About The Simple Investor

The Simple Investor is a leading real estate investment and property management firm based in Ontario, Canada. For over 15 years, we have helped investors grow and manage their portfolios by making real estate investing simple, transparent, and effective. Our integrated approach combines strategic acquisition with professional property management services to deliver consistent, long-term value.

The Role

We are seeking a Full Stack Developer (Intermediate) to support the internal systems and web experiences that help our team operate efficiently and help investors move through our process smoothly. You will report directly to our lead developer and collaborate closely with Operations, Marketing, and leadership.

This is a hands-on role where you will work across a few different web applications and integrations. Priorities can shift quickly, so we're looking for someone who can take ownership, communicate clearly, and ship high-quality work with minimal supervision.

If this sounds like you encourage you to apply and become part of a company dedicated to simplifying real estate investment.

• Take ownership of at least one meaningful feature end-to-end (planning, development, testing, and release) within the first 45 days
• Assume responsibility for a core product area or key integrations within the first 90 days, consistently delivering work that reduces the overall load on the development team

• Backend development experience with Node.js
• Familiarity with PHP or the ability to work with legacy codebases

• Experience with CI/CD pipelines (e.g., GitHub Actions, CodePipeline)
