Senior C# Developer: Explorers/Identity Resilience

About the Role

We're looking for a Senior C# Developer to join our team, which focuses on two main areas:

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 We 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, refactoring safely
• English for daily work in an international team
• Nice to have: PowerShell module development, Protobuf, Linux, hypervisor APIs

What You'll Get

• 25 vacation days, 4 sick days, 21 paid medical leave days, plus 4 extra global VeeaMe Days for self-care and 24 paid volunteer hours annually through Veeam Cares
• Premium private medical insurance for employees and dependents
• Daily meal vouchers for restaurants and groceries (180 CZK per working day)
• Flexible cafeteria platform with thousands of lifestyle benefit options
• Multisport Card for gym and wellness, with family add-on options
• Annual public transport reimbursement up to a set limit
• Corporate mobile plan with optional family tariff
• Opportunities to learn and grow through on-demand libraries (LinkedIn Learning, O’Reilly), mentoring, workshops and learning events like our annual Global Day of Learning

Please note: If the applicant is permanently present outside of the Czech Republic, Veeam reserves the right to refuse to consider the application for a job. A remote job is only possible in case the employee is located in the Czech Republic.
