Job description

Sierra Space Careers:

At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth.

Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond.

Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission-ready throughout space.

We are mission-driven, and together, we are an extraordinary team.

About the Role

The MBSE Model Manager contributes to the development and implementation of advanced system solutions by providing alignment, connection and direction to the technical team throughout the product development lifecycle, with primary ownership of the system model as the authoritative source of truth. The MBSE Model Manager represents the viewpoint of the integrated whole during system development and works to glue segments and subsystems together via top-down decomposition of stakeholder requirements, traceability through development artifacts, and bottom-up validation and verification of the system, all captured and maintained within the model based systems engineering (MBSE) environment. They help to shepherd the team through technical development milestones, track performance measures and identify technical risks to arrive at a compliant and cohesive system solution. The MBSE Model Manager is an emerging leader in Systems Engineering principles and is proficient in the majority of systems engineering skills including requirements management, system architecture development, concept of operation definition, system integration and system verification, with a strong emphasis on Model Based Systems Engineering (MBSE) approaches, tools, and model governance. The MBSE Model Manager may lead small teams to execute systems engineering scope and establishes modeling standards and conventions for the broader engineering team.

In this role, you will specify, architect, and integrate complex system solutions within the system model while collaborating with cross-functional teams and subject matter experts to understand project requirements and objectives. You will derive, decompose, allocate, trace, and manage system requirements and architectures within the MBSE environment, as well as define and document system concepts of operation. You will own and maintain the integrity, structure, and configuration of the system model, including managing model access, version control, and change control processes. Supporting development milestone reviews by creating model-derived artifacts and deliverables will be a key responsibility, alongside overseeing system integration and verification activities to ensure system functionality and performance. You will identify and manage technical risks, develop mitigation strategies, and contribute to continuous improvement initiatives by identifying areas for enhancement, including refining modeling standards, templates, and best practices. Adhering to established engineering processes and standards will be essential, and you will communicate effectively with team members and stakeholders to ensure project alignment and successful execution.

About You

Our mission is driven by an unyielding commitment to advancing space-based technology in service of our customers and safeguarding national security. We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower - to join us in this critical mission.

Minimum Qualifications:

• Requires Bachelor's degree in a related field (or equivalent work experience in lieu of degree or Master's +3 yrs experience).
• Typically 5+ years of related experience (or Master's + 3 years of experience).
• Emerging expertise in Systems Engineering principles and practices, including a thorough understanding of the systems development lifecycle.
• Knowledge of requirements management, functional requirements parsing, derivation, and allocation.
• Knowledge of systems architecture, systems integration, and Verification and Validation (V&V) principles.
• Hands-on experience building, structuring, and maintaining models in a Model Based Systems Engineering (MBSE) tool such as CAMEO EA, Rhapsody, or a comparable SysML modeling environment.
• Emerging ability to work and communicate with technical and specialty subject matter expert engineers to drive systems engineering products.
• The ability to obtain and maintain a Secret U.S. Security Clearance is required.

Preferred Qualifications:

• Master's degree in Engineering, Physics
