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 escalate 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

• Help build the scalable AR playbook a high-growth startup actually needs

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

Must-haves

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