Last updated on November 7, 2026

Join Rublon and work with a team of cybersecurity enthusiasts building the future of enterprise user authentication.

Rublon MFA is a multi-factor authentication platform used by customers in more than 60 countries to protect employee logins to networks, servers, and applications. We build cloud-based authentication services, APIs, and cybersecurity integrations for enterprise environments.

We are looking for someone who knows Laravel well, works independently, and wants to grow in identity security. Experience with another enterprise SaaS product is a strong advantage.

We work with AI-assisted development and Agentic Engineering. Tools such as Claude Code are standard in our daily work: we use them for planning, implementation, testing, code review, and documentation, while staying fully responsible for the quality, security, and correctness of the code.

How You’ll Work

• Employment contract: full-time at our office in Kraków or Zielona Góra (no remote work)
• B2B contract: 100% remote from anywhere in Poland
• Technology stack: PHP 8.3, Laravel 12, Angular, TypeScript, Docker, GitHub, CI/CD, AWS, SAML, OpenID Connect, OAuth 2.0, LDAP, Microsoft Entra ID, AI coding agents (e.g. Claude Code)
• Team: Core, responsible for the heart of the Rublon MFA platform
• Language: Polish in the team’s daily work
• Self-development: access to online training courses and sponsored certifications

• Develop integrations with Microsoft 365 (Microsoft Entra ID, Microsoft Sentinel, Microsoft Defender) and other IAM and SIEM systems
• Build frontend features in Angular and TypeScript where needed
• Take care of security: authentication, authorization, session and token handling, data protection, and resilience to common attacks
• Implement features within the agreed architecture and propose improvements
• Write unit, integration, and end-to-end tests and keep code quality high
• Work with CI/CD pipelines in GitHub, Docker containers, and AWS services

• Zero Trust and OpenID CAEP
• Infrastructure as code (e.g. Terraform)
• Building agentic workflows that support development, testing, and code review
• AWS or security certifications
• Formal education in Computer Science, Cybersecurity, or a related field, or equivalent practical experience
