About this role

In this role, you'll have significant ownership of your work, make impactful decisions daily, and report directly to the founders. This is a full-time remote position open to candidates in all timezones.
You’ll be responsible for expanding our product offering, finding solutions to things that aren’t working, and solving complex problems in logistics and supply chain. As one of our first product hires, you'll learn the ins and outs of a fast-growing SaaS product.
Here are your daily tasks in this job:
  • Independently manage projects from initial, rough designs to final implementation, including creating task lists in Linear, breaking down PRs into manageable, deployable code segments, testing in staging, deploying to production, and monitoring app performance post-deployment.
  • Prioritize and handle timely dependency upgrades in our applications with the same enthusiasm as greenfield projects, recognizing their importance in maintaining app security and enhancing user experience.
  • Assist our incredible support team with merchant questions in Slack and take pleasure in providing solutions.
  • Effectively communicate your progress and collaborate on problem-solving using digital tools like Slack and GitHub PRs.

  • Adapt to changing priorities and manage multiple tasks simultaneously.
  • Stay calm under pressure, especially when faced with multiple Rollbar errors, a full Sidekiq queue, or app downtime alerts.
  • Be comfortable working from home, using Slack as our main form of communication.

Qualifications

  • 4+ years of experience with Ruby on Rails
  • Experience with React, including hooks and context APIs
  • Experience with Shopify REST and GraphQL APIs is a plus
  • Experience with Shopify CLI and Theme app extension development is a plus
  • Familiarity with Rust is a plus

Our stack

  • Ruby on Rails
  • PostgreSQL
  • React
  • Shopify's Polaris design system
  • Redis for caching and background queues
  • Sidekiq for background processing
  • Heroku for application hosting

Who you are

Experience is key in this role. We’d love to know the extent of your experience with Rails and React as a combined tech stack. Can you provide insights into how you've set up Rails and React projects in the past? Are there any specific projects that could serve as a testament to your skills and capabilities?
We're particularly interested in your experience with Shopify API, Shopify CLI, or GraphQL API. Even if these experiences are not part of your repertoire, we value your expertise with integrations on other platforms. If available, we’d love if you can share any public app or API documentation from those platforms.
Beyond technical expertise, success in this role means embodying these three core values:
  1. Resourcefulness: You are relentlessly resourceful, always finding a way to achieve the highest standards of quality. You know where to look and whom to consult when faced with challenges, understanding that we always support each other.
  2. Ownership: You take complete ownership and pride in your work. This means deeply understanding our users' problems and how new features or updates affect them.
  3. Communication: You effectively communicate your progress, challenges, checklists, and pull requests, detailing them in Linear or GitHub PR descriptions to keep the rest of the team informed. Effective communication is crucial in our fully remote and asynchronous team environment.

If so, awesome! Keep reading. If not - no worries, perhaps we'll cross paths in the future.

About the job

With the help of our small team, (and some awesome team members at Thoughtbot), we've built an amazing Shopify SEO platform on Rails that has scaled wonderfully so far. To give a small indication, we process roughly 20-30M Sidekiq Jobs per day and are adding 8-10M db rows per day.

How are we different?

We might lose you here :)
  • We believe in writing Rails in a particular style, sticking close to standard and general Rails best practices. 
  • If a feature takes our competitors 8 weeks to build, we build a solid MVP in 8-10 days. We utilize the 80/20 principle to focus on what matters and just ship. Of course, we look at the usage metrics, then come back and complete the other 20% over time.
If this sounds like your style, we'd love to chat.

What will you be responsible for?

  • Development of our Ruby on Rails monolith.
  • Write high-quality, clean, and scalable code following best practices and design patterns
  • Write and maintain unit tests, integration tests, and end-to-end tests to ensure the reliability of the application
  • Perform debugging and troubleshooting to identify and fix issues promptly
  • Collaborate with teams to ensure smooth deployment and continuous integration processes and participate in configuring and maintaining the deployment pipeline and monitoring systems

Who you are

  • You’re self-driven and prefer working autonomously with limited guidance
  • You’re dependable, reasonable and trustworthy, with proven sound judgment
  • You can operate in a high-octane environment 
  • You utilize the Pareto Principle (80/20)
  • You prefer 5 minute daily standups vs long drawn out meetings 
  • You have a profound passion for Rails best practices

Requirements

  • 6+ years of professional software development experience with Ruby / Ruby on Rails
  • Deep knowledge of working with the Shopify app ecosytem
  • In-depth knowledge of database systems, particularly relational databases (e.g., Postgres, Sidekiq and Redis)
  • The ability to adjust to our high octane workflow. One of our core values is to create what works in its simplest form and iterate based on metrics and feedback. We don't have long release cycles 🤗
  • The ability to work in EST or PDT time zone, or at least overlap by 5 hours
  • Ability to write efficient and optimized code, following best practices and design patterns
  • Strong analytical and problem-solving abilities to tackle complex technical challenges
  • Excellent communication skills to effectively collaborate with cross-functional teams, including product managers, designers, and other engineers

❤️ Things we love

  • Living by our GAINS core values of Growth Mindset, Analyze Before Assuming, Iterate & Improve, Nurture Relationships, and Scrappy.
  • Helping over 1.4M Shopify merchants who have installed our software
  • Having a stress free work environment!
  • Being a 100% remote & 100% global team! 

🤮 Things we avoid

  • Micro-managing
  • Egos
  • Drama

Salary

Salary is negotiable and based upon experience. Everyone should earn what they feel is fair. This is a remote, full-time role (40+ hours/week).
Does this sound like you would be a good fit? Please complete the application form with a quick loom video about why you think you’d be a good fit, and we'll be in touch.
Thank you!

Our UI updates in near real-time and is written in LESS/CSS (with flexbox and grid layout) using CSS modules and takes advantage of fun technologies like Websockets and WebRTC. We house our design system in Storybook.
We care about performance (e.g. route-based code splitting), maintainability, and testability of our frontend code. We sweat the UI/UX details and work collaboratively with the Product team throughout the design process. This means diving into lo-fi wireframes, and communicating continuously when those ideas are brought to life using Figma and code.
Our frontend app is built on top of our REST API & GraphQL endpoints. Our backend tech stack consists of Python/Flask, MongoDB, Postgres, Elasticsearch, and Redis. We run our services in Docker on AWS.
We ❤️ open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check our projects such as react-custom-scroller, use-infinite-scroll, use-abortable-effect, and smart-tooltip-delay or insights from our day-to-day work on such as Highlights From a Complex Downshift.js Refactor, A Case Study in"Reactizing" a Complex Backbone View, and Finding the cause of a memory leak in Jest tests.

You should have senior level experience (~5 years) building modern frontend applications in JavaScript, HTML, and CSS, with at least 3 years of that experience using React.
You should have significant experience designing, debugging, and optimizing frontend applications to make them fast and reliable. You have significant experience with REST APIs and thoroughly understand HTTP requests. You have experience participating in code reviews and providing overall code quality suggestions to help maintain the structure and quality of the codebase.
You should have great product sense and be able to think through user experience issues before diving into the code, and you exhibit a love for great UI.
You’re comfortable working in a fast-paced environment with a small and talented team where you're supported in your efforts to grow professionally. You are able to manage your time well, communicate effectively and collaborate in a fully distributed team.
Note: this role requires you to be located in an Americas time zone. If you're not located in one of these time zones, check out our other posting here

Sporty's sites are some of the most popular on the internet, consistently staying in Alexa's list of top websites for the countries they operate in In this role, you’ll be responsible for developing microservices in a distributed deployment environment with an emphasis on containerisation with Docker and K8S. You won’t just be writing simple CRUD applications, but instead will be working on the core logic of complex systems that are accessed millions of times a day. We wrote our system from scratch about 3 years ago, so you’ll be working with the latest technology and won’t have to worry about decades old legacy code. A willingness to work in Springboot is fine - as long as you are willing to learn and have demonstrable experience in an object-oriented programming language. Our Stack (we don't expect you to have all of these)
