Senior Site Reliability Engineer (SRE) - Cassandra & AWS - Talent Connection

About the Position

We are seeking a Senior Site Reliability Engineer (SRE) with expertise in Cassandra and AWS to join our LATAM team, focusing on platform reliability and scalability. Real ownership from day one, not check-ins and micromanagement. That's what the Senior Site Reliability Engineer (SRE) role at Nortal looks like.

Responsibilities

• Design, build, and operate highly available, fault-tolerant distributed systems and caching platforms.
• Evaluate the existing architecture and identify opportunities to scale the platform 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.

Requirements

• 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.
• Hands-on AWS experience and familiarity with cloud-native architecture.
• Experience designing and implementing automated CI/CD pipelines and deployment strategies for highly available systems.
• Experience with infrastructure/configuration/secrets as code and a strong preference for automated, repeatable processes.
• Strong understanding of observability, monitoring, alerting, performance metrics, and production troubleshooting.
• Experience with performance testing, capacity planning, and identifying system bottlenecks.
• Strong programming or scripting experience for automation and tooling; Java/Spring Boot experience strongly preferred.
• Ability to work independently, take ownership of ambiguous technical problems, and move work forward with limited direction.
• Ability to provide technical leadership and establish practical engineering standards and guardrails within a small team.
• Advanced English Level is required for this role, as you will work with US clients. Effective communication in English is essential to deliver the best solutions to our clients and expand your horizons.

Nice to Have

• Experience with GraphQL and API gateway architectures.
• Kubernetes and containerized application experience.
• GitLab CI/CD experience.
• Terraform or other infrastructure-as-code tools.
• Prometheus, Grafana, Datadog, or similar observability platforms.
• Kafka, Amazon MSK, or other event-streaming technologies.
• Experience designing active-active or multi-region architectures.
• Experience with enterprise customer-data platforms or high-volume caching systems.

We Offer

• Competitive USD salary.
• Full remote work, with coworking spaces across LATAM if you want to meet the team in person.
• Paid time off under your country's rules, at full salary.
• National holidays.
• Sick leave, no stress attached.
• A yearly refundable credit. Spend it on anything related to your health and well-being.
• A day off for your birthday.
