Principal Software Engineer (DevSecOps)

Reference: zfdy8yur89qnjjd2du1k

We are seeking a Principal Software Engineer (DevSecOps) to provide technical leadership across the design, development, deployment, and operation of secure, scalable software platforms. You will help shape engineering strategy, establish modern DevSecOps practices, and guide teams in delivering reliable products at pace. The role requires a hands-on leader who can work across architecture, software engineering, cloud infrastructure, automation, and cybersecurity while influencing technical decisions across the wider organisation.

Your responsibilities will include defining and evolving CI/CD strategies, embedding security controls throughout the software development lifecycle, and developing automated pipelines for build, test, release, compliance, and infrastructure provisioning. You will design and improve cloud-native platforms, champion infrastructure as code, strengthen observability and operational resilience, and promote engineering standards for quality, performance, and maintainability. You will also identify technical risks, lead architectural reviews, support incident resolution, and ensure that systems meet appropriate security, regulatory, and availability requirements. A key part of the role will be mentoring engineers, facilitating knowledge sharing, and building alignment between software, platform, security, and delivery teams.

Applicants should have substantial experience in software engineering and DevSecOps, with a strong background in designing and operating distributed systems and cloud environments. You will be confident working with modern programming languages, containers, orchestration platforms, version control, automated testing, monitoring, and CI/CD tooling. Experience with public cloud services, infrastructure-as-code frameworks, secure software supply chains, vulnerability management, identity and access management, and policy-as-code is highly desirable. Strong understanding of software architecture, Agile delivery, reliability engineering, and secure coding practices is expected. Excellent communication and stakeholder-management skills are essential, along with the ability to translate complex technical issues into clear recommendations and to lead through influence in a changing environment.
