, guide teams of engineers, and drive the development and implementation of digital engineering ecosystems. You will construct and analyze enterprise-level architectures and kill‑web/effects‑web constructs, support mission engineering studies, develop digital workflows, and ensure high‑quality technical deliverables across government programs.

This position requires deep experience in MBSE methodologies, SysML/UAF/DoDAF modeling, mission thread development, complex systems analysis, and coordination with senior defense stakeholders.

Responsibilities

Lead medium‑to‑large technical engineering efforts applying advanced analytical and systems engineering principles to mission‑critical challenges.
Identify technical approaches, plan system architecture development, and assign engineering resources to execute MBSE solutions.
Provide senior-level technical leadership ensuring alignment of digital engineering products to customer requirements and program objectives.
Develop, update, and maintain enterprise‑scale MBSE architectures including mission threads, METs/MTs, kill chains, and kill-web/effects-web models.
Lead the creation of system CONOPS, requirements documents, preliminary design reviews, segment-level specification reviews, and technical deliverables.
Drive adoption of digital engineering tools, environments, and hybrid cloud ecosystems to support mission engineering activities at scale.
Support mission engineering analyses by integrating modeling and simulation tools and digital artifacts into a unified environment (e.g., AFSIM).
Mentor junior and mid‑level MBSE practitioners, providing technical direction, trade study leadership, and methodological guidance.
Coordinate directly with senior government stakeholders, Joint Staff, Service Components, and Mission Integration teams to align engineering outputs with operational needs.
Ensure all digital products, architecture artifacts, and mission engineering documents are stored and maintained for reuse in digital engineering ecosystems.

Required Skills

Expertise across multiple technical domains and advanced engineering methodologies.
Ability to determine requirements, define analytic approaches, and break down highly complex problems into actionable engineering tasks.
Demonstrated ability to lead senior engineers and analysts ensuring cohesive technical outcomes.
Experience developing mission engineering threads, scenarios, and enterprise architectures.
Strong communication skills and ability to interface with stakeholders at senior echelons.

Qualifications

Bachelor’s degree in engineering or related field; Master’s preferred.
Minimum 15 years of experience in systems engineering, mission engineering, or digital engineering roles.
Extensive experience leading planning and execution of mission and systems analysis.
Experience in Systems Architecture development, kill-chain analysis, SoS architecture modeling, tradespace analysis, and M&S.
Awareness of digital thread, digital twin, and digital ecosystem concepts.
Experience coordinating engineering work with Joint Staff, Services, or warfighter elements.

Clearance

U.S. Citizenship is required.
Active TS/SCI eligibility required
Experience supporting enhanced security or classified deployment efforts is highly preferred.

Compensation

The pay range for this position is $180,000/year to $216,000/year; however, base pay offered may vary depending on established government contract ranges, job-related knowledge, skills, experience, and other factors. MTSI also offers a full range of medical, financial, and other benefits dependent on the position offered. Base pay information is based on market location. Applications will be accepted on an ongoing basis. This posting will be renewed periodically until the position is filled.
