Co-Development Business Unit is looking for Platform Engineer

This is a fixed term contract role. The engagement is 12 months

Internal Code: A26023

If you are:

• Engineers that are excited by building internal platforms similar to Vercel or Railway.
• Builders who enjoy turning complex infrastructure into simple developer workflows.
• Engineers who want to work across backend platform services, GitOps workflows, and frontend developer experience.

this is the role for you.

What will you do?

Platform & Abstraction Design (Primary Focus)

• Design and build developer-facing abstractions over AWS and Kubernetes that hide infrastructure complexity.
• Build platform services, APIs, CLIs, controllers, or operators that enable simple deployment workflows similar to modern PaaS platforms.
• Define opinionated defaults for networking, security, scaling, and reliability, while allowing controlled extensibility.
• Treat platform components as long-lived products with clear interfaces, documentation, and adoption metrics.

Software Engineering

Write production-grade code primarily in:

• Go or Python for platform services, automation, and Kubernetes integrations.
• TypeScript for contributing to the internal developer portal and related APIs.

Apply strong software engineering fundamentals:

• API and interface design
• Versioning and backward compatibility
• Error handling and failure modes
• Testing and maintainability

Design code with the expectation that other engineers and tenant teams build on top of it.

Internal Developer Portal (Custom-Built)

• Contribute features and improvements to a custom internal developer portal built with TypeScript and NextJS.
• Design workflows, forms, and APIs that enable self-service provisioning, deployment, and observability.
• Ensure the portal reflects platform standards, guardrails, and golden paths.
• Collaborate closely with backend platform components to deliver a cohesive developer experience.

CI/CD, GitOps & Deployment Workflows

• Design and maintain GitOps-based deployment workflows using ArgoCD.
• Build reusable CI/CD abstractions using GitLab CI/CD for build, test, and promotion workflows.
• Integrate CI pipelines with ArgoCD for safe, auditable, and repeatable deployments.
• Support deployment strategies such as canary and blue-green deployments to minimise downtime.
• Reduce deployment friction for tenants by standardising workflows and removing the need for deep CI/CD or Kubernetes expertise.

Infrastructure as Code (IaC)

• Design and maintain reusable Terraform modules that encode platform standards and guardrails.
• Abstract AWS and Kubernetes primitives behind stable, versioned interfaces.
• Ensure infrastructure changes are auditable, repeatable, and safe for multi-tenant usage.
• Databases and Data Protection
• Design platform-level patterns for database provisioning and operations.
• Support and validate backup and restore strategies, including automated backups, snapshot management, and recovery testing.
• Work with tenants to ensure data durability, recoverability, and minimal downtime during incidents.

Observability and Monitoring

• Build platform-level observability capabilities using Elastic Cloud for logs, traces, dashboards, and alerting.
• Integrate Prometheus for metrics scraping and collection, with metrics surfaced via Elastic.
• Apply the Four Golden Signals (latency, traffic, errors, saturation) as a core observability principle.
• Provide standard dashboards, alerts, and SLOs that tenants inherit by default.

Production Support and Incident Management

• Participate in incident response for platform components.
• Design platform features that improve debuggability, enable safe rollbacks, and reduce MTTR.
• Drive post-incident improvements by evolving platform design rather than relying on manual processes.

Performance, Optimisation, and Reliability

• Design platform components for scalability, performance, and cost efficiency.
• Identify and address bottlenecks at the platform layer.
• Continuously improve reliability through automation, better defaults, and guardrails.
• Tenant Engagement, Developer Experience & Knowledge Sharing
• Engage tenant teams as a technical advisor on platform usage and best practices.
• Produce clear documentation, diagrams, runbooks, and examples that improve onboarding and adoption.
• Gather feedback from tenants and iterate on platform capabilities based on real usage.

Continuous Learning

• Stay current with developments in AWS, Kubernetes, GitOps, and the cloud-native ecosystem.
• Evaluate new tools and patterns relevant to internal developer platforms and PaaS-style workflows.
• Share learnings within the team and contribute to continuous improvement
