Artificial intelligence is completely changing the world; it has already revolutionized multiple industries across the internet, whether it is digital marketing, software development, or business operations. According to DemandSage, 40% of companies worldwide are already using AI in their operations, and a staggering 99% of Fortune 500 companies use AI. The global artificial intelligence (AI) market is estimated at USD 371.71 billion in 2025 and is projected to hit $4.8 trillion by 2033, according to UNCTAD.
The global AI market size will grow for sure, and if you want to take advantage of it and take part in this growth, right now is the perfect time for you to start building your career in AI. Or if you are already eyeing a career in AI, but don't know where to start? Founder of DeepLearning.AI, Andrew Ng's e-book can be the practical guide that will tell you how to start and build a career in AI.
To start a career in AI, you don't need a PhD, a mountain of GPUs, or a perfect plan; you need a clear path, consistent habits, and projects that grow with you. Start small, learn continuously, and let each win start the next new journey.

The simple roadmap: Learn → Build projects → Job
Across thousands of learners and teams, a practical three-step arc shows up again and again: build foundations, apply them through projects, and then run a focused job search.
- Learning Foundational Skills: This is the bedrock. Before you can build, you must understand the tools. This doesn't mean you need to become a theoretical mathematician, but a solid understanding of key concepts is important.
- Working on Projects: This is where theory meets practice. Projects are your playground for experimentation and your portfolio for showcasing your abilities. They transform abstract knowledge into real skills and show your value to potential employers.
- Finding the Right Job: With a solid foundation of skills and a portfolio of projects, you're ready to find your place in the AI ecosystem. This phase is about strategically navigating the job market to find a role that fits with your skills and career goals.
However, the most important thing is you don't outgrow any stage, as learning continues while you build projects, and projects continue while you job hunt. It is always helpful to keep a supportive community close; it compounds everything.
Here is the breakdown of all 3 steps on how to start and build a career in AI:
Step 1: Learn the right things (and keep learning)
The first step is to prepare yourself with the right knowledge. While the field of AI is massive, you can focus on a few key areas to build a strong technical foundation. The goal isn't to know everything, but to learn the core concepts that will allow you to solve real-world problems.
- Foundational Machine Learning: Get to know the workhorses of AI, such as linear and logistic regression, decision trees, and neural networks. More importantly, understand the basic principles behind them, like the trade-offs between bias and variance, and how to analyze errors.
- Deep Learning: This subfield of machine learning has been the driving force behind many of AI's recent breakthroughs. Understanding the basics of neural networks, including convolutional networks (for images) and sequence models (for text), is invaluable.
- Relevant Math: Don't let the word "math" intimidate you. A practical understanding of linear algebra (the language of data), probability, and statistics is more important than theoretical expertise. These mathematical tools will help you understand how and why models work.
- Software Development: To bring your AI models to life, you'll need to write code. Familiarity with Python, the lingua franca of AI, and key libraries like TensorFlow or PyTorch is important. Understanding data structures and software design principles will help you stand out.
A frequent worry: "Do I need a lot of math to get hired?" Useful math helps you debug and reason, but the depth you need depends on your role and the maturity of the stack you're using. Learn enough to make good decisions; go deeper as your work demands it.
Remember: Prioritize concepts you'll use to make decisions on real work. Foundations matter more than chasing every new paper.
Step 2: Build projects that actually matter
Knowledge is potential, but projects are proof. Building a portfolio of projects is arguably the most critical step in starting your AI career. It's how you deepen your skills, show your capabilities, and create real-world impact.
- Start Small: Your first project doesn't need to be a groundbreaking discovery. Re-implementing a known algorithm or applying machine learning to a personal hobby are great ways to start. The key is to begin and build momentum.
- Scope for Success: A successful project starts with a clear business problem, not an AI problem. Identify a real-world challenge, brainstorm potential AI solutions, assess their feasibility, and set clear milestones.
- Show Progression: Your portfolio should tell a story of your growth. Start with class assignments, then move on to personal projects, and eventually, try solving more complex problems that create real value. This progression shows your ability to learn and take on increasing responsibility.
- Adopt the "Ready, Fire, Aim" Approach: Building AI models is an iterative process. Instead of getting stuck in "analysis paralysis," it's often better to jump in (Ready, Fire, Aim), build a quick end-to-end prototype, and learn from your mistakes. This hands-on approach allows you to find what works and pivot quickly.
Remember: A great AI career is built on shipped projects, not just certificates.
Step 3: Start your career and find the right job
With a solid understanding of the basics, a skill set, and a compelling portfolio, you're ready to enter the job market. The key is to be strategic and capitalize on your unique background to your advantage.
- Switch Roles or Industries, Not Both: If you're new to AI, it's easier to switch either your role or your industry, but not both at the same time. For example, an analyst in the financial sector could transition to a data science role within the same industry, capitalizing on their domain expertise.
- The Power of Informational Interviews: The AI field is ever evolving, and job titles can be inconsistent, so it will help you if you start talking to people in roles and companies that interest you. These informal conversations are a great way to understand what a job truly requires and what skills are most valued.
- Nail the Fundamentals: A polished resume, a strong portfolio, and solid interview preparation are non-negotiable. Customize your resume/ job applications, practice common interview questions, and prepare yourself to discuss your project details.
- Build Your Community: Networking isn't just about shaking hands at events; it's about building genuine connections. Your community can provide support, advice, and referrals, so don't be afraid to ask for help and be willing to pay it forward.

Mindset for a successful career in AI:
Your mindset is the important thing, regardless of the task you are doing, and depending on the task, you'll need a certain type of mindset. It is no different when you are starting and building a career in AI. Here's the mind you should have:
- Community over "networking": You don't need to "work the room." Instead, you should contribute to groups you care about; generous peers can become your unfair advantage.
- Discipline > intensity: People won't see your Saturday night study session, but they'll see your compounding skill and projects.
- Imposter feelings are normal: Most of us have wondered if we belong, even after building serious projects. If you want to be here, you belong here. Help someone one step behind you; it reinforces your own progress and lifts the field.
- Make days count: Careers are long, but days are finite. Spend more of them learning, building, and helping.
In Conclusion:
A successful career in AI is about more than just technical skills. It's about teamwork, communication, and personal discipline. It's about overcoming imposter syndrome, that feeling that you're a fraud. The AI community is growing, and there's a place for everyone who wants to be a part of it.
A career in AI isn't a straight line; it's a series of loops: learn, build, reflect, and then repeat at a higher level. Start with the skills that help you make decisions. Ship projects that matter to someone, not just to your repo. Let your portfolio tell the story of rising scope and impact.
When doubt creeps in, remember: everyone starts small. Take the smallest step you can actually take today and keep moving forward. That's how real AI careers are built.
