Site Reliability Engineer

Why you:

Customer‑facing SRE role designing, operating, and supporting reliable, observable, and cost‑effective platforms across Linux, Kubernetes, and public cloud. You’ll manage workstreams, automate with IaC, improve SLOs/SLIs and alert hygiene, and support peers.

Data Platforms expectation: bring depth in one area and the responsibility/willingness to ramp on the others in 60–90 days:

Elasticsearch/OpenSearch

Redis (OSS/Enterprise; ElastiCache/Memorystore/Azure Cache)

Kafka–Hadoop–Spark (incl. Confluent/MSK/Event Hubs, Cloudera/CDP/Dataproc/EMR)

What you will be doing:

• Improve reliability, availability, and visibility for customer platforms; plan/execute documented maintenance; drive remediation/automation.
• Provide remote support for Linux-based infrastructure across data center and cloud environments.
• Manage the full OS lifecycle, including installation, deployment (Kickstart, VMs, containers, bare metal), patching, and upgrades.
• Design and implement automation for infrastructure deployment, configuration, and operations using scripting (Bash, Pythian) and tools (Ansible).
• Implement and evolve SLIs/SLOs, error budgets, capacity plans, and reliability reviews; harden observability (metrics/logs/traces) and keep alerts actionable.
• Build and extend infrastructure as code (Terraform/CloudFormation), configuration management (Ansible/Puppet/Chef/Salt), and GitOps (Helm, Argo CD/Flux) pipelines.
• Collaborate with support/app/data teams; reduce toil via scripting (Bash/Python) and small tools.
• Data Platforms – pick one at depth, ramp on others:
• Elasticsearch/OpenSearch: cluster ops, shard/replica strategy, ILM/snapshots, performance/security, EFK integration.
• Redis: cluster/Sentinel ops, failover drills, parameter tuning (maxmemory, timeouts), cache observability (hit ratio/latency/evictions), persistence/DR (RDB/AOF, snapshots).
• Kafka–Hadoop–Spark: topic/ACL management, retention/partitioning, connector basics, rolling upgrades; pipeline observability (lag/throughput/error rates); routine automation.

• Facilitate technical discussions with customers; advise on platform roadmaps and architecture trade‑offs.
• Support and cross‑train teammates; uphold documentation quality and internal knowledge sharing.
• Participate in on‑call, escalations, and change reviews; proactively reduce toil via scripting/automation.

What we need from you:

Core

• Strong Linux administration/troubleshooting; Kubernetes fundamentals (workloads, networking, storage, upgrades, security, HA); one major cloud (GCP/AWS/Azure).
• IaC + config management experience; CI/CD/GitOps familiarity; scripting with Bash and/or Python.
• Consulting mindset: clear English (written/spoken), estimation, stakeholder communication, documentation quality.

Data Platforms (depth in one; ramp on others)

• Elasticsearch/OpenSearch (ops, tuning, ILM/snapshots, security/EFK), or
• Redis (OSS/managed operations; data structures, eviction policies, RDB/AOF persistence).
• Kafka–Hadoop–Spark (production exposure; Confluent/MSK/Strimzi; Dataproc/EMR/CDP familiarity), or

Nice to have

• Security/IAM basics, budget/capacity awareness; Prometheus/Grafana experience; diagramming/runbook excellence.

What you will receive:

• Love your career: Competitive total rewards package. Blog during work hours; take a day off and volunteer for your favorite charity.
• Love your work/life balance: Flexibly work remotely from your home, there’s no daily travel requirement to an office! All you need is a stable internet connection.
