Embedded Systems Engineer III

RIX Industries is a technology-focused company specializing in the design, development and manufacturing of gas generation systems, precision compressor solutions, and cryogenic cooling technologies for critical applications in Marine, Aerospace, Land, Energy, Industrial, Medical, and Critical Infrastructure markets. Founded in 1878, the company is headquartered in Benicia, CA, and operates additional facilities in Sparks, NV.

Position Summary

The Embedded Systems Engineer III is responsible for the design, development, coding, testing, and maintenance of embedded systems and their software. Experience with both hardware and software is required. Familiarity with common PCB and PCB Assembly Industry Standards such as IPC, CE, and UL is required.

Responsibilities

• Perform schematic capture, PCB layout, component selection, bill of material generation, and produce PCB fabrication documentation.
• Design and develop digital circuitry for real time control of systems using microcontrollers, digital signal controllers, or digital signal processors.
• Design and develop digital communication interfaces such as CAN, RS232, RS485, Ethernet, SPI, or I2C.
• Design and develop analog circuitry for signal measurement and signal generation for the integration with a wide range of sensors including temperature, pressure, force, flow, concentration, current, or frequency.
• Design and develop power electronics for powering or controlling of DC-DC converters or motor drivers (<300W).
• Perform thermal analysis of PCBA componentry for component selection or identification of thermal management requirements.
• Perform complex dynamic circuit simulations for frequency response, power dissipation, or margin.
• Develop firmware and software for custom developed PCBAs to control and communicate with gas compression, gas generation, or cryogenic systems.
• Collaborate with engineers to integrate newly designed controllers into production units.
• Procure prototype quantities of components and PCBs and assemble / solder if required.
• Design and build functionally representative prototypes, both physical and computer models.
• Create test plans and procedures for the validation of new technologies.
• Perform tests using functionally appropriate prototypes and document results.
• Perform technical trade studies to support product development strategies.
• Prepare and present findings for comprehensive design reviews.
• Participate in technical problem solving for current products through cross departmental teams.
• Support Production and Supply Chain teams for production of PCBA designs through Contract Manufacturers.
• Support Test Engineering in EMC testing and qualification by designing immune and low EMI circuits or identifying necessary corrections or improvements.
• Perform Root Cause Analysis of electrical and electronic system failures.
• Design circuitry and electronic assemblies to meet regulatory standards including such as IPC, CE, UL, FCC, or MIL-Spec.
• Work with little oversight or guidance to develop products to meet requirements.
• Focus on rapid prototyping.
