· Technical Leadership: Lead design sessions, make foundational architecture decisions, and write clean, maintainable, and well-documented code.

· Security & Performance: Optimize applications for scalability, reliability, and security. Ensure systems adhere to strict corporate compliance and security policies.

· Troubleshoot: Debug complex production issues (including identity, session management, and database bottlenecks) and implement permanent, sustainable solutions.

· Collaboration & Mentorship: Partner with Product Owners, UX Designers, and Cloud Engineers. Actively mentor junior developers and promote engineering best practices.

Required Qualifications

Education: Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent professional experience).

Experience: 8+ years of professional full stack and backend software development experience.

Backend Mastery: Strong, hands-on experience in at least one core backend language (e.g., C#/.NET, Java, or Node.js/TypeScript).

Frontend Knowledge: Experience with modern frontend frameworks (ideally React or Angular), HTML5, CSS3, and JavaScript.

API & Database Design: Extensive experience designing, securing, and consuming RESTful APIs, alongside solid knowledge of relational databases (e.g., SQL Server, PostgreSQL).

Enterprise Security: Solid understanding of secure coding practices, OAuth2/OIDC, JWT, SAML, and directory integrations (e.g., Active Directory).

Accessibility: Strong understanding of and experience with accessibility standards (WCAG).

Cloud & DevOps: Experience deploying and maintaining applications on cloud platforms (Azure or GCP) using Git and CI/CD pipelines.

Preferred Qualifications

· Experience with containerization (Docker, Kubernetes) and microservice orchestration.

· Experience with event-driven architecture and messaging systems (e.g., Kafka, RabbitMQ).

· Familiarity with Agile/Scrum methodologies in a large-scale enterprise environment.

· Experience developing reusable design systems or custom UI component libraries.
