What does a chief technology officer do?
A chief technology officer (CTO) is the most senior technology leader in an organisation.
The CTO sets the technology direction, approves which technologies the business adopts, and reports to the chief executive officer (CEO) or the board.
In Singapore, the role sits in the executive team. Some firms give the CTO the duties of a chief information officer or chief information security officer too. The national occupation code groups the three roles together. In a startup, a CTO may still write code.
A CTO works with the CEO, finance, product, sales and legal teams. Inside technology, the CTO leads engineering managers, architects and heads of data or security. Outside the firm, the CTO deals with vendors, clients and regulators.
What the work involves
- Meet the CEO and other executives to agree how technology supports business goals and growth plans.
- Review major technical designs and decide whether a proposed solution is feasible for the business.
- Set and track the technology budget, and decide which projects get people and money.
- Meet engineering managers and architects to review delivery, quality, risk and hiring.
- Assess new technologies, including AI, and decide which ones to trial or adopt.
- Speak with vendors, key clients and auditors about priorities, service levels and risks.

- Typically 10 to 15 years of experience in software or systems work, including several years leading large teams.

Common questions about a chief technology officer job
What does a CTO do?
A CTO decides the technology direction of an organisation and leads the teams that build and run its systems. The CTO also advises senior leaders on business opportunities that technology creates and manages the technology budget.
What is the difference between a CTO and a CIO?
A CTO usually focuses on the technology behind the organisation's products and services. A chief information officer usually focuses on internal systems and information. In smaller Singapore firms, one person often does both jobs.
How many years does it take to become a CTO?
Most CTOs have 10 to 20 years of experience, often with time as an engineer, architect and engineering manager. Founders of technology startups can reach the role much faster.
Does a CTO need to write code?
It depends on the size of the firm. In a small startup, a CTO often codes and designs systems. In a large organisation, the CTO spends more time on strategy, people and budgets, and less on code.
