We're working with a fast-scaling SaaS company operating in the cyber security education space. With over 4 million users globally and continued rapid growth, they're on a mission to make learning cyber security accessible and engaging through a gamified training platform.
As part of their expansion, they're now looking to hire a Full-Stack Growth Engineer to join a small, cross-functional team focused on product growth experiments and A/B testing of new product features and functionaility. This role is ideal for someone who thrives on delivering measurable user impact and is comfortable working in fast, iterative build-measure-learn cycles.

The Opportunity:

  • Design and implement scalable, secure, and reliable software systems across the full stack
  • Monitor system performance and experiment outcomes to guide future development
  • Participate in Agile development practices, code reviews, and technical planning
  • Contribute to a culture of experimentation, quality, and rapid iteration


What We're Looking For:

  • 3-5 years of hands-on experience as a full-stack engineer (preferably within SaaS or product-led environments)
  • Proven experience working in a software growth team or directly on product growth experiments
  • Strong skills across the MERN stack (Node.js, React, Express, MongoDB)
  • Familiarity with CI/CD workflows and cloud-based environments (AWS preferred)
  • Understanding of scalable system design and front-end performance best practices
  • Comfortable working in small teams and contributing across the development lifecycle
  • Strong communication skills and the ability to work autonomously in a remote-first environment
  • Interest in cyber security or educational platforms is a bonus


Why Join:

  • Work at the intersection of education and cybersecurity in a product that truly impacts users
  • Be part of a fast-moving team where your contributions directly influence growth and engagement
  • Flexible, remote-first culture and strong technical leadership
  • Opportunity to grow your skills in experimentation-led product development


If you're excited by the challenge of helping scale a product used by millions and you have hands-on experience working on growth-focused software teams we'd love to hear from you.
