Full Description

Oxford Nanopore Technologies: Our goal is to bring the widest benefits to society through enabling the analysis of anything, by anyone, anywhere. The company has 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 the technology is in development for the analysis of other types of molecules including proteins. The technology is used to understand and characterise the biology of humans and diseases such as cancer, plants, animals, bacteria, viruses, and whole environments. With a thriving culture of ambition and strong innovation goals, Oxford Nanopore is a UK headquartered company with global operations and customers in more than 125 countries.

The role

• We are seeking an Application Security Test Engineer to join our Instrument Software Test team. In this role, you will help ensure the security and quality of ONT’s desktop and platform software, which runs across Linux, Windows, and macOS and plays a critical role in controlling sequencing instruments and processing complex scientific data.
• This is a hands-on role suited to someone with practical experience in software or application security testing who is keen to deepen their expertise in a technically challenging, real-world environment. You will work closely with developers, product owners, and fellow testers to identify security risks, validate mitigations, and continuously improve how we test for security across the software development lifecycle. In this role, you won’t be expected to define company-wide security policy, but you will be expected to independently drive security testing activities within your area, apply good security judgement, and continuously improve how we test for security issues.

Key responsibilities

• Perform application security testing of desktop applications, background services, and supporting tooling
• Test across Linux, Windows, and macOS, including installers, configuration, permissions, logging, secrets handling, and update mechanisms
• Identify vulnerabilities through exploratory testing, dynamic analysis, misuse scenarios, 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 to validate fixes and prevent regressions
