About the Role
We are building the next-generation foundational platform with a focus on developer experience, reshaping how the entire organization builds, ships, and operates software. As a Software Engineering Manager, you will define golden paths, shape our developer portal, and enable a large engineering organization to move faster, safer, and with greater autonomy.
Responsibilities
- Line manage, mentor and grow a team of platform engineers and SREs.
- Build a high-performing, psychologically safe culture that values learning, accountability and continuous improvement.
- Define and execute the platform roadmap including compute, networking, storage, CI/CD and Kubernetes-based services.
- Balance technical debt, reliability work and new feature delivery.
- Own SLIs/SLOs for platform services, drive reliability programmes, and ensure teams meet agreed availability and performance targets.
- Champion end-to-end observability (metrics, tracing, logging), lead major incident responses, and run blameless post-incident reviews with actionable RCA and follow-through.
- Promote automation-first approaches for provisioning, deployments and runbook automation using IaC and CI/CD best practice.
- Work closely with InfoSec to embed secure configurations, secrets management and compliance controls into the platform lifecycle.
Requirements
- 3 years + leading platform, SRE or infrastructure teams in a cloud-native environment (typically 3+ years in management plus strong hands-on experience).
- Hands-on experience operating cloud services at scale with a solid understanding of SLIs/SLOs, error budgets and incident lifecycle.
- Deep experience with AWS services (compute, networking, storage and managed services) and cloud operational patterns.
- Practical experience with Terraform, CloudFormation or equivalent.
- Strong knowledge of Kubernetes, Helm and related ecosystem tools.
- Experience implementing and operating metrics, tracing and logging stacks such as Prometheus, Grafana, ELK/OpenSearch or Jaeger.
- Familiarity with pipeline tooling (GitHub Actions, GitLab CI, Jenkins) and automation frameworks to enable reliable delivery.
- Comfortable writing and reviewing code or scripts (Python, Go, Bash) to automate tasks and build platform tooling.
