Senior Full-Stack Developer (CRM / SaaS / Web App) – Part Time / Long Term

We are a U.S. based company looking for a senior software developer to help continue development of our internal CRM / business management software.

This is NOT a beginner role.
We need someone experienced building real software systems, not just websites.

About the software:

We built our own CRM from the ground up similar to Pipedrive.
We want to continue developing it into a full business management platform similar to JobNimbus where we can run our entire company from one system.

The software includes:

* Sales pipeline
* Job pipeline / production tracking
* Customer management
* Scheduling
* Integrations
* Automation
* Reporting dashboards

We are currently using Cursor AI to help write code, but we need a senior developer to help design and build the system correctly.

Required skills:

* Strong experience with full-stack development
* Experience building SaaS or CRM software
* Database design (SQL / Postgres / MySQL)
* API development
* Backend development (Node.js, Python, or similar)
* Frontend development (React, Vue, or similar)
* Experience working with existing codebases
* Ability to plan software architecture

Bonus skills:

* Experience with CRM systems
* Experience with contractor / job management software
* Experience with AI coding tools (Cursor, Copilot, GPT, etc.)
* Experience with cloud hosting (AWS, Vercel, DigitalOcean, etc.)
* Experience with automation / integrations

Work type:

Part-time to start (10–20 hours per week)
Long-term role if good fit

Salary:

$1,000 per month depending on experience

To apply, please include:

1. Examples of software you built
2. Your experience with CRM or SaaS apps
3. What languages you use most
4. Your monthly salary expectation
5. Your availability

Important:

We are only looking for senior developers with real experience building software platforms.
If you have only built websites or small scripts, this is not the right job.
