We are hiring a hands-on Principal Software Development Engineer to lead the design, implementation and operational excellence of our cloud infrastructure and platform capabilities. This role emphasizes platform engineering: designing and delivering a scalable, reliable, secure, observable, and cost-efficient runtime platform (Kubernetes, containers, CI/CD, IaC, cloud services) used by multiple product teams. You will both set strategy and be embedded in the code and infrastructure to execute the roadmap end-to-end.

You will shape the foundational platform that powers customer-facing services across brands, increasing developer velocity, reducing operational risk, and optimizing cloud spend. This role is ideal for a leader who can design complex systems, implement solutions in production, and lead broad cross-team adoption.   What you will do: • Define the technical strategy, roadmap and standards for cloud infrastructure and platform capabilities (container runtime, orchestration, networking, CI/CD, observability, security, IaC) • Lead migration and platform adoption efforts (containerization, Kubernetes/EKS, runtime platform) and drive roadmap execution end-to-end • Be an active code and IaC contributor (Terraform/CloudFormation/Helm, platform services, automation) and perform design/code reviews • Design scalable, resilient, and secure infrastructure patterns for microservices, data stores, caching, and messaging • Build and improve CI/CD pipelines, release automation, testing strategies, and safe deployment practices • Drive SRE and observability practices: define SLIs/SLOs, monitoring, tracing, alerting, runbooks, incident response, and post-mortems • Lead capacity planning, performance tuning, and traffic engineering for high-scale workloads • Own and evangelize AWS cost optimization practices (rightsizing, reserved/spot strategies, architecture changes, cost monitoring and show back) • Define and enforce platform standards, security controls, environment tagging, and operational excellence practices across teams • Mentor and grow senior and mid-level engineers; identify high-potential talent and raise engineering standards • Collaborate closely with product, security, platform, and operations stakeholders to align technical solutions with business goals and compliance requirements

Minimum qualifications: • 10+ years professional software engineering experience with significant hands-on experience building and operating distributed cloud services • Strong, demonstrable experience building and running platforms on AWS (EKS, ECS, EC2, VPC, IAM, S3, RDS, ELB/ALB, Auto Scaling) • Deep hands-on experience with containerization and Kubernetes at scale (EKS or comparable) • Practical experience with infrastructure as code (Terraform, CloudFormation) and Helm charts • Proven record of contributing production code and platform automation (languages such as Go, Python, Java, or similar) • Experience designing for resilience, observability, security and operational automation • Familiarity with CI/CD tooling and developer workflows (Spinnaker, Jenkins, GitHub Actions, GitLab CI, or similar) • Demonstrated ability to lead cross-team technical initiatives and influence architectural decisions • Strong communication skills and experience mentoring engineers  

Preferred qualifications : • Prior platform engineering, SRE, or infrastructure leadership at scale • Experience with monitoring/observability stacks (Prometheus, Grafana, Datadog, OpenTelemetry, Jaeger) • Proven experience with AWS cost optimization strategies and tooling (Cost Explorer, Trusted Advisor, billing APIs) • Knowledge of service meshes (Istio, Linkerd, VPC Lattice), API gateways, and advanced networking patterns • Experience with security/compliance for cloud environments, secrets management, and policy-as-code • Experience migrating monoliths to cloud-native architectures
