About Infinity

We are building the next generation of call intelligence and AI-driven insight platforms. Over the next three years, our focus is on evolving from a strong analytics foundation into an outcome-driven, API-first platform that embeds intelligence directly into customer workflows.

This is an opportunity to join us at a pivotal stage. You’ll help shape both how we build and what we build, working on systems that process high-volume, high-value data and increasingly leverage AI and automation to deliver measurable customer and business outcomes.

We value pragmatic engineering, clear thinking, and continuous learning. Our teams are small, autonomous, and outcome-focused, with a strong emphasis on quality, ownership, and collaboration.

We are entering our next growth phase - investing in AI-powered platform scalability, operational excellence and maturity, and cost-efficient growth to support our long-term strategy and enterprise ambitions.

The Role

As Head of DevOps, you will lead Infinity’s cloud, infrastructure, and platform reliability functions, ensuring that our systems are secure, scalable, observable, and continuously deployable. You will shape and execute the DevOps and Platform Engineering strategy, enabling high-velocity software delivery with best-in-class automation, observability, and DORA-driven performance metrics. Reporting to the CTO, you will manage a small but high-impact team of two DevOps/SRE Engineers, working closely with the other teams within the Product & Engineering (P&E) organisation to build the next-generation operational foundation for Infinity’s AI-driven SaaS platform.
