Why Strong Technical Skills Are Critical for CTOs and VP Engineers

What technical level should a CTO or VP of engineering have? Is there a definitive answer, or must they always be hands‑on technologists?

In China many R&D leaders are excellent managers but not necessarily strong technically, a paradox common in tech companies.

As software teams grow, top engineers are often moved into management roles, creating pressure to select the right people and leading to wasted or lost technical talent.

Does this affect project success? Absolutely. When deadlines loom, a CTO should still be able to write code, act as chief architect, and possess strong technical insight; a technical VP needs keen technical perception, and estimating technical ability should not be ignored.

There are five key reasons a great technology leader must have high technical competence:

Exceptional technical ability is the only way a CTO/VP can truly judge quality, distinguishing excellence in hiring and system design.

Technical knowledge enables balanced decisions on product quality, speed, release dates, and feature scope, forming the foundation of strong leadership.

Technical skill earns the respect of the entire team; without it, managers are seen as merely assigning fixes.

Highly technical leaders are passionate about technology, pushing boundaries and inspiring their teams with a sense of excitement.

Strong technical leadership attracts other top engineers, who prefer to work under leaders whose abilities match their own.

Consider a concrete example of how deep technical skill supports a leadership role.

Software bugs are inevitable; the battle for product quality never truly ends.

Engineering leaders must balance new feature development with maintaining quality and eliminating bugs, often coordinating with sales and other teams to resolve conflicting demands.

“You can’t improve what you don’t measure.” The first step in a continuous bug‑fighting plan is to define and measure software quality.

Identify the top 2‑3 things users truly care about—these must work flawlessly and with high quality.

For instance, Dropbox promises that users’ data will never be lost or corrupted; any failure destroys trust. Facebook, on the other hand, must ensure fast page loading across regions and network speeds, or users will abandon the product.

Thus, a CTO must first define clear, context‑specific quality standards for the product.

The next step is to adopt those standards and begin accurate measurement, which takes time, proper tooling, and patience.

Practically, teams should conduct weekly or monthly quality reviews to keep everyone aware of trends.

Technical leaders must be confident in the goals they set.

Once confidence is established, they can set a non‑negotiable quality “red line” that must never be crossed.

The CTO/VP must understand where that red line lies, recognize warning signals, and know how to stay clear of it.

If quality falls below the threshold, all work stops until improvements are made, which can cause friction with product managers and CEOs.

When other leaders trust the CTO’s technical assessment, enforcing discipline becomes much easier.

For example, as Dropbox’s engineering team grew, bug counts in the desktop client rose dramatically because the codebase had not been architecturally expanded to accommodate new engineers.

Addressing this required a major refactor that would take six to nine months, but it was necessary to move the red line farther away and enable continuous quality improvement.

Such situations demand company‑wide trust in the technical leadership’s vision for change.

Speed is crucial for startups, yet a CTO/VP must also know when to slow down to ensure sustainable growth.

When rebuilding the desktop client architecture, the team progressed through the “bug‑battle” steps, continually raising quality standards in each roadmap/OKR cycle.

Ultimately, the CTO establishes a lasting workflow that keeps the core product stable.

Finally, many founders question the value of a CTO’s technical ability during hiring. A striking statistic shows that many underestimate the importance of a programming interview.

Therefore, CTO/VP candidates should pass the company’s coding interview and demonstrate outstanding technical proficiency, alongside strong people‑management, collaboration, and hiring skills.
