Job description

Senior Applications Developer

• Hybrid contract to hire or contract opportunity
• Candidates must be local to the Twin Cities Metro area and willing to go into the office in Rosemount, MN.

The work

Our client builds the software Minnesota law enforcement runs on. Records management, data sharing between agencies, the integrations that let a deputy in one jurisdiction see what happened in another. When this software works, officers are safer and cases move. When it doesn't, people notice immediately.

This is a small, collaborative technology team inside a public-sector organization — you'll know everyone's name and every system they run. Mission-driven work, modern tools, and a lot of hands-on problem solving.

Be clear-eyed about the shape of this job: it's build and run. You'll write new features and you'll also keep production healthy, restore a database, and take the on-call phone. If you only want greenfield work, this isn't it. If you want to own systems end to end and see your work land with actual users, it is.

Intertech is managing this search on the client's behalf. We'll tell you who they are once we've talked.

What you'd own

• Full-stack development across .NET and React applications, plus scripting and older languages across an established estate
• Integrations— the interfaces and middleware moving data between internal systems, agency systems, and state partners. This is the heart of the role
• The reporting layer— you'd own reports and reporting products end to end: creating, converting, and maintaining them
• Production— deploy your own code, monitor servers, schedule backups, restore databases, patch systems
• Direct user work— troubleshoot with police departments and county staff, demo new functionality, train users, and write the documentation they'll actually use
• The Azure DevOps environment— you may administer the repo and work-item environment, not just commit to it
• Project definition— scoping, scheduling, and negotiating deliverables and timelines
• External representation— speaking for the organization with state agencies, consortiums, other government entities, and vendors
• Mentoringdevelopers and helping evolve the team's Scrum process
• A rotating24/7 on-callphone, shared with the team

What you need

• Bachelor's degree in Computer Science, Management Information Systems, Software Engineering, or a closely related technical field
• 5+ years professional experience with object-oriented and scripting languages
• Real depth inC#/.NETandSQL Server— production systems you've built and maintained, not just features
• Reactor comparable modern front-end experience
• Systems integration: APIs, interface design and implementation, middleware
• Azure— you've built and deployed there
• Source control management and clear separation of dev/test/production environments
• Agile experience, and the ability to explain the tools you actually used
• SQL query authoring and maintenance
• Comfort with non-technical users — explaining tradeoffs without condescension
• Self-motivated, sound independent judgment, minimal supervision
• Ability to pass a state background check and to obtain and maintain state certification

Preferred

• Public safety, criminal justice, or government systems experience
• Broader cloud platform experience
• Understanding of firewall and network communication between servers and integration points
• Business intelligence and reporting depth
• One-on-one customer work solving complex business problems
• Infrastructure as code (Terraform, Bicep)
• AI-assisted development in your daily workflow

Work environment and details

• Rotating 24/7 on-call duties, plus occasional work outside business hours to hit deadlines
• Office-based role;hybrid may be available with management approval
• Sedentary office work, extended sitting, ability to lift or move up to 25 lbs
• Changing priorities and detail-heavy work under deadlines
