Responsibilities
- Own the architecture and evolution of core infrastructure as traffic, data volume, and workload complexity grow.
- Build capacity models, run load and stress tests, diagnose bottlenecks, and improve throughput, latency, reliability, and cost efficiency.
- Design resilient AWS account, IAM, networking, multi-AZ, and multi-region architectures.
- Build and operate Kubernetes platforms, including cluster lifecycle, workload isolation, autoscaling, upgrades, and deployment reliability.
- Scale and optimize Aurora RDS for MySQL and Postgres, including queries, indexes, replication, failover, migrations, and recovery.
- Implement reliability patterns such as service-level objectives, error budgets, failure isolation, backpressure, load shedding, and safe retries.
- Participate in on-call rotations and lead technical recovery during serious incidents and outages.
- Design, test, and document disaster recovery, backup, restore, and failover mechanisms.
- Build infrastructure-as-code, deployment automation, operational tooling, observability, and safe infrastructure migrations.
- Improve cloud cost efficiency and build AI-assisted tooling for incident investigation, runbooks, anomaly analysis, and toil reduction.
- Write architecture proposals, evaluate tradeoffs through prototypes and benchmarks, and document shared infrastructure behavior and failure modes.
Requirements
- Bachelor’s degree in Computer Science or a similar technical field is required.
- 12+ years of experience across infrastructure, platform, site reliability, software development, or related engineering disciplines.
- Deep production expertise with AWS, including compute, IAM, multi-account architectures, VPC design, and private connectivity.
- Deep production expertise with Kubernetes, including cluster lifecycle, scheduling, resource management, autoscaling, networking, and troubleshooting; EKS is strongly preferred.
- Deep expertise with RDS/Aurora using MySQL and/or Postgres, including performance, indexing, replication, high availability, failover, backup, and recovery.
- Demonstrated delivery of infrastructure scaling improvements with measurable gains in capacity, latency, reliability, or cost efficiency.
- Strong coding and automation skills with Golang, Python, or similar languages, plus Terraform or equivalent infrastructure-as-code experience.
- Strong systems fundamentals in Linux, networking, DNS, TLS, storage, concurrency, and distributed-system failure modes.
- Experience operating 24/7 high-availability platforms, responding to incidents, and implementing postmortem remediation.
- Experience with disaster recovery, observability, load testing, capacity planning, and safe CI/CD practices.
- Active use of AI tooling in engineering or operations with the ability to verify generated code, recommendations, and operational actions.
- Ability to solve ambiguous system-wide technical problems and collaborate across engineering disciplines.
- Preferred qualifications include fintech, payments, or banking experience; multi-region architectures; chaos and failure testing; Prometheus, Grafana, Loki, or Tempo; internal platform and self-service tooling; and AI-assisted incident investigation or operational automation.
Benefits
- Full-time remote position.
- Monthly gross compensation range of $12,500-$20,800 based on location and experience.
- Opportunity to work on infrastructure supporting fintech and payment workloads.
- Collaborative culture with engineering, data, and other technically diverse teams.
