Junior Developer


Company Description: Fast-growing AI startup building e-commerce tools


Job Description:

Join a lean, experienced engineering team building AI-powered tools that streamline e-commerce operations for businesses and charities. As an early-career developer, you will contribute to production features, solve complex technical problems, and improve existing systems. This role focuses on thoughtful engineering and practical solutions rather than following industry hype.


Location: London, UK


Why this role is remarkable:

  • Work directly alongside senior engineers who prioritize clean, maintainable code and pragmatic technical decisions.
  • Gain hands-on experience with production-grade AI applications that solve real-world commercial problems for active customers.
  • Join a small, low-ego team where your individual contributions have a visible impact on the product.


What you will do:

  • Contribute to the development of new product features and the improvement of existing system architectures.
  • Write well-structured, maintainable code while learning how production-level software is built and scaled.
  • Troubleshoot technical challenges and collaborate with the team to find efficient, long-term engineering solutions.


The ideal candidate:

  • Possesses a solid understanding of programming fundamentals and proficiency in at least one modern language.
  • Demonstrates a history of self-directed learning through side projects, GitHub activity, or technical tinkering.
  • Displays strong logical thinking and the ability to communicate technical concepts clearly and effectively.


Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

Step 6. If not, Jack will find you excellent alternatives. All for free.


We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
