Site Reliability Engineer Jobs in Draper, UT (NOW HIRING)

At MX, reliability is a product. Our infrastructure powers financial applications used by millions of people and processes billions of transactions for major financial institutions, and customers feel every second of downtime.

We're building a new observability function that runs the way we run incident response: the system does the heavy lifting, and people handle judgment, customers, and the exceptions. As a Senior Observability Engineer, you build and operate an observability control plane. You scaffold baselines, score coverage, and turn every real incident into the detection the platform should have caught. This is a multiplier role: you raise the bar for every team through standards and automation instead of building each team's dashboards by hand.

We call it the shepherd model. You shepherd Datadog and partner with our product engineering teams so they observe the right signals for their products. Service owners get real signal instead of noise, and leadership gets coverage and health as a program metric.

This role shares the team pager. Observability and incident response run one on-call roster. You take shifts with the rest of the team and act as Incident Commander when an incident needs one. It is core to the role, not an afterthought.

Engineering at MX runs hybrid infrastructure (AWS and bare metal) with services in Ruby, Go, and Java, messaging over NATS and RabbitMQ, and data on PostgreSQL and Redis. Datadog is our observability platform and incident.io is our incident response platform.

• Build and operate an observability control plane: automate baseline monitors, dashboards, and tagging standards through the Datadog API and Terraform.

• After significant incidents, produce detection and dashboard gap packs grounded in Datadog and MX investigation patterns, with queries ready to apply.

• Define what "good" looks like for a Ruby, Go, or Java service on Datadog (tags, golden signals, alert quality, dashboard contracts), then audit services against that standard and accept or reject readiness.

• Validate, don't own. Service owners keep their alerts and dashboards; you confirm they are complete and correct, then move on. Escalate to engineering managers when coverage fails or an owner is missing.

• Own the monthly observability and service-catalog health report: departed owners, stale dashboards, services with no monitors, SLO gaps, and coverage trends.

• Run maturity assessments (baseline through SLO, launch-ready, self-serve) and track them over time.

• Tune alerting toward zero false SEV1/2 pages and actionable SEV3/4 alerts, and coach teams on Datadog cost and cardinality.

• Build self-serve onboarding so new services get baseline observability on day one, without a multi-week embed.

• Share the team pager. Rotate on the shared IR & Observability on-call, triage and investigate live incidents with Datadog and MX investigation patterns, and take Incident Commander or supporting technical roles as the incident needs.

• After incidents, close the detection loop (gap packs, new monitors, dashboards) so the pager gets quieter over time.

• Run high-value launch and production-readiness reviews as a checkpoint, not a permanent staffing model.

• BS in Computer Science or equivalent experience

• 5+ years running production observability, SRE, or DevOps

• 5+ years automation-first engineering in Python, Bash, Go, and/or Terraform, plus Kubernetes proficiency

• AI- and workflow-literate. You've used or built scripted and AI-assisted workflows to scale reviews, audits, and docs

• Distributed-systems debugging across microservices: latency, connection pools, queues, and cascading failure on Kubernetes and bare metal, with NATS, RabbitMQ, Postgres, and Redis

• Shared on-call, Incident Commander-capable

• Fintech experience with MX-like architectures

• Datadog preferred; strong Grafana/Prometheus, Splunk, or New Relic experience counts if you can ramp on Datadog fast

• Google SRE practices: toil elimination, incident management, automation for self-healing

• Cross-functional influence without authority. You've improved teams that don't report to you

• Governance and reporting: you can produce a monthly health and compliance report leadership reads (orphans, stale entries, gaps, trends)

• OpenTelemetry instrumentation

• Incident response platforms (incident.io, PagerDuty, OpsGenie); prior formal Incident Commander experience

• Golang and Ruby on Rails (the MX stack)
