A web development startup is a new business that focuses on creating and maintaining websites or web applications for clients or users. These startups typically offer services such as designing, coding, and optimizing websites, as well as developing custom web-based solutions.

Web development startups can range from small teams to larger companies, and they may work with businesses of all sizes to help establish or improve their online presence.

Re-posted 18 days ago

Job description

The Heroku Web Apps team is dedicated to beautiful, usable, and valuable web apps. We're highly collaborative, make decisions in minutes, and ship features in hours. We believe in getting customer validation early, verifying with real data, but also running with our gut.

The small team includes UI/UX design and product management, but everyone on the team is responsible for the success of our products, including that we're building the right thing in the first place, and that it's polished and beautiful when it's done. We're seeking a developer with a passion for UI/UX, great HTML/CSS/Javascript skills and that can own the entire stack of a Ruby on Rails app, including ongoing operations and maintenance. The ideal profile combines deep experience in full-stack web development with a strong computer science background.

You should be passionate about: User experience and goal-directed design Current Rails/jQuery best practices Style, presentation, and design You should be very strong on all of the following: HTML/CSS - not a web designer, but extremely good at implementing markup Javascript - including jQuery and cross-browser compatibility Ruby on Rails Performance optimization, SQL tuning, caching strategies Ability to own projects end-to-end Bonus skills: Async (e.g. Backbone.js, EventMachine, Node.js) HTML5 fanciness (e.g

websockets, canvas) Test Driven Development (TDD) Amazon Web Services (AWS e.g. S3, EC2) Having founded your own startup Attach a resume, but also include something about yourself in your message. Tell us why you love the product, why you want to work at Heroku, why you want this job, and why you're qualified

Use the resume to back yourself up. UI samples (or URLs) should be included. This position does require that you live in, or be willing to relocate to, San Francisco and that you're already legally able to work in the US - H1B quotas don't open up again until April.

If you're Canadian or Australian with a 4 year degree, we might be able to do something.
