Product Manager

PRODUCT MANAGER, LEAD TO CASH Location: London, onsite 5 days a week 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. We’re an early team defining a new software category. If you’re excited to modernise how the world runs money, one agentic 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. ABOUT THE ROLE This is a hands-on product role reporting to the VP of Product Development. You’ll own Lead to Cash: everything between a signed deal and cash in the bank. That covers contracts, billing and invoicing, revenue recognition, payments, and credit control. You’ll set the roadmap for the area with the VP, and your discovery and judgement decide what actually ships. In Lead to Cash, the ledger has to keep up with whatever commercial terms each customer signs. A contract changes mid-term, and the invoices, deferred revenue and reporting all have to follow. A parent company wants one bill for a dozen subsidiaries. A customer’s Stripe setup doesn’t match how they actually sell. Every customer bills a little differently, and the product has to absorb those differences without turning into a pile of one-offs. You work out which problems are patterns worth building for and which aren’t, and you say so. Your stakeholders are engineers, designers, Sales, Solutions Engineering, Implementation, and the Financial Controllers, Finance Directors and CFOs who run their revenue on Light. Most of them are senior, technical and short of time. They expect you to keep up, and to be honest with them when a request would cost more than it’s worth. KEY RESPONSIBILITIES - Own the Lead to Cash roadmap and its delivery, from discovery to go-live, and the metrics that show whether it’s working for customers - Turn contract terms, pricing models and revenue recognition rules into product requirements engineers can build from - Decide which customer requests become product and which don’t, and bring a clear recommendation to the VP of Product Development when the call is a big one - Lead discovery with finance teams: sit with them through a billing run or a month-end close and find what’s slow, manual or wrong - Work with Sales and Solutions Engineering on what gets promised to customers, before it’s promised - Sequence delivery with Engineering and Design without cutting the corners that matter in finance - Own the integrations that feed Lead to Cash, such as CRMs and payment providers, with clear scope for each - Spot a release going off-track before it slips, and escalate or intervene early - Enable the teams downstream of you (Sales, SE, Implementation, Support) to sell, set up and support every Lead to Cash feature from day one - Shape how AI agents run billing and collections work, inside policies that finance teams set and can audit EXPERIENCE & QUALIFICATIONS* We’re looking for someone with around 4–8 years in product (or equivalent experience), who brings: - You ship product, not slideware. You’ve owned real features that real users depend on. You measure yourself by what went live and what it changed, not by the roadmap you maintained. This is the non-negotiable. - You turn accounting rules into product. You can read IFRS 15 or ASC 606, a customer’s master services agreement, or a messy pricing sheet and work out what the product has to do. You know why a mid-term upgrade, a backdated discount or an early termination breaks a simple billing model, and you design for it before a customer finds it. - You know revenue. You understand order-to-cash in practice: contracts, billing schedules, deferred and recognised revenue, credit notes, dunning, and matching cash against invoices. You can talk confidently with a Controller about how revenue should land in the books. An accounting qualification (ACA, ACCA, CIMA, CPA or local equivalent) is a strong plus, and so is time spent running billing or revenue operations yourself. - You can say no, explain why, and keep the relationship intact. Lead to Cash attracts customer-specific requests, and many arrive already promised. You can tell a pattern from a one-off, explain the cost of each to Sales and to customers, and turn the patterns into product that serves the next customer as well as this one. - You’re AI-native. You’ve changed the way you work because of AI tooling, not just added it to your workflow. You use it to read contracts and pricing models, prototype, draft specs and pressure-test your own thinking, and you have an instinct for where it helps, where it misleads, and how to use it without losing ownership of the outcome. - You own discovery. You talk to customers directly and often: their finance teams, the people who run their billing, and our own Sales and Implementation teams who set them up. You can tell the difference between what a customer asks for and the problem underneath it, and you turn that into the smallest thing worth building next. - You deliver through other people. You’ve shipped through Product, Engineering, Design and Sales without formal authority over any of them. You build trust with senior finance stakeholders through clear communication and consistent delivery. - Fluent English; additional European languages a plus. *If the core of the role sounds compelling but you don’t tick every box, we’d still love for you to reach out and convince us you’re the right person. BONUS POINTS - Experience building billing, subscription or revenue recognition products, or running billing at a SaaS company - Familiarity with billing and payment platforms such as Stripe, Chargebee or Zuora, and CRMs such as HubSpot or Salesforce - Experience in fintech or systems where data integrity is non-negotiable - Experience with usage-based, tiered or hybrid pricing models - Background in high-growth startups where everything was still being figured out - Familiarity with multi-currency, multi-entity billing and e-invoicing mandates (e.g. Peppol, Italy’s SDI) YOU’LL PROBABLY STRUGGLE HERE IF - You need a finished spec handed to you. Here the “requirement” is often a contract clause or a pricing sheet nobody has turned into product yet. - You need a PMO, a mature methodology or a big delivery org around you to operate. This is a startup environment, and ownership and a self-starter nature are key. - You treat every customer request as a commitment. The job is deciding which ones become product. - You find it hard to say no to a customer or colleague, even when it’s the right call. - You haven’t yet changed how you work because of AI. We go all in on AI at Light and want people who share that. OUR TECH STACK We build on AWS, with a Kotlin backend, a React frontend, and infrastructure managed in Terraform. It’s a real production system that global finance teams depend on every day. You won’t be writing the code, but you’ll live alongside it. You do need to be comfortable in this kind of environment: real scale, real customers, real stakes.
