Europeerpaccountingfinancial reportingimplementation management
Own and manage multiple software implementations end to end for financial controller and CFO clients in SaaS and tech companies.
Responsibilities
- 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 to the next one.
- 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
Requirements
- 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)
- You are 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
- You bring structure to messy projects — clear plans, sharp prioritisation, and the judgement to know which details matter and which don't.
- You excel at building trust with C-suite executives and finance leadership teams through clear communication and consistent delivery.
- You are comfortable working cross-functionally — you have delivered through Product, Engineering, Sales, and customer teams without formal authority over any of them
- You diagnose implementation issues quickly and deliver practical solutions that balance customer needs with technical feasibility.
- You 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"
- You 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
Other
- 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.
- You've only ever implemented one ERP, or only ever 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 operating 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!
- 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 in the country where you are based.
- 🥳 Regular socials and company off-sites (last time was Northern Italy and next time is in October).
- 🚀 A huge opportunity for career growth as you'll help shape a market-defining product.
- 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.
