Senior software engineer

Entity: Technology Job Family Group: IT&S Group Job Description: Job Title: Senior software engineer About the Role We’re hiring a Senior software engineer to help build Yalla, our Internal Developer Platform (IDP). Yalla enables teams across our organisation to provision infrastructure, deploy code, and operate services in a secure and standardised way — all via self-service. This is a hands-on engineering role working across the full stack: you'll be building on top of the core platform (using Kubernetes, ArgoCD, and Crossplane), as well as any supporting tooling such as the developer portal, backend services, and observability that bring Yalla to life for product teams. You'll work closely with internal users to understand developer needs, simplify workflows, and turn complex platform capabilities into intuitive developer experiences (DevEx). What You’ll Do Design, build, and operate features across the full Yalla stack — including:Platform infrastructure (Kubernetes, GitOps, provisioning workflows) Backend APIs and services (e.g., service catalog, deployment orchestration) Frontend portal (React-based developer UI) Tooling (Observability, Artifact Storage, Azure DevOps) Build reusable templates and automation for provisioning environments, services, and CI/CD pipelines. Integrate with tools like ArgoCD, Crossplane, and language-native build systems (Go, .NET, Java, Node.js, Python). Contribute to platform contracts and APIs used by product teams. Collaborate with engineers across the company to define platform standards and improve developer experience. Improve reliability, observability, and security across all layers of the platform. Mentor and coach engineers, providing guidance on coding practices, design reviews, and operational standards. Design with observability in mind, ensuring platform systems are reliable, and transparent. Own the full lifecycle of feature development from proposal & planning to implementation & deployment. What We’re Looking For Must-Have: Proven experience building and deploying full-stack applications (ideally React + Go/ .NET/ Java/ Node.js/ Python). Fluent in multiple high-level languages, adaptable to new ones as needed. Strong understanding of cloud-native architecture (AWS/Azure). Strong knowledge of Kubernetes internals (scheduling, networking, controllers, orchestration). Familiarity with GitOps workflows and infrastructure-as-code (e.g., Terraform, Crossplane, Helm). Experience with CI/CD tooling (Azure DevOps, GitHub Actions, etc.). Ability to work across front-end and back-end boundaries, turning platform concepts into intuitive UX. Comfortable navigating a mixed-language environment. Nice-to-Have: Experience building internal platforms, IDPs, or self-service developer tooling. Experience of working in a monorepo. Knowledge of service communication patterns (REST, GraphQL, gRPC, messaging). Experience in secure, regulated environments (e.g., SoX, audit requirements).
