Unlock Your Potential as a Network Security Specialist

We are on a mission to create a secure and reliable network infrastructure.

Our team is responsible for designing and implementing systems that protect our network from invalid traffic and fraud. As a key member of this team, you will contribute to the development of cutting-edge solutions that ensure the authenticity and quality of data powering our machine learning systems.

This role is perfect for entry-level/early career professionals who want to grow as an engineer while contributing to meaningful work. You will learn from experienced colleagues and gain hands-on exposure to challenges such as fraud detection, invalid traffic mitigation, and incident response.

No prior experience in network security or fraud prevention is required. You will be supported as you build your skills while working on projects like:

  • Identifying unusual traffic patterns using user-agent analysis and IP reputation scoring, and utilising AI tech to protect the network
  • Helping design systems that filter out invalid/fraudulent traffic and protect the quality of data signals
  • Supporting incident response processes to contain and mitigate threats
  • Exploring new approaches such as Proof-of-Work checks and closed-loop event validation
  • Gaining hands on experience coding in modern backend programming languages, working on AWS microservices in a distributed-systems architecture.
What You Will Do:
  • Contribute to the design and development of systems that help detect and reduce invalid traffic and fraud
  • Work closely with senior engineers to implement foundational protections, including IP reputation, rate limiting, and anomaly detection
  • Support the creation of runbooks and tools that enable quick and clear responses to threats
  • Collaborate with engineers, product managers, and data scientists, learning from experienced mentors while contributing your own ideas
  • Build your skills in AI/ML integration, large-scale data pipelines, and network security practices while contributing to projects that create measurable value
Why Join Our Team?
  • Impact Across the Business: This role isn't confined to one team - you will get exposure, and build subject matter expertise, in many areas of the business.
  • Innovate with AI: Be a pioneer in applying AI and automation internally at a company that truly values innovation.
  • Endless Learning: Every project is a new puzzle to solve across different domains, so you'll constantly expand your expertise in operations, analytics, product, and more.
  • Empowered Culture: Join a team of owners in a culture that encourages you to act boldly and learn from every experiment.
  • Great Environment & Benefits: Work with smart, down-to-earth colleagues in a vibrant, inclusive workplace. We offer transparent career progression, continuous development opportunities, equity ownership, and perks to support your growth and well-being.
