Application Security Engineer

Reference: r39uwk1ns3hpt3czxd3s

We are seeking an Application Security Engineer to help protect the software development lifecycle and strengthen security across a diverse range of applications, services and platforms. You will work closely with software engineers, architects, DevOps specialists and product teams to identify, assess and remediate security risks from design through to deployment. The role will involve embedding secure development practices, promoting security awareness and providing practical guidance that enables teams to deliver resilient, high-quality solutions.

Your responsibilities will include conducting threat modelling, secure code reviews and application security assessments, as well as supporting penetration testing and vulnerability management activities. You will help define and maintain security requirements, standards and controls, and contribute to the integration of security tooling into CI/CD pipelines. You will investigate reported vulnerabilities, prioritise findings according to risk and business impact, and work with engineering teams to agree and track effective remediation plans. You will also monitor emerging threats, assess their relevance to the technology estate and contribute to incident response where application-related security issues arise.

The successful candidate will have professional experience in application security, software development, security engineering or a closely related discipline, with a strong understanding of secure coding principles and common vulnerabilities such as those outlined by OWASP. Experience with threat modelling methodologies, code analysis tools, penetration testing techniques and cloud-based environments is highly desirable. You should be comfortable working with modern development practices, APIs, containers and infrastructure as code, and ideally have familiarity with programming or scripting languages such as Python, JavaScript, Java or C#. Strong communication and influencing skills are essential, as you will need to explain technical risks clearly to both technical and non-technical audiences. Relevant industry certifications or demonstrable equivalent experience would be advantageous.
