Strong software design skills, with experience in domain-driven design (DDD), object-oriented principles, and the application of design patterns to real-world systems
Proficiency in one or more modern programming languages such as C#, Golang, or Java, with the flexibility and curiosity to learn new technologies as needed
Hands-on experience with cloud platforms such as AWS, Google Cloud, or Azure, and a solid understanding of building and operating cloud-native applications
Experience with event-driven and distributed architectures
Good understanding of integration approaches and technologies, including RESTful APIs, message-based communication, and asynchronous workflows
Strong analytical and problem-solving skills, with the ability to investigate complex issues independently or collaboratively with peers
Passionate about engineering excellence, automation, and continuous improvement, with an enthusiasm for learning and sharing knowledge
Clear and confident communication skills, both written and verbal, and the ability to work effectively in cross-functional teams

Nice to have:

Familiarity with containers and service communication technologies such as Docker, Kubernetes, and gRPC
Good working knowledge of both SQL and NoSQL databases, such as PostgreSQL, MySQL, DynamoDB, and an understanding of when to apply each

A solid understanding of continuous integration and continuous delivery (CI/CD) pipelines, and experience automating build, test, and deployment processes
Appreciation for modern DevOps practices, including infrastructure as code, observability, and production reliability
Good data literacy and experience with data warehousing or analytics solutions such as Databricks and Redshift
