With approximately 1,500 employees operating in more than 20 countries, Spectrum Safety Solutions is a global leader in fire detection and suppression solutions for high-hazard applications across verticals such as critical infrastructure, oil and gas, marine and clean energy. Our global team leverages strong customer relationships across four recognized brands, Det-Tronics, Marioff, Autronica, and Fireye, to deliver differentiated lifecycle solutions and advance growth across key segments. Carved out from Carrier’s Fire & Security business in July 2024, Spectrum Safety Solutions is now a privately-held company under the ownership of Sentinel Capital Partners.

Det-Tronics

We make the world a better place to live! At Spectrum’s Det-Tronics, we build and maintain comfortable, accessible, efficient, healthy, safe, secure, and sustainable environments. Det-Tronics is a $180M technologically innovative, projects-based global brand protecting customers in many challenging environments with high end flame and gas detection products and systems. Det-Tronics is a part of Spectrum Safety Solutions and has a global footprint with manufacturing sites in the U.S. and sales presence in all key geographies.

About This Role

The Senior Embedded Software Engineer will lead the firmware design, implementation and test aspects of New Product Development programs (NPD) and Sustaining products throughout their entire lifecycle. The chosen candidate will own the software architecture and design execution, along with processes, tools, and metrics used for new product development and on-going sustaining programs.

Key Responsibilities

• Translate high-level concepts into robust, maintainable firmware architectures.
• Capture and document requirements and rationale for regulated products to ensure traceability and compliance.
• Collaborate with hardware engineers to define and implement hardware/firmware integration strategies and diagnostic coverage.
• Work with Product Owners and stakeholders using Agile practices to maintain alignment and transparency throughout the development lifecycle.
• Adhere to and champion development processes, lead technical reviews, and implement source code that meets product requirements and complies with coding standards.
• Ensure all code is well-documented, rigorously tested, and version-controlled.
• Perform unit testing using tools such as IDEs, debuggers, emulators, communication analyzers, oscilloscopes, and logic analyzers.
• Provide work breakdown plans and task estimates to support project planning and tracking.
• Contribute to product roadmap planning, identify competency and resource gaps, and implement plans to close the gaps.
• Develop metrics to track progress and identify areas for improvement.
• Support multiple product development programs simultaneously.
• Develop and implement risk mitigation strategies throughout the firmware development lifecycle.

Required Qualifications

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• 5+ years of experience developing embedded software/firmware using C/C++.
• 2+ years of experience with Real-Time Operating Systems (RTOS).

Preferred Qualifications

• Master’s degree in Engineering, Computer Science, or a related discipline.
• Background in regulated industries (e.g., medical, industrial safety, automotive).
• Experience developing firmware for multi-core embedded processors.
• Familiarity with integrating Ethernet stacks in embedded environments.
• Skilled in using firmware debugging tools such as JTAG/SWD debuggers, oscilloscopes, logic analyzers, and protocol analyzers (e.g., UART, I2C, SPI, Ethernet).
• Proven ability to deliver firmware across the full development lifecycle - from requirements capture to design, implementation, and validation.
• Proficient in Agile development and DevOps tools such as Git, CI/CD pipelines, and automated testing frameworks.
• Experience contributing to FMEAs and implementing risk mitigation strategies in firmware.
• Strong communication and writing skills for collaboration with project stakeholders (Product Managers, Customers, and other Engineers).
• Skilled in collaborating with other engineers to distill market needs into defined technical requirements and system/subsystem/module architectures.
• Self-motivated with a proven track record of leading process improvement efforts.
