Senior Backend Engineer | Accounts Receivable

About RampRamp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $200B in annualized spend flows in and out of 70,000+ 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 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 RoleGetting 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 DoBuild 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 inconsistentDesign accurate data models where every dollar is traceable from invoice to payment to general ledgerBuild two-way integrations with ERPs like NetSuite and QuickBooks that stay consistent through retries, partial failures, and edits on either sideBuild collections workflows that help businesses get paid faster without hurting their customer relationshipsOwn projects from problem definition and technical design through launch, monitoring, and iterationRaise the engineering bar through design reviews, code reviews, and mentorshipWhat You’ll NeedProduct sense: you care about the customer problem, not just the ticket, and you push back when the spec is wrongExperience designing and operating production backend systems, including APIs, data models, and asynchronous workflowsStrong system design judgment and the ability to balance speed, correctness, reliability, and simplicityA track record of independently owning complex projects and shipping high-quality softwareStrong communication skills and a collaborative approach to technical decisionsNice to HavesExperience with invoicing, billing, payments, accounting, or other financial workflowsExperience building integrations that keep data consistent across systemsExperience improving reliability and operational visibility in a growing productBenefits available to all full-time Ramp employees (Global)Flexible PTOCentralized home-office equipment orderingHealth and wellness stipendBudget for intra-office travelWeekly coffee stipendUnited States100% medical, dental & vision insurance coverage for you, with partial coverage for dependentsOne Medical annual membership401(k), including employer match on contributions made while employed by RampFertility HRA (up to $10,000 per year)Parental leave: up to 16 weeks (birthing + bonding) or 8 weeks (bonding only) at 100% payPet insuranceIn-office perks: lunch, snacks, drinks, and moreRelocation expense coverage to NYC or SF (if needed)CanadaGroup medical, dental, and vision coverage through Sun LifeLife, AD&D, and disability coverageFertility 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 payEmployee Assistance Program and virtual care through Lumino HealthUnited KingdomPrivate medical insurance through Freedom EliteVirtual GP and at-home care via eMed x LiviWorkplace pension through Penfold, with salary sacrifice optionParental leave: up to 16 weeks (birthing + bonding) or 8 weeks (bonding only) at 100% pay with additional time available at reduced payReferral InstructionsIf you are being referred for the role, please contact that person to apply on your behalf.Other noticesPursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.Beware of recruiting scams: Ramp will only contact you through official @Ramp.com email addresses and will never ask for payment or sensitive personal information during the hiring process.Ramp Applicant Privacy NoticeCompensation Range: $204K - $280KLocationNew York, NY (HQ); Remote (Canada); Remote (US)Employment TypeFull timeLocation TypeHybridDepartmentEngineeringCompensationTarget Base Salary $204K – $280K • Offers EquityThe final compensation will depend on the location and level at which the candidate is hired.
