What we're looking for

We're looking for a Senior Software Engineer who likes working in a close-knit team and enjoys all aspects of the dev process.

The ideal candidate will be someone who can play an integral part in developing and scaling our technology so it can meet the needs of a global SaaS platform. The role also involves taking on a leadership position within the software engineering team, which will include line management, hiring of new engineers and continuously aiming to improve existing processes.

Ideally you'll have a keen interest in cyber security, and also enjoy the challenge of presenting complex concepts in an 'easy to understand' way.

You should be able to build clean, secure and efficient code based on specifications and in compliance with coding standards.

Further requirements:

  • Proven experience as a Senior Software Engineer or similar role building web applications using Ruby and/or Python. If you've only worked with one of these languages we'd expect a willingness (and ability) to pick up the other as both are extensively used at Intruder.

  • Knowledge of Vue.js or equivalent Javascript framework

  • Knowledge of docker and Kubernetes
  • Experience of building and scaling SaaS apps
  • Experience as team lead and providing mentoring to other developers
  • 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

  • Significant experience analysing and improving the efficiency, scalability, and stability of various system resources
  • 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, we've just doubled the size of the team and things are now really taking off!

This is a senior role and we're offering a competitive salary in the range of £70,000 - £90,000, 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 base is London, but a large part of our team is located around the globe. Although London-based employees are welcome to work from our WeWork office in Shoreditch (near Old Street), the development team will continue to have a 'remote-first' culture. We're going through a period of significant growth right now but our top priority is to ensure we keep our fun but professional working environment. We'll consider remote applications for this role as long as you're within 2 hours of the GMT timezone.

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.
