Backend Engineer - Platform Security

Reference: u09kwx2dcxw29pqn09uf

We are seeking a Backend Engineer to join a platform security team responsible for building reliable, scalable services that protect applications, infrastructure, and customer data. In this role, you will design, develop, and maintain backend systems that support identity, access management, authentication, authorisation, secrets, policy enforcement, and security automation. You will work closely with software engineers, infrastructure specialists, security professionals, and product stakeholders to deliver secure solutions that are practical, resilient, and easy to operate.

Your responsibilities will include designing service architectures and APIs, writing high-quality production code, improving system performance and reliability, and contributing to technical decisions across the platform. You will help identify and address security risks, participate in threat modelling and design reviews, and support the implementation of secure development practices. The role also involves building monitoring and alerting, investigating incidents, strengthening operational processes, and contributing to post-incident improvements. You will be expected to review code, document systems clearly, contribute to automated testing and deployment pipelines, and promote engineering standards that support confidentiality, integrity, and availability.

We are looking for experience developing backend services in languages such as Go, Java, Python, or a similar language, together with a strong understanding of software design, distributed systems, databases, networking, and cloud environments. Knowledge of security principles, including authentication protocols, authorisation models, cryptography, vulnerability management, and secure coding, is highly valued. Experience with containers, infrastructure as code, observability tools, and continuous delivery is beneficial. You should be comfortable working through ambiguous problems, communicating clearly with both technical and non-technical colleagues, and balancing delivery with long-term maintainability. A curious, collaborative mindset and a commitment to improving security through thoughtful engineering are essential.
