Founding Software Engineer - Agentic Systems

At Veriff, we are exploring the next frontier of identity verification: agentic AI systems that can reason, act, and operate safely in high-trust environments. We are forming a small, high-leverage team to explore and productionize agentic capabilities across identity, KYA, risk assessment, and automation workflows. We are looking for a Founding Engineer to help build this from the ground up.

You'll help us protect honest people online by

• Design and build agentic systems that can use tools, reason across multi-step workflows, and operate under strict compliance and safety constraints
• Prototype and productionize LLM-powered workflows
• Build internal evaluation frameworks for agent reliability
• Define system architecture for scalable, secure AI services
• Work closely with product, risk, and compliance teams
• Turn ambiguous ideas into working systems

You are the right future Veriffian for the job if you have
