• Technical Leadership: Serve as a technical leader within your team, guiding architectural decisions and mentoring junior developers.
• Cross-Functional Collaboration: Work directly with the Product team and customers to understand requirements and implement them as working software.
• Agile & CI/CD: As a team member you will actively participate in the Agile software development lifecycle. You will contribute to test automation, define and develop infrastructure-as-code, and ensure robust, automated builds and deployments at an enterprise scale.

Who You Are:

• A Hands-On Developer: You are a highly skilled, hands‑on developer with a strong foundation in object-oriented design and development.
• A Technical Leader & Communicator: You have a history of leading technical initiatives and are an effective teacher, able to explain complex concepts to both technical and non-technical colleagues.
• A Pragmatic Problem‑Solver: You understand and apply Agile principles in a pragmatic way and have a track record of learning and implementing new software development practices, tools, and languages.

Skills & Experience We Value:

Required Experience:

• Proficiency in C#.
• Relational databases and SQL.
• Cloud architecture and development (Azure preferred).
• Infrastructure-as-code tools and modern source control and build systems such as Terraform, GitHub, and GitHub Actions, respectively.
• .NET 8 or above, .NET Framework 4.8, WCF, and Entity Framework 6.
• Implementing distributed systems incorporating Docker, Kubernetes, and related cloud infrastructure.
• Distributed messaging patterns (e.g. Saga, Outbox, CQRS, and Event Sourcing).
• Observability tooling (e.g., Datadog, Application Insights, OpenTelemetry).

Preferred Experience:

• Angular 2+.
• Azure messaging stack (e.g. Service Bus, Event Hubs, and Event Grid).
• Data warehousing concepts (star/snowflake schemas, dimensional modeling).
