• 7+ years of experience in software product development with customer-facing systems at scale.
• Strong experience with Java, REST APIs, and relational/NoSQL databases.
• Practical experience designing and implementing microservices.
• Familiarity with modern front-end frameworks.
• Hands-on experience with Docker and cloud-based deployments.

Preferred

• Exposure to Kubernetes and cloud-native environments.
• Experience using AI coding tools (e.g., Claude Code, GitHub Copilot).

Why Join OneSpan

• Lead the product strategy for a market-leading passkey solution trusted by some of the world's largest banks.
• Work at the frontier of FIDO2/passkey technology with a team that has been in the space from the beginning.
• Collaborate with a global team of security experts and make a tangible impact protecting hundreds of millions of users.
• The opportunity to shape a category-defining product at the forefront of the passwordless movement, with real impact on how hundreds of millions of people authenticate.
• Be part of a company recognized as a KuppingerCole 2026 Leadership Compass leader in Passwordless Authentication for Enterprises.
