Description du poste

Let’s shape the future of finance - together

At Isabel, we believe that real innovation happens when people and ideas connect

That’s why we’re building more than technology, we’re building an ecosystem.

One where every voice counts, and where your work can truly make a difference.

We’re looking for curious minds and collaborative builders. People who believe success means growing together, learning from each other, and challenging the status quo.

If that sounds like you, keep reading.

Fraud is evolving fast, and fraudsters are exploiting the fragmentation of the financial ecosystem to deceive victims and outpace bank anti-fraud teams.

Detecting fraud schemes and protecting victims requires collaboration across financial institutions, trusted partners such as telecom operators and technology platforms, and public authorities.

You will work on TILDA, a neutral platform that provides a secure, governed environment where banks and other trusted partners can exchange fraud signals and collaborate on investigations. Our mission is to connect the right signals with the organizations best placed to act on them.

What you’ll do

• Break delivery objectives into clear tasks, constraints, and acceptance criteria for AI agents

• Hands-on building, testing and deploying solutions

• Remain accountable for the quality, security, correctness, and maintainability of delivered software

• Contribute to architecture and technical design discussions

• Translate evolving functional needs into pragmatic technical solutions

• Work autonomously and move delivery forward when specifications are incomplete

• Improve reusable AI development workflows, engineering standards, and guardrails

• Collaborate with Product, Architecture, Security, Ops, and SRE colleagues

• Orchestrate AI agents to accelerate analysis, design, implementation, testing, and documentation

What makes you a great fit

The role requires comfort with ambiguity and the ability to adapt quickly to changing needs, requirements, and technologies. Continuous learning, adaptability, and ongoing improvement are core to how the team operates and how success in this role is defined.
