How to Grow into a Qualified CTO: Essential Skills and Strategies

We first define the concept of a CTO (Chief Technology Officer) as the technical leader of a company. While the role at large enterprises like Alibaba differs greatly from that in smaller firms, the discussion here focuses on CTOs in relatively small companies, where the person who makes all technical decisions essentially fulfills the CTO role regardless of title.

A qualified CTO in a startup with fewer than ten engineers must be able to independently handle technical work, understand the CEO’s business intent, quickly turn ideas into product implementations, build a team that matches the company’s growth needs, and lead the team to deliver quality products on schedule.

For a “regular” technical professional—defined here as someone with 5‑8 years of experience who can independently handle tasks in their specialty (e.g., backend development, system design, RESTful APIs) and has led small teams or projects—the author strongly recommends taking on technical leadership positions, whether leading a project or becoming the technical head of a small company.

Rapid growth comes from confronting and solving difficult problems. If a year’s work feels routine and merely repeats past experience, true growth is limited. By stepping out of the comfort zone, tackling unfamiliar challenges, and solving many issues—ideally dozens per year—an engineer accelerates their experience and value.

The author lists six essential capabilities for a qualified CTO:

Communication and comprehension : Ability to quickly and accurately grasp the CEO’s and product manager’s intentions.

Business sense : Combine technical excellence with market viability to create products that can be sold.

Product planning : Assist product teams and CEOs in shaping product roadmaps, especially when a dedicated product director is absent.

Team management and mentorship : Build and nurture a technical team, recognizing that talent is developed through the right environment and guidance.

Technical problem‑solving : Overcome challenges beyond the team’s current capabilities, such as security, performance, and reliability issues.

Influence building : Establish personal and team reputation both inside and outside the company to attract talent and foster growth.

Beyond these, individuals may have additional skill requirements. The author invites readers to share further insights to help technical professionals grow purposefully.
