Software Engineer III - Cloud Platform

Why this role matters:

As a Software Engineer on the Cloud Platform team, you are a force multiplier for our engineering teams. You don't just manage infrastructure; you write the software that makes shipping code at Vonage fast, safe, and easy. Working within the technical direction set by the architecture and Staff Engineer teams, your mission is to build and ship robust, developer-friendly automation and tooling on our cloud-native foundations - ensuring our production APIs remain highly available, scalable, and cost-efficient, all while eliminating friction for the hundreds of developers who depend on the platform every day.

Your key responsibilities:

• Software-Driven Platform Engineering Write production-quality code primarily in Go to build internal tooling, workflows, and automation - from infrastructure provisioning to deployment management and service health. You treat the platform as a product and developers as your customers.
• Infrastructure Ownership Take ownership of provisioning, maintaining, and improving our cloud-native infrastructure using established IaC patterns. You execute reliably within the architectural blueprints set by the team, keeping environments stable and meeting high-availability requirements.
• Kubernetes Operations Act as a key technical resource for our large-scale Kubernetes clusters. Dive deep into the stack to troubleshoot complex networking or performance bottlenecks and implement software-level fixes.
• Automate Guardrails Implement automated security policies and best practices directly into the cluster using policy enforcement tools such as Kyverno, OPA/Gatekeeper, or equivalent. Ensure that as we scale, clusters stay compliant and healthy without slowing down development teams.
• Streamline Delivery Own the "path to production" by building and optimising GitHub Actions workflows and ArgoCD pipelines, enabling global teams to deploy code safely through GitOps.
• On-Call Participation Share in the team's on-call rotation to support production reliability. The current expectation is approximately one week of 24/7 on-call coverage per month, shared equitably across the team.
• AI-Augmented Engineering Embed AI-assisted engineering into daily practice to accelerate delivery and enhance outcomes. Proactively adopt emerging AI capabilities to improve workflows and share best practices with the team.

What you'll bring

Experience 5+ years of software engineering experience with a strong focus on cloud-native architecture, developer tooling, and platform engineering.

Coding Excellence Strong proficiency in Go (preferred) or Python - you can build production-grade tools, APIs, and custom Kubernetes controllers to automate complex logic, not just write scripts.

Kubernetes Knowledge Practical experience managing and troubleshooting production EKS or GKE clusters. You are comfortable "under the hood" of a cluster - networking, scheduling, resource management.

CI/CD & GitOps Hands-on experience with ArgoCD and GitHub Actions, specifically creating reusable workflows and custom actions.

Policy & Configuration Experience using Helm for packaging and Kyverno (or OPA) for policy enforcement.

Infrastructure as Code Strong practical experience with Terraform - writing custom modules, managing state, and structuring IaC for maintainability - with an interest in moving toward Kubernetes-native management approaches such as Crossplane.

Observability Experience using tools like Prometheus or Grafana to monitor system health and performance.

FinOps Mindset You care about right-sizing resources - avoiding over-provisioning and keeping cloud spend efficient.

The Troubleshooting Mindset You enjoy solving hard problems and can navigate complex distributed systems to find root causes.

How you'll benefit:

• Attractive Discretionary Time Off
• Private Medical Insurance with optional dependent coverage
• Educational Assistance Reimbursement Program
• Opportunities for reimbursement for conferences, trainings, and other personal development events
• Maternity and Paternity Leave
• Ask recruiter for country specific information
• Additional benefits and perks will be shared and discussed with you by the recruiter during the interview process
