[Who we are looking for]

The Ministry of Finance is transforming government procurement through the Whole of Government Procurement initiative. GeBIZ X will revolutionise the procurement experience for WOG public officers and external suppliers.

We are seeking a Senior Platform Infrastructure Engineer to oversee the Enterprise Infrastructure of the GeBIZ X Product. You will demonstrate technical leadership in infrastructure engineering, designing, building, and operating the infrastructure ecosystem that comprises Ivalua SaaS as the Base Solution, seamlessly integrated with Extended Solutions including COTS and SaaS applications, connecting to government agency systems and the Singapore Government Tech Stack (SGTS). This orchestration layer, hosted on AWS Government Commercial Cloud (GCC) using API Gateway and SFTP protocols, serves as the critical integration hub.

You will be expected to navigate technical complexity across GovTech, Government agencies and technology partners, ensuring the interoperability of GeBIZ X and the wider network of systems whilst maintaining resilience, security, scalability, and compliance with government standards.

Core Values

Decision-making

• When making important decisions, we identify overarching goals, weigh up our options, identify impact, and clearly communicate and manage the risks and trade-offs of our decision.

Ownership

• In addition to technical responsibilities, this means having opinions on what is being done and having ideas on what should be done next. Building something that you believe in is the best way to build something good.

Continuous Learning

• Working on new ideas often means not fully understanding what you are working on. Taking time to learn new architectures, frameworks, technologies, and even languages is not just encouraged but essential.

  Systems thinking for scalable ecosystem design spanning multiple environments, analytical leadership translating business problems to infrastructure solutions, effective stakeholder management across project teams and vendors, and self-driven ownership committed to leveraging technology for public good.

Technical Leadership Expectations

• Engineer Resilient Platform Infrastructure at Scale 
  Engineer resilient systems through deep understanding of infrastructure engineering and user behaviour. Tackle cross-cutting technical issues elegantly, establish high monitoring standards, and engineer systems with observability in mind to evaluate behaviour at scale.

• Lead Complex Platform Infrastructure Transformations 
  Apply systems thinking to improve efficiency, repeatability, and scale. Evolve infrastructure practices based on feedback and failure mode observations. Lead design, implementation, and launch of platform infrastructure services across multiple teams, navigating technical and organisational complexity with sound judgement.
