Job description

We are looking for a strong Senior Front End Engineer who has strong experience with React. You will be a key member of our small frontend development team making important technical decisions.

If you have experience with Scrum and can lead a small group of developers, that is a HUGE bonus. If you are a ‘uber developer’, you will move to the front of the line. Essentially, ‘uber developer’ is a jack of all trades who can do a little bit of everything.

In addition to being a developer, this person is also a software architect and can help with some high‑level software design decisions. We also need the uber developer to do code review, provide some technical guidance to the junior developers, help do some mentoring, support, and maybe a bit of training.

Work with design and other teams to develop new customer-facing features and maintain existing ones.

• Create libraries, components and tools to ensure maximum performance with a top‑notch user experience.
• Improve development experience to delight your teammates.
• Think like a product owner: what will delight users? What are the acceptable risks?
• Help colleagues review and test code.

What you will do:

• Build and maintain frontend architecture.
• Collaborate with backend engineering, product, and design teams to write, test, and deploy code.
• Create new and innovative features for our users.
• Optimize pages for maximum speed.
• Solve problems creatively and efficiently.
• Steer architectural discussions and build consensus among team members.
• Help drive best practices, collaboration, and process improvements.
• Diagnose and fix bugs and performance bottlenecks.
• Maintain code and write automated tests to ensure the product is of the highest quality.
• Mentor and coach fellow teammates.

What You’ll Need:

• Significant production React or React Native experience on a medium to large scale application.
• Demonstrated experience mentoring other engineers and setting team best practices.
• Ability to write clean and well‑tested TypeScript code.
• Passion for doing the right things, collaborating, and team building.
• Excellent verbal and written communication skills.
• Are you able to work the hours of Mon-Fri, 9 AM to 6 PM, Eastern Standard Time?
• Are you able and willing to work outside of traditional local hours, if need be?
• What is your level of English proficiency? What is your level of English proficiency in the CEFR scale or equivalent?
• On a scale of 1-10, with 10 being expert, could you rate yourself on a) React, b) JavaScript, and c) RestFUL API?
