Main Street is hiring a Full Stack Engineer who will help design our technical architecture and build solutions that help business owners become entrepreneurs. Apply if you are excited about creating a platform for true entrepreneurship. 

As an early hire on the core team, you’ll work on shaping projects, big and small, over short three week sprints. We’re a small team, but we get a lot of features shipped. You would be responsible for driving full-stack projects from prototype to finished stage with a lot of autonomy and creativity. This is an exciting time to join the team. We've found solid early traction, have strong basic foundations and are pushing aggressively into some incredible new feature builds. We have a small team, so you can make an incredible impact on our product very quickly. 

Responsibilities:

• Own the design of the overall architecture of the web application
• Implement a robust set of services and effective APIs to power the web application
• Build reusable and manageable code and libraries for future use
• Optimize the application for maximum speed and scalability
• Translate UI/UX wireframes to visual elements
• Develop and handle well-functioning databases and applications
• Test software to ensure responsiveness and efficiency 
• Troubleshoot, debug and upgrade software

Experience:

• Proven expertise in shipping features in Ruby on Rails. Strong background in Ruby on Rails, HTML, CSS and JavaScript
• Strong experience in driving thought leadership and technical architecture
• Experience with mentoring juniors in the team

You are a fit if :

• You are a skilled coder. We need candidates with a strong history of shipping features in Rails with clean maintainable code. 
• You are a good communicator and a really good writer. Since we are async and remote most of our work is written. You'll need to be able to proactively communicate in concise, clear, simple writing.
• You are an expert project manager. You need to be able to break down a large, complex business deliverable into executable pieces that can be managed as individual user stories. You need to be able to keep a project on track, and cut scope when needed.
• You don't need babysitting and are a Manager of One. We love people who have started companies or have freelanced in the past. You take ownership and take things across the finish line. Especially in our remote async approach, you'll need to be intrinsically motivated and keep your  projects on track.
• You have strong business and product acumen. This job isn't just writing code, we solve real business problems for real people. That means you need to be able to look beyond the user story, have empathy for our end users and solve real problems for them.

About Main Street:

We're solving a problem that 62% of Americans have

62% of Americans last year thought about starting a business. The #1 reason they didn’t was because they didn’t know where to start. Currents options are:

1. Going independent which is risky: no support or direction
2. Paying a franchise which is expensive:  franchises charge $100K+ fees to get started, take 10% of topline revenue, don't provide marketing support or technology

The market we're going after is bigger than e-Commerce

We’re disrupting the $2.3T franchise industry by removing the franchise fee and offering a tech-enabled franchise like product.

We’re starting with home painting where our biggest competitor is https://certapro.com/">CertaPro a $550M revenue franchise (1% market share) before quickly taking on https://www.neighborlybrands.com/our-brands/">Neighborly Brands as we expand categories (pest control, lawn care, etc.).

As we expand categories, our customer does not change

Our customer is an aspiring business owner, like https://www.linkedin.com/in/nicklaforest">Nick or https://www.linkedin.com/in/hardin-h-hawes-9ba6a72/">Hardin who doesn't care what type of business they start, as long as it is profitable. Our customers are not actually the one painting houses or completing roofing jobs, rather they are the one that hires people to do the job. Our customer has years of experience in sales and general management, which makes them suitable for any type of business — which is why as we expand to 100 categories, our customer does not change.

Our solution is an end to end platform to help you start, grow and run a business
