Head of DevOps

Location: Flexible:
Reigate or Manchester area

Job type: Full time

Working Pattern: Hybrid | 4.5 day working week (Half day Fridays)

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.

As Head of Dev Ops, 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 Dev Ops 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 Dev Ops/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.

This should include the 4 to 5 key Infinity behaviours needed for the role eg:
To succeed in Infinity and this role you need to be able to work smart, hard and with a positive energy. You work at pace always looking for ways to improve things and with an eye on the results. You are a creative thinker who dares to do things differently. Being a team player is essential. In infinity that means being open, honest, consistent and fair and contributing to a sense of purpose and positive team morale.

• Lead the management and optimisation of serverless and event‑driven architectures, leveraging AWS Lambda, API Gateway, and related services.
• Oversee cloud cost management, performance tuning, and disaster recovery planning.

• Oversee the design and continuous improvement of CI/CD pipelines (Git Hub Actions) to ensure rapid, low‑risk deployments.
• Embed automated testing, code quality gates, and policy‑as‑code enforcement.
• Implement progressive delivery techniques such as blue/green and canary deployments to reduce risk.
• Integrate Dev Sec Ops  practices, automating security scanning, dependency management, and compliance checks.

• Establish and maintain platform‑wide observability through dashboards, alerts, SLOs, SLIs, and SLAs.
• Use modern observability stacks (e.g. Prometheus, Grafana, Datadog, ELK) for proactive monitoring and root cause analysis.
• Lead post‑incident reviews and ensure continuous improvement through robust RCA and feedback loops.
• Own and report on service reliability metrics (availability,…
