Job description
The Opportunity
Proton is building the industry cloud for distribution—an $8 trillion market that technology forgot.
Our first product is an AI-powered CRM built specifically for distributors—it helps their sales teams know which customers to call, what to sell them, and when. We’re at ~$10M ARR with 120%+ NDR. Our second product, PIM (Product Information Management), helps distributors manage their product catalogs—think millions of SKUs with specs, images, and pricing that need to stay accurate across systems. PIM is growing fast. Another product launches in March, with more on the roadmap.
We’re looking for a Senior Financial Analyst to be our finance lead. You’ll own the function—building our operating model, running FP&A, managing reporting and compliance, and working directly with the CEO on financial decisions. You’ll have one direct report (our bookkeeper) and full ownership of how finance runs at Proton.
If you succeed, you’ll have built the finance infrastructure that supports Proton’s growth from $10M to $50M+ ARR.
We are looking to hire someone in the greater Boston area who is open to a hybrid schedule (3 days in office, Havard square). The target salary range for this role is $140,000- $170,000. Final offers will be based on your skills and previous experience.
What You’ll Do
Own FP&A (40%)
- Build and maintain our operating model and budget
- Prepare monthly budget vs. actuals reporting
- Track and report on SaaS metrics (ARR, NDR, CAC, LTV, magic number, etc.)
- Prepare board materials and investor reporting
- Build bespoke financial analysis for business decisions
Run Financial Operations (40%)
- Oversee accounting: revenue recognition, month close, AP/AR
- Own billing, collections, and cash management
- Ensure compliance: corporate tax, sales tax, R&D tax credit, 409a valuations
- Calculate and manage variable compensation and partner commissions
- Lead Fiona (bookkeeper) and manage external accounting relationships
Partner with the CEO (20%)
- Be a thought partner on financial decisions
- Support fundraising preparation when needed
- Identify opportunities for financial process improvement
Who You Are
Non-Negotiables:
- SaaS metrics fluency. You understand ARR, NDR, CAC, LTV, burn multiple, and magic number cold.
- Financial modeling skills. You’ve built operating models from scratch and can maintain them as the business evolves.
- Startup experience. You’ve worked at a Series A or B stage company and understand the pace and ambiguity.
- Based in Boston. In office 3x/week in Kendall Square.
- Exceptional attention to detail. Your models are airtight. Your reports are accurate. You catch things others miss.
What Sets You Apart:
- You’re reliable. When you say something will be done, it gets done—on time and correctly.
- You’re curious. You dig into the numbers to understand what’s really happening in the business.
- You communicate clearly. You can explain financial concepts to non-finance people and help them make better decisions.
About Proton
Distribution is an $8 trillion industry that technology forgot. 75,000+ distributors globally. Half of their sales reps still don’t use a CRM. The ones that do are stuck with generic tools built for tech companies—not businesses managing millions of SKUs and thousands of customer relationships.
We’re building the industry cloud for distribution—and every product is AI-native from the ground up. We’re not bolting AI onto legacy software. We’re rebuilding the entire stack with AI at the core.
