Retire the ERP.
Light exists to replace factory-era ERPs with software that feels alive. Light's Smart Financial Platform gives modern, global companies superpowers: automated accounting, real-time reporting, and financial flows that move at the speed of the business.
Light builds with its customers, ships fast, and obsesses over craft. In a short time, Light has gone from idea to the operating core for leading companies like Lovable, Legora, and Keyshot. People do not just use Light; they enjoy it.
Light is an early team defining a new software category. Think of engineers who love debits and credits, designers who care about reconciliation states, and operators who treat finance as a product. If you are excited to modernise how the world runs money—one workflow at a time—you are in the right place.
Backed by world-class investors and advised by industry titans, Light is building category-defining products with the freedom to ship ambitiously and own outcomes. Come help Light make Light the global default for next-gen finance.
About the Role
You will own several concurrent implementations end to end—from contract signature to go-live. This includes the plan, the customer relationship, the scope, the timeline, and 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. These are senior, technical, and time-poor individuals. They expect you to keep up on multi-entity accounting, consolidation, intercompany, multi-currency, and statutory reporting—and to tell them straight when they are asking for something that will not work.
No two implementations look the same. Every customer brings problems that do not have a textbook answer—such as a consolidation edge case, a migration shape the playbook does not cover, or a process that needs rebuilding before it can be automated. You will work the problem, ship the answer, and move on to the next one.
Key Responsibilities
Own several concurrent implementations end to end, from kickoff to go-live.
Run the customer relationship through implementation—with Controllers, Finance Directors, and CFOs.
Translate finance requirements into platform design—including chart of accounts, entity structure, consolidation logic, and reporting.
Lead data migration—covering chart of accounts mapping, opening balances, historical data, and cutover.
Hold scope throughout the project—ensuring delivery aligns with what was sold, and surfacing and resetting drift early.
Push back on requests that will not 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—such as 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, and statutory versus management reporting. Being a qualified accountant is a plus, but not a requirement.
You bring structure to messy projects—with clear plans, sharp prioritisation, and the judgement to know which details matter and which do not.
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—having 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—whether vendor-side, consulting-side, or as the lead on a customer-side migration. This is not merely 'I have used an ERP'.
You use AI tools daily, and have specific opinions on where they help in delivery work and where they do not.
Fluent English; additional European languages are 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 have only ever implemented one ERP, or only ever on one customer; you will be running multiple implementation projects simultaneously.
You need a PMO, a mature methodology, or a big delivery organisation around you to operate; you will be operating in a startup environment without a large structure or organisation surrounding you. Ownership and a self-starter nature are key.
You have never owned a go-live solo; someone else was always accountable—see above!
You cannot give a concrete example of telling a senior customer 'no' and making it stick.
You have used ChatGPT once and were not impressed; Light goes all in on AI and needs people just as passionate about it!
The good stuff
In addition to being part of a great team and working in a really fun and innovative environment, Light offers:
A competitive salary plus potential stock options.
Generous package of paid annual leave plus 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 will help shape a market-defining product.
The famous last words
Working at Light means you are embarking on an exciting journey to reshape the future of multinational financial operations. Light's cheat code is that Light has built something like this before—and is now doing it again, only better. Light's goal is to make global finance effortless and empower companies to make informed decisions.
