Overview

We are seeking a Modular Open System Approach (MOSA) Architect & Systems Integration Lead for a critical Army portfolio to advise on strategy, policy, technical, and programmatic dimensions of MOSA implementation across the Army. This role is not just about compliance; it is about engineering lethality and flexibility in the next generation of Army systems. You will leverage Model-Based Systems Engineering (MBSE) and digital thread integration to define the logical boundaries and interfaces that allow the Army to swap components rapidly without vendor lock-in, helping ensure system architectures are interoperable, interchangeable, and ready for multi-domain operations.

This is not a compliance or documentation role. The right candidate understands why MOSA succeeds or fails in practice and the gap between well-intentioned policy and real acquisition behavior and can operate credibly with senior leaders, program managers, engineers, contracting professions, and Industry. The advisor will help translate emerging MOSA policy into implementable guidance, governance, and practice; diagnose and address the organizational, technical, contractual, and cultural barriers to adoption; and drive genuine buy-in across a community where "MOSA" means many things to many people. The advisor may provide technical direction to developmental personnel supporting MOSA workstreams, or directly execute portions of those efforts, depending on priorities.

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.

Responsibilities

Advise the Army MOSA lead on strategy, policy translation, and implementation across the acquisition enterprise.
• Diagnose barriers to MOSA adoption and develop practical, low-bureaucracy approaches to overcome them.
• Support development of implementation guidance, governance frameworks, seam/architecture management practices, modular contracting approaches, and data/module-description standards.
• Translate senior-level policy intent into actionable guidance for the acquisition community - and translate program-level realities back up to inform policy.
• Build and sustain buy-in across Government and Industry through credible, two-sided engagement.
• Provide technical direction to developmental personnel supporting MOSA workstreams as needed.
• Translate complex Army requirements into modular solutions using SysML. Develop model libraries and profiles to serve as the Authoritative Source of Truth for system-of-systems.
• Identify logical boundaries and system interfaces to enable seamless component interchangeability.
• Apply open standards (e.g., SOSA, DoDAF, and UAF) to practical hardware/software builds. Draft and refine DoD systems engineering guidance and technical criteria for MOSA implementation across Programs of Record.
• Design and manage digital threads, integrating MBSE with Product Lifecycle Management and DevSecOps stacks.
• Conduct trade-off studies and "what-if" assessments to balance modularity benefits against rapid deployment needs; defend MOSA business cases for milestone decisions.
• Support the development of technical assessment frameworks and performance metrics to evaluate MOSA compliance throughout the systems engineering V-model.
• Facilitate or engage in technical exchange meetings, potentially with various PAEs to drive digital convergence.

Qualifications

Required Qualifications

• BS/MS in Systems, Electrical, or Computer Engineering (or equivalent technical industry experience).
• 10+ years in Systems Engineering or Data Architecture with a focus on Architecture Patterns (Microservices, SOA, REST).
• Ability to lead the development of innovative approaches in modernizing systems engineering practices.
• Deep familiarity with ISO/IEC 15288 and DoD 5000 series acquisition policies.
• Proven ability to integrate requirements management with architectural models to ensure end-to-end traceability.
• Experience advising data rights strategies to ensure long-term competitive sourcing and avoid vendor lock-in.
• Knowledge of conformance tools and verification suites to ensure modularity throughout the Systems Engineering V-model.
• Experience with MBSE tools (e.g., No Magic Cameo, IBM Rational Rhapsody, Sparx Enterprise Architect).
• Understands MOSA as a means to acquisition freedom and warfighting advantage - not a compliance exercise - and can articulate first principles to skeptical audiences.
• Understands why buy-in is hard - the incentive misalignments, business-model tensions, technical trade-offs, and cultural inertia that cause MOSA to stall or become paper compliance.
• Has enough technical and programmatic grounding to know when a modular boundary is real versus theoretical, and to engage credibly on architecture, interfaces, data rights, integration, and acquisition strategy.
• Familiarity with both acquisition strategy/policy and the technical/programmatic realities of execution with the ability to move between them credibly.
• A practical understanding of MOSA principles and the real-world barriers to their adoption.
• Working knowledge of DoD/Army acquisition and contracting fundamentals, including data rights and IP considerations.
• Ability to influence and build consensus among senior leaders, technical experts, and Industry.
• Strong communication skills across audiences, from senior leaders to working-level engineers.
• Sound judgment and comfort operating with ambiguity in a rapidly changing environment.
• Ability to make suggestions on next steps and tasks without.
• Active Secret.

Desirable Qualifications

• Experience implementing - not merely documenting - MOSA or open-architecture approaches.
• Exposure to the failure modes of open-systems efforts (paper compliance, lock-in, misaligned incentives) and how they can be overcome.
• Perspective on both the Government and Industry sides of acquisition.
• Familiarity with digital engineering, reference architectures, open-architecture standards, and data/interface management.

Location

• Hybrid or Remote. Hybrid if less than 40 miles from Aberdeen Proving Ground or Crystal City.

Clearance

• Cleared Secret.

Target salary range: $123,000 - $185,000.

The salary range displayed represents the typical salary range for this position and is not a guarantee of compensation. Individual salaries are determined by various factors including, but not limited to location, internal equity, business considerations, client contract requirements, and candidate qualifications, such as education, experience, skills, and security clearances.
