What you will be doing:

Our Circuit Marketing Sites (CMS) team plays a crucial role in showcasing our products to the world. But right now, our marketing site isn’t keeping pace with our product innovations, and we’re looking for an experienced engineer to help us change that.

You’ll be responsible for owning entire pages and sections and translating design concepts into performant, SEO-friendly, and visually stunning experiences. There are no hard deadlines, no micro-management, and no layers of approvals—just the freedom to build high-quality web experiences at your own pace.

Once our core site is up to speed, you’ll have the opportunity to build mini-apps and interactive tools that capture attention, drive traffic, and generate leads. We love experimenting with creative ideas and pushing the boundaries of what’s possible.

Your typical day-to-day:

• Building high-performance marketing pages from Figma designs using Next.js, React and Tailwind.
• Owning projects from start to finish, ensuring a seamless blend of performance, aesthetics, and SEO best practices.
• Collaborating with our marketing design team to bring interactive and engaging web experiences to life.
• Making smart technical decisions—you’ll have full autonomy to implement new tools and technologies that enhance our site.
• Staying ahead of the curve by leveraging the latest web innovations (React 19, Next.js 15, etc.).
• Conducting code reviews and ensuring the highest level of quality in your work.

What you won’t be doing:

• Having lots of meetings. Expect ~one meeting per week. If you rely on frequent check-ins to stay on track, we’re not the right fit.
• Working to unrealistic deadlines. We optimize for quality and long-term progress, not burnout!
• Managing people. While you’ll share knowledge and manage your own projects, this is a hands-on individual contributor role.

We’d love to hear from you if you:

• Have 6+ years of experience in frontend development, with strong expertise in React, TypeScript, and modern full-stack meta-frameworks (e.g., Next.js, Astro, Remix, or similar).
• Like building fast, SEO-optimized, and visually stunning marketing websites.
• Understand performance optimization techniques, including server-side rendering (SSR) and static site generation (SSG).
• Are experienced working on public-facing marketing sites with a focus on performance.
• Work well independently and can figure things out, even when requirements change.
• Communicate clearly and enjoy working with designers to build the best websites possible.
• Can spot a simpler way to do something and aren’t afraid to suggest it!
• Are based in UTC-5 to UTC+2 time zones.
• Can speak and write in English at a professional level.

It would be nice if you have:

• An eye for UI/UX and animations , with experience bringing designs to life.
• Familiarity with Sanity.io .
• Experience with Next.js.
• Accessibility experience.

Who we are, what we do, and how it’s going:

Back in 2017, we saw an issue with last-mile delivery – it was too complicated and stressful for drivers. Circuit started a mission to change that by choosing to develop an app that put the driver, and their customers, first.

We were astounded by the response we received. Within our first year, we had almost 1,000 customers, $100k in ARR, and a team consisting of our two co-founders, Jack and Pol. With a lean team of ~40, we’ve grown to $25M ARR , helping over 100,000 drivers deliver more than 1 billion packages worldwide —about 20 every second!

Our Hiring Process:

Our hiring process for this role has five stages (if we include the 10-minute application!) and usually takes ~three weeks for the whole process. At every step, you will be able to ask questions of your own and make sure that we are the right choice for you.

Apply:

Upload your resume and fill out our application form. It takes about 10 minutes to complete, and we don’t ask you to repeat anything that’s already on your CV!

Meet our TA Manager: You’ll have a 45-minute video call with our Talent Acquisition Manager, Sadie . She will tell you more about Circuit and ask questions to help get to know you too.

Technical interview with the hiring team: You’ll have a 60-minute video call with the hiring manager, Gonza . To help him get to know you, he will ask about your work history, technical achievements, and your take on engineering culture.

Take-home assignment: At this stage, we will send you a brief for a technical test project so we can see how you approach a challenge. It should take you around 8 hours, and we’ll pay you for your time.

Meet the CEO: You’ll have a 30-minute final video call with our Co-Founder and CEO, Jack. This is an informal chat and a chance for both sides to ensure there’s a great fit. It is also an opportunity for you to get a real feel for the company, our culture, and vision—straight from the person who built it.

Offer! We invite you to join our team.

If you need us to make any adjustments to our interview process, or if there is any way I can make you more comfortable for our first call, please let me know. Sadie
