About us

The world is electrifying. As we plug in more devices and services, we need new ways to connect to power.

The traditional, one-size-fits-all utility approach, with complicated bills and frustrating customer service, no longer works. At Light, we make it easy to get affordable, renewable electricity by embedding power with the products that consumers already use, from the companies they love.

Light's mission is to power a sustainable and abundant energy future for everyone. We do it by making any company able to sell electricity. With Light's utility-as-API platform, companies from automakers and solar providers to real estate and beyond can offer their own, integrated electricity plans.

Imagine purchasing an electric vehicle that includes unlimited home charging, or solar panels that come bundled with any excess energy you might need from the grid. We're building the flexible future where clean energy shows up wherever customers already are.

We're a Series A company based in Austin, TX. We've found meaningful traction and are now investing aggressively in growth. Join us in building the digital energy infrastructure for the next century of power.

The role

As one of Light’s early engineers, you’ll build a first-of-a-kind product from the ground up. You’ll play a direct role in architecting and implementing the foundations of our platform, from our core developer API and embedded UI components to grid-facing systems like load forecasting and and behind-the-meter control.

As one of the early members of the team, you’ll help define our culture, making Light a place people come not just for the mission, but work alongside others they admire and enjoy.

You would describe yourself as having:

7+ years of software engineering experience, with a track record of delivering impactful solutions.
A high degree of product ownership, driven by objectives and outcomes, not just tasks.
Experience building robust and elegant solutions to complex problems with an understanding of what it takes to be a technical leader on significant projects.
Attention to detail and ability to execute autonomously.
Versatility in working across the stack and adaptability to evolving product needs.
Experience working at an early-stage startup is a strong plus.
The ability to work in person in Austin, TX with the founders and rest of the engineering team.

About the company

Light provides an AI-native finance and accounting platform that replaces legacy ERP for hypergrowth companies. It handles multi-entity bookkeeping, accounts payable/receivable, expenses, payments, and consolidated reporting on a ledger built for very large data volumes, all in one system. The product works by offering cloud-based accounting across multiple entities, with an integrated ledger and processes for spending, invoicing, and payments, plus connections to infrastructure partners like JP Morgan, Adyen, and BDO to support banking and operations. This differentiates Light from competitors by focusing on AI-assisted, scalable ERP replacement tailored for fast-growing firms, enabling international expansion without long, multi-month ERP projects. Light’s goal is to streamline finance operations at scale, simplify international growth for its customers, and continue expanding its platform and engineering capacity to serve more companies.

Light Phone founders on screen addiction: 'If this isn't addiction, I don't know what is

Joe Hollier and Kaiwei Tang, founders of Light, have spent over a decade promoting simplified technology. After collaborating with figures like Kendrick Lamar and Pete Davidson, they believe mainstream attitudes are shifting towards their philosophy. The company recently announced a new flip phone designed to combat smartphone addiction. In a TechCrunch podcast interview, the founders discussed how the original Motorola Razr influenced their design and addressed the growing "attention activist" movement amongst Gen Z users pushing back against Big Tech. Light Phone is opening an SDK allowing users to build their own tools, avoiding traditional app stores. The founders argue this approach helps break what they describe as pocket-sized addiction. The interview explores Light's decade-long journey and why they believe anti-smartphone sentiment is accelerating.

Light replaces fragmented finance tools with one platform: Jonathan Sanders, CEO at Light.

Light is replacing fragmented finance stacks and traditional ERPs by bringing payments, accounting and reporting into one AI-native platform. Jonathan Sanders, CEO at Light, says this shift is only possible now because AI changes how software works, moving beyond fixed SaaS tools towards “organic” systems that learn, adapt and operate more like a team member inside the company.
