Job Summary:

The Senior Embedded Software Engineer is a key contributor to the development of advanced sensing technologies within the Sensing & Power Systems (SPS) business unit at Crane Aerospace & Electronics. SPS provides essential sensing capabilities, such as pressure, proximity, air data, and fluid measurement, that support critical aircraft functions across commercial and military platforms. These products must perform reliably in demanding aerospace environments, requiring robust, certifiable embedded software aligned with industry standards.

In this role, you will lead software architecture, implementation, integration, and verification activities that directly influence product performance, system safety, and long-term program success.

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 Frame Maker.
• 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.
