The role

This company is building a privacy-first perception engine, turning existing cameras and sensors into real-time operational intelligence without facial recognition or hardware swaps. They're tackling a petabyte-scale data infrastructure challenge: ingesting and processing real-time feeds from thousands of customer sites. This isn't a typical SaaS reliability surface; think financial market data aggregation, but for the physical world.

You'll be the founding engineer for a new Resilience function, owning the availability, performance, and scalability of this unique platform. This is a greenfield opportunity to apply a software engineering mindset to operations, designing systems from scratch. It's not about running a ticket queue; it's about building the infrastructure that makes petabyte-scale real-time data reliable.

The work

• Design, build, and operate a centralized, petabyte-scale data ingestion pipeline, solving novel reliability challenges akin to financial market data.
• Architect and implement production Kubernetes clusters and GitOps workflows from scratch, ensuring high availability and scalability.
• Automate manual operations work across deployment, monitoring, and incident response, embedding a software engineering approach into infrastructure.
• Define and manage SLOs/SLIs for critical systems, leading root cause analyses that result in tangible preventative changes.
• Establish and champion documentation standards (runbooks, post-mortems, system docs) as a core engineering deliverable.
  
  

What You Bring

• You've built at least one production Kubernetes cluster from scratch, not just operated an existing one.
• You're fluent with GitOps workflows in production and have strong opinions on their optimal setup and operation.
• You write code to automate operations work across deployment, monitoring, and incident response.
• You've defined and managed SLOs/SLIs for production systems and led RCAs that resulted in preventative changes.
• You are eligible to work in the UK and ideally based in London.
