Full Stack Developer – Long-Term / Primary Developer

We’re looking for a talented Full Stack Developer to become our primary developer and work with us long-term. This is not a one-time freelance project.

About Us

We are a fast-growing cleaning company with a much bigger vision: build a technology-driven cleaning company that can scale to locations nationwide over the next 5–10 years.

Our website and internal systems are fully custom-built. Our current stack includes:

- Next.js
- React
- TypeScript
- Node.js
- Tailwind CSS
- Git
- Custom CMS
- Custom website & SEO editor
- Booking system
- Admin dashboard

Beyond our core website, we’re developing Flasha, our internal software and AI-powered platform designed to automate and improve different areas of our business. As we grow, we plan to continue building new software, AI tools, automations, integrations, and internal systems.

Our goal is to find one primary developer who understands our entire technology ecosystem and can grow with the company over the long term.

First Priority: Technical SEO

Your first priority will be auditing and improving our existing SEO implementation.

A significant amount of our SEO infrastructure is already built, including a custom SEO editor and dynamic location pages. However, some of our location pages are not being indexed properly by Google.

We need someone who can determine exactly why and fix the underlying technical issues.

You will

- Audit our existing SEO implementation
- Diagnose indexing and crawlability issues
- Fix technical SEO problems
- Review sitemap, robots.txt, canonical tags, metadata, structured data, and internal linking
- Ensure our architecture follows technical SEO best practices
- Make sure our SEO infrastructure is scalable

Once the existing system is working correctly, we’ll look at expanding our location architecture so we can efficiently create and manage counties, cities, towns, and eventually thousands of SEO-optimized location pages through our custom CMS. Long-Term Role

After the initial SEO work,



you’ll become involved across our technology platform, including:

- Website development and improvements
- CMS development
- Flasha and other internal software
- AI features and automations
- API integrations
- Admin and operational tools
- Performance optimization
- New customer-facing features
- Building new products and systems from the ground up

We’re looking for someone who enjoys building, problem-solving, and thinking through how technology can improve a real operating business, rather than simply completing assigned tickets.

How We Work

This is a highly collaborative role.

If you become our long-term developer, we’ll typically have 1–3 meetings per week to review progress, discuss priorities, brainstorm ideas, and plan upcoming features.

I also frequently use Claude to prototype ideas, features, and workflows before development, so being comfortable working alongside AI development tools is a plus.

Our previous developer recently accepted a full-time position elsewhere. He will provide a complete handoff of the existing codebase and will be available to answer questions during the transition.

What We're Looking For

Strong experience with

- Next.js
- React
- TypeScript
- Node.js
- Tailwind CSS
- Git
- APIs and third-party integrations
- Full-stack web application development

Strong technical SEO experience is a major plus, particularly with:
- Google indexing and crawlability
- Programmatic SEO
- Dynamic/location pages
- Site architecture
- Structured data/schema
- Core Web Vitals
- Large-scale SEO architecture

Who We're Looking For We’re especially interested in someone who wants more than another short-term development project.

We want someone who can learn our business, understand our entire codebase, contribute ideas, take ownership of the technology, and become our long-term primary developer as our company grows.

If you enjoy building products, solving real business problems, working directly with founders, and want the opportunity to help build the technology behind a company with nationwide ambitions, we’d love to hear from you.
