We invite passionate individuals to join our team, dedicated to exceeding customer expectations through innovative and sustainable solutions.

Sensus, a Xylem brand, is seeking a Firmware Engineer to support the design, development, and ongoing engineering of Sensus metering products and systems. In this role, you will work on complex, low-level embedded firmware for high-volume, battery-operated RF Automatic Meter Infrastructure (AMI) products, balancing hands-on technical depth with system-level thinking. You will help deliver reliable, high-performance solutions that meet utility, industry, and customer requirements.

Core Responsibilities:

• Design, implement, and test embedded firmware for high-volume, battery-powered RF AMI and metering products.
• Develop and integrate firmware to support sensors, communication paths, and metrology functions within metering devices.
• Collaborate with global, cross-functional engineering and test teams to deliver factory-ready products that meet cost, schedule, performance, and quality targets.
• Develop PC-based tools and scripts (e.g., xUnit, Python, Ruby, C#) to support testing, analysis, and demonstration of product performance.
• Create and maintain documentation to support collaboration, sustainability, and internal development processes.
• Develop embedded test support, including module testing and code coverage assessment (e.g., Ceedling).
• Design test plans, fixtures, and continuous integration testing strategies for functional validation.
• Support hardware design efforts, including design calculations, circuit design, microcontroller pin assignments, and PCB schematics/layouts.
• Partner with Quality and Support teams to investigate and analyze returned or defective products.
• Interface with third-party vendors to integrate external technologies into the Sensus product portfolio.
• Participate in Xylem Watermark volunteer initiatives to support community impact efforts.

Required Qualifications:

• Bachelor of Science in Electrical Engineering or Computer Science.
• Minimum of 2 years of experience in embedded operating systems and/or embedded systems development.
• Strong experience writing and optimizing C code for microcontrollers in resource-constrained environments (memory, power, performance).
• Experience developing PC-based programs or scripts for testing and data analysis.
• Proficiency with version control systems such as Git.
• Excellent testing and troubleshooting skills, including board-level debugging.
• Hands-on experience using test equipment such as oscilloscopes, logic analyzers, and spectrum analyzers.
• Ability to work collaboratively within an engineering team while contributing technical guidance when needed.
• Demonstrated initiative for continuous improvement of firmware development processes and architecture.

Preferred Qualifications:

• Experience with utility metering products or other high-volume embedded products.
• Experience developing and debugging on MSP430 and/or ARM Cortex-M3 architectures.
• Experience writing system specifications, product requirements documents, and prototype test plans.
