What you'll do

• Write clean, highly secure, performance-optimized code for critical authentication paths and build Proof of Concepts (PoCs) to evaluate new architectures.
• Architect resilient, low-latency microservices capable of handling millions of token validations, federation requests and authentication flows globally.
• Drive engineering modernizations, including upgrading backend frameworks, implementing secure CI/CD pipelines and integrating advanced security analysis tools.
• Lead root-cause analysis and resolution of critical bugs involving multi-tenant SSO setups, token encryption/signing and token lifecycles.
• Partner with data science teams to integrate AI/ML models into authentication flows for real-time risk scoring and anomalous token behavior detection.
• Advocate for and embed generative AI development tools into the team's daily workflows to safely accelerate delivery and improve code quality.
• Lead large-scale features, protocol refactors and microservice optimizations, ensuring alignment with the company's Tech Radar and security baselines.
• Identify architectural gaps in SSO services, advocate for improvements and implement robust solutions.
• Conduct rigorous reviews of complex protocol implementations and cryptographic designs to ensure strict adherence to RFC standards.
• Proactively identify and resolve cross-team technical dependencies for seamless integration.
• Teach, guide and upskill developers, fostering a culture of deep identity security awareness.
• Represent the company in the cybersecurity industry by speaking at tech conferences, writing technical blogs or contributing to open-source identity standards.

What you'll need

• Experience in at least one of: C#/.NET, Java or Python; willingness to work with the C#/.NET technology stack.
• Exposure or strong interest in applying AI/ML technologies within cybersecurity contexts.
• Strong background in modern cloud-native architectures, distributed microservices and secure-by-design engineering principles.

Nice to have

• Proven experience in public speaking, technical writing (blogs/whitepapers) or mentoring engineering communities.
• Broad understanding of the business context, connecting technical decisions to customer value.
• Ability to translate highly complex technical concepts for both engineering and business stakeholders.
• Deep, hands-on expertise with Identity and Access Management (IAM) architectures, specifically building and securing SAML 2.0 Identity/Service Providers and OAuth 2.0/OIDC Authorization Servers.
