• Integrate modern protocols like MCP (Model Context Protocol) to enable richer AI context sharing and dynamic system behavior.
• Mentor and coach engineers driving excellence in code quality, architecture, and delivery.
• Lead end‑to‑end delivery from design through deployment ensuring scalability, resilience, and observability.
• Champion secure and policy‑driven architecture leveraging SSO federation, OAuth2/OpenID Connect, and Open Policy Agent (OPA).

Your skills and experience that will help you excel

• 10‑15 years of backend or platform engineering experience.
• Proven experience building and deploying microservices in production within a cloud environment (AWS, Azure or GCP).
• Expertise in Go or Java with deep understanding of distributed systems and API design.
• Experience integrating or leveraging AI/ML models or services within production systems.
• Familiarity with AI‑assisted development tools and a strong belief in data‑driven intelligent engineering.
• Experience with Kubernetes, Docker and CI/CD pipelines.
• Exceptional communication and collaboration skills with a track record of technical mentorship.

Preferred Qualifications

• Familiarity with the Model Context Protocol (MCP) or similar frameworks for AI‑context sharing.
• Understanding of authentication and federation standards (OAuth2, OpenID Connect, SAML).
• Experience with Open Policy Agent (OPA) or other policy‑as‑code models.
• Exposure to vendor API ecosystems and secure platform integrations.
• Passion for using AI to augment engineering processes and platform intelligence.

What we offer you

• Transparent compensation schemes and comprehensive employee benefits tailored to your location.
• Flexible working arrangements, advanced technology and collaborative workspaces.
