You’ll collaborate closely with engineering peers, architects, and product owners to bring business ideas to life while contributing to the overall architecture and development best practices of the team. You’ll also support the deployment and operationalization of code using CI/CD pipelines and infrastructure-as-code practices.

• Experience: Significant professional experience in backend development as a Senior role.
• Languages/Frameworks: Strong proficiency in Python with hands-on experience in asynchronous programming, concurrency and multithreading.
• API Expertise: Proven experience in building and integrating APIs, with expertise in API documentation and schema definition using OpenAPI/Swagger. Strong understanding of RESTful API design, authentication/authorization standards, and API lifecycle best practices; familiarity with Microsoft Graph API is a plus.
• API Lifecycle: Experience across the full API development lifecycle - including versioning, documentation, automated testing, deployment, and monitoring - using modern API management practices and tools.
• Integration Development: Proven experience building both client-side and server-side API-level integrations in Python.
• Security: Experience implementing and managing OAuth and OpenID Connect (OIDC) flows, with a solid understanding of API security, identity management, and selecting the right approach for different scenarios.
• Databases: Solid experience working with both SQL and No-SQL databases.
• Cloud Services: Practical knowledge of popular Azure services such as Function Apps, API Management, Application Gateway, Service Bus etc.
• DevOps Tools: Working knowledge of GitHub and CI/CD practices using tools like GitHub actions and Azure DevOps pipelines.
• Soft Skills: Self-motivated, result-oriented, and an excellent team player with strong problem-solving and communication skills.
