Retire the ERP.

Light exists to replace factory-era ERPs with software that feels alive. Our Smart Financial Platform gives modern, global companies superpowers—automated accounting, real-time reporting, and financial flows that move at the speed of the business.

We build with our customers, ship fast, and obsess over craft. In a short time, Light has gone from idea to the operating core for leading companies like Lovable, Legora, and Keyshot. People don’t just use Light—they enjoy it.

We’re an early team defining a new software category. Think engineers who love debits and credits, designers who care about reconciliation states, and operators who treat finance as a product. If you’re excited to modernize how the world runs money—one workflow at a time—you’re in the right place.

Backed by world-class investors and advised by industry titans, we’re building category-defining products with the freedom to ship ambitiously and own outcomes.
Come help us make Light the global default for next-gen finance.

The Role

We're hiring a Technical Business Analyst to bridge the gap between product strategy and engineering execution.

Our Product Managers focus on the "what" and "why". They work with customers, define strategy, and own the roadmap. But turning that into work engineers can build requires a different skill: breaking down ambiguity, spotting gaps, writing acceptance criteria, and making sure nothing falls through the cracks.

That's you. You'll work across all our product areas, partnering with PMs and engineers to turn ideas into shippable backlog items. You'll be the person who asks "but what happens when..." before engineering has to find out the hard way.

What you'll do

  • Work with Product Managers to refine PRDs and make them engineering-ready. Identify gaps, resolve conflicts, document assumptions, and write clear acceptance criteria.

  • Break features down into well-scoped backlog items that engineers can pick up and build with confidence.

  • Work with PMs to understand customer requirements, and translate those into technical specs that account for critical edge cases and error states.

  • Join customer calls when needed to.

  • Partner with engineers to validate feasibility and refine requirements before work starts.

  • Maintain clarity on what "done" looks like for every piece of work.

You'll thrive here if...

  • You're the person who reads a spec and immediately spots what's missing.

  • You think in systems. You understand how data flows, where integrations break, and why edge cases matter.

  • You write clearly. Your acceptance criteria are testable, your assumptions are documented, and engineers trust your specs.

  • You're comfortable with ambiguity but allergic to shipping it.

  • You care about the detail without losing sight of the goal.

Your background might include

  • Business analysis, solutions architecture, or technical consulting

  • Implementation or customer success in a B2B SaaS company

  • Product or project management with a technical focus

  • Engineering or QA, with a move toward product

  • Finance operations or accounting systems implementation

Bonus points

  • Experience with fintech, accounting software, or ERP systems

  • Familiarity with API integrations, data migrations, or workflow automation

  • Comfort with SQL or reading technical documentation

  • Experience working with AI/ML-powered products

What success looks like

In your first 6 months:

  • Engineers are shipping faster because requirements are clear before work starts

  • PMs have more time for strategy because you're handling the detail layer

  • Fewer surprises in development. Edge cases are caught early, not in QA

  • You're the person both PMs and engineers want in the room when scoping new work

  • Our backlog is consistently well-defined, testable, and ready to build
