About Eos Energy Enterprises
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.
About the Role
This role sits at the intersection of Eos's battery system design and its real-world deployment, closing the loop between how our BESS is engineered and how it is actually built, commissioned, and serviced in the field. The Engineer, Product Serviceability & Field Reliability will translate field failure data, commissioning friction, and O&M feedback into concrete product design inputs — while equipping Field Services and EPC partners with the technical standards, diagnostics, and documentation needed to service Eos systems efficiently and safely.
Responsibilities
Serve as the primary technical liaison between Product Engineering and Field Services/execution, ensuring design decisions account for constructability, commissioning sequencing, and long-term serviceability.
Support Field Quality team lead root cause analysis (RCA) on field-reported hardware/firmware failures and translate findings into design change requests, retrofit specs, or service bulletins.
Build and maintain or support SQL-based fleet telemetry monitoring to flag precursor failure signatures across deployed Eos systems, and use Python for diagnostic scripting and trend analysis.
Author and maintain technical due diligence standards and field-readiness documentation used by EPC partners, Field Services, and internal stakeholders.
Identify and resolve thermal, mechanical, and power-delivery bottlenecks that impact serviceability, commissioning timelines, or asset reliability.
Partner with Commissioning and Field Services teams to reduce time-to-resolution on site issues by improving diagnostic tooling, spare parts logic, and troubleshooting documentation.
Support RFP and pre-sale technical due diligence by providing serviceability and reliability input on proposed system designs.
Contribute to fleet-wide uptime KPIs and report data-driven reliability trends to Deployment leadership.
Education and Experience
5+ years in utility-scale BESS or related power systems, with direct experience bridging OEM/product engineering and EPC/field execution.
Demonstrated experience in performance testing, capacity validation, or commissioning of megawatt-scale energy storage systems.
Strong root cause analysis background across hardware/firmware failure modes.
Proficiency in SQL for fleet telemetry monitoring and Python for diagnostic/data analysis.
Experience authoring technical standards or due diligence documentation used cross-functionally.
M.S. in Engineering (or equivalent experience); specialization in sustainable energy systems a plus.
Comfortable operating in ambiguity at a growth-stage OEM, translating field-level signal into upstream design action.

Working Conditions
Office Environment - Must be able to remain in a stationary position 50% of the time and occasionally move about inside the office to access file cabinets, office machinery, etc. Required to have close visual acuity to perform an activity such as: preparing and analyzing data and figures; transcribing; viewing a computer terminal; extensive reading. May be required to exert up to 25 pounds of force occasionally to lift, carry, push, pull or otherwise move objects, including the human body.
Customer/Partner Locations – Employee may visit customer or partner locations that may be comprised of office, manufacturing floor, laboratory environments and construction sites depending on the location and reason for visit.

Product Engineer Jobs in New Jersey: Frequently Asked Questions
How do you become a product engineer in New Jersey?
Most product engineer roles in New Jersey require a bachelor's degree in an engineering discipline such as mechanical, electrical, or industrial engineering. New Jersey does not mandate a state-issued professional engineer license for most private-sector product engineering positions, though a Professional Engineer credential from the New Jersey State Board of Professional Engineers and Land Surveyors strengthens candidacy for senior or regulated roles. Employers in pharma and defense often add industry-specific certifications as a preference.
Which companies hire product engineers in New Jersey?
Employers hiring product engineers in New Jersey right now include KLA, Speechify, and Construction Specialties, based on current listings on Migrate Mate as of August 2026. New Jersey's concentration of pharmaceutical headquarters, defense contractors, and consumer goods manufacturers makes it one of the more consistently active states for product engineering openings.
Which New Jersey cities have the most product engineer jobs?
The cities with the most product engineer openings in New Jersey are Totowa, Princeton, and Lebanon. This distribution reflects the dense cluster of pharmaceutical and life sciences campuses around central Jersey, the corporate headquarters anchored in the Newark metro, and the defense and industrial manufacturers concentrated in the northern and southwestern corridors of the state.
Are there remote product engineer jobs in New Jersey?
Yes, but they're less common than in purely software-focused fields, since product engineering often requires hands-on lab, prototyping, or manufacturing floor access. About 38% of product engineer openings tied to New Jersey are remote or hybrid as of August 2026. The portions of the role most likely to be performed remotely include requirements gathering, documentation, and cross-functional coordination.
How can I get hired as a product engineer in New Jersey with little or no experience?
The most realistic entry path is a new-graduate or associate engineer program at one of New Jersey's large manufacturers or pharmaceutical companies, many of which run structured rotational programs for engineering graduates. Lateral moves from quality technician, manufacturing engineer, or test engineer roles are common doors into product engineering. Building a portfolio with senior design project work, internship output, or a professional engineer exam result from the New Jersey State Board adds meaningful credibility when applying without full professional experience.
Where can I find and apply to product engineer jobs in New Jersey?
You can find and apply to product engineer jobs in New Jersey on Migrate Mate, which lists current openings across the state. Search the listings for roles that match your experience level and preferred location, then apply directly to the ones that fit.
