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 Fuse Energy.
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 modernise how companies run money, you're in the right place.
Backed by world-class investors including Balderton and Atomico 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.
About the Role
You'll sit at the heart of our Customer function and work with our most important customers. You’ll make sure they understand the value Light brings them and drive renewals and upsell.
Your customers are Financial Controllers, Finance Directors and CFOs at fast-growing multinational SaaS and tech companies. Senior, technical, time-poor. They expect you to keep up, to tell them straight when something won't work, and to make their team the hero.
We’re a young company, and we’re just starting to renew contracts. In parallel, we’re deploying Agentic Customer Engineers who help our customers make the most of Light. While they re-design customer workflows and deploy agents, you’ll own the stakeholders, the adoption, and the commercial in this motion. There's no set playbook yet. You'll write it, and we'll help.
Key Responsibilities
Own existing customer relationships and drive adoption, renewal and upsell
Ensure that Controllers, Finance Directors, and CFOs see the value Light brings
Make finance the hero - help them do their best work and get recognition for it
Partner two-in-a-box with Agentic Customer Engineers to help customers make the most of Light and our suite of AI agents
Spot an engagement going sideways before the customer does, and fix it
Feed what you learn back into the playbook the team is building
Experience & Qualifications
5+ years owning customers in account management, customer success, consulting, or a commercial delivery role - with outcomes you can point to
You hold your own with a CFO. You can talk multi-entity finance, ROI, and adoption without flinching, and you know when to push back
You've driven adoption and expansion, not just kept accounts warm and sent QBRs
You bring structure to messy, ambiguous engagements - clear plans, sharp prioritisation, and the judgement to know which details matter
You've owned accounts and driven outcomes
You use AI tools daily and have specific opinions on where they help and where they don't
Fluent English; additional European languages a plus
Bonus #1: Finance or accounting background
Bonus #2: Experience in a forward-deployed, solutions-led, or professional-services model focused on renewals and upsell, ideally in the context of AI
You'll probably struggle here if
You need a big support team, a mature playbook, and a manager on call to operate - this is a founding role with limited scaffolding
You can't give a concrete example of telling a senior customer "no" and making it stick
You love the status quo - this job is about change more than maintenance
You've used ChatGPT once and weren't impressed - we go all in on AI at Light
The good stuff
In addition to being part of a great team and working in a really fun and innovative environment, we offer:
💸 A competitive salary + potential stock options
🏝 Generous package of paid annual leave + public holidays
🥳 Regular socials and company off-sites (last time was in Piemonte, next time is in Provence)
🚀 A huge opportunity for career growth as you'll help shape a market-defining motion
The famous last words
Working at Light means you're embarking on an exciting journey to reshape the future of multinational financial operations. Our cheat-code is that we've built something like this before - and are now doing it again, only better. Our goal is to make global finance effortless and empower companies to make informed decisions.
