Job description

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 modernise 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.

About The Role

You’ll own several concurrent implementations end to end—from contract signature to go‑live. The plan, the customer relationship, the scope, the timeline, the outcome. You hand over to Customer Success once the customer is live.

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 on multi‑entity accounting, consolidation, intercompany, multi‑currency and statutory reporting—and to tell them straight when they’re asking for something that won’t work.

No two implementations look the same. Every customer brings problems that don’t have a textbook answer—a consolidation edge case, a migration shape the playbook doesn’t cover, a process that needs rebuilding before it can be automated. You’ll work the problem, ship the answer, and move on.

Key Responsibilities

• Own several concurrent implementations end to end, from kickoff to go‑live
• Run the customer relationship through implementation—Controllers, Finance Directors, CFOs
• Translate finance requirements into platform design—chart of accounts, entity structure, consolidation logic, reporting
• Lead data migration—chart of accounts mapping, opening balances, historical data, cutover
• Hold scope through the project—keep delivery aligned to what was sold, surface and reset drift early
• Push back on requests that won’t work, and bring the customer with you
• Spot projects going off‑track before the customer does, and intervene
• Train and enable customer finance teams to run on Light from day one of go‑live
• Contribute to the playbooks, templates, and patterns the team builds over time

Experience & Qualifications

• Degree in finance, accounting, business, or a related field
• 5+ years in finance transformation, ERP implementation, or finance advisory—Big 4, a finance‑focused boutique, or a vendor‑side professional services team (NetSuite, Sage Intacct, Workday Financials)
• Fluent in accounting and can hold your own with a Controller on multi‑entity consolidation, intercompany eliminations, accrual accounting, statutory vs management reporting. Qualified accountant is a plus, not a requirement
• Bring structure to messy projects—clear plans, sharp prioritisation, and judgment to know which details matter and which don’t
• Excel at building trust with C‑suite executives and finance leadership teams through clear communication and consistent delivery
• Comfortable working cross‑functionally—delivered through Product, Engineering, Sales, and customer teams without formal authority over any of them
• Diagnose implementation issues quickly and deliver practical solutions that balance customer needs with technical feasibility
• Have a real implementation with your name on the go‑live—vendor‑side, consulting‑side, or as the lead on a customer‑side migration. Not “I’ve used an ERP”
• Use AI tools daily, have specific opinions on where they help in delivery work and where they don’t
• Fluent English; additional European languages a plus
• Bonus: multi‑jurisdiction experience (IFRS, US GAAP, local GAAPs); experience losing a customer or missing a go‑live and learning from it

You’ll probably struggle here if

• You’ve only ever implemented one ERP, or on one customer— you’ll be running multiple implementation projects simultaneously
• You need a PMO, a mature methodology, or a big delivery org around you to operate—you’ll be in a startup environment, without a large structure/org surrounding you, ownership and a self‑starter nature is key
• You’ve never owned a go‑live solo; someone else was always accountable— see above!
• You can’t give a concrete example of telling a senior customer “no” and making it stick
• You’ve used ChatGPT once and weren’t impressed— we go all in on AI at Light and need people just as passionate about it!

Benefits

• Competitive salary and potential stock options
• Generous package of paid annual leave and public holidays in the country where you are based
• Regular socials and company off‑sites
• Huge opportunity for career growth as you'll help shape a market‑defining product
