Senior Platform Engineer (Observability)

You’ll be joining Stora at an exciting time - on the ground floor of our new Platform Engineering team. With a slant towards observability and infrastructure, you’ll have the opportunity to shape how the team operates and contribute to the technical direction.

From day one, you’ll take ownership of designing and operating the systems that give us deep insight into the health, performance, and reliability of our platform. Your work will span monitoring, logging, alerting, tracing, and infrastructure as code — equipping our developers and operators with the visibility and tooling they need to deliver a world-class product.

Your Responsibilities

• Lead the design, rollout, and management of observability systems (Grafana, Prometheus, Loki).

• Lead the migration away from our old AppSignal setup.

• Define and implement monitoring, application logging, audit logging, and alerting strategies across AWS.

• Build Terraform modules to provision observability and core infrastructure.

• Work closely with product and platform teams to ensure services are well-instrumented and reliable.

• Help establish and measure SLIs/SLOs to guide operational excellence.

• Proactively monitor, investigate, and resolve production issues, driving preventative improvements.

Our Technology Stack

We’re pragmatic and pick tools that balance speed and sustainability. Key elements relevant to this role include:

• Observability: Managed Grafana, Managed Prometheus, Loki, OpenTelemetry

• Infrastructure: Moving from Heroku to AWS (EC2, RDS, CloudFront, S3, IAM, Managed Grafana, Managed Prometheus, etc.)

• Infrastructure as Code: Terraform

• Application stack (for context): Rails 7.1, PostgreSQL/TimescaleDB, Redis, Sidekiq

• CI/CD & Ops: GitHub Actions, Docker, Kamal, Heroku (migration to AWS in progress)

What We’re Looking For

Proven experience in:

• Designing and operating production-grade observability stacks (Grafana, Prometheus, Loki).

• Building and managing AWS infrastructure.

• Writing and maintaining Terraform modules for infrastructure and monitoring.

• Defining and managing key metrics, alerting, dashboards, and log pipelines.

• Troubleshooting complex production systems with a focus on reliability.

• Communicating technical concepts clearly across teams.

Bonus points for:

• Experience with OpenTelemetry

• Familiarity with Kamal

• Background in incident response and on-call practices.

• Interest in security, compliance, and cost optimisation in observability.

Important: This is a hybrid role based in Northern Ireland.

• Competitive annual salary – starting from £65k for 5-day week (pro-rated for 4-day week).

• Health & wellness – Private health insurance for you and your family.
