pmtbox is building payments that actually work for the businesses that depend on them. After years of building and scaling payments companies — and with decades of fraud, risk, and merchant-ops experience on our founding team — we’re creating a platform centered on one simple idea: merchants deserve clarity, control, and outcomes that drive their growth.
We’re a merchant-first company. That means we prioritize transparency, unlock the data others obscure, and build tools that give merchants a real edge. We move fast, sweat the details, and build with intent — always focused on making payments the most powerful tool in commerce.
We’re growing quickly and looking for people who think like founders, act with ownership, and want to build something that lasts.
Why This Role Exists
We’re hiring a Senior Engineer to help build the core foundation of pmtbox. This is a full-stack role within a flat engineering team where you will work directly on payments, integrations, risk systems, infrastructure, and databases.
You’ll own a spoke end to end — from design to build to launch. This requires a birds-eye understanding of our unified payment architecture, paired with the willingness to get into the weeds and ship real product. We are not hiring a manager. We are hiring a builder.
What You’ll Work On
- End-to-end ownership of a spoke in our hub-and-spoke architecture.
- Full-stack development across backend, frontend, data, infrastructure, and integrations.
- Contributing to the evolution of our unified payments layer.
- Building merchant-facing tools, payment routing logic, fintech plumbing, and risk-adjacent systems.
- Working closely with founders and engineering to shape architecture and product direction.
- Shipping thoughtful, reliable code that moves the business forward.
What You’ll Bring
- Senior-level engineering experience (no specific year count required).
- Experience in fintech/payments or from the merchant side — ideally someone who has lived the pain points we’re solving.
- Comfort in early-stage environments and the fast pace that comes with them.
- Curiosity and willingness to learn our stack:
- Ruby on Rails (experience not required — curiosity and willingness to learn is)
- JavaScript
- Google Cloud
- Postgres
- Ability to think in systems and understand how your work fits into the larger architecture.
- A bias for action, ownership, and solving real problems without layers or bureaucracy.
Nice to Have
- Experience with payment routing, card acquiring, underwriting/risk tools, or financial operations systems.
- Experience with multi-tenant systems, real-time workflows, or complex integrations.
- Familiarity with cloud infrastructure, distributed systems, or observability.
How We Work
pmtbox functions primarily in-office in Orem, UT. We value focus, clarity, and collaboration — and our in-office rhythm supports that. That said, for exceptional engineers, we’re open to evaluating remote applications.
Compensation & Benefits
- Compensation is in line with senior-level experience
- $2,000 in Monthly QSEHRA reimbursement toward health insurance
- Safe Harbor 401(k) with 100% match up to 6%
- In-office snacks and drinks
- Bi-Weekly Friday team lunch with leadership
- High-trust, high-ownership environment

What We Do
At pmtbox, we believe payments should fuel growth, not hold it back. That’s why we focus on what matters most: lowering the cost of getting paid, simplifying the payments landscape, and unlocking new sources of revenue.
We help businesses keep more of what they earn by reducing fees and friction in every transaction. Our platform cuts through complexity by unifying payment processes and replacing outdated systems with seamless, transparent solutions. And beyond cost savings, we open new revenue opportunities by enabling businesses to access innovative payment rails, business models, and smarter ways to monetize.
With pmtbox, payments become clearer, faster, and more powerful — turning a cost center into a growth engine.
