Tell Me About My Job:

If you are considering this contract role, you are someone who is passionate about the front-end user experience and has a proven track record of delivering elegant, intuitive web-based UIs for enterprise applications. You enjoy coaching and guiding new and junior teammates to become thoughtful, self-starting contributors who have a growing impact on the organization.

As a contractor, you will help us evolve and maintain our product using React and TypeScript along with other front-end technologies. In this role, you will be a member of an agile product team tasked with optimizing the gas station supply chain, powered by AI and industry-shaking UX.

Our developers and designers are the driving force behind our product’s success and are very influential in decision-making. We hire creative people and give them the autonomy to do great work. We’re strongly against artificial separations of responsibility and throwing work “over the wall”; instead, we constantly optimize around the highest and best use of our resources.

This is a fixed-term contract for 9 months, with the possibility of extension based on performance and organizational needs.

You’re an Ideal Candidate If:

• You understand the power and challenges in the React ecosystem, including state management, component reuse, and performance.
• You have strong experience integrating REST APIs with UI.
• You are experienced with CSS and Less/SASS in modern JS frameworks.
• You have experience organizing and managing a reusable component library for a codebase.
• You are comfortable managing pull requests, utilizing code reviews as teaching opportunities, and handling git management and versioning.

Duties/Responsibilities:

• Implementing complex and data-intensive interfaces in a performant and maintainable way through React Hooks, Contexts, and modern libraries.
• Driving forward our TypeScript initiative and moving us towards 100% type coverage.
• Curating and maintaining a Storybook (component documentation) for the component library.
• Creating extensible and reusable components that provide significant value across all our products.
• Exercising creativity and challenging the status quo to enhance our front-end applications.
• Iterating with product owners and scrum masters to continuously improve the developer experience.
• Investing in and growing our frontend and software knowledge base, including technical documentation, setup guides, and architecture diagrams.
• Leveraging automation where it delivers value and reduces churn.

 

Nice to Have Experience:

• Experience with UI component libraries like Material UI or antd.
• Familiarity with AG Grid.
• Knowledge of @tanstack/react-query.
• FE DevOps skills, including Docker and GitHub Actions.
• Experience building and maintaining large-scale, enterprise SPAs.
• Experience owning and maintaining npm packages and dealing with the challenges of using them across multiple applications.
• Experience with modern testing frameworks (e.g., Jest, Cypress, Mocha, Chai).
• Experience with data visualization libraries (Google Maps, D3, Highcharts, or Nivo).
• An advocate for building beautiful, usable products, with a strong emphasis on design and user experience throughout the software lifecycle.
