Engineer, Power Systems

EOS•Edison, NJ

About The Position

Eos Energy Enterprises, Inc. is accelerating the shift to American energy independence with positively ingenious solutions that transform how the world stores power. Our breakthrough Znyth™ aqueous zinc battery was designed to overcome the limitations of conventional lithium-ion technology. It is safe, scalable, efficient, sustainable, manufactured in the U.S., and the core of our innovative systems that today provides utility, industrial, and commercial customers with a proven, reliable energy storage alternative for 3 to 12-hour applications. Eos was founded in 2008 and is headquartered in Edison, New Jersey. For more information about Eos (NASDAQ: EOSE), visit eose.com. This position is accountable for independently designing and implementing cost effective electronic BMS solutions for use in battery storage. They will conduct modeling and analysis of power electronics and battery systems in grid-tied and off-grid applications. They will also design and troubleshoot circuits, produce schematics and layouts, and other duties related to electronic BMS design.

Requirements

Experience in troubleshooting, analyzing, and resolving complex electrical problems.
Experience in power electronics and power system modeling especially as related to renewable energy and battery storage systems in grid-tied, micro-grid and off-grid applications.
Experience with modelling tools like Matlab, Simulink, PSIM, PSCAD, PSSE etc.
Knowledge of DC/DC converters, DC/AC inverters with a strong emphasis on low-cost, high-performance designs for grid-tied battery systems (1500 Vdc).
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 track down board and system level 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 of 5 years of experience in electrical or electronics engineering
1-3 years of experience in power systems design required

Responsibilities

Conduct power systems modeling and analysis, load flow analysis, and other studies of the systems to determine their performance and capacity
Support battery system design and installation in the field including troubleshooting EMI, system grounding and stability issues.
Support design and development of power electronic devices (such as DC-to-DC converters, DC-to-AC inverters, AC-to-DC rectifiers and power supplies). This includes circuit board layout with high-impedance analog signals and creepage/clearances for high voltage, discrete analog and digital circuits design and simulations.
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)
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.
