Model Based System Engineer

LMI is seeking a Senior Model-Based Systems Engineer (MBSE) with deep expertise in SysML to support the development and representation of future space architectures, with a focus on sustained space maneuver and resilient orbital operations.

In this role, you will lead the creation of Model-Based Systems Engineering (MBSE) artifacts in SysML that translate conceptual architectures and analytical results into structured, interoperable system models. These models will support early-phase force design, architecture evaluation, and integration with external tools and analytical environments.

This position is ideal for a systems engineer who can operate in ambiguous, concept-driven environments, and who excels at turning evolving ideas into coherent, defensible system models that inform decision-making.

This is an on-site role in Colorado Springs, CO and requires an active TS/SCI or TS with SCI eligibility clearance and a willingness to obtain a CI Poly.

LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed.

Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government, efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors—helping agencies navigate complexity and outpace change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value.
