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.
