Lead Enterprise-Grade Infrastructure and Reliability for a Growing Multi-Product SaaS Platform
Overview
As the first dedicated Site Reliability Engineer (SRE), you will play a pivotal role in supporting a growing portfolio of AI-powered SaaS products that help organisations manage compliance, fraud, and corporate misconduct risks.
You will be responsible for designing and scaling shared infrastructure, improving platform reliability, establishing observability and operational excellence, and strengthening security across multiple products. This is not a traditional infrastructure operations role. Instead, you will help create the systems, processes, and engineering foundations that enable sustainable business growth and enterprise-grade service delivery.

- Develop and improve CI/CD pipelines and deployment processes
- Enhance system reliability, availability, performance, and security

About the Opportunity
Given the highly sensitive nature of the data being processed, including internal communications and whistleblowing-related information, the organisation operates to security and operational standards that exceed those of many traditional SaaS businesses.
As the product ecosystem expands, there is a growing need for scalable, repeatable infrastructure and development practices. To support this next phase of growth, the company is seeking its first dedicated SRE to lead both platform reliability and developer productivity initiatives.
