Job description
Exowatt is revolutionizing the energy landscape for the AI era with our groundbreaking P3 system that captures solar energy, stores it as heat, and generates electricity on demand. Founded in 2023 and backed by leading investors including Andreessen Horowitz, Sam Altman, and Felicis, we're committed to providing clean, modular, and scalable power that meets the rapidly growing demands of AI infrastructure. Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.
We're looking for an Electrical Engineer to contribute to the design and development of the electrical systems that make our technology work - from power conversion and controls to instrumentation and grid interconnection. This is a hands-on individual contributor role focused on technical execution. You'll own discrete electrical designs and sub-systems, work closely with senior engineers on broader architecture decisions, and partner across mechanical, controls, and systems teams to bring our product to life.
This role is based at our headquarters in Miami, FL, but it could also be in our Austin, TX location. In either case, relocation is required, and relocation assistance will be provided.
Key Responsibilities
- Design and develop electrical components and sub-systems for thermal battery and power dispatch applications
- Create schematics, PCB layouts, and technical specifications under the guidance of senior engineers and system architects
- Perform electrical analysis, simulation, and validation testing on assigned designs
- Contribute to the design of power electronics, control circuits, instrumentation, and protection systems
- Work closely with mechanical, software, and systems engineering teammates to integrate electrical designs into the broader product
- Troubleshoot electrical issues during prototype builds, bench testing, and field deployments
- Evaluate components and vendor technologies; make recommendations on part selection
- Ensure designs meet applicable safety standards, regulatory requirements, and internal performance targets
- Document designs, test procedures, and technical findings clearly
- Support prototype builds, bring-up, and field testing activities
- Keep current on developments in power electronics, grid integration, and renewable energy systems
Required Qualifications
- Bachelor's degree in Electrical Engineering or related field
- 3+ years of electrical engineering experience, ideally with exposure to power systems or power electronics
- Working knowledge of power electronics, circuit design, and control systems
- Proficiency with electrical design tools (Altium, EAGLE, KiCad, or similar)
- Familiarity with simulation tools (SPICE, MATLAB, or similar)
- Understanding of relevant standards (NEC, UL, IEC, IEEE)
- Strong analytical and problem-solving skills
- Clear technical documentation and communication
Preferred Qualifications
- Experience with high-voltage or high-power electrical systems
- Exposure to renewable energy applications (solar inverters, BMS, grid interconnection)
- Hands-on prototype and field-testing experience
What We Offer:
- Competitive salary and equity options.
- Comprehensive benefits package, including health, dental, and retirement plans.
- A dynamic work environment that fosters creativity and innovation.
- Opportunities for professional growth and development in a rapidly evolving industry.
- Relocation assistance.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.

What They Do
Exowatt develops modular, transportable power systems specifically designed to meet the demanding energy needs of AI data centers and other high-load customers. Their flagship product, the Exowatt P3, captures solar energy and stores it as high-temperature heat, which is then converted into dispatchable electricity on demand, enabling 24-hour renewable power availability (source: exowatt.com). This technology aims to reduce reliance on conventional grid power by providing a reliable, renewable energy source tailored for AI infrastructure, commercial, government, and off-grid applications (source: exowatt.com). The company emphasizes modularity and dispatchability, targeting frontier land data centers that require rapid access to large amounts of power, positioning itself as a critical enabler for the future of AI and energy-intensive industries (source: wikipedia.org).
Projects & Track Record
As a young company, Exowatt's project portfolio is in the early stages, focusing primarily on deployment planning rather than completed large-scale projects (source: wikipedia.org). The company announced in April 2025 that its $70 million Series A funding would support commercial deployments starting that year (source: exowatt.com). While no public list of completed projects with specific capacities or commissioning dates is available, Exowatt’s focus remains on AI-scale data centers and other large-load customers (source: exowatt.com). The company has attracted significant backing from prominent venture and strategic investors including a16z, Atomic, Felicis, Sam Altman, HSBC Innovation Banking, and others, underscoring confidence in its technology and market potential (source: refreshmiami.com).
Recent Developments
In April 2025, Exowatt closed a $70 million Series A funding round, split evenly between $35 million in equity and $35 million in debt, bringing total funding to $90 million at that time (source: exowatt.com). This round was led by Felicis and included HSBC Innovation Banking among other lending partners, with prior seed investments from a16z, Atomic, and Sam Altman (source: refreshmiami.com). Coverage in 2025 highlighted Exowatt’s emergence from stealth mode, its dedicated focus on AI data-center power solutions, and rapid team growth from approximately 25 employees toward a larger engineering organization based in Miami (source: refreshmiami.com). By 2026, the company had expanded to roughly 90 employees and secured total funding of $105 million across five rounds (source: tracxn.com).
Working There
Exowatt hires across a range of roles focused on hardware engineering, product development, operations, manufacturing, and deployment support, reflecting its identity as a deep-tech hardware startup rather than a software-only company (source: refreshmiami.com). The company’s growth strategy centers on leveraging Miami-based talent, with the primary office located in Miami, Florida (source: exowatt.com). Public materials and case studies highlight a focus on systems development, product storytelling, and deployment-oriented work, indicating a collaborative environment for engineers and startup builders (source: wheelhouse.io). While detailed benefits and role-specific hiring information are not publicly documented, the company’s visible hiring profile suggests opportunities in mechanical and electrical engineering, product management, and operational roles (source: exowatt.com).
