In this role, you will lead the evolution of our application architecture while taking ownership of the full software release lifecycle-from core development and patching strategies to sophisticated installer packaging and deployment. This is a senior-level technical role that balances high-level architecture decisions with low-level release engineering. You will collaborate closely with QA and product teams to build reliable upgrade, migration, and rollback strategies, mentor junior team members, and drive CI/CD excellence. If you are a release-focused developer who understands the complexities of Windows environments and deployment automation, we want to hear from you. Key Responsibilities Development & Architecture Application Engineering: Design, develop, test, and maintain robust, high-performance applications using C# and modern .NET technologies (Framework and Core). Technical Leadership: Act as a senior contributor and technical mentor; conduct code reviews, influence architectural strategies, and drive technical decision-making. Release Engineering & Installer Packaging Advanced Packaging: Create, maintain, and troubleshoot complex MSI installers and bootstrapper applications utilizing tools such as WiX Toolset and Advanced Installer. Deployment Strategy: Design end-to-end upgrade, patching, rollback, and migration strategies. Develop specialized packages for hotfixes, upgrades, and silent installations. Pipeline Management: Build and manage CI/CD pipelines (e.g., GitHub Actions) and utilize PowerShell scripting to ensure reliable, automated deployment processes. Quality & Troubleshooting Production Support: Analyze and resolve complex production issues and installation-related roadblocks, ensuring software quality and release readiness. Continuous Improvement: Work in tandem with QA teams to ensure software quality and contribute to the evolution of release management standards. ## Related Videos - [Blazor Unleashed: The Future of .NET Web Development](https://www.wearedevelopers.com/videos/1564-blazor-unleashed-the-future-of-net-web-development) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Blazor – the new SPA Framework for everyone who hates JavaScript](https://www.wearedevelopers.com/videos/699-blazor-the-new-spa-framework-for-everyone-who-hates-javascript) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Why Attend a Developer Event in 2026?](https://www.wearedevelopers.com/magazine/688-why-attend-a-developer-event-in-2026) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
