Scully Signal Company, the leader in safety systems, is an engineering and manufacturing company established in 1936. Our products are an industry standard for controlling hazardous fluid transfers, eliminating spills, and thereby providing a safe environment for the personnel, facilities, and infrastructure involved in those operations.

With our strong focus on quality, reliability, technology development, excellence in engineering, and in-house manufacturing, we are uniquely positioned to take our product lines to the next level of functionality and user experience.

Scully’s core systems include—but are not limited to—overfill prevention, static ground proving, retained product monitoring, water detection, vehicle identification and communication, and fluid delivery systems.

Software-controlled systems will be a key component in expanding our product line, ensuring the safety and reliability of our fluid transfer solutions, and growing our company. If you are an experienced firmware engineer, this is a unique opportunity to champion the future of embedded systems at Scully.

What is expected from you:

• Work closely with system architects, electrical and compliance engineers to develop high-quality C code in a real-time embedded environment.
• Design, implement, and document firmware, peripherals drivers, control algorithms, software libraries, test scripts, and other components as integral parts of larger microcontroller-based applications.
• Develop embedded system architectures and support proof of concept activities.
• Work with electrical engineers to bring up and debug new hardware.
• Write and review design and specification documents and participate in code reviews.
• Support our in-house quality and manufacturing teams, as well as our customer-facing applications teams, in troubleshooting test equipment and legacy product firmware/software.
• This is an on-site role as there is a need to interact daily with members of the engineering and other in-house departments.

Your background:

• BS or higher in Computer Science or Electrical Engineering, with practical engineering experience.
• 6 years of experience in developing embedded code in a product development environment.
• Strong proficiency in C, familiarity with C++.
• Strong knowledge of ARM or PIC based architectures and bus protocols: UART, ADC, SPI, CAN, I2C, One Wire.
• Strong technical experience in developing, integrating, building, and testing complex bare-metal and multi-threaded embedded applications, including wireless communication solutions such as BLE, Wi-Fi, and NFC.
• Experience with RTOS and working knowledge of Linux OS.
• Strong writing skills for supporting SIL documentation and UML.
• Strong software fundamentals including architecture design, algorithm development, data structures, code modularity, and maintainability.
• Experience with Software Configuration Management and Defect Tracking Tools like Git, JIRA, or comparable.
• Strong understanding of electronic circuits for troubleshooting and bringing up circuit boards during product development.
• Must be comfortable with hands-on lab work (using scopes/logic analyzers, soldering irons, etc.) to support integration.
