In this team you'll have a unique opportunity to have first-hand exposure to the strategy of the company in key security initiatives, especially in building scalable and secure-by-design systems and solutions.

It's working fast, at scale, and we're making a difference.

Responsibilities:
- Conduct vulnerability research of the native components of the most critical systems and products (mobile and desktop apps, cloud).
- Collaborate closely with other security and product teams to design defense-in-depth controls that limit attackers' ability and improve our security posture.
- Drive secure-by-default and automation initiatives to boost native components' security.
- Monitor and analyze emerging cyber threats, vulnerabilities, and exploits relevant to our infrastructure, technologies, and products.
- Bring insight into all aspects of modern security issues to our products and rapidly developing prototypes for mitigations.
- Support Red Team with vulnerability research and exploit development.

Qualifications
Minimum Qualifications
- Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or other relevant majors.
- 3+ years of experience in ethical hacking, vulnerability research, product security, exploit development, or being a member of a red team.
- First-hand experience in C/C++ reviews, fuzzing, reverse engineering, and binary exploitation.
- Advanced knowledge and understanding in at least one of the following disciplines: end-user device security, cloud computing, operating system internals and hardening, mobile and desktop app security, network security, applied cryptography.

How Many Cyber Security Tools Do You Need to Know to Get a Cyber Security Job?

If you are trying to build or move forward in a cyber security career, it can feel like the list of tools you are expected to know never ends. One job advert asks for SIEM platforms, another mentions penetration testing tools, another lists cloud security, threat intelligence platforms, endpoint detection, scripting languages and compliance frameworks. Scroll LinkedIn and it gets worse. Everyone seems to “know” dozens of tools, certifications and platforms. Here is the reality most cyber security hiring managers agree on: they are not hiring you because you know every tool. They are hiring you because you understand risk, can think like an attacker and a defender, follow process, communicate clearly and make good decisions under pressure. Tools matter — but only when they support those outcomes. So how many cyber security tools do you actually need to know to get a job? For most job seekers, the answer is far fewer than you think. This article explains what employers really expect, which tools are essential, which are role-specific and how to focus your learning so you look credible, not overwhelmed.

The Skills Gap in Cyber Security Jobs: What Universities Aren’t Teaching

Cyber security has become one of the most critical disciplines in the modern economy. From protecting financial systems and healthcare data to securing national infrastructure, cloud platforms and supply chains, cyber security professionals now sit at the frontline of digital trust. Demand for cyber security talent in the UK has surged. Job vacancies remain high, salaries continue to rise, and organisations across every sector report difficulty hiring skilled professionals. Yet despite this demand, many graduates struggle to break into cyber security roles and employers consistently report that candidates are not job-ready. The problem is not intelligence, ambition or academic effort. It is a persistent and widening skills gap between university education and real-world cyber security work. This article explores that gap in depth: what universities teach well, what they routinely miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build sustainable careers in cyber security.
