Job Description
As a Senior Full Stack Engineer at CSA Cyber, you will design, build and maintain new user-facing features across our proprietary, cloud-hosted platform, including the Unified Portal that gives our customers visibility of the cyber security services we deliver. Reporting to the Head of Software Engineering and working within an agile team, you will take features from concept through to production across the full stack, in an AWS-hosted environment.
You will be a senior contributor: setting a high bar for code quality and security, helping shape technical direction, and mentoring other developers as we scale a platform that sits at the heart of CSA’s managed services. Critically, you will be an advocate for AI engineering: someone who genuinely embraces AI tooling and knows how to embed it effectively across the software development lifecycle (SDLC) to raise the team’s pace and quality.
