Job description

fal is the generative media ecosystem powering the next generation of AI products. We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise. For developers and enterprises, fal is the foundation that makes generative media not just possible, but practical: a unified platform where high-performance inference, orchestration, and observability come together to unlock new categories of AI-native products.

About the Role

Cash flow is the fuel behind every hire we make and every GPU we spin up — and right now, that process runs on scrappy startup instincts more than scalable systems. We're hiring an AR Specialist to change that: someone who can take full ownership of collections, chase down what's owed without losing the relationship, and build the reporting and processes that let Finance actually see around corners. You'll sit at the intersection of Finance, Sales, Operations, and Customer Success, which means your work is never just about invoices — it's about making sure the whole revenue engine runs cleanly as we scale. If you get real satisfaction from replacing chaos with a system that just works, this role was built for you.

What You'll Do

Own Accounts Receivable, start to finish

• Run the full Account Receivable lifecycle — invoicing, payment tracking, account reconciliation

• Watch aging reports like a hawk and chase down outstanding invoices before they become a problem

• Keep customer account records clean and resolve billing discrepancies fast

• Support month-end close for everything AR and cash application related

Drive collections and cash flow

• Design and execute collection strategies that shrink DSO and speed up cash collections

• Build real relationships with customer AP teams — the kind that get payment delays resolved with a phone call, not an escalation

• Know when to elevate high-risk or delinquent accounts, and do it without burning the relationship

• Spot payment risk early by reading the trends before they become write-offs

Build the systems, not just run them

• Use collections tools to automate outreach and track performance — this isn't a spreadsheets-forever role

• Partner with Finance leadership to level up AR processes, reporting, and controls

• Work with Sales to make sure billing is accurate from the first invoice

Report on what matters

• Put together weekly AR aging and collections reports for leadership

• Track DSO, collection effectiveness, and overdue balances like they're your own scorecard

• Support audits and keep documentation clean for compliance

What You'll Bring

Must-haves

• 3+ years in Accounts Receivable, Billing, or Collections

• Comfortable in a SaaS, tech, or startup environment

• Solid grasp of AR processes, collections strategy, and cash application

• Experience with an ERP/accounting system

• Strong communicator and negotiator — genuinely fine picking up the phone and calling a customer

• Organized, detail-obsessed, and good at juggling deadlines when things move fast

Nice-to-haves

• Hands-on experience with Tesorio or similar AR automation/collections platforms

• Experience supporting enterprise or B2B customers

• Familiarity with SaaS billing models, contracts, and revenue operations

• Comfortable using AI tools to speed up analysis and reporting
