The Opportunity:

Were looking for a Lead Platform Engineer to own the infrastructure and security foundation that Lotties engineering teams build on.

This is a broad high-ownership role. Youll be the person who keeps our cloud infrastructure running well starts to own our security posture and looks for ways to improve how our engineers experience the platform underneath them every day. Its not a narrow specialism - we want someone who is energised by the full scope not just one slice of it.

Lotties infrastructure is modern simple and intentional. Our services run on Kubernetes (EKS) deployed following GitOps practices with GitHub Actions and ArgoCD and monitored with OpenTelemetry-powered logs traces and metrics. Our cloud surface is split across AWS for compute and GCP for data (BigQuery) with infrastructure managed as code through Terraform. We prioritise pragmatism stability and solving real problems over technology for technologys sake and this key role owns the future direction of the platform observability security and infrastructure as a whole.

Youll join as the sole owner of this function which means real autonomy and real accountability. The work is consequential: Lottie is scaling fast our products carry serious responsibility for the families and care providers who rely on them and the platform needs to be in safe hands.

What youll be doing

• Own Lotties cloud infrastructure end-to-end - reliability performance cost observability and developer experience

• Champion an observability culture where engineers own what they ship - giving teams the dashboards alerting and tooling to genuinely run their own services not just deploy them

• Set the guardrails for how we use AI safely - establishing security best practices and ways of working that let teams move fast with AI tooling without creating risk

• Lead our information security accreditations including ISO 27001 and Cyber Essentials - treating them as a chance to genuinely strengthen our posture not a box-ticking exercise

• Take genuine ownership of our security posture: auditing where we are identifying gaps and making pragmatic improvements over time

• Work closely with engineering teams to understand what they need from the platform and build things that actually help them move faster

• Evaluate and improve our IT and vendor setup including potential managed service arrangements

• We want someone who ties every infrastructure decision back to what it unlocks for the business - not building for the sake of technical interest

We think youll be a great fit if

• Youre breadth-first: youd rather own a wide area well than be the deepest possible expert in one narrow slice

• You have solid experience in cloud infrastructure DevOps or platform engineering - hands-on with GCP AWS or both

• You know Kubernetes deeply - not just deploying to it but running it in production: scaling debugging upgrades and the operational realities that only come from owning clusters yourself

• You have real observability expertise - youve built monitoring alerting and tracing that engineers actually use and you know the difference between collecting metrics and creating insight

• Youre comfortable owning security even if its not your deepest expertise today - youre curious about it you know what good looks like and youre willing to learn

• You come from a startup or cloud-native environment and you understand the difference between building for scale and over-engineering

• You have good judgment about what problems are worth solving - youre not chasing technical perfection for its own sake

• You can work well with engineers across teams; you build platform that helps people not just infrastructure thats technically correct

Sound like you but not quite 100% Apply anyway were looking for judgment and potential not a perfect spec match.

This role isnt for you if

• Our mission to elevate later life care doesnt resonate with you.

• You want to go deep in one specialism and leave the rest to someone else

• Security feels like a different teams problem

• Youre most comfortable in a large structured engineering org rather than a fast-moving startup

• Youd rather build technically impressive things than pragmatically useful ones
