Senior Go Developer

MOR.AI is building the next generation of payment infrastructure — a Merchant of Record platform and a network of PayFacs.

We’re looking for our first technical hire — someone who can take the product from 0 → 1, build the platform from scratch, and eventually grow into a CTO role.

This is not a corporate job. You’ll own the architecture, infrastructure and delivery from day one.

What you’ll do

Architect and build the entire V1 platform from scratch in Go

Own backend, APIs, infrastructure and complex billing systems

Design and build MoR / PayFac architecture

Work hands-on with payment infrastructure, acquirer integrations and card network rules

Make key technical decisions and move fast

Build and lead the engineering team as the company scales

Take ownership of the technical function as the company grows

What we’re looking for

Payments experience is mandatory. We’re looking for someone with hands-on experience in payment infrastructure and payment systems, including PayFacs, acquirers and card networks.

You should:

Have strong backend engineering experience with Go / Golang

Be able to independently architect and build a V1 product

Be comfortable being the only developer for an extended period

Have hands-on experience with payments

Understand payment infrastructure, billing systems and MoR / PayFac architecture

Think like a founder, not a corporate employee

Be highly hands-on, fast and execution-oriented

Be AI-native and use tools such as Cursor, Copilot, Claude, etc. to significantly accelerate development

Have the ambition to build and lead an engineering team

The opportunity

Base salary: market or below-market

Significant % of EBITDA — real profit sharing, not just illiquid equity

Clear, performance-based path to CTO

Become the first technical hire and have real ownership from day one

If you’re looking for a comfortable corporate role, this is probably not for you.

If you want to build something from the ground up, shape the architecture, build the team and participate directly in the profits — let’s talk.
