(EG0069) Senior Site Reliability Engineer (SRE) - Cassandra & AWS - Talent Connection
Nortal, Latin America +1
The role
As a Senior Site Reliability Engineer, I help modernize and scale production platforms, most recently a customer-data caching platform that serves 20–25+ consuming applications at about 3,000 requests per second. I work across SRE, DevOps, engineering and architecture to improve resiliency, automation, observability, deployment practices and overall platform reliability. I work independently, set technical direction and do well in small engineering teams.
What you will do
- Design, build and operate highly available, fault-tolerant distributed systems and caching platforms.
- Evaluate the existing architecture and identify opportunities to scale the platform toward 6x current traffic while maintaining performance and resiliency.
- Improve caching strategies, including TTLs, refresh patterns, cache placement, performance and downstream dependency management.
- Help evolve the platform toward active-active resiliency and validate failure, recovery and capacity scenarios.
- Design and implement automated CI/CD pipelines, including rolling, blue/green or canary deployment strategies, automated checks and quality gates.
- Establish infrastructure, configuration, secrets and application deployment practices using an everything-as-code approach.
- Build performance and load-testing capabilities and establish meaningful performance gates for releases.
- Develop monitoring, alerting and observability for cache latency, throughput, availability, errors and other key reliability indicators.
- Define and improve SLIs, SLOs, error budgets and operational KPIs where appropriate.
- Automate operational tasks and reduce manual intervention through scripting, tooling and infrastructure automation.
- Troubleshoot production issues, perform root-cause analysis and drive reliability improvements through blameless post-incident reviews.
- Provide technical guidance and establish engineering guardrails for SRE and development teams.
- Collaborate with Java/Spring Boot engineers, architects, client FTEs and other technical teams to deliver platform improvements.
What you need
- Bachelor's Degree in Computer Science, Engineering, or a related field.
- 5+ years of experience working in Site Reliability Engineering, DevOps, platform engineering or a similar production infrastructure role.
- Apache Cassandra experience, including data modeling, replication, consistency, tuning and multi-datacenter deployments.
- Experience operating and scaling distributed systems in production environments.
- Strong understanding of caching architectures, performance optimization and high-availability systems.
