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.

WHAT YOU’LL DO

Design, implement, and tune distributed systems that handle

high-throughput B2B traffic .

Harden our AWS stack with IaC (e.g. Terraform)

Instrument everything—logs, traces, metrics, and AI-powered anomaly detection.

Champion security, cost optimization, and disaster-recovery strategies.

Jump into the weeds when something breaks, fix it fast, then automate it away.

WHAT YOU’LL BRING

Must-Haves

5+ years owning production systems at meaningful scale (sub-second latency, “four-nines” targets).

Mastery of SRE fundamentals : SLO / SLI design, error budgets, incident playbooks.

Deep hands-on with Linux, networking, containers / K8s, and at least one major cloud (AWS / GCP / Azure).

Proven track record automating infra with Terraform, Helm, or similar IaC tooling.

Fluency in at least one systems / scripting language (Go, Python, Rust, etc.).

Experience operating complex data pipelines (Prefect, Airflow, Temporal) or real-time streaming systems.

History of mentoring engineers and embedding reliability culture across teams.

Pragmatic decision-maker—balances uptime, velocity, and cost for startup reality.

Curiosity for AI-augmented ops (LLM chat-ops, anomaly detection, self-healing).

Nice-to-Haves

Managed GPU clusters and ML inference workloads.

Operated data lakes / lakehouses at scale (Iceberg, Delta, etc.).

Meaningful open-source contributions in SRE, DevOps, or data-infra projects.
