Tracksuit exists to help marketers prove their brand building is working. We give teams the data they need to make smarter decisions, convince stakeholders, defend budgets, and track their progress.

The brand tracking industry is dominated by 100-page reports, static data and big price-tags. We're doing things differently by being built for the modern marketer: always-on, accessible, and approachable.

We're now tracking more than 1,000 brands across 25 countries globally. With offices in Auckland, Sydney, London and New York City, we're scaling fast with a brilliant team of collaborative and ambitious humans. Our culture is defined by "high care, high performance". We strive to be the best and look after each other while we do it.

Are you our next Senior Site Reliability Engineer?

We’re on the lookout for a Senior Site Reliability Engineer to join Tracksuit, based in our Auckland office.

You’ll set how reliability, observability and security work at Tracksuit, from the AWS infrastructure underneath the platform through to the agents, MCP servers and model-backed features running on top. Teams build and run their own services, and the SRE team makes it straightforward for them to do that well, through the golden paths, guardrails, tooling and defaults that make the reliable way the easy way, plus the support to lean on when something does break.

Why this role is special

• 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.

What you'll do

• 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

That's the role, so who are you?

• 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.
