The Full Stack Engineer will build and maintain features for payments and invoicing systems, integrating Stripe and Fiserv APIs, while ensuring system reliability and data integrity.
We’re looking for a Full Stack Engineer focused on Payments to own and scale the systems that move money across Haulvana — both on the backend (billing, payments, settlements) and the frontend (dashboards, transaction logs, customer-facing views).
You’ll integrate with Stripe for platform-level payments and payouts, and Fiserv for enabling haulers to directly invoice and charge their own customers. Your work will ensure every dollar is tracked, every flow is auditable, and every user — whether dispatcher or business owner — has full confidence in the system.
This role is ideal for someone who has worked in fintech, B2B SaaS, or platform billing infrastructure, and wants to solve real-world payment challenges with speed, accuracy, and empathy.
- Build and maintain full-stack features supporting invoicing, payments, and account balances
- Integrate and extend Stripe APIs (Connect, Billing, Webhooks) for Haulvana’s internal payments
- Work with Fiserv APIs to enable haulers to bill and collect from their end customers
- Build secure, audit-friendly backend systems for ledgers, settlements, and error handling
- Develop dashboards and notifications for transactions, payment status, and invoice tracking
- Collaborate with Product and CS to resolve billing issues and iterate on payment features
- Ensure uptime, reliability, and data integrity across all financial flows
- 4+ years experience as a problem solver
- Attention to detail
- Excellent communication skills
- Deep understanding of technology
- Proven record of shipping features on time and on budget
- Flexible and focussed on solutions
- Organized and self-sufficient
- Health insurance with 100% premium covered
- Generous PTO / sick leave
- 401(k) plan with employer match
- Free lunch and snacks
- Annual company retreat
- Bring your dog to work 🐶
