Job description

The client is a Singapore-based data consultancy seeking a hands-on Senior Infrastructure Engineer to deploy and operate the ingestion and distributed-storage layer of a large-scale on-premise data platform.

This is an initial six-month contract, with the potential for extension or conversion to a permanent position based on business requirements and individual performance.

Key Responsibilities

·Design and build production-grade platform services, APIs and reusable Python libraries.

·Develop authentication and authorisation integrations using OAuth 2.0, OpenID Connect and role-based access control.

·Implement secure identity propagation across distributed platform components and services.

·Build and maintain Model Context Protocol endpoints and related service integrations.

·Containerise services using Docker and deploy and operate them on Kubernetes.

·Integrate platform services with data, infrastructure, observability and security components.

·Write automated tests, technical documentation and maintainable deployment procedures.

·Troubleshoot service reliability, security, integration and production-performance issues.

·Work directly with technical stakeholders and contribute as a senior individual contributor.

Requirements

·Minimum six years of hands-on software, backend or platform-engineering experience.

·Advanced Python experience, including building custom libraries, packages, SDKs or reusable platform components.

·Proven experience developing production APIs, backend services or microservices.

·Strong hands-on experience with OAuth 2.0, OpenID Connect, JWT, RBAC and identity propagation.

·Production experience with both Docker and Kubernetes is mandatory.

·Strong software-engineering practices covering testing, version control, CI/CD, security and documentation.

·Experience deploying services in on-premise or hybrid environments.

·Ability to work independently, solve ambiguous technical problems and communicate effectively with client stakeholders.

·Willingness to accept a six-to-twelve-month contract and attend client locations when required.

Preferred Experience

·Experience building or integrating Model Context Protocol endpoints.

·Exposure to platform observability, policy enforcement and secure service-to-service communication.

·Experience delivering platform products within regulated or security-sensitive environments.

This is a product-engineering role focused on Python platform services. It is not primarily an ETL, business‑intelligence, analytics or data‑pipeline position.
