Senior Frontend Developer

| Chicago

Are you looking to join a positive, diverse team to build beautiful and dynamic applications that tackle complex problems for real people?


DRIVIN is growing engineering teams across our Chicago office. We are a big data, analytics, and machine learning company innovating in the used car industry. The product engineering teams create applications and tooling for the largest automobile dealers in the industry like Honda, Toyota, GM, and Audi. We are passionate about what we do and move fast together.


As a Senior Web Software Engineer you’ve had experiences delivering real-time, data-driven web applications and supporting them in production. You can explain your debugging process and how you tackle technical debt. You are comfortable learning and evaluating new languages and libraries.


We expect senior engineers to drive a culture of quality, mentor their piers at any level, accept feedback and continue to grow their own skillset, and drive the design and implementation of complex software systems through careful planning and scoping practice.


You are able to demonstrate discipline in promoting and adhering to style guides and developing best practices. You are deeply committed to refactoring and testing your code while keeping other developers in mind. You enjoy conducting peer reviews in the spirit of constructive collaboration. You also have hobbies and interests outside of work!


Your main responsibilities will be the implementation and maintenance of data-rich UI applications across desktop and mobile devices. You will communicate often with middleware (Java) developers, data engineers, QA, and product owners to set and manage expectations. Consistency is key.


We are highly collaborative, creative, and open-minded. We build things on a modern tech stack using Amazon AWS. Some tools we use include React, Redux, Webpack, and D3.


We value an inclusive team environment which supports us in our differences. Our hiring process celebrates candidates from diverse backgrounds. We believe that demonstrated excellence is a transferable skill. Tell us what you've achieved!

An Insider's view of KAR Global

What's something quirky about your company?

Our culture is more like a family than colleagues. One of my favorite aspects about this office is our Parents-designated Slack channel—an online team collaboration site. It is a great reminder we aren’t just employees, but we can be moms and dads at work, shamelessly sharing fun stories about our personal lives.


Senior Product Manager

What's the biggest problem your team is solving?

KAR Global’s DevOps teams are always solving unique problems, but tackling complexity is the real challenge. We’ve found that meaningful solutions come when we don’t focus on fighting fires reactively and instead work collaboratively on building proactive frameworks and implementing forward-thinking processes.


Jr. DevOps Manager

What does your typical day look like?

We start the day with a 15-minute huddle to talk about progress from the day before, the day’s plan and barriers to success that need to be addressed. This gives us a clear understanding of our priorities for the day. Our teams are dynamic, so every member of our project team works together each day to discuss design approaches and share ideas.
