Intro AI is changing engineering faster than any tool before it ever has. In just a few years, we’ve gone from writing every line of code ourselves to seeing AI-assisted engineering as a standard way to build software. That shift has created a lot of uncertainty. Many people are asking themselves what skills will still be valuable, how the roles will evolve, and if relying on AI will help them grow or make them too dependent on it. But AI isn’t just a tool for writing code faster. It can also be one of the most powerful tools for learning. The key is knowing how to use it effectively. In this article, you’ll learn how high-performing engineers and engineering leaders use AI to learn faster. More importantly, you’ll learn the mindset behind these workflows. Let’s start! My upcoming book “The Multiplier Mindset” published by O’Reilly This article is an adapted version of one of the chapters of my upcoming book called “The Multiplier Mindset”, published by O’Reilly. The book will be published soon, and is available for pre-order! There are 3 Types of Engineering Professionals Using AI When it comes to using AI, most engineers and engineering leaders fall into 3 camps: - Refusers These are the engineers who refuse to use AI altogether because they don’t trust it. They tend to be more experienced people who have seen a lot of shifts in the industry. They are reluctant to change, preferring to stick to what they know and are good at. Their mindset is “It has worked well for me for 15 years, so why would I change it?” But this attitude can stop people from learning new things and improving their craft. - Overreliers These are the people who rely on AI tools so heavily that they stop thinking critically and become less effective. They are often less-experienced engineers who have a good grasp of the AI tooling landscape. But their overreliance on AI tools often results in mediocre work. Worse, some don’t even check whether the AI output they’re using is aligned with the team’s standards! This forces reviewers to do the work of finding all the problems, which can take a lot more time than if the engineers had done the task properly right from the start. - Multipliers These are the engineers and engineering leaders who see AI as a way to multiply their efforts, not to replace their expertise. They use it to eliminate repetitive work, learn faster, explore more ideas, and spend more of their time on the problems where human judgment matters most. They are also the ones who have the greatest impact. You want to be in the multiplier camp: approaching the “fancy new tool” with curiosity, not unearned trust. You need to be keen to try out new things and learn but hold tight to good engineering fundamentals and practices. You should delegate your busywork, not your judgment calls. You should use AI to help you think at a higher level, because that’s what becoming an engineering multiplier is all about. The following sections look at how to multiply your impact on important tasks using AI. How Multipliers Use AI to Learn Faster To learn new things significantly faster, you need a good understanding of engineering practices and the resourcefulness to leverage different resources to get what you need. Great engineers don’t spend hours trying to understand a codebase by going through it file by file or reading every word of the documentation. They use AI to help them quickly understand the unfamiliar parts of the codebase and get an overview of its architecture, APIs, and any other relevant things. Here are some examples. Onboarding to New Codebases Using AI can help you understand a codebase in hours. Jeff Morhous, a senior software engineer working in the healthcare industry, wrote a guest article on the Engineering Leadership newsletter about how he uses AI when he needs to work with a new codebase. He laid out a four-step process, which I summarize in this section. Step 1: Use /init to get the big picture If the codebase already has a CLAUDE.md and/or an AGENTS.md file, read through them. If not, run Claude Code’s /init command. It will skim through the codebase and document its understanding of the most important features in CLAUDE.md. Use a higher-tier model when you run /init, even though it will cost you more tokens. Tokens spent on reasoning up front are tokens well spent. Using Plan Mode with a cheaper model like Sonnet, makes the plan more likely to overlook critical architecture or contain consequential mistakes. More reasoning-heavy models, by contrast, often come up with things you wouldn’t have thought of on your own. Step 2: Map the architecture It’s wise to produce a map of the repository early on to help you understand the system’s major components, responsibility boundaries, and dependencies. Here’s a prompt you can use to do this: You are onboarding me to this repository. Tasks: - Identify the top-level architecture (apps/services/libraries) and what each does. - Produce a directory map: top 10 directories with responsibilities. - Identify key runtime boundaries: API layer, domain layer, persistence, async jobs, config. - Show a dependency diagram (Mermaid) using the repo’s actual module/package boundaries. - Cite exact files for each claim (paths + brief evidence). Constraints: - Do not edit files. - Prefer reading docs first (README, AGENTS.md, CLAUDE.md, docs/, CONTRIBUTING, ADRs) and then code. - If the repo is a monorepo, explain the workspace/tooling setup. Diagram: Create a Mermaid diagram with your findings. Step 3: Identify the testing strategy If you want to understand the test pyramid in your app and build confidence quickly, you should identify your app’s testing patterns right away. Here’s a prompt you can use for that: Identify the testing strategy in this repo. Output: - Where tests live and how they're organized (unit/integration/e2e). - The fastest local confidence loop: which commands to run before a PR. - How fixtures/mocks/test containers are handled. - Common failure modes in this repo's tests (if visible from config/docs). If there is no testing strategy, propose a plan for one that follows the testing pyramid (lots of unit tests, less e2e tests). Step 4: Run the app If you don’t already have the app up and running by now, you’ll want instructions. Ask for setup steps with this prompt: Produce a repo-specific local setup checklist with commands. Rules: - Only include steps you can justify from files in the repo (README, Makefile, package/build files, scripts, devcontainer config). - Include: required runtimes, dependency install, env vars, database setup, migrations/seeds, and “run server / run worker / run UI”. - End with a smoke test of one key flow. This should give you a single “happy path” setup that ends with a running service and a verification step. Learning a New Framework or Programming Language More and more of the engineers I speak with are becoming tech-agnostic these days. The separation between frontend and backend continues to blur. The same holds true for different programming languages. If you are good at working with a certain technology, you likely have a good understanding of its engineering fundamentals and specific patterns. You can much more easily learn new tech using AI because the concepts are quite similar, while the syntax is different. If you are an expert in Python, you can apply your knowledge in combination with AI to be productive in Java and PHP, and the same goes for a lot of other programming languages and frameworks. Once you have a good understanding of one specific tech, you can utilize AI to become good at others if you need to. For example, imagine you’re an experienced Python engineer who needs to work on a Java project. You start by giving AI the context about yourself. You can use a prompt like this: I'm an experienced Python engineer and need to become productive in Java. Explain the most important differences, using Python concepts I already understand. Focus on the things most likely to surprise me or cause mistakes. As your next step, you can be more specific about the actual work that you do. If you’re joining a new project that uses Spring Boot, you might use this prompt: I know how to build REST APIs with FastAPI. Show me how the same concepts work in Spring Boot, including routing, dependency injection, validation, database access, and error handling. From there on out, use AI while working to get explanations of unfamiliar code and review your code for potential mistakes. Building Hands-On Projects For the past decade or so, watching a tutorial video has been the standard way to learn a new technology. Instead, try using AI to help you understand certain parts when you are building. Make sure to ask why certain things are the way they are. You can start much like you would if you were learning a new framework, except this time your goal is to learn by building. Let’s say you are an experienced React engineer and you want to get up to speed with Angular. You can start with this prompt: I'm an experienced React developer learning Angular. I want to build a simple TODO app with CRUD functionality. Create a plan that will help me learn Angular while building it. Don't write the code yet. This is where the plan mode of your favorite AI coding tool can come in handy. Review proposed plan and architecture, then start asking questions like this: Why would you structure the application this way? How is this different from how I would typically structure a React application? Then, I strongly suggest that you build the project one part at a time. Don’t just try to “one-shot” it and hope for the best. Use AI as a learning partner. If you see a pattern you don’t recognize, that’s when you should ask why that pattern is there, what the possible alternatives might be, and, of course, how that pattern relates to the concepts you already understand. Additionally, you can use AI to review your code. A prompt for this might look like the following: Review this code as an experienced Angular engineer. What am I doing that works but isn't a good practice in Angular? Explain why and show me how an experienced Angular developer would approach it. The goal is for you to understand and learn, so don’t try to optimize for having AI write as much code as possible. Focus on the decisions about WHY certain code should exist and HOW it affects the whole system. How to Use AI as a Thinking Partner Conway’s law tells us that the structure of a software system mirrors the communication structure of the organization that builds it. Perhaps that’s why people in the software industry have to solve so many difficult problems that involve both tech and human beings. You can use AI as a thinking partner by prompting it to challenge your assumptions, provide alternatives, and identify what you’ve missed. Here are some ways to do that: - Share a tech spec or architecture decision record with a large language model (LLM). Ask it to stress-test the idea. - Prepare for a difficult conversation with stakeholders or your manager by drafting a script of what you want to say and then asking the LLM to give you feedback and help you refine it. After you refine the script, rehearse it out loud until it comes naturally! - Share a specific problem, explaining it as clearly as possible, and ask the LLM to share ideas for solutions. Striving to explain the problem to an LLM clearly not only yields better solutions but also refines your understanding. - Ask AI to review your writing. Apply its proposed changes manually so that you can think them through and adjust them to fit your own voice and style. Last words Let’s end this article with the following: The goal of engineering has never been to do everything yourself. Engineers have always used tools to free up their time for higher-leverage work, and LLMs are just more powerful tools whose outcomes are much less predictable. So, use them to your advantage, especially to learn something new faster! You got this. Liked this article? Make sure to 💙 click the like button. Feedback or addition? Make sure to 💬 comment.
