Senior Go Developer
Summary
As the first technical hire, this person will design and build MOR.AI’s Go-based V1 payment platform from scratch, owning backend services, APIs, infrastructure, billing, and MoR/PayFac integrations with acquirers and card networks. They will make core architecture decisions, use AI coding tools, and grow into a CTO while building the engineering team.
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 second 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.
