Engineer, Sr, Power Electronics

EOS•Edison, NJ

2d•Hybrid

About The Position

This position is accountable for independently designing and implementing cost effective electronic BMS solutions for use in battery storage. They will design and troubleshoot circuits, conduct modeling and analysis, produce schematics and layouts, and other duties related to electronic BMS design.

Requirements

Experience in troubleshooting, analyzing, and resolving complex electrical problems.
Expertise in designing DC/DC converters, DC/AC inverters with a strong emphasis on low-cost, high-performance designs for battery systems
Experience with design, specification, and procuring of electrical equipment and systems. i.e., switchgear, motors, heat tracing, UPS, batteries, cathodic protection, motor operated valves, transformers, breakers, relays, temporary generators.
Thorough understanding of electrical theory and electronics design under both the digital and analog domains
Ability to design and layout electrical circuit boards, follow IPC and other safety design standards using Altium, KiCad.
Working knowledge of embedded control systems and their applications.
Familiarity with design for EMC and availability to trace down EMI issues.
Awareness of safety certification process to standards such as UL.
Knowledge of communications protocols such as TCP/IP, CAN, i²C and SPI, specifically Modbus
Strong cross-disciplinary system design skills.
Capability to select and integrate off-the-shelf component and equipment.
Integrate with a greater team and understand how components fit together into larger systems.
Understanding of hardware and design requirements of all components and product as a whole.
Strong sense of ownership, initiative, and ability to follow through on objectives.
Bachelor's degree in electrical engineering required.
Minimum 8 years' experience.

Responsibilities

Circuit board layout with high-impedance analog signals and creepage/clearances for high voltage.
Discrete analog and digital circuits design and simulations.
Provide first principle techno-economic modeling to help define the dimensions and electrical configuration of battery string control. Capture impacts from shunt currents, current collector losses, as well as trading bussing and switching efficiency with BMS costs.
Design and develop power electronic devices (such as DC-to-DC converters, DC-to-AC inverters, AC-to-DC rectifiers and power supplies)
Work on electronic designs (schematics), component sizing and theoretical analysis to study the worst cases scenarios and thus consider all the potential stress experienced by the components (stress tests)
Conduct power systems modeling and analysis, load flow analysis, and other studies of the systems to determine their performance and capacity
Produce detailed engineering materials including design schematics, PCB layouts, tolerance analysis, design notes, FMEA, failure analysis reports, and technical review documents.
Verification testing of electronic components and overall product designs.
Provide maintenance of power systems application functionality, including documentation and user interfaces
Design to meet safety certification standards, such as UL and IEC.
Coordinate and manage vendor, supplier, and contractor relationships for prototype design.
Provide technical guidance to engineering personnel, manufacturing, and field operations.
Other duties, responsibilities and activities may change or be assigned at any time with or without notice, in the spirit of an agile design group within an active technology company.
