Job Description Summary:

The GN&C System Architecture group at Draper is seeking a Principal Systems Engineer to develop and manage requirements and interface specifications for guidance, navigation, and control (GN&C) systems in mission domains such as strategic defense systems, hypersonic and space systems, precision guided munitions, and autonomous air/sea vehicles. This role entails the application of systems engineering methods within a model-based systems engineering (MBSE) and/or digital engineering framework. Responsibilities include the elicitation of stakeholder needs, definition of use cases and operations concepts, descriptive system modeling in SysML, requirement tree development and flow-down, analysis of requirements and interfaces to define architectures and system designs, and requirements management through the product lifecycle.

Job Description:

Duties/Responsibilities
• Coordinate, schedule and participate in the requirements assessments.
• Conducts requirements engineering, scheduling, reliability, development, and evaluation, maintainability and analysis for training.
• Lead assessment effort in conducting both formal and informal evaluations and analysis.
• Independently drive solutions to complex problems - develop requirements, propose ways forward when customer requirements are unclear or incomplete, and adapt appropriately to changes in requirements.
• Sustained record of successful task leadership. Identifies risks and develops and executes mitigation strategies.
• Lead medium-sized teams. Reliably aligns team towards program goals and builds trust within the team.
• Subject Matter Expert (SME) in Systems Engineering.
• Provide insight and suggest design modifications based on analysis outcomes, and to apply analysis techniques across a range of technical challenges and disciplines.
• Identify program/system-level technical risks and develop and execute mitigation strategies.
• Develop, document, and teach best practices to less experienced engineers.

• Roles may require proficiency with modeling/simulation, computer coding languages, SysML, STPA, DOORs, and/or other engineering analysis tools
• Knowledge of GN&C, avionics architectures, fault tolerance, cyber/security, comms/encryption, or other technologies may be required as defined in the summary.

Education
Requires a bachelor's degree in engineering, physics, mathematics, or related field. Masters degree preferred.

Experience
10+ years experience in systems engineering with emphasis in requirements engineering.

Additional Job Description:

  • Elicit stakeholder needs, define concept of operations, and identify the system context to bound the problem space 
  • Work with subject-matter experts across engineering teams to define requirements and interface specifications 
  • Define expectations for verification and validation of requirements and interface specifications 
  • Analyze requirements and interfaces to define architectures and system designs 
  • Maintain traceability with higher- and lower-level specifications as well as system architecture and design work products 
  • Lead a culture of Model-Based Systems Engineering (MBSE) on Draper programs by establishing best practices and standards 
  • Lead a team developing and managing one or more requirements & interface specifications 
  • Present details of requirements & interfaces to both internal and external stakeholders
