The beautiful tip of the iceberg
Most of what we build you'll never see. This is the part you can.

Own the Azure estates behind our clients' ASP.NET Core and Blazor systems
Most of what we support was built by someone else. When we take an estate on, somebody has to understand it end to end, decide what is safe, what is fragile and what it should become, and then own that design for years. That is this role: the architect who signs off every Azure design we deliver, hands-on with a senior .NET team.

What you will work on
Azure designs, reviewed
Designs for ASP.NET Core and Blazor workloads against the Microsoft Well-Architected Framework: reliability, security, cost, operational excellence, performance.
Discovery of inherited estates
Code, infrastructure, integrations and security posture, producing a written report, a severity-rated risk register and costed options.
Migrations that keep the lights on
Windows Server and SQL Server workloads reaching end of support moved onto supported platforms or Azure PaaS, release by release.
Identity, security and DR
Networking, Key Vault, backup and disaster recovery with agreed RTO and RPO, and the runbooks that prove they work.
Everything as code
Bicep or Terraform, Azure DevOps pipelines and blue-green release patterns, so every estate can be rebuilt from its repository.
Quarterly roadmaps
What is reaching end of support, what it costs to move, and what to leave alone, explained to a finance director.
Held and current on the day you apply, with its prerequisite AZ-104. Every engineer applying for a role at Assemblysoft needs a current Microsoft Azure certification, and we verify it on Microsoft Learn or Credly before the first conversation. Include a link to your transcript or badge with your application.

- Microsoft Certified: DevOps Engineer Expert (AZ-400): Preferred; funded within your first year if not yet held.
What we need from you
- A current Microsoft Certified: Azure Solutions Architect Expert (AZ-305) and its prerequisite Azure Administrator Associate (AZ-104), with proof of both included in your application.
- 7+ years in software engineering with at least 3 years designing and running production workloads on Azure.
- A hands-on ASP.NET Core background: you can read the code you are architecting for and review a pull request.
- Security and governance depth: MFA and least privilege, Key Vault, Defender, policy, and the evidence an auditor asks for.
- Cost awareness: designs that show their monthly figure, and the judgement to right-size rather than over-build.
- The ability to explain a design to a finance director and defend it to a security team.
Nice to have
- Microsoft Certified: DevOps Engineer Expert (AZ-400); Cyber Essentials Plus or ISO 27001 assessment experience.
- Blazor and .NET Aspire familiarity; SQL Server performance and migration to Azure SQL.
- Experience leading a supplier transition or a system takeover from an outgoing team.

Expert
Azure Solutions Architect Expert
