Job description

Arise® connects enterprises with a global network of entrepreneurial service partners. You will own the architecture of the agent and client global websites and mobile apps — the systems our partners use every day.

This is a hands-on architecture role, not an advisory one. Roughly 60% of your week is architecture: high-level solutioning and writing the solution stories your developers build from. About 20% is development sprint work in our .NET services, and 20% is production support — analyzing issues, writing solutions for the team, and coding the fix yourself when that is the fastest path. On-call support for production issues is part of the role.

Reports to: Senior Manager of Engineering

Team: Three engineers — two .NET, one mobile

Core hours: 7:00 AM – 1:00 PM US Eastern

Travel: None

What you'll do

• Own architecture across web, mobile, and integration platforms — web and mobile are designed in sync, so you will architect both even though you will code only in .NET
• Lead the modernization of legacy portals into scalable, cloud-native solutions on AWS
• Architect and develop enterprise portals using ASP.NET MVC and React
• Define architecture standards, coding practices, and governance; lead design and code reviews
• Design REST-based services, API governance, and integrations with enterprise platforms
• Mentor .NET engineers and build skill and growth plans for the team
• Look for ways to make development more efficient, including with AI tooling — we already use it and want to go further

What success looks like

• First 3 months: functional command of all Arise portals, websites, mobile apps, and .NET APIs; the agent registration and enrollment site upgraded to current React; performance and memory-leak work moving so the portals can migrate to AWS
• By 6 months: architecture options proposed for transforming the legacy portals into modern, cloud-enabled systems
• By 12 months: those modernized portals implemented, and growth plans in place for the .NET engineers you mentor

What we're looking for

• 10+ years of software development experience, with 5+ years in solution architecture or technical leadership
• Deep C# and .NET expertise — .NET Framework and .NET 8+, ASP.NET MVC, and Web APIs
• A track record modernizing legacy .NET applications at scale
• Microservices, event-driven design, REST APIs, and API gateway patterns
• AWS cloud architecture; SQL Server and Entity Framework; OAuth2, JWT, and SSO
• React and TypeScript
• Experience architecting both web and mobile applications
• Experience mentoring engineers
• Bachelor's degree in Computer Science , Engineering, or a related field, or equivalent practical experience

Nice to have

• Hands-on Flutter and Dart — a plus, not a requirement
• Salesforce or MuleSoft integration experience
• AWS Solutions Architect certification
• Experience with globally distributed teams and Agile/Scrum delivery
