Why Technical Skills Alone Won't Promote You: 4 Career Levers for IT Engineers

Secret 1: Don't Be a 'Full-Stack Jack of All Trades' — Become a 'Technical Specialist'

The belief that a broader tech stack equals stronger competitiveness is a common trap. The author illustrates with two front-end engineers:

Xiao Zhou spent three years trying to "fill gaps": after front-end, he learned Spring Boot, then ops deployment. He ended up knowing a little of everything but mastering nothing — writing front-end less fluently than fresh graduates, producing buggy back-end code, and becoming a marginal "can do anything, but nothing well" team member.

A-Kai noticed the team struggled with "large-data table lag." He dove into front-end performance optimization — virtual lists, lazy loading, caching strategies. In six months he cut a 100,000-row table load from 5 seconds to 300 ms, becoming the department's "performance savior." Leadership assigned him the core project's front-end performance module, and his salary jumped 40%.

The industry lacks "people who can solve problems others cannot" in a specific domain, not "people who know a bit of everything." Even a perceived weakness (e.g., "doesn't understand business, only obsesses over tech") can be flipped: become a technical product manager who uses code thinking to break down business needs and technical solutions to deliver business goals — a scarce "tech + business" talent.

Key principle: Irreplaceability in IT comes not from perfection but from "others don't have it, others have it but I do it better."

Secret 2: Technical Excellence Must Be Visible to Decision-Makers

Backend engineer Lao Lin had solid skills — could build distributed systems independently — yet remained a mid-level engineer for five years. He assumed "good code speaks for itself." At an architecture review, the CTO asked how the system handles high concurrency; Lao Lin realized his disaster-recovery design was unknown to leadership.

In the workplace, your value is determined not by code quality alone but by how much "power holders" (leaders, CTO) recognize that your technology solves company problems. The author outlines three actionable steps:

Solve the leader's "technical pain points" proactively. If the leader worries about delays, do upfront technical research (new framework compatibility, third-party API stability) and present risks + solutions. If they worry about ops costs, demo an automation tool (Jenkins, GitLab CI) that cuts deployment from 2 hours to 10 minutes. This sticks better than "on-time code delivery."

Build a "reliable" reputation inside the team. Help colleagues debug by sharing log-analysis approaches. In weekly sharing sessions, walk through how you cracked a hard problem (e.g., "Using Redis to solve cache penetration"). Over time, peers say "go to him, he solves problems," and leaders hear it second-hand.

Establish a "technical brand" in the industry. No need to be an influencer. Write a Juejin/InfoQ article ("My Elasticsearch Log Analysis Practice"), open-source a utility library on GitHub, or speak at a local tech meetup. These "off-field actions" signal you're an industry practitioner, not just a company engineer, giving you priority at promotion time.

Secret 3: Stop Competing with Peers on Code Volume — Copy the Path of Those Already Ahead

IT teams often exhibit a "crab effect": engineers resent peers who get core projects ("they're just close to the boss"), dismiss technical articles as "fluff," nitpick variable names in code reviews to slow others down. Result: internal friction, slow projects, and leadership hires an external tech lead — nobody advances.

Real competition isn't pulling others down; it's making yourself better. Instead of comparing "who writes more code" or "who works longer hours," find a role model already in your target position.

If you want to be a tech lead, observe the CTO: how does he explain complex designs to non-technical product/ops? How does he balance "technical optimization" vs. "business deadlines"? How does he coordinate cross-team resources (e.g., getting ops to cooperate on deployment)?

Then move closer: request a 1-on-1, ask "I want to grow toward architect — what knowledge should I add now?"; volunteer as deputy on their project to learn requirement breakdown and task allocation. The strong have already avoided many pits; following them is 10× faster than fumbling alone.

Case: An intern initially competed on commit count. The author redirected him to shadow the architect on technical design docs. Six months later he could independently write architecture for small/medium projects and was hired as a senior developer — far ahead of peers.

Secret 4: Don't Let "Experience" Become a Shackle — Evolve with Business & Technology Trends

IT obsolescence is ruthless: Vue 2 → Vue 3 + Pinia in three years; monoliths → microservices even in mid-size firms; "years of CRUD experience" may be replaced by low-code platforms.

Many engineers stall because they turn "experience" into a cage:

A veteran stuck on Java 8 saying "new features aren't needed." When the company moved to cloud-native (Java 17 + K8s containerization), he couldn't keep up.

A front-end engineer only doing PC pages, refusing to learn mini-programs or mobile. When the business went mobile, he was relegated to peripheral tasks.

Career breakthrough = "evolve with business and tech trends":

Startup phase: Company needs "fast delivery." Focus on efficiency — scaffolding, component libraries.

Growth phase: Company needs "complex project ownership." Add "architecture design" and "performance optimization" — distributed systems, high concurrency.

Maturity phase: Company needs "team leadership." Learn "project management" and "technical management" — PMP, team OKRs.

A technical manager the author knows "refreshes his skill pack every three years": frameworks as a dev, architecture as a senior, management as an architect. "IT people can't live on old laurels; your ability must always match the company's current needs."

Final Takeaway

Climbing from "code tool" to the pyramid top relies not on "grinding code" or "tenure" but on mindset shifts :

From "fixing weaknesses" to "honing strengths" — find your irreplaceability.

From "heads-down execution" to "proactive visibility" — let leaders see your value.

From "watching peers" to "following the strong" — shortcut the learning curve.

From "relying on experience" to "continuous evolution" — stay in step with the industry.

The workplace isn't absolutely fair, but it is absolutely causal: every choice you make today decides your position tomorrow.
