The Opportunity

Ralio is the payments layer for AI Agents. If you can imagine the challenges that this brings, please keep reading.

We’re backed by very strong early investors and are now hiring Founding Engineers to help shape the product, architecture, and engineering culture from the ground up.

This is a high-impact, high-agency role. You are the architect of our future codebase and the seed of our future engineering team.

What you’ll build

You will build the platform that AI Agents need to be able to pay safely. This involves building AI Agents, guardrails and integrations with payment providers, among other things.

What You’ll Do

Own end-to-end delivery of product features, from architecture and APIs to frontend, UX, infrastructure and deployment
Shape the technical vision and make foundational decisions about our technology stack and infrastructure
Wear many hats: engineer, product thinker, problem-solver
You’ll be challenged, you’ll grow, you’ll build something exciting

Who You Are

A Builder: You’re excited by building from scratch. You care about craft, but you also understand the importance of speed.
Product-Minded: You care about why we are building a feature, not just how. You are willing to push back on founders if a feature doesn't make sense for the user.
Comfortable with Ambiguity: You don't need a detailed spec sheet. You can take a high-level goal and figure out the implementation details.
Language Agnostic: You may have a preferred stack, but you are willing to pick up whatever tool does the job best.

You want to join a company early enough that your fingerprints are everywhere, but with the backing and clarity to go fast.

What You’ll Bring

Experience building products with AI
Familiarity with agentic frameworks like Autogen, LangGraph, Google’s ADK, OpenAI Agents SDK
Programming languages are a tool, ideally you are proficient in more than one, but we use Python and Typescript
You have full stack experience, we use React and Supabase
Experience with payments systems is a plus

What We Offer

Ownership: Significant equity package. You are not just an employee; you are a partner in our success
Impact: Your work will be on the edge of what’s possible. No red tape, no bureaucracy
Flexibility: We are in a rapidly changing environment, so we prioritise face to face communication as it’s still the most effective style. We are at the same time outcome driven and flexible on working hours and location
The Team: We are experienced fintech founders with payments and AI background, and we are backed by a great group of investors and advisors. We work hard, because we know that there’s no other way of achieving great things. We also prioritise our mental and physical health because we are long term thinkers

How to Apply

Share your CV, GitHub, or anything that represents your work.
