About this role

ABOUT BJAK

The original mission of BJAK is we believe people deserve smarter ways to plan, save and grow their money. This is the origin of our name.

Started in 2019, we built the first mobile-first, insurance platform, enabling insurance to be accessible online by millions in the region. Today, its the leading insurance platform in Southeast Asia.

Today, we are expanding ways to help people in the region — this includes spending, saving, investing, exchanging, travelling, and more. Our mission is help people get more from their money every day.

We have teams working around the world, with over 20 nationalities from our offices and remotely, who truly enjoys their work. We are looking for the most talented and driven people we can find. We are looking for people who work for their passion, not counting hours. Who loves building great next-generation products, not status quo. Who cares about redefining how everyone around us can get the best financial applications, not for an exclusive few.

If you're this person, we'd love to talk to you.

THE ROLE

Secure BJAK's AI-enabled products and agent workflows using third-party models. Focus on customer data shared with model providers, agent permissions, user data isolation, and prompt injection through uploaded documents and other untrusted content.

WHAT YOU WILL BUILD

• Assess customer data sent to third-party model vendors, including minimization, vendor controls, retention, logging, and approved use.

• Design controls limiting AI agent permissions, tools, actions, and system access using least privilege and explicit authorization.

• Implement and test tenant and user data isolation across prompts, conversation history, retrieval, memory, and AI-connected services.

• Threat model and test prompt injection and indirect injection through uploaded documents, retrieved content, links, and other untrusted inputs.
