Senior Platform Engineer - Data Infrastructure

Company Description
Nexthink is the leader in digital employee experience management software. The company provides IT leaders with unprecedented insight allowing them to see, diagnose and fix issues at scale impacting employees anywhere, with any application or network, before employees notice the issue. As the first solution to allow IT to progress from reactive problem solving to proactive optimization, Nexthink enables its more than 1,500 customers to provide better digital experiences to more than 25+ million employees. Dual headquartered in Lausanne, Switzerland and Boston, Massachusetts, Nexthink has 9 offices worldwide.
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, and the Cloud Infrastructure group is the reason the whole thing stays up. All 50+ of our product engineering teams build on the foundations we run. The company has grown from on-prem to cloud and is now bringing more intelligence into the platform, so there is plenty of genuinely interesting work to do on the layer underneath it all.
Job Description
About the team
The Data Infrastructure team looks after the data backbone: how those events are taken in, processed, stored, and served, and everything that keeps them reliable, fast, and affordable to run. When a piece of data infrastructure becomes important enough that several teams depend on it, looking after it properly becomes our job.
Today that estate covers Kafka (Amazon MSK), ClickHouse (on Amazon EKS), Amazon Aurora, and MongoDB (Atlas) across several AWS regions. We are now adding search, vector, and in-memory stores (OpenSearch, Redis, ElastiCache) to support new product work. You would join a small group of experienced engineers who own their areas from the first design through to running them in production. We like DevOps and CI/CD, we automate the things worth automating, and above all we care about doing the work well.
Why this role matters
Almost everything our customers rely on sits on top of this layer. When a product team promises customers high availability for what they have built, that promise only holds if the Kafka, the databases, and the streaming underneath hold too. Your work allows Nexthink to move quickly and trust the ground they are standing on.
What you will do

• Design and improve our data infrastructure alongside the Architecture, Product Engineering, and Security teams, following cloud-native good practice.
• Build the tooling and automation that provisions and scales it, with a real focus on resilience and elasticity, and make it self-service (Crossplane) so product teams can build on it with confidence.
• Bring in and run new kinds of data store (search, vector, in-memory and caching) to the same standard as everything else we look after.
• Spend time with the product and feature teams, understand what they actually need, and bring that back to shape the platform.
• Plan for the bad days: disaster recovery and cross-region replication, with clear RPO and RTO targets.
• Keep an eye on availability, performance, and observability (Datadog) so you spot trouble before it turns into an incident.
• Handle incidents from start to finish: spot them, work out what happened, fix them to SLA, and write the post-mortem. You will share the on-call rotation with the rest of the team.

How we work
A few things that are true about this team and, we think, make it a good place to build:

• It is a small team with real ownership. You look after your own areas and make the call on what is best for the platform, rather than working through a queue of tickets someone else has written.
• We do not work in a silo. We spend a lot of time with the teams who build on us, including a good deal of design work together, so the platform grows around what people genuinely need.
• The scale keeps it interesting. We run across several regions on modern AWS tooling, which is a good deal more involved, and more rewarding, than a single-region setup.
• We are improving something that already works. The platform is live and doing its job. Our task is to take it from good to really good, so the problems are about pushing things further rather than wiring up the basics.
• Like everyone here we use AI tools day to day, and we are slowly moving the more repetitive operational work onto automation. We do it carefully, because infrastructure is not somewhere to be careless.

Qualifications
What you will bring
The essentials

• A solid cloud infrastructure background and good software-engineering habits, usually around 5+ years as a Software, DevOps, Platform, or Site Reliability Engineer. A Computer Science degree or the equivalent in real experience.
• Hands-on AWS across several regions, with infrastructure as code (Terraform or OpenTofu) and pipelines (GitHub Actions, GitOps / Flux). Our platform runs entirely on AWS.
• Kubernetes and Amazon EKS on Linux with containers (Docker): running, upgrading, and patching workloads in production.
• Confidence in Go and/or Python.
• Clear thinking and good communication, and the organisation to keep several things moving at once, all in English.

Nice to have

• Experience running distributed and streaming systems, especially Apache Kafka (AWS MSK).
• Running database clusters (Amazon Aurora, ClickHouse, MongoDB and the like): configuration, backup and restore, and day-to-day production operations, including operators for data systems on EKS.
• Building self-service internal developer platforms, ideally with Crossplane or something similar.
• Familiarity with search or vector databases (OpenSearch, Elasticsearch) and in-memory or caching stores (Redis, Amazon ElastiCache).
• Some exposure to disaster recovery and cross-region replication (RPO / RTO).
