Mobile Security Engineer
Every day, Barclays’ mobile apps support hundreds of thousands of customers with important financial transactions, and it is critical that these transactions are secure. Our Android and iOS mobile apps use multiple layers of cryptography and encryption to protect customers and their data.
To support this, we are hiring a Mobile Security Engineer who will play a key role in building and maintaining our mobile security containers, controls, and protocols. This role is suitable for applicants who have a strong engineering foundation and a genuine interest in learning mobile security, rather than deep prior experience in the domain. This is an excellent opportunity to grow your technical capability in mobile security within a supportive engineering environment.
We recognise that mobile security is a specialist area. As such, we are looking for someone who is curious, motivated, and keen to develop niche skills, supported by on-the-job learning and mentoring.
Successful candidates will have:
- A solid foundation in at least one programming language such as Java, Kotlin, Swift, Objective‑C, C#, or Node.js.
- A good understanding of the software development lifecycle, including source control, build, test, and release activities.
- Some hands‑on experience or exposure to build pipelines using tools such as Jenkins or GitLab Pipelines.
The following skills or interests would be beneficial, but are not essential:
- An interest in software cryptography concepts and how they are applied in internet‑facing mobile applications.
- Awareness of build and release controls, including versioning, dependency management, and promoting artefacts across environments.
- A well‑organised approach with strong attention to detail.
- The ability to manage multiple work requests and adapt priorities as needed.
You may be assessed on the key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen, strategic thinking and digital and technology, as well as job-specific technical skills.
