The Opportunity

Ralio is the payments layer for AI Agents. 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.

Growth: You are not only guaranteed, but expected to grow.

Benefits: Other great perks like health.

How to prepare for a job interview at Ralio

✨Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

✨Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Ralio uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

✨Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
