About Oxford Nanopore Technologies
Oxford Nanopore Technologies is a UK‑headquartered company with global operations and customers in more than 125 countries. Our goal is to bring the widest benefits to society through enabling the analysis of anything, by anyone, anywhere. We have developed a new generation of nanopore‑based sensing technology for faster, information‑rich, accessible, and affordable molecular analysis. The first application is DNA/RNA sequencing, and we are expanding into analysing proteins and other molecules. Our technology is used to understand and characterise biology and diseases such as cancer, plants, animals, bacteria, viruses, and whole environments, thereby improving life on Earth and beyond.
The Role

* Identify vulnerabilities through threat modelling, exploratory testing, static analysis, dynamic analysis, misuse scenarios, penetration testing, and security tooling.
* Design and maintain security‑focused test cases based on requirements, architecture, and risk.
* Produce clear, high‑quality vulnerability and defect reports, and work with developers and the compliance function to validate fixes and prevent regressions.

You Might Be a Good Fit If You Have
* Experience in software security testing, application security, or software testing with a strong security focus.
* Experience with NIST 800-53 or similar standards.
* Hands‑on experience testing desktop or platform software on Linux and/or macOS (Windows experience is beneficial).
* Understanding of common security vulnerability types and risk‑based testing approaches.
* Experience using security testing tools such as intercepting proxies, vulnerability scanners, or dependency analysis tools.
* Familiarity with at least one programming language such as Python, JavaScript, Ruby, or similar; ability to write scripts or small tools to support testing.
