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 to the next one.

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)

• 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 and 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

You'll probably struggle here if

• 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!

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 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.

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.
