About the Role We're looking for a Senior C# Developer to join our team, which focuses on two main areas: * Active Directory Forest Recovery as part of Identity Resilience, which rebuilds an entire AD forest after a domain-wide outage or ransomware attack" * Veeam Explorers - granular recovery for SQL Server, Oracle, PostgreSQL, Exchange and SharePoint - where we expose browse and restore through REST and gRPC so they can be driven from the Web UI, PowerShell and automation Both are the same kind of system: a server orchestrating a remote agent via a versioned contract, running operations that can take hours and must survive failures at any step. What You'll Do Design and implement recovery flows end-to-end — REST and gRPC contracts, server-side orchestration, and the agent that executes on the target machine Build PowerShell cmdlets as a first-class product surface, with parameter validation and a coherent object model Design pre-flight validation that catches issues before a restore starts, across REST, server and agent layers Work close to what you're recovering: SQL Server, Oracle and PostgreSQL internals, or Active Directory — domain controller promotion, SYSVOL and NTDS, DNS, Kerberos, replication Manage long-running distributed sessions: agent deployment, keep-alive, cleanup on failure and timeout, and cancellation Own your integration test suite and keep it green Refactor a long-lived codebase as you go — this is a mature product, and improving what's there is part of the job Technologies W e Work With: C#, .NET, REST, gRPC / Protobuf, PowerShell, multithreading and async, Windows Server and Active Directory, Linux, MS SQL / PostgreSQL / Oracle, VMware and Hyper-V, Git, TFS, Visual Studio, Rider What You'll Bring 5+ years of commercial C# product development, with a deep understanding of .NET, data structures and algorithms Experience designing service APIs — REST, gRPC or similar — where consumers are external and backward compatibility matters Strong async and multithreading: cancellation, session lifecycle, hours-long operations Depth in at least one of: Windows Server and Active Directory administration or internals, or database recovery mechanics for SQL Server, Oracle or PostgreSQL Comfort in a large existing codebase: reading unfamiliar code,…
