If you’re an embedded engineer who wants your work to matter, to be seen, and to scale globally, this role offers something truly different.

Founded in 1979 and headquartered in Santa Fe, Texas, R.C. Systems LLC is a trusted leader in the design and manufacturing of gas detectors and critical alarm controllers for industrial environments where safety and precision are non-negotiable.

Our solutions protect people and assets across a wide range of industries—from fixed and temporary ambient gas detection to complex, multi-signal monitoring systems (wired and wireless). Our products are known for their reliability, performance, and ease of use, and are engineered to meet the most demanding safety and regulatory standards.

As part of the Det-Tronics family, R.C. Systems is uniquely positioned to:

• Scale innovation globally
• Expand beyond North America into new markets
• Leverage global engineering, manufacturing, and customer reach

This is a rare opportunity to join a tight-knit engineering organization with the backing and momentum of a global industrial leader.

As an Embedded Software Engineer,
located at our Santa Fe, Texas facility
, you will play a key role in the design, development, and validation of firmware across both New Product Development (NPD) and sustaining programs. You will own firmware execution end-to-end, contributing directly to products that protect lives in critical industrial environments.

You’ll collaborate closely with hardware engineers, product owners, and cross-functional partners, while working in an environment that values engineering rigor, clear documentation, and continuous improvement.

• Translate high-level product concepts into robust, maintainable firmware architectures
• Capture and document requirements and rationale for regulated safety-critical products
• Collaborate with hardware engineers on hardware/firmware integration and diagnostic strategies
• Partner with Product Owners and stakeholders to maintain alignment throughout the development lifecycle
• Champion development processes, lead technical reviews, and deliver high-quality, standards-compliant code
• Ensure firmware is well-documented, thoroughly tested, and version-controlled
• Perform unit testing using debuggers, emulators, oscilloscopes, logic analyzers, and protocol analyzers
• Develop work breakdowns and task estimates to support project planning
• Support multiple development programs simultaneously
• Identify risks early and implement firmware-level mitigation strategies

• Bachelor’s degree in Computer Engineering or a related field
• Proficiency in C

• 2+ years of experience with Real-Time Operating Systems (RTOS)
• Proficiency in C++
• Experience in regulated industries (industrial safety, medical, automotive, etc.)
• Knowledge of embedded system design and asynchronous programming
• Experience with ARM Cortex-M architectures
• Hands-on use of debugging tools (JTAG/SWD, oscilloscopes, logic analyzers)
• Familiarity with communication protocols (UART, I2C, SPI)
• Experience with Dev Ops tools (e.g., Git)
• Experience delivering firmware across the full product lifecycle
• Exposure to FMEAs and risk mitigation in firmware
• Strong communication skills and a collaborative mindset
• Self-motivated, with a passion for process improvement and engineering excellence

• 🌍 Be part of global growth—help expand products beyond North America
• 🔗 Leverage Det-Tronics’ global reach, scale, and reputation
• 🧠 Work on safety-critical technology that protects people and assets
• 🚀 Influence products from concept through launch, not just maintenance
• 👥 Collaborate with experienced engineers in a close-knit, high-impact team
• 📈 Grow your career alongside a company investing in its future

If you’re looking for more than “just another embedded role”—and want to be part of a company scaling innovation globally—this is your opportunity.
