- Contribute to technical and architectural decisions around component design, database changes and API contracts.
- Build and deploy cloud-native applications across Azure or AWS.
- Work with SQL Server and NoSQL technologies such as CosmosDB and DynamoDB.
- Build and maintain microservices and REST APIs.

- Participate in code reviews, pair programming and technical discussions.
- Help troubleshoot production issues and continuously improve the performance and reliability of our products.
- Share knowledge and provide peer mentoring to junior engineers.
- Use AI-assisted engineering tools responsibly to improve development, testing and debugging.
