???? Monarch Investment & Management Group

???? We’re actively interviewing and ready to hire NOW — apply ASAP!

???? Compensation & Benefits

  • Up to $90K Annually DOE
  • 401(k) retirement plan with up to $4,000 annual company match
  • Paid training and professional development programs
  • Tuition reimbursement program
  • Paid Time Off:
    • 80 hours during Year 1
    • 120 hours during Years 2–4
    • 160 hours after 5 years
  • 8 paid holidays plus 2 paid half-day holidays or work anniversary of

  • Employee referral bonuses ranging from $500–$1,000
  • Employee discounts through major retailers and services
  • Complimentary skiing at Monarch Mountain

⚡ Why This Role Stands Out:  This isn’t a “sit back and be told what to do” kind of job. We’re looking for someone curious, scrappy, and motivated—whether you’re early in your career or already have experience.

You’ll thrive here if you:

  • Take initiative and don’t wait for perfect instructions
  • Like figuring things out—even when it’s messy
  • Are excited about using AI tools to build smarter, faster solutions
  • Enjoy solving real problems, not just completing tickets

???? AI-Driven Development Environment: AI isn’t a buzzword here—it’s part of how we build.

You’ll:

  • Leverage tools like Claude Code and other AI platforms
  • Prototype quickly and iterate in real time
  • Turn rough ideas into functional solutions
  • Work on projects without a rigid roadmap

???? Example: Build and connect a regional marketing/lead-gen platform tied into leasing systems—figuring out integrations, automation, and UX along the way.

???? What You’ll Be Doing:

  • Support, maintain, and improve internal applications
  • Build automation tools and lightweight applications
  • Assist with API integrations (including Yardi and other systems)
  • Experiment with AI to streamline workflows and development
  • Troubleshoot issues and optimize system performance
  • Collaborate with senior developers while owning your work

???? What We’re Looking For: We are open to entry-level candidates with strong foundational skills as well as more experienced developers.

Required: 

  • Experience (professional, academic, or internship) in software or application development
  • Exposure to Python, C#, Node.js, or similar
  • Basic understanding of APIs, SQL/databases, and integrations
  • Familiarity with frameworks like Django, Flask, or .NET Core
  • Experience with Git/version control

Nice to Have: 

  • Cloud or serverless exposure (Azure, etc.)
  • Basic front-end skills (HTML, CSS, JavaScript)

???? What Will Make You Stand Out:

  • Self-starter mentality — you take ownership and run with ideas
  • Comfortable learning as you go and adapting quickly
  • Interest in or experience with AI-assisted development
  • Problem-solver who doesn’t need a perfect roadmap
  • Driven to build, test, fail, learn, and improve fast

???? Apply Now — We’re Moving Fast: If you’re ready to learn quickly, build real solutions, and grow your career, we want to hear from you.

???? Apply today to join Monarch Investment & Management Group
