Company Description:
Nexthink helps IT teams delight people at work. Behind that promise sits a platform that takes in trillions of events a day from more than 15 million devices, running on a cell-based architecture that spans AWS regions around the world. The Core Infrastructure team builds and runs the AWS foundation that the whole of engineering depends on. The company has grown from on-prem to cloud and is now making room for new kinds of work, including AI and agent workloads, so there is plenty of genuinely interesting work to do on the layer underneath it all.
- Why this role matters

Almost everything the rest of engineering does sits on top of this foundation. Every product team, whether they are working on the AI features or the everyday ones, depends on the networking, the clusters, and the platform you look after being there and behaving. You are not building the features yourself, but you will be the reason the people who do can move quickly and trust the ground they are standing on.

What you will do
- Design, deploy, and run AWS infrastructure from end to end:



from the edge and networking through to the multi-account cell architecture and the EKS platform.
- Move between operational work, automation, requests from other engineering teams, and greenfield design, depending on what the platform needs that week.
- Automate as much as sensibly possible: the infrastructure-as-code and GitOps that provision, upgrade, and keep the whole estate consistent and free of drift.
- Work closely with the product and feature teams, turning what they need into self-service capabilities and helping them stay autonomous.
- Keep the platform reliable, secure, and cost-effective: upgrades, autoscaling, observability, and security hardening and compliance (FedRAMP, FIPS). You will share the on-call rotation with the rest of the team.
- Help the architecture grow: design new capabilities and take the platform to the next level of scale, resilience, and new kinds of workload
