How to Apply for Principal Software Engineer - C# / .NET
at Re:Build Manufacturing
🏢 About Re:Build Manufacturing
Re:Build Manufacturing is uniquely positioned as a family of industrial businesses revitalizing U.S. manufacturing through technology and strategic acquisitions. They combine deep engineering expertise with operational excellence to tackle complex systems across aerospace, defense, healthcare, and other critical industries. This offers the rare opportunity to apply cutting-edge software development to tangible manufacturing challenges with national impact.
About This Role
As a Principal Software Engineer, you'll architect and build cloud-based applications using C#/.NET and AWS to support Re:Build's manufacturing operations and member companies. This role involves designing distributed systems and microservices that directly enhance manufacturing efficiency, product development, and automation. Your work will shape the technological backbone enabling America's next-generation industrial company.
💡 A Day in the Life
A typical day involves collaborating with engineering teams to design and review C#/.NET microservices architecture on AWS, optimizing cloud infrastructure for manufacturing applications. You might mentor engineers on best practices, troubleshoot distributed system issues, and work with cross-functional teams to align software solutions with operational manufacturing needs. The role balances hands-on coding with architectural decisions and team leadership.
🚀 Application Tools
🎯 Who Re:Build Manufacturing Is Looking For
- A backend expert with 10+ years building scalable cloud applications in C#/.NET, specifically with microservices and distributed systems architecture.
- Deep hands-on experience with AWS serverless (Lambda, Step Functions), containers (ECS/EKS), CI/CD pipelines, and modern cloud services relevant to manufacturing or industrial applications.
- A proven mentor who has actively shaped engineering culture, processes, and team development in previous roles.
- Someone passionate about applying technology to solve real-world industrial problems, with interest in manufacturing, automation, or complex systems.
📝 Tips for Applying to Re:Build Manufacturing
Quantify your impact: In your resume, highlight specific projects where your C#/.NET and AWS expertise improved system scalability, reduced costs, or enhanced reliability in cloud-based applications.
Showcase manufacturing/industrial relevance: Even if not in manufacturing, emphasize experience with complex systems, data-intensive applications, or domains with high reliability requirements (e.g., finance, healthcare, logistics).
Demonstrate mentorship and culture shaping: Provide concrete examples of how you've mentored engineers, improved processes, or contributed to engineering culture beyond just coding.
Tailor to Re:Build's mission: Explicitly connect your skills to their goal of revitalizing U.S. manufacturing—explain how your tech expertise can supercharge manufacturing operations.
Highlight AWS serverless and containerization: Detail specific implementations using AWS serverless architectures and containers, as these are explicitly mentioned in the requirements.
✉️ What to Emphasize in Your Cover Letter
["Your passion for applying technology to solve real-world industrial challenges, aligning with Re:Build's mission to revitalize U.S. manufacturing.", 'Specific examples of architecting and scaling C#/.NET microservices and distributed systems on AWS, particularly in complex or regulated environments.', 'Experience mentoring engineers and contributing to engineering culture, emphasizing leadership beyond technical skills.', 'How your cloud and backend expertise can directly support manufacturing operations, automation, or product development at Re:Build.']
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Re:Build's member companies and their specific industries (aerospace, defense, healthcare, etc.) to understand the domain challenges.
- → Their recent acquisitions and how they integrate technology into manufacturing (look for press releases or case studies).
- → The company's stated focus on 'enabling technologies' and 'operational superiority'—think about how software enables those goals.
- → U.S. manufacturing trends and challenges where technology plays a key role (automation, IoT, supply chain resilience).
💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Focusing only on coding skills without demonstrating experience in system architecture, cloud design, or mentorship.
- Generic cloud experience without highlighting specific AWS services (serverless, containers, CI/CD) mentioned in the job description.
- Ignoring the manufacturing/industrial context—failing to connect software skills to real-world applications in complex systems.
