Job Description:

The L3Harris Communication Systems (CS) segment Tactical Communications sector (TCOM) is seeking a highly motivated, team oriented embedded software design engineer who will be a member of a cross functional team with hands on responsibility for all phases of the software development process from requirements definition through integration and testing of completed product. Emphasis will be on cryptographic subsystem (CSS) software development. Other responsibilities will include system/software analysis, architecture definition, high-level design, detailed design, implementation, testing, documentation, and government certification of embedded software for radio or other communications products. Requires the application of the principles and techniques of computer science, engineering, and mathematical analysis. Experience with embedded C++/C, Agile Scrum, and DevOps-based software development is expected. Experience working in collaborative software design/development/test teams ranging in size from 3 to 30 engineers is desired. Experience in engineering requirements analysis, development, and testing is desired. Experience with government certification of engineering designs is also desired.

Essential Functions:

  • Research, design, develop, modify and evaluate embedded computer software for electronic equipment or other communications systems in conjunction with hardware product development.
  • Deliver the assigned portion of the entire product development cycle in an Agile Scrum environment including system/software requirements analysis, high level and detailed design, implementation, testing, integration, documentation, and government certification of embedded software designs.
  • Determine design approaches and parameters. Analyze software requirements to determine feasibility of design within time and cost constraints. Analyze equipment to establish operating data, conduct experimental tests and evaluate results.
  • Perform detailed analysis including: requirements analysis, use case scenarios, conceptual design, trade studies, test, operation, maintenance, and reliability analysis of radio communications products, internal subsystems, and external systems.
  • Perform the functional analysis, requirements allocation and technical interface definition to translate customer requirements into software development specifications for the radio and associated subsystems.
  • Develop block diagrams and interface design specifications.
  • Work with product design, test, manufacturing, logistics engineering teams, product and program management and other groups, and external customers as needed to define and execute radio product development projects and deliver high-quality radio products.
  • Prepare design and implementation reviews and oversee the configuration management and control of requirements and design documentation, and development software. Present technical briefings and status reviews.
  • Ensure the conversion of customer requirements, including informal requirements, into total systems solutions that balance the technical, schedule and cost constraints of the program.
  • Consult with electrical engineers and other engineering staff to evaluate interface between hardware and software and operational performance requirements of the overall system.
  • Develop software system testing procedures and design documentation.
  • Effective interpersonal skills, ability to convey technical matters in a clear and logical manner.

Qualifications:

  • Bachelor’s Degree and minimum 6 years of prior relevant experience. Graduate Degree and a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years of prior related experience.
  • 4+ years' experience developing and testing software developed in C or C++.
  • 4+ years' experience with OOA/OOD software development methodology.
  • 4+ years' experience in full development lifecycle for software projects.
  • 4+ years' experience producing software development documents, such as design documents and test plans.
  • Active Secret U.S. DOD Security Clearance (or inactive for less than 2 years). This position requires the candidate to already possess an active DOD Secret clearance (or a DOD Secret clearance inactive less than 2 years which can be immediately reactivated), and to maintain the clearance.

Preferred Additional Skills:

  • Experience developing bare metal software on an embedded microprocessor in C or C++.
  • Experience designing and developing device drivers.
  • Experience with UML and OOA/OOD software development methodology.
  • Experience with all phases of the software project development life cycle, including software analysis, design, development, testing (including software unit testing), and automation tools.
