Becoming the CEO of Apple is obviously a big deal. But if you are thinking about your own career, the more interesting question is not what happens after you get the top job.
It is what you did for years before anyone handed it to you.
That is what makes John Ternus’ career worth studying. Apple announced on April 20, 2026, that Ternus would succeed Tim Cook as CEO, effective September 1, 2026, following a long-term succession process unanimously approved by the company’s board. Cook moved into the role of executive chair. Ternus is now Apple’s New CEO and also serves on its board. You must have seen him in the launch of iPhone Duo i.e. the foldable iPhone!
He did not suddenly appear from outside the company with a flashy résumé. He spent roughly 25 years inside Apple, moving from the product design team into increasingly important hardware leadership roles.
So, before you focus on the CEO title, look at what came before it. That is where the useful lessons are.
John Ternus’ Career At A Glance
| Career Milestone | What To Know |
| Joined Apple | Joined Apple’s product design team in 2001 |
| Early background | Previously worked as a mechanical engineer at Virtual Research Systems |
| Senior hardware role | Became Vice President of Hardware Engineering in 2013 |
| Executive role | Became Senior Vice President of Hardware Engineering in 2021 |
| Key responsibilities | Oversaw hardware engineering across major Apple product categories |
| CEO appointment | Announced April 20, 2026; became CEO on September 1, 2026 |
Apple credits Ternus with overseeing hardware work across products including iPad, AirPods, iPhone, Mac and Apple Watch.
Lesson 1: Build Expertise Before Chasing The Top Job
Ternus spent decades building deep hardware experience before becoming CEO. He joined Apple in 2001, became a vice president in 2013 and joined the executive team in 2021.
That is where the first lesson for you comes in.
You do not always need to become a manager as quickly as possible. Sometimes, becoming exceptionally good at something is what eventually puts you in the strongest position to lead.
Takeaway: Before chasing a bigger title, build skills that make you difficult to replace.
Lesson 2: Stay Close To What Your Company Actually Builds
Ternus’ career has been deeply connected to Apple’s products. Apple says he was instrumental in new product lines including iPad and AirPods and worked across generations of iPhone, Mac and Apple Watch.
You do not need to work in engineering to use this lesson.
If you work in marketing, understand the product. If you work in sales, know how it actually works. If you are in finance or operations, understand what customers are paying for.
Takeaway: Your job description may define your role, but understanding the product makes your contribution more valuable.
Lesson 3: You Don’t Have To Be The Loudest Person In The Room
For much of his Apple career, Ternus was far less publicly visible than many famous technology executives. His public profile grew as his responsibilities increased, including appearances connected to Apple product launches.
That matters because career visibility and constant self-promotion are not the same thing as leadership.
Ternus’ rise was built inside an organisation where his technical responsibilities kept expanding over time.
Takeaway: Being noticed matters, but consistently doing important work can matter even more.
Lesson 4: Learn To Work With People Who Know Things You Don’t
Apple’s hardware organisation is not built around one person knowing everything. Hardware engineering requires specialists working across design, systems, reliability, materials and other areas.
Apple itself describes the hardware organisation as working closely with industrial design, hardware technologies, software engineering and operations.
That is a useful reminder for your own workplace.
You do not become a stronger professional by pretending to have every answer. You become stronger when you know how to work with people who bring expertise you do not have.
Takeaway: Your value is not only what you know. It is also how well you can bring different expertise together.
Lesson 5: Think In Years, Not Just Quarters
Ternus spent years moving through Apple’s hardware organisation before reaching the executive team and eventually the CEO role.
That kind of progression is a useful antidote to the obsession with instant career success.
The Mac’s transition to Apple silicon, for example, was one of the major technology shifts Apple was working through when Ternus led hardware engineering. Apple described him as a key leader in that ongoing transition.
Some work takes time before anyone sees the result.
Takeaway: Not every important career move will pay off immediately. Build for the position you want to hold years from now.
Lesson 6: Take On Bigger Responsibilities Gradually
There is a clear pattern in Ternus’ Apple career: engineer, vice president, senior vice president, then CEO.
The point is not that everyone should wait 25 years for a promotion. The point is that responsibility expanded before the title reached its highest level.
Think about your own career for a moment. Are you already doing work that belongs to the next level?
Takeaway: The strongest case for a promotion is often evidence that you are already capable of handling more.
Lesson 7: Learn From Every Product Cycle
A long career in hardware means living through repeated product cycles. New products are designed, tested, launched, improved, and replaced.
Apple credits Ternus with work across multiple generations of iPhone, Mac, iPad and Apple Watch, rather than attaching his career to a single product.
That is useful because your career should not depend on one project going perfectly.
A campaign can underperform. A launch can disappoint. A project can go nowhere.
If you understand what happened and improve because of it, the work was not entirely wasted.
Takeaway: Do not judge every project only by the result. Ask what it taught you for the next one.
Lesson 8: Communication Matters As Much As Expertise
Technical knowledge is valuable. Explaining it clearly is another skill entirely.
Ternus has increasingly represented Apple’s hardware work publicly, and his move into the CEO role has made communication an even larger part of his responsibilities. His first major Apple event as CEO came shortly after he formally succeeded Cook.
You can be brilliant at your job and still struggle if nobody understands your ideas.
Takeaway: Learn to explain complicated work simply. Expertise gets stronger when other people can understand and act on it.
Lesson 9: Don’t Rush To Prove Yourself
Modern careers can make slow progress feel like failure.
Someone changes jobs every year. Someone else becomes a manager at 28. Another person announces a new title on LinkedIn.
Then you look at your own career and wonder whether you are behind.
Ternus offers a different example. He joined Apple in 2001 and spent years accumulating technical and leadership responsibilities before becoming CEO in 2026.
Career growth can be cumulative rather than dramatic.
Takeaway: You do not need to look successful every six months. You need to keep building work that adds up.
Lesson 10: Your Track Record Can Speak For You
This may be the biggest lesson of all.
Ternus did not become Apple’s CEO because his career began on September 1, 2026. That date was simply when the title changed.
The evidence had been building for years through hardware leadership, expanding responsibilities and work across Apple’s major product categories. Apple described his deep technical knowledge and focus on creating great products as central reasons for the board’s confidence in him as Cook’s successor.
If you want a bigger role tomorrow, start building the evidence for it today.
Takeaway: Do not wait for the title to start acting like someone capable of earning it.

The interesting part of John Ternus becoming Apple’s CEO is not simply that he reached one of the biggest jobs in business.
It is that the title came after years of expertise, increasingly complex responsibilities and work that gave Apple a reason to trust him with more.
You probably are not trying to become Apple’s next CEO. But you do not need to.
The useful question is much closer to home: What evidence are you building today that will make someone trust you with a bigger opportunity tomorrow?
Because when the opportunity finally arrives, your résumé should not be the beginning of the story.
It should be the proof that you have been preparing for it all along!
