Senior Backend Engineer | Accounts Receivable

ABOUT RAMP Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $275B in annualized spend flows in and out of 85,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome. The median Ramp customer saves 7.5% and grows revenue 16% in their first year – far in excess of businesses operating without Ramp. We believe every ambitious company deserves the same. If you want to build systems that directly shape how companies move and manage billions, Ramp is the place to do it. ABOUT THE ROLE Getting paid is still one of the most manual parts of running a business. Finance teams chase invoices over email, match payments to invoices by hand in spreadsheets, and close the books late because cash data is scattered across banks, payment processors, and ERPs. Ramp's Accounts Receivable team is building the system that automates all of it, from the moment an invoice is sent to the moment cash is reconciled in the general ledger. We own the full receivables lifecycle: invoicing, collections, payments, cash application, and accounting sync. We're looking for a senior backend engineer to own core pieces of that system. The work sits where hard engineering problems meet real money: matching messy payment data to the right invoices, keeping ledgers correct to the cent, and syncing reliably with the accounting systems our customers depend on. You'll own projects end to end, from design through production, and work closely with product and design to turn complex finance workflows into software that just works. WHAT YOU’LL DO - Build the payment-matching systems that automatically apply incoming ACH, wire, card, and check payments to the right invoices, even when payment details are incomplete or inconsistent - Design accurate data models where every dollar is traceable from invoice to payment to general ledger - Build two-way integrations with ERPs like NetSuite and QuickBooks that stay consistent through retries, partial failures, and edits on either side - Build collections workflows that help businesses get paid faster without hurting their customer relationships - Own projects from problem definition and technical design through launch, monitoring, and iteration - Raise the engineering bar through design reviews, code reviews, and mentorship WHAT YOU’LL NEED - Product sense: you care about the customer problem, not just the ticket, and you push back when the spec is wrong - Experience designing and operating production backend systems, including APIs, data models, and asynchronous workflows - Strong system design judgment and the ability to balance speed, correctness, reliability, and simplicity - A track record of independently owning complex projects and shipping high-quality software - Strong communication skills and a collaborative approach to technical decisions NICE TO HAVES - Experience with invoicing, billing, payments, accounting, or other financial workflows - Experience building integrations that keep data consistent across systems - Experience improving reliability and operational visibility in a growing product BENEFITS AVAILABLE TO ALL FULL-TIME RAMP EMPLOYEES (GLOBAL) - Flexible PTO - Centralized home-office equipment ordering - Health and wellness stipend - Budget for intra-office travel - Weekly coffee stipend UNITED STATES - 100% medical, dental & vision insurance coverage for you, with partial coverage for dependents - One Medical annual membership - 401(k), including employer match on contributions made while employed by Ramp - Fertility HRA (up to $10,000 per year) - Parental leave: up to 16 weeks (birthing + bonding) or 8 weeks (bonding only) at 100% pay - Pet insurance - In-office perks: lunch, snacks, drinks, and more - Relocation expense coverage to NYC or SF (if needed) CANADA - Group medical, dental, and vision coverage through Sun Life - Life, AD&D, and disability coverage - Fertility drug coverage (up to $4,000 lifetime) - Group Retirement Plan with employer match (RRSP + DPSP) - Parental leave: up to 16 weeks (birthing + bonding) or 8 weeks (bonding only) at 100% pay, with additional time available at reduced pay - Employee Assistance Program and virtual care through Lumino Health UNITED KINGDOM - Private medical insurance through Freedom Elite - Virtual GP and at-home care via eMed x Livi - Workplace pension through Penfold, with salary sacrifice option - Parental leave: up to 16 weeks (birthing + bonding) or 8 weeks (bonding only) at 100% pay with additional time available at reduced pay REFERRAL INSTRUCTIONS If you are being referred for the role, please contact that person to apply on your behalf.
