You'll work closely with engineering, supply chain, manufacturing, and external partners, learning how a global team aligns around schedules, risk, and clear communication to ship reliable hardware. We're looking for someone who's excited about a more sustainable future and wants to see, firsthand, what it takes to bring that vision to market.
Lunar Energy was founded to transition homes to 100% clean energy-making our electricity greener, our air cleaner and our energy more safe, secure and reliable for all. We're a fast-growing, global company building the world's best clean energy products to electrify all homes and connect communities to form clean, resilient virtual power plants.

- Support program schedules by tracking milestones, flagging risks, and helping communicate progress across the engineering, reliability, test, and compliance teams.
- Help build and maintain validation roadmaps, timelines, and deliverable trackers, and learn to define and track resource requirements alongside senior TPMs.
- Sit in on test and certification reviews, capture action items, and follow up to make sure issues are driven to closure with clear ownership.
- Help coordinate the ordering, shipment, and delivery of prototype validation builds, and track how build-to-build variation affects downstream test and compliance work.
- Pull together clear, executive-ready status updates that summarize risk, progress, and next steps for a program.
- Learn firsthand how program management drives a hardware product from concept through production, and how engineering, quality, and manufacturing teams work together to get there.
About you
- You're currently pursuing a BS or MS in an engineering discipline (Mechanical, Electrical, Systems, Industrial, or related).
- You're passionate about accelerating the adoption of renewables and improving our energy infrastructure, and you're excited to learn how ambitious program plans actually get executed.
- Prior internship, co-op, or project experience in an engineering or technical environment (e.g., a lab, a formula/Solar/Baja or other collegiate design team, or a research group) is a plus.
- You communicate clearly, ask good questions, and follow up until things are resolved.
- You're comfortable with ambiguity and enjoy collaborating across teams and levels in a fast-moving startup environment.
- Familiarity with tools such as Jira, Confluence, Smartsheet, or Excel is a plus, but not required - we'll teach you.

What They Do
Lunar Energy is a pioneering renewable energy startup focused on electrifying homes through innovative clean energy products and virtual power plants. The company, founded by Kunal Girotra, a former Tesla Energy executive, aims to provide scalable solutions that allow homeowners to generate, store, and manage electricity efficiently. Their flagship product is a next-generation home battery system, which is part of a modular hardware ecosystem designed to facilitate the transition to 100% clean energy by replacing fossil fuel appliances with solar-compatible technologies such as heat pumps and induction cooking (source: cbinsights.com). Additionally, Lunar Energy integrates its hardware with Gridshare software, acquired from Moixa, to enable smart energy controls and aggregation into virtual power plants (VPPs) that connect thousands of home batteries for grid balancing (source: cleantechnica.com).
Projects & Track Record
While specific completed projects are limited as Lunar Energy focuses on product development, the company has made significant strides in integrating proven technologies from its acquisition of Moixa, which has managed extensive home battery fleets for smart charging and VPPs (source: investors.sunrun.com). The first home battery system was slated for market launch in late 2022, and ongoing efforts are centered on scaling manufacturing and partnerships with Sunrun for nationwide residential rollouts. Lunar Energy's geographical operations include its headquarters in Mountain View, California, and a software hub in London, UK, targeting U.S. residential customers first while eyeing global VPP expansion (source: cbinsights.com). Key clients include Sunrun, which serves as a lead investor and distribution partner, further solidifying Lunar's position in the renewable energy market.
Recent Developments
In the past two years, Lunar Energy has not disclosed any new funding rounds or major contracts following its emergence from stealth in 2022. The company continues to focus on product scaling and commercialization of its VPP solutions, with the 2022 $300 million funding raise and the acquisition of Moixa marking significant milestones in its early development (source: equityzen.com). Although press mentions in 2025 have referenced unrelated entities, Lunar Energy remains committed to its mission of home electrification and expanding its market presence through strategic partnerships and technological advancements (source: investors.sunrun.com).
