Site Reliability Engineer

Primer helps B2B products break out of the B2C-centric marketing box. Our platform turns consumer ad channels, data streams, and emerging AI workflows into measurable growth engines for go-to-market teams. We ingest billions of rows from first- and third-party sources, map them to rich company context, and surface hyper-targeted audiences and real-time performance alerts—all without vendor lock-in.

That only works if the lights stay on , queries stay fast , and incidents stay rare . That’s where you come in.

As our first dedicated Site Reliability Engineer , you’ll be the force multiplier who designs, builds, and operates the infrastructure that powers everything : petabyte-scale data pipelines, LLM-backed services, and the APIs our customers (and engineers!) rely on every day. You’ll pair hard-won ops experience with a mentor’s mindset—levelling up the whole team while keeping us four steps ahead of failure.

YOUR MISSION

Own reliability from design to customer.

• Define and uphold SLOs / SLIs, manage error budgets, and lead blameless post-mortems.
• Automate toil out of existence—CI / CD, infra-as-code, capacity planning, and chaos testing.
• Drive incident response end-to-end : detection, mitigation, root-cause analysis, and long-term fixes.
• Scale multi-cloud data pipelines (Prefect, ClickHouse, Iceberg) and GPU / LLM workloads.
• Teach best practices, review designs, and coach engineers so reliability becomes a team sport.
