Senior Software Engineer, Identity

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Software Engineer, Identity in Germany.

This role places you at the core of building secure, scalable identity systems that power modern digital platforms. You will design and maintain authentication and authorization infrastructure used by a large global developer base, ensuring every interaction remains secure and reliable. Working in a distributed, high-scale environment, you’ll tackle complex challenges across OAuth, SSO, and token-based systems. As AI-driven workflows evolve, you’ll help define how non-human actors securely interact with platforms. The position offers a strong mix of backend engineering, system design, and cross-functional collaboration. You’ll contribute to shaping next-generation identity models in a forward-thinking, remote-first environment that values autonomy and technical excellence.

Accountabilities:

• Design, build, and maintain authentication and authorization infrastructure supporting large-scale distributed systems
• Implement and evolve identity protocols such as OAuth 2.0, OIDC, SAML/SSO, session management, and JWT
• Ensure high reliability, performance, and security across identity services, from APIs to user-facing authentication flows
• Drive architectural improvements with a strong focus on scalability, resilience, and security best practices
• Develop identity solutions for AI and agent-based workflows, including attribution and trust mechanisms
• Collaborate cross-functionally with platform, security, and product teams to define identity standards and capabilities
• Contribute to code reviews, incident response, and ongoing improvements to engineering quality and processes

Requirements:

• Strong experience building backend systems using TypeScript/Node.js and PostgreSQL in production environments
• Deep expertise in authentication and identity standards (OAuth 2.0, OIDC, SAML, JWT, session management)
• Proven track record designing and operating distributed systems at scale, with a solid understanding of trade-offs and failure scenarios
• Security-focused mindset with knowledge of threat modeling, trust boundaries, and least-privilege principles
• Ability to work autonomously and take ownership of projects end-to-end in a remote setup
• Strong collaboration and communication skills across technical and non-technical teams
• Experience with Go, Lua, or cloud platforms is a plus

Benefits:

• Flexible and remote-friendly work environment across Europe
• Competitive salary package with location-based compensation
• Stock options program to share in company success
• Comprehensive healthcare coverage and wellness benefits
• Supportive, collaborative, and highly skilled international team
• Opportunities for continuous learning, growth, and career development
• Healthy work-life balance with flexibility for personal and family needs
