Senior C# Developer: Explorers/Identity Resilience

Role overview Build and evolve recovery software that helps organizations restore databases or Active Directory environments after outages and other failures. The work spans customer-facing APIs, server-side orchestration, remote agents, and PowerShell tools. Recovery operations can run for hours, so systems must handle interruptions, cancellation, and failure reliably; the role also includes improving an established product codebase.

Responsibilities - Design recovery workflows across REST or gRPC interfaces, server orchestration, and agents running on target systems. - Develop PowerShell cmdlets with clear parameters, validation, and a consistent object model. - Add pre-run checks across service and agent layers to catch restore problems before execution begins. - Work with the internals of at least one recovery domain, such as SQL Server, Oracle, PostgreSQL, or Active Directory. - Manage long-running distributed sessions, including agent deployment, keep-alive, timeout, cancellation, and cleanup after failures. - Maintain integration tests and safely refactor existing code as the product evolves.

Requirements - Five or more years of commercial C# product development, with strong .NET, data structures, and algorithms knowledge. - Experience designing service APIs such as REST or gRPC, including attention to external consumers and backward compatibility. - Strong asynchronous and multithreaded programming skills, especially for long-running operations and session lifecycles. - Deep knowledge of either Windows Server and Active Directory or database recovery for SQL Server, Oracle, or PostgreSQL. - Ability to navigate unfamiliar, mature code and make changes safely. - English proficiency for daily collaboration in an international team.

Nice to have PowerShell module development, Protobuf, Linux, or hypervisor APIs.
