The ideal candidate for the Senior Systems Engineer position is someone who has experience with full lifecycle system development. In this role, you will work closely with a talented engineering team, reporting to the Senior Manager, Systems Engineering and part of Systems team. This role is a multidisciplinary role, with significant breadth (interacting with all engineering disciplines) and depth (from customer needs to unit-level specifications). You will focus on typical Systems Engineering responsibilities, such as requirements definition management (at system, subsystem, and component levels), system architecture, system analysis, change management, interface definition, etc. Additionally, this role is a key stakeholder in integration, verification, and validation (IVV) planning and execution to ensure products meet requirements. As much as possible, a Model-Based Systems Engineering (MBSE) approach is employed to make Systems Engineering processes more thorough and efficient.
Responsibilities:
Contribute to system requirements definition and management for a product
Ensure Key Performance Parameters, as derived through mission modeling and operational analysis, are properly flowed to system requirements
Act as an interface with either existing or prospective customers to prove that customer requirements/needs are fully satisfied by system requirements
Coordinate key requirements with subsystem design teams, ensuring requirement flow-down to hardware and software subsystems is captured and properly traced
Collaborate with design engineering to ensure system architecture is properly captured in MBSE diagrams (to include Structural and Behavioral Diagrams)
Work with business development to create architectures for new solutions and applications in proposals
Maintain architectural definition throughout the development process to ensure team alignment
Develop interface control documentation and own interface management between hardware/software/firmware subsystems
Perform trade studies and quick-turn impact analyses to facilitate agile hardware/software/firmware development
Perform analysis to prove that system requirements are addressed by the system design
Ensure best practices for configuration management are adhered to
Facilitate multi-disciplinary coordination across teams
Participate in IVV planning and preparation
Contribute technical writing and figures to proposals and other business development efforts
Basic Qualifications:
BS or MS degree in Electrical Engineering, Computer Science, Aerospace, or a similar field
Minimum 5 years industry experience (or minimum 3 years of experience with an MS degree), preferably with experience spanning the entire product lifecycle (Concept to Delivery)
Demonstrated experience contributing to the establishment of a technical baseline of a system/product
Experience working with Systems Engineering tools for Requirements Management and Product Lifecycle Management (e.g. JAMA, Polarion, DOORS)
Experience working with MBSE (e.g. SparxEA, Capella)
Experience with Python development or other similar object-oriented languages
Experience working with Git/GitHub, or similar version control systems
Ability to identify gaps, prioritize in the context of the project/program, and lead an effort involving multiple engineers from other teams to resolve issues
Preferred Skills and Experience:
Experience working with RF systems (e.g. radar, comms, EW, etc.), preferably including phased arrays
Experience working in System Safety and Reliability Engineering
Good written and oral communicati ... (truncated, view full listing at source)
