Essential Responsibilities

• Develop, maintain, and optimize embedded software in C and C++ for SPS sensing products.
• Implement firmware for signal conditioning, sensor calibration, filtering algorithms, data acquisition, and mixed-signal hardware control.
• Use additional languages and tools including Python, Assembly, and DXL.
• Create and integrate SCADE model-based designs and support auto-generated code workflows.
• Perform requirements analysis, decomposition, and traceability using IBM DOORS.
• Use IBM EWM for configuration management, change control, and workflow tracking.
• Conduct static and dynamic analysis, including structural coverage, using LDRA + TQD.
• Support certification activities consistent with DO-178C, including documentation development in Adobe FrameMaker.
• Debug hardware/software interactions using debuggers, oscilloscopes, and logic analyzers.
• Collaborate with Systems, Hardware, Test, Quality, and Manufacturing teams throughout development and verification cycles.
• Participate in peer reviews of requirements, design, code, and test artifacts.
• Lead root-cause analysis and corrective actions for software-related issues.
• Mentor early-career engineers and provide technical leadership within Integrated Product Teams (IPTs).
• Support continuous improvement of engineering practices, tools, and processes.
