What we're looking for

We're looking for a Backend Software Engineer who likes working in a close-knit team. You'd mainly be working on our web application, so solid Ruby on Rails experience is a must.

The ideal candidate will be someone who can hit the ground running and is keen to play an integral part as we scale up the software engineering team within the company.

You should be able to build clean, secure and efficient code based on specifications and in compliance with coding standards. Ideally you'll also have an interest in cyber security.

Further requirements:

  • Proven experience as a Software Engineer building web applications using Ruby on Rails
  • Knowledge of Docker and Kubernetes
  • Ability and willingness to learn new languages and technologies
  • Close familiarity with Agile development methodologies, software engineering tools, software design, test-driven development and release processes
  • BSc degree in Computer Science or Engineering or equivalent industry-level experience

What’s in it for you

Intruder is a dynamic and well-funded startup operating in a very fast growing market (even during the current economic downturn). You'll join the company at just the right time, we've established a product-market fit and things are now really taking off!

This is an intermediate role and we're offering a competitive salary in the range of £55,000 - £70,000, depending on your existing experience and skill set. In addition, we will add share options that allow you to significantly benefit financially as we increase the value of the company.

Our development team is remote-first and located around the globe, and we’ll consider applications from within 2 hours of the GMT timezone. We're going through a period of significant growth, so our top priority is to ensure we keep our fun but professional working environment. We do have a base in London, and employees based there are welcome to work from our WeWork office in Shoreditch.

Application process

We've designed our application process to be as fair as possible. We don't do 'gotcha' questions or whiteboard exercises -- we want to learn what you're like to work with, not whether you've memorized quicksort!

  1. Introductory call with one of our engineers. This is a chance to get to know each other: we'll tell you about Intruder, and you can tell us a bit about yourself.
  2. We'll send you a take-home coding task. We'll be available to answer any questions you might have throughout.
  3. A video interview with 3-4 Intruder engineers where you talk us through your solution to the coding task. We might ask about your design decisions and tradeoffs, and maybe some more general questions.
