About the role

Key responsibilities & impact

Design solutions, produce architectures and write RFCs for platform, reliability and infrastructure initiatives which have impact across Engineering and beyond
Maintain your hands-on credibility by helping teams ship scalable, reliable and cost-effective services
Partner with Product and Engineering Directors on planning by scoping and sizing large new platform initiatives that span multiple teams
Work with other Principal Engineers to create and update the architectural vision that will deliver on Beamery's strategy
Engage with other Principal Engineers in setting and advocating company-wide standards for operational excellence, observability, reliability and incident response
Take a whole-company view of major incidents, identifying recurring themes and turning them into company-level investments
Own and evolve the platform and infrastructure tech radar, making data-backed cases for the adoption and deprecation of technologies and services
Set the standard for operational ownership, supporting teams to own their services end-to-end
Coaching and mentoring Engineers all the way up to Staff level from teams across the organisation
Collaborate on customer solutions with non-technical stakeholders including Sales, Customer Success and our high profile, Fortune 500 customers
Stay connected to production through on-call, and use that vantage point to raise the bar for incident response, observability and reliability across the whole engineering organisation

Requirements

What you’ll need

A proven track record of designing and delivering scalable, reliable cloud-based infrastructure and platform services
Extensive experience running and supporting services in production environments, including on-call leadership and incident command at scale
Previous experience as an individual contributor in an Engineering leadership position (Staff+, Principal, Architect, etc.)
Deep expertise managing Kubernetes production clusters at scale — cluster lifecycle and upgrades, resource optimization (autoscaling, quotas), security (RBAC, Network Policies), high availability and troubleshooting complex networking or scheduling issues
Expertise with Infrastructure as Code (IaC), particularly Terraform, and modern GitOps practices
Strong software engineering foundations with the ability to build and maintain production-grade tooling. Experience with Go would be preferable. NodeJS is a plus
A strong understanding of observability, SLOs, alerting and cost management for large-scale systems
Operational experience with our key infrastructure components: Kafka, MongoDB, PostgreSQL, Elasticsearch, and Istio
Familiarity with LLMOps is a plus; helping shape how we operate LLM-powered systems at scale (model gateways and routing with LiteLLM, experiment and model tracking with MLflow) would be a welcome bonus
A FinOps mindset; you drive cost-awareness as an engineering discipline across teams, balancing spend against reliability and performance, and turn infrastructure cost into a metric teams own rather than a surprise on the bill
People leadership in the form of mentorship and coaching
Ability to collaborate with non-technical colleagues to convert ambiguously defined problems into well-understood requirements and pragmatic solutions
