Software Systems Engineer, Safety Critical Embedded Systems

Forterra is hiring a Software Systems Engineer to define and integrate requirements, architecture, interfaces, and verification for safety-critical embedded software supporting autonomous ground vehicles. The role connects operational and safety needs to implementation and works across software, systems, test, and safety engineering to maintain requirements traceability and verification evidence.

Responsibilities:

• Derive, refine, and maintain system and software requirements for safety critical embedded functions
• Break system functions into implementable software responsibilities and support functional allocation across system elements
• Define interfaces, data flows, operating modes, fault behavior, and assumptions for embedded software components
• Maintain the relationship between hazards, safety goals, mitigations, requirements, architecture, and verification evidence through requirements traceability
• Review software and system designs for completeness, consistency, testability, diagnosability, and safe behavior under faults and abnormal conditions
• Work with software and test engineers to establish verification methods, resolve requirement issues, and assess coverage and evidence
• Support architecture reviews, requirements reviews, technical baseline reviews, integration reviews, and customer reviews with clear technical analysis and documentation
• Work across development, test, safety, and program teams to resolve cross component issues and maintain a reusable platform baseline

Requirements:

• Bachelor's degree in Systems Engineering, Computer Engineering, Electrical Engineering, Computer Science, or a related field. Equivalent experience may be considered
• Five or more years of systems engineering experience with complex embedded, autonomous, automotive, aerospace, defense, or industrial systems
• Hands on experience developing and managing system or software requirements, including requirements traceability and clear verification criteria
• Experience with functional decomposition, allocation, interface definition, and architecture development for embedded systems
• Working technical knowledge of embedded software, including C or C++, RTOS concepts, communications, and hardware and software interfaces
• Experience using requirements or architecture tools such as Jama, DOORS, SysML, UML, or comparable tools
• Familiarity with verification planning, integration, anomaly resolution, and technical evidence for customer or program reviews
• Strong analytical, written, and verbal communication skills, with the ability to explain complex technical relationships clearly
• This position may require eligibility to obtain and maintain a U.S. security clearance
• Experience applying safety critical development and assurance standards such as MIL-STD-882E, JSSSEH,JS-SSA-IG, ISO 26262, IEC 61508, or DO-178C
• Experience with hazard analysis and safety engineering activities such as FHA, STPA, functional allocation, mitigation analysis, or safety case development
• Experience defining interfaces and behavior for vehicle networks, diagnostics, fault management, orsafety monitoring functions
• Understanding of robotics domains such as motion control, planning, perception, localization, vehicle dynamics, and platform integration
• Experience working across multiple vehicle variants or programs while maintaining a reusable technical baseline
• Experience providing technical leadership through architecture reviews, requirements workshops, mentoring, or cross functional integration
