Jobs at Djinni

Our Mission and Vision 

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That’s exactly the kind of teammates we want on board.
 

About the Role 

We’re building the smartest, fastest and most resilient payments infra in fintech — and risk is a core part of how we win. As a Risk Operations Analyst at Solidgate, you’ll be the one keeping our engine clean, sharp and one step ahead. You’ll monitor how merchants behave, how money moves, and how risk evolves in real time — making sure we scale safely without slowing down growth.This role is hands-on and impact heavy. You’ll use data, logic and frameworks to keep portfolio exposure healthy, protect revenue, and help us make better, smarter risk decisions every day. It’s fast. It’s complex. And if you love owning the signal inside the noise — you’ll thrive here.

What you’ll do

— Analyse risk signals, detect anomalies, and trigger the right actions or escalations
— Monitor compliance with international payment scheme requirements
— Control merchant reserves to prevent negative balances and minimise financial exposure
— Manage merchant cap limits in line with the portfolio’s risk appetite
— Execute and continuously improve daily operational tasks within approved risk processes
 

You’re a great fit if you have 

— Bright mind with a background in econometrics, finance, management, international relations, mathematics, or computer science— or still studying in one of these fields.
— A strong work ethic, great communication skills, and the ability to learn quickly — you get things done and pick up new skills on the go.
— A strong sense of responsibility and attention to detail — precision matters in risk.
— English B2+ — confident communication across teams and partners.

Nice to have 
— Self-starter — you can own your projects and take full responsibility for your area.
— SQL & Tableau — extra points if you know your way around data.

Why Solidgate? 

Fintech innovation at scale. We’re not just a PSP — we’re building a full-cycle European acquiring bank with direct access to schemes, regulators, and infrastructure.
Real impact. Your work shapes how we detect, assess, and mitigate risks across thousands of live transactions every day.
