Site Reliability Engineer - Human Engineering

The Human Engineering Software team builds tools used across Apple for user studies, research participant management, health data collection, and privacy-preserving analytics. Our infrastructure spans Django backends, Kubernetes clusters (self-hosted and AWS), PostgreSQL, Redis, Kafka, Elasticsearch and a growing set of internal service integrations.

This role is engineering-forward SRE. You'll spend as much time designing systems as operating them. You'll work closely with our full-stack engineers to improve how services communicate, how we observe production behavior, and how we ship changes safely. You'll have a seat at the architecture table - we want you proposing solutions, not just implementing them.

We're looking for a Site Reliability Engineer who thinks like a systems engineer first and an operator second. You won't just keep things running - you'll shape how our platform evolves. Our team operates 50+ services across Kubernetes and AWS, handles sensitive health and research data, and is ramping up many architectural shifts: new service-to-service auth patterns, event-driven pipelines, and a move from on-prem to cloud-native infrastructure. We need someone who gets excited about that kind of work, can reason about distributed systems at the design level, and is a strong enough communicator to bring the rest of the team along., * BS in Computer Science, Engineering, or equivalent practical experience, with 5+ years of experience in distributed systems

• Deep experience with Kubernetes in production - cluster operations, networking, storage, troubleshooting
• Strong proficiency designing and operating services in AWS (EC2, EKS, RDS, S3, IAM, VPC)
• Hands-on infrastructure-as-code experience (Terraform, Helm, or equivalent)
• Proficiency in at least one backend language (Python, Go, or similar) - you can write production services, not just scripts
• Experience with CI/CD pipeline design and GitOps workflows
• Strong understanding of networking fundamentals: DNS, load balancing, TLS, firewall rules, service discovery
• Excellent communication skills. You can explain a complex system to a room of engineers who didn't build it
• Experience building internal automation or self-service tooling (Slack bots, CLI tools, workflow orchestration) that reduced manual operational work, * BS in Computer Science, Engineering, or equivalent practical experience, with 7+ years of experience in distributed systems
• Experience with event-driven architectures (Kafka, RabbitMQ, or similar messaging systems)
• Experience with service mesh or API gateway patterns (Istio, Envoy, Kong, or similar)
• Familiarity with Django/Python web applications and their operational characteristics (Celery, Gunicorn, PostgreSQL)
• Experience with observability tooling beyond basic monitoring: distributed tracing, SLO frameworks, structured logging
• Background working with sensitive data (health data, PII) and associated compliance requirements
• Experience leading incident response and building on-call culture
• Contributions to internal or open-source infrastructure tooling
