Approximately 3,000 employees worldwide (source: salestools.io). Revenue of $1.3 billion (source: cbinsights.com).
What They Do
Enphase Energy focuses its core technology on solar energy through semiconductor-based microinverters that convert DC power from individual solar modules to AC at the panel level. This innovative approach is integrated with proprietary networking and software for monitoring and control, as well as battery storage solutions like IQ Batteries and electric vehicle chargers. These technologies enable the generation, use, storage, and sharing of solar power, making Enphase a leader in the solar energy sector (source: cbinsights.com). Their product lineup includes microinverters compatible with virtually every solar panel, AC modules, and award-winning smart batteries such as the IQ Battery 5P. Additionally, they offer a leading mobile app for real-time energy data, control, and payment for excess power shared with communities, forming the Enphase Energy System for residential and commercial solar-plus-storage setups (source: enphase.com). Target markets encompass residential homeowners and commercial sectors in the United States and internationally, prioritizing clean energy solutions for self-consumption, grid interaction, and energy independence (source: cbinsights.com). Enphase holds a competitive position as a leader in microinverter-based solar technology, differentiating through module-level power conversion for higher reliability and scalability over traditional string inverters (source: enphase.com).
Projects & Track Record
Enphase Energy has a significant track record with over 5 million deployed systems globally and more than 84.8 million microinverters shipped since its inception in 2006 (source: enphase.com). While specific named projects with capacities, locations, or costs are not publicly detailed, the company's scale implies extensive involvement in residential and commercial solar-plus-storage deployments. Key clients include residential users and commercial entities adopting solar self-generation, with partnerships evident in utility interactions, although no major clients are specifically named (source: cbinsights.com). Enphase's geographic presence spans over 160 countries, with a strong focus on the U.S. market, particularly in California, where it continues to expand its operations (source: enphase.com).
Recent Developments
In the last two years, Enphase has announced increased deployments of its Legacy NEM System Expansion Solution in California, where utilities have streamlined approvals for expanding existing solar systems under net energy metering rules (source: zoominfo.com). On February 11, 2025, the company launched the expanded IQ Battery 5P solution tailored for new home projects in California, enhancing storage capabilities for residential solar setups (source: zoominfo.com). While no major acquisitions or mergers have been reported post-IPO, the company continues to focus on product milestones, including a patent grant for a piezoelectric power converter with trajectory control related to photovoltaics and power supplies (source: cbinsights.com).
Working There
Enphase offers a variety of roles across key departments at its Fremont headquarters, including engineering, product management, sales and marketing, and operations. Specific roles include software development, hardware design, business development, and customer success, with leadership positions such as Chief Executive Officer & President and specialized roles like Director of Cloud and IoT (source: salestools.io). The company culture emphasizes innovation, collaboration, continuous learning, and employee well-being, which is reflected in the amenities at their headquarters, such as open-plan offices, collaboration spaces, fitness centers, and wellness rooms designed to foster teamwork and attract top talent (source: salestools.io).

Join our dynamic team designing and developing next-gen energy technologies and help drive a sustainable future!
About the role
This position sits within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. Our team is responsible for defining and delivering the next-generation power module, with higher power density to reduce footprint and thermal load. We're looking for a technically deep power electronics engineer focused on increasing efficiency while reducing cost per watt.
What You Will Do
- Design and develop power conversion circuits and magnetics for the SST platform, optimizing for power density, efficiency, and thermal performance
- Evaluate and integrate advanced power semiconductor devices (particularly, GaN) and planar magnetics to increase power throughput while shrinking module footprint
- Translate modeling and simulation results into benchtop prototypes, and reconcile differences between predicted and measured performance
- Drive design trade-offs across power density, efficiency, thermal management, and cost per watt to meet next-generation product targets
- Co-design with mechanical and thermal engineering to jointly optimize packaging, cooling, and power density, and collaborate with controls engineering to integrate power modules into the SST platform
- Lead root-cause analysis and design iteration based on test data to continuously improve power density and reliability
Who You Are And What You Bring
- M.S. or Ph.D. in Electrical Engineering
- 4+ years of nonacademic experience for Ph.D. candidates (6+ years for M.S. candidates), with greater experience expected for Senior Staff-level candidates
- Hands-on experience in designing power electronics, particularly if focused on power density
- Ability to translate modeling and simulation to benchtop performance and be able to reconcile differences between theory and practice
- Familiarity with advanced power semiconductor devices and magnetics (particularly planar transformers)
- Experience co-designing power electronics with mechanical and thermal engineering teams, balancing electrical performance against packaging and cooling constraints
- Ability to lead technical execution of significant power electronics designs with a high degree of autonomy, escalating major trade-offs as needed
- Experience mentoring less experienced engineers and contributing to technical design reviews within the team
