Senior Site Reliability Engineer

• 🧱 Platform-wide impact: You set how reliability, observability and operational readiness work across the whole platform, and every team shipping on it feels the difference.

• 🤖 Agentic systems in production: You’ll set the guardrails, identity and blast-radius controls for agents operating against real systems and data, and work out what could go wrong before it does.

• 🛠 Golden paths: You’ll make the platform legible to agents as well as people, through golden paths, MCP servers, skills and documentation that both can actually use.

• 🚀 Startup pace with scaleup reach: Five years in, we’re working with over 1,000 brands across AU, NZ, USA and the UK, with plenty of scaling still ahead.
• Build and maintain the cloud infrastructure and paved paths teams ship on, so resilience, security and scalability come as defaults rather than as decisions each team makes on its own

• Give teams observability they can self-serve: monitoring, alerting, logging and tracing, plus automation for provisioning, deployments and the operational work nobody should be doing by hand

• Make incidents easier to handle: the tooling, runbooks and practice that let whoever is closest to the problem debug it quickly, and post-incident reviews that turn into actual changes

• Set the identity and least-privilege model for non-human actors, including agents, CI and MCP servers, so teams can give agents real access without real risk

• Document infrastructure designs and operational procedures in a form both people and agents can act on, including machine-readable runbooks

• Set the standard for what is safe to ship, and make it easy to meet through guardrails and checks in the pipeline rather than through gatekeeping

• Give teams visibility and controls over cloud and inference spend, so the cost of what they run is something they can see and act on

• Coach engineers in reliability practices, and work with Engineering and Product to balance feature delivery against platform needs
• You’ve run incident command on real production incidents, and you’ve owned a platform through a meaningful scaling step

• Deep infrastructure skills: Infrastructure as Code (Terraform, Terragrunt, CDK), containers (ECS), cloud platforms (AWS preferred, or GCP/Azure), CI/CD, and scripting in Python, TypeScript or Bash.

• Strong on observability: Datadog or similar, distributed tracing and structured logging, and a solid grasp of incident management methodology.

• Security-minded: Networking and cloud architecture fundamentals, plus an understanding of the security model for agentic systems, including credential handling, least privilege and prompt injection.

• Works with agents: You use coding agents in your own work (Claude Code or equivalent) and have a point of view on where they help and where they don’t.

• Product-oriented: You navigate technical complexity with business outcomes in mind, and can clearly communicate system health, risks and trade-offs to technical and non-technical people.

• Kind: This is a collaborative role, so we ultimately want a great, supportive team player.

• Bonus points if you’re passionate about marketing, design, and building exceptional user experiences.

Some of the tools we use: AWS, ECS, Terraform and Terragrunt, GitHub Actions, Datadog, Claude Code, Linear, Notion, Postgres, DynamoDB and Snowflake.
