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.

The Role

Partners are central to how Light grows. Accounting firms, advisory practices and implementation partners bring us into deals, deliver alongside us and help finance teams move off legacy ERPs.

As Senior Partner Sales Manager, you’ll own partner-sourced and partner-influenced revenue across a portfolio of strategic partners in five regions. You’ll recruit the right partners, build plans with them and turn those relationships into qualified pipeline and closed deals, working hand in hand with our account executives. You’ll work closely with Sales, RevOps, Solutions Engineering, Marketing and Legal.

This is a senior seat in building Light’s partner programme. You’ll own a revenue target, and you’ll help shape how partnerships work here for years to come.

What You’ll Do

Own a revenue target for partner-sourced and partner-influenced pipeline and bookings across your portfolio

Recruit and sign new strategic partners: accounting firms, Big 4 and mid-tier advisory practices, ERP implementers and VC/PE networks

Build a joint business plan with each partner, covering target accounts, how you’ll sell together and quarterly pipeline goals

Co-sell with partners and our AEs through account mapping, joint prospecting, introductions and deal strategy

Negotiate partner commercials with Legal, including referral and rev-share terms, MOUs and reseller agreements

Get partner teams confident on Light’s positioning, pricing and demo, including running bootcamps and certification

Keep deal registration, attribution and partner data clean in HubSpot, and report pipeline weekly to leadership

Build executive relationships inside partner firms and represent Light at partner events and industry forums

Bring what you learn from partners and the market back to Product, Marketing and Sales

What Success Looks Like

First 30 days: You know Light’s product, pricing and ideal customer, and you’ve met every partner in your portfolio and the AE team in each region.

First 90 days: Each priority partner has an agreed joint business plan, the first partner-sourced opportunities are in pipeline, and you’ve signed a new partner.

First 12 months: You’ve hit your partner-sourced bookings target, priority partners are delivering a steady flow of qualified opportunities, and partner teams are certified.

What We Think* You’ll Need

Around 7 years in B2B SaaS sales or partnerships, with real time carrying a partner or channel number

A track record of hitting partner-sourced revenue targets on mid-market and enterprise deals

Existing relationships with accounting, advisory or ERP implementation firms in at least one of our regions

Working knowledge of finance software (ERP, accounting, close, spend or FP&A) and how CFOs buy it

Confidence negotiating partner agreements and commercial terms

Strong CRM discipline in HubSpot or Salesforce, and comfort reporting on pipeline and attribution

Excellent written and spoken English, and the ability to present with confidence to partner leadership and CFOs

A collaborative spirit. You build trust with partners and colleagues alike, and you win as a team.

*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 at a finance software company such as NetSuite, Sage Intacct, Workday or a modern finance platform

Experience launching a partner programme or entering a new market
