Choosing the right programming language to learn can feel overwhelming. With so many options available, how do you know which one will lead to a lucrative career in tech? 

To answer this question, I've analyzed 150 job postings on LinkedIn across popular tech roles—from AI engineers to web developers—to uncover the skills that companies are actively seeking. In this blog, I’ll share the best programming languages for the 9 high-paying tech roles, ranked by average salary. 

Is AI Replacing Coders?

First, let’s address a burning question: Will AI replace coders?

AI technology is advancing rapidly, leading many to worry about the future of coding jobs. However, think of AI as a tool—like a calculator. Calculators didn’t replace the need to learn math; they simply made math more efficient. Similarly, learning to code provides a foundation that enables you to harness AI effectively.

Coding remains a foundational skill to learn even as AI becomes more integrated into the development process.

Choosing the Right Language for Your Career

To choose the best programming language, start by reflecting on what kind of tech career excites you. Don’t get caught up in job titles; instead, think about the work itself. Imagine your future self 10 years down the line:

  • What industry are you in?
  • What kinds of projects are you handling?
  • Would you enjoy the day-to-day tasks?

If you’re not sure, connect with real engineers to learn about their routines, challenges, and passions. You can also check out my YouTube interviews featuring tech professionals to gain insights into their experiences.

High-Paying Tech Roles and Their Top Programming Languages

1. Mobile Engineering

Mobile engineers specialize in creating apps for Android and iOS platforms.

Android Development

  • Average Salary: $104,010/year
  • Top Languages:
    • Kotlin: Preferred by 92% of companies due to its concise and efficient syntax.
    • Java: The native language for Android, still widely used but increasingly overshadowed by Kotlin.

iOS Development

  • Average Salary: $112,156/year‍
  • Top Languages:‍
    • Swift: Requested in 100% of job postings for its speed and seamless integration with Apple’s ecosystem.‍
    • Objective-C: Still relevant in some legacy applications but less common in newer roles.

Both Android and iOS development are solid career paths. However, as someone who spent eight years on WhatsApp, I’ll admit I’m not a fan of mobile development. Constant changes from Apple and Google often meant redoing features, which could feel frustrating.

2. Web Development

Web developers design and maintain websites, focusing on either front-end or back-end development.

Front-End Development

  • Average Salary: $115,697/year‍
  • Top Skills:‍
    • JavaScript: Adds interactivity and responsiveness to websites.‍
    • React: A JavaScript library that simplifies building complex user interfaces.‍
    • HTML: Provides the structure for web content.

Back-End Development

  • Average Salary: $110,379/year‍
  • Top Skills:‍
    • Python: Known for its simplicity and versatility.‍
    • Java: Ideal for enterprise applications and back-end systems.‍
    • AWS: A cloud platform crucial for deploying scalable applications.

Full-Stack Development

  • Average Salary: $136,609/year

Combining front-end and back-end skills makes full-stack developers highly valuable, especially as AI tools may automate many front-end tasks.

3. Data Roles

Data professionals analyze and interpret complex datasets to support decision-making.

Data Analyst

  • Average Salary: $95,323/year‍
  • Top Skills:‍
    • SQL: Essential for querying databases.‍
    • Python: Used for data manipulation and analysis.

Data Scientist

  • Average Salary: $115,643/year‍
  • Top Skills:‍
    • Python: Required in 100% of job postings.‍
    • Statistics: Critical for validating data trends.‍
    • Tableau: Popular for data visualization.

4. AI and Machine Learning

AI and machine learning engineers work on cutting-edge technologies, often commanding the highest salaries.

Machine Learning Engineer

  • Average Salary: $121,309/year‍
  • Top Skills:‍
    • Python: A must-have for building machine learning models.‍
    • Deep Learning Frameworks: TensorFlow and PyTorch.
