Lead Model- Systems Engineer

Join to apply for the Lead Model-Based Systems Engineer role at STR

STR is hiring a Lead Model-Based Systems Engineer in our Woburn, MA office to work across a broad portfolio of DoD mission areas. Hybrid positions can at times be available, depending on the program requirements. The Systems Engineer should have experience architecting systems, working across the Systems Engineering Lifecycle, and in Digital Engineering/Model-Based Systems Engineering (MBSE) achieving architectural integrity and traceability through requirements analysis, system and software development and production system deployment.

This position offers the opportunity to work with leading domain experts in sensors development and cyber security and will incorporate MBSE tools and techniques. The ideal candidate will be well-versed in Systems Engineering techniques, Modeling and Simulation, and Digital Engineering/MBSE and be excited about opportunities to mentor more junior staff and help foster growth of subject matter expertise across the organization.

In addition to modeling in SysML, the Systems Engineer will be responsible for implementing customization and automation techniques offered by Cameo to enable multi-disciplinary programs to comply with DoD Digital Engineering goals. Proficiency in one or more high-level language (C/C++, Java, Python) is highly desired. Experience connecting SysML models with DoD simulation frameworks such as AFSIM is ideal.

The Systems Engineer should have experience implementing a rigorous MBSE approach to develop DoD systems. New programs at STR will be looking to adopt agile approaches that incorporate model-based requirements management and traceability with software development. This position is well suited for a Systems Engineer with a software development background who is interested in improving the state of the practice and demonstrating the advantages that MBSE can offer.

• Leading development programs through the Systems Engineering process using MBSE approaches that support DoD Digital Engineering goals
• Implementing rigorous MBSE approaches using SysML in Cameo (Magic Draw)
• Providing mentorship and training of Systems Engineers on the use of MBSE
• Working closely with domain experts and software development teams to realize program designs and digital engineering goals
• Implementing traceability between MBSE model content and domain‑specific analysis tools and simulation

• This position requires an Active DoD Secret Clearance with the ability to obtain a Top Secret (TS) Security Clearance, for which U.S. citizenship is needed by the U.S. Government
• BS, MS or PhD in Systems Engineering, Aerospace Engineering, or related technical field
• Minimum of 7 years experience working with SysML models in Cameo (or similar tool)
• Experience working with software‑intensive systems and open architecture

• Active Top Secret Security Clearance
• Strong experience in architecting systems using system modeling tools
• Technical Project Lead experience
• Domain expertise in one or more of the following areas is desirable:
  Radar, Electronic Warfare, Acoustic, Antenna Apertures, Sensor Resource Management, Sea/Air/Space, Large‑Scale Platform Test Systems, Cyber Physical Systems, Open System Architectures (UCI, OMS, COARPS)
• Proficiency in Java, C/C++ or Python
• Agile software development experience
• Familiarity with specific government open architectures (e.g., Open Mission Systems)
• Experience with the Advanced Framework for Simulation, Integration and Modeling (AFSIM)
