Senior Site Reliability Engineer, IaaS

Algolia is the retrieval intelligence layer that turns intent into trusted, decision-grade outcomes. Powering more than 1.7 trillion queries a year for over 18,000 customers with millisecond latency and 99.999% reliability, we are the recognized leader for Search and Product Discovery by top industry analyst firms. The Algolia platform turns a company's products, content, and business rules into data that humans, applications and AI agents can act upon. The result is trusted customer experiences with stronger conversions for measurable business impact. The team The Infrastructure as a Service team is at the center of one of Algolia’s most consequential engineering transformations. For years, Algolia has operated a production fleet of approximately 4,000 bare-metal servers to deliver the reliability, low latency, and scalability that our customers expect. We are now building the foundations of a unified cloud and Kubernetes platform designed to support Algolia’s growth for years to come. This is not a lift-and-shift project. It is an opportunity to rethink how Algolia provisions, secures, operates, observes, upgrades, and scales production infrastructure and to build it as a platform that engineers can safely consume, rather than a queue of manual requests. The opportunity As a Senior Site Reliability Engineer in IaaS, you will help shape the next generation of Algolia’s production infrastructure. You will lead major parts of the Cloud Baseline and the reliable lifecycle capabilities that enable teams to operate and migrate workloads safely on a cloud-native platform. You will work across cloud foundations, Kubernetes, platform engineering, automation, reliability, and large-scale production operations. This role is for an engineer who enjoys solving infrastructure problems where the answer must work not once, but hundreds or thousands of times: creating repeatable cloud environments, enabling a growing fleet of production clusters, reducing manual operations, and maintaining the reliability and cost efficiency our customers expect throughout the transition. YOU WILL: Lead the design and evolution of Cloud Baseline capabilities across cloud providers, including identity and access, networking, account structure, security, auditability, tagging, inventory, and cost visibility. Design and automate cloud infrastructure foundations that enable a growing fleet of production Kubernetes clusters. Lead complex infrastructure initiatives, such as cloud-environment standardisation, cluster lifecycle automation, upgrade strategies, or infrastructure-drift reduction. Ensure cloud and Kubernetes foundations, lifecycle operations, and operational guardrails are reliable and scalable enough to support large-scale workload migration without compromising customer experience. Treat the platform as a product: define clear interfaces, reusable modules, self-service workflows, documentation, and reliable operational standards for the engineers who consume it. Build automated guardrails for security, compliance, reliability, and safe change management, allowing teams to move faster without weakening production protections. Improve platform efficiency through capacity planning, rightsizing, autoscaling, resource governance, and clear cost visibility. Use automation and AI-assisted engineering tools where appropriate to improve fleet-scale analysis, infrastructure documentation, and safe, repeatable operational changes. Mentor engineers, share knowledge, and raise the quality of infrastructure design and operations across the team. Collaborate with Infrastructure, Security, FinOps, and engineering teams to align technical decisions and deliver high-impact platform capabilities. Participate in the on-call rotation and lead the resolution of complex production issues. YOU MIGHT BE A FIT IF YOU HAVE: Strong hands-on production expertise with AWS or GCP. Deep practical Kubernetes knowledge, including its cloud infrastructure dependencies and operational challenges. The ability to design, build, and operate reliable cloud infrastructure in production. Strong infrastructure-as-code and automation skills, ideally Terraform and Python, Go, or equivalent. Solid knowledge of Linux, networking, distributed systems, and production operations. A platform mindset: you design for the engineers who consume what you build, balancing velocity, correctness, security, and reliability. Awareness of cloud cost drivers and the ability to treat cost as an engineering constraint. A track record of leading complex technical initiatives and delivering durable solutions across teams. Comfort adopting AI-assisted engineering tools, with strong judgement for critical production systems. Excellent spoken and written English skills. NICE TO HAVE: Familiarity with more than one public cloud provider. Knowledge of GitOps or policy-as-code tooling, such as Argo CD, Helm, OPA, or Kyverno. Exposure to cloud migration, platform engineering, FinOps, or large-scale infrastructure transformation.
