Senior Firmware Engineer – Develop Embedded Systems for Advanced RF and Electromechanical Platforms!

Oxnard, CA | On-site

A growing engineering organization focused on advanced electronic and electromechanical systems is seeking a Senior Firmware Engineer to help design, develop, and test firmware and digital systems that support complex RF and switching platforms. This role sits at the intersection of embedded software, electronics design, and system‑level hardware integration. As a senior member of the engineering team, you will play a key role in developing microcontroller‑based firmware, designing digital hardware, and supporting the testing and validation of sophisticated electronic products.

The position requires strong hands‑on engineering capabilities, including embedded programming, hardware debugging, and lab‑based system testing. This is an excellent opportunity for an engineer who enjoys working across multiple engineering disciplines and contributing directly to the development of real hardware systems from concept through production.

We are an engineering‑driven technology company that designs and manufactures highly specialized electronic and electromechanical systems used in demanding technical applications. Our products integrate RF technologies, precision switching hardware, embedded firmware, and advanced test infrastructure. The team works in a collaborative engineering environment where firmware, hardware, mechanical, and software engineers work closely together to bring complex products from concept to production while maintaining a strong focus on performance, reliability, and quality.

• Lead the development of firmware for microcontroller‑based systems used in complex electronic platforms
• Design and implement embedded software for controllers used in RF and electromechanical systems
• Support the electrical, mechanical, and low‑level software design of new product systems
• Develop engineering prototypes based on customer specifications and product requirements
• Perform testing and validation of digital hardware and embedded systems using laboratory equipment
• Develop test procedures and execute validation activities for microcontroller hardware and digital circuits
• Create software tools and graphical interfaces used to control and test embedded systems
• Write and debug firmware for microcontrollers from vendors such as Microchip, Atmel, or similar platforms
• Develop test applications using LabVIEW or other programming environments
• Design digital circuit boards that may include microcontrollers or other embedded processors
• Support PCB layout and design activities for digital hardware systems
• Troubleshoot embedded hardware and firmware issues in microcontroller and electromechanical systems
• Evaluate electrical, mechanical, and thermal characteristics of system components during development
• Interface with contract manufacturers and production teams to resolve hardware or firmware issues
• Develop and maintain production test procedures, documentation, and equipment used during manufacturing
• Maintain and organize laboratory test equipment, tools, and development systems
• Participate in technical proposal development in response to customer requests for proposals
• Collaborate with internal teams, suppliers, and external partners to support engineering development efforts

• Bachelor’s degree in Electrical Engineering or a closely related engineering discipline
• 5+ years of experience developing firmware and embedded software for microcontroller‑based systems
• Strong experience working with microcontroller hardware and associated development environments
• Hands‑on experience testing and debugging electronic hardware and embedded systems in a laboratory environment
• Familiarity with electrical test equipment such as oscilloscopes, digital multimeters, and logic analyzers
• Experience programming in C, C++, Python, Visual Basic, assembly, or similar languages
• Ability to read and interpret electrical schematics and mechanical drawings
• Strong analytical skills and understanding of electronic, mechanical, and thermal system behavior
• Experience designing digital circuit boards…
