Job description

Benefits:
  • 401(k)
  • Bonus based on performance
  • Health insurance
  • Paid time off

Company: Fletcher Group / Vibrant Building Technologies
About us We are a vertically integrated platform operating across luxury construction, real estate development, estate management, interior design, self-storage, and hardware technology (intelligent ventilation and air quality systems). The portfolio spans eight operating companies and a growing real estate footprint. We are building the internal software layer that will support the group as it scales.
The role We are hiring a junior backend developer to build the automation and integration layer that connects our operating companies โ€” project management, accounting, procurement, client communications, estate services, and the Vibrant product and subscription stack. You will work alongside senior operators and modern AI development tooling, shipping in short cycles and iterating based on real usage.
What you will build

  • Process automations that eliminate manual re-entry across QuickBooks, project management tools, CRM, and field systems
  • Payment and billing flows (Stripe, QuickBooks)
  • Notification infrastructure (OneSignal or equivalent) for client, crew, and internal alerts
  • API integrations with third-party platforms we already use โ€” our preference is to integrate existing tools rather than build from scratch
  • Internal dashboards and lightweight tools to replace spreadsheet-based workflows
Minimum requirements

  • Working knowledge of .NET (C#) and Python for backend development
  • Experience building and consuming REST APIs
  • Comfort with at least one major database (Postgres, SQL Server, or similar)
  • Ability to work on code that handles payments and customer data responsibly โ€” i.e., you take security seriously
  • Proficiency with AI coding tools (Claude Code, Cursor, Copilot) as part of your daily workflow
Preferred

  • Experience with notification platforms (OneSignal, Twilio, SendGrid)
  • Payments integration experience (Stripe, QuickBooks API)
  • Familiarity with secrets management, secure coding practices, and basic security review processes
  • Prior experience at a startup or small team with end-to-end feature ownership
Compensation: $55,000-$80,000/year base salary with a path to equity participation for strong performers. High performers have historically moved up quickly within the group.
To apply Send a resume and links to relevant work โ€” side projects, GitHub, prior contract work, or automations you have built in past roles. A short note describing a specific integration or automation you shipped, including what went wrong and how you fixed it, is more useful to us than a standard cover letter.
