Mobile security Engineer
We are seeking a Mobile Security Engineer to help protect mobile applications, devices, services, and supporting infrastructure throughout the development lifecycle. You will work closely with software engineers, architects, product teams, and security specialists to identify risks, design effective controls, and ensure security is built into mobile products from the outset. The role will involve assessing Android and iOS applications, reviewing source code and architecture, analysing application behaviour, and supporting the resolution of vulnerabilities.
Your responsibilities will include conducting mobile application security assessments, penetration tests, threat modelling exercises, and code reviews; developing security requirements and reusable guidance for mobile engineering teams; and helping to improve authentication, authorisation, encryption, secure storage, certificate validation, API communication, and protection against reverse engineering and tampering. You will investigate security incidents and suspicious activity affecting mobile platforms, contribute to vulnerability management, and clearly document findings, business impact, and recommended remediation. You may also create scripts, tools, and proof-of-concept demonstrations to support testing and automate recurring security checks within development and delivery pipelines.
The successful candidate will have practical experience in mobile application security and a strong understanding of Android and/or iOS security models, common mobile attack techniques, and standards such as OWASP MASVS and MASTG. Experience with tools for static and dynamic analysis, traffic inspection, debugging, instrumentation, and vulnerability testing is expected. You should be comfortable reading code in languages such as Kotlin, Java, Swift, or Objective-C, and have a working knowledge of secure software development, APIs, cryptography, CI/CD, and cloud-connected services. Relevant security certifications or demonstrable equivalent experience are welcome. Strong communication and analytical skills are essential, along with the ability to explain technical risks to both specialist and non-specialist audiences and to work collaboratively in a fast-moving environment.
