Principal Software Development Engineer — Platform & Infrastructure

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/Cloud Formation/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 optimisation practices (rightsizing, reserved/spot strategies, architecture changes, cost monitoring and showback)
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 containerisation and Kubernetes at scale (EKS or comparable)
Practical experience with infrastructure as code (Terraform, Cloud Formation) 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, Git Hub Actions, Git Lab 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 and observability stacks (Prometheus, Grafana, Datadog, Open Telemetry, Jaeger)
Proven experience with AWS cost optimisation 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 and compliance for cloud environments, secrets management, and policy‑as‑code
Experience migrating monoliths to cloud‑native architectures
