Presenting Peter Mukherjee
Peter built a London business from scratch in 1992, grew it into an international franchise network with a public listing, and lost most of it to the 2008 crash. He reinvented himself as a professional architectural photographer and worked at it for fifteen years before retiring in 2023 to write full-time.
I’ve known Peter Mukherjee for about an year now, and he’s one of the wisest people I’ve ever talked to.
The whole time he was talking during our conversation, I kept hearing the same diagnosis for why most senior engineers hit a ceiling.
You are managing your career like an employee.
The people who break through manage it like a business. They use a different vocabulary, run a different operating system, and make different decisions. None of it requires another certification, and all of it requires a mindset shift most senior engineers never make.
Forced Pivots Surface The Rest Of You
The default for a generation was 30-40 years at one employer, a stable pension, and a CV that looked sensible. The world does not work that way anymore. Multiple careers across one working life is now the norm.
The hardest version is the forced pivot. Income stops, status stops, and everything you built is on hold while you scramble to establish something new.
Getting through it requires confidence in your own abilities, because most people are more capable than they give themselves credit for, and the work is digging deep, finding the talents you have, and pulling yourself through.
Resilience is built mostly through failure. There is no shortcut. You learn the most during the times you fail, because failure forces you to dig in and recover. The worst response is going negative, looking backwards, sliding into “what have I done“. That posture stops the recovery before it starts.
The deeper insight is that most people never find out what their real talents are. They pick the first thing they think they are good at and develop only that.
There might be tens of thousands of people with that level of athletic talent who never find out they run, because they never explored their full range. When things go wrong, you are forced to ask “what else am I good at?“ That question, under pressure, surfaces the talents the comfortable version of you never bothered to look for.
The Old Leadership Model Is Finished
The safe pair of hands is done. Steady the ship, grow dividends 5-8% a year, stay around for ten years. That mindset takes the business backwards now, because the world moves too fast for it. Standing still is moving backwards.
The replacement is the transformational leader. Transformation involves risk-taking, which only works if the culture supports it, which means giving your people permission to take risks too, without making them fear for their jobs when they get something wrong.
Apple and Google run open plans where managers sit among their people. Senior managers might have an office, but it is glass-sided so people see them and they see their people. Any transformational leader has to be able to carry their people through change, and you only carry them properly if you are visibly involved with them.
A successful US business leader who talked about being vulnerable in front of her people in the 90s was told “that’s because you’re a woman“. Now every leadership conversation centres on empathy and vulnerability. COVID accelerated it and AI will accelerate it further.
Where Leaders Lose People
The biggest source of failure is arrogance and ego, and the biggest organisational consequence is losing the people you invested time and money into developing. You will always be outbid on salary. There is always someone offering more money.
But the one thing people put ahead of the bigger paycheque is enjoying where they work. The manager who is arrogant, ego-driven, and disconnected from their team creates an environment people are eager to leave, and that manager loses good people on a clock.
Humility Is The Hardest Lesson
The kind of humility forced on you by having to let go of people who built the business with you. Telling someone who has been with you for 15 years that the business is closing is one of the hardest things a leader does.
There are two ways to handle it. The first is matter-of-fact, because that is what organisations do. The second is to treat the moment with the weight it carries for the person on the other side of the desk, with empathy and active care for what happens to them next, including helping them frame what they learned.
The relationships survive the second version.
The same principle runs through every other team interaction. Make people feel included, valued, recognised.
A specific mechanic that works: team-level bonuses where the team itself decides who the top contributors are. Everyone shares in the reward, but the team picks the largest pieces. It does not have to be financial. A day out, a big dinner, share options. The point is structuring recognition so it incentivises working together instead of competing.
The 51/100 Rule
The mythology of the successful CEO making lots of right decisions is wrong. Every CEO is making decisions every day, and some they get wrong, sometimes catastrophically.
The batting average, from Ursula Burns (former CEO of Xerox, started as an intern): out of every 100 decisions, you make 51 good ones and 49 bad ones. The job is making sure the 49 bad ones are not too bad.
You afford one or two howlers, but the rest need to be recoverable. If you have an immaculate record of getting everything right, you are not taking enough risk, and your career is moving backwards while you congratulate yourself for being right.
The mechanic underneath is reversibility. Good risk-taking is calculated, not suicidal. Sort every decision into reversible and irreversible. The reversible ones get volume. The irreversible ones get contingency planning.
The downside in the reversible bucket is embarrassment and a week of recovery. The downside in the irreversible bucket is structural and measured in years.
Most senior engineers treat every decision as if it were in the irreversible bucket. They spend two weeks deciding whether to submit a conference talk. They draft a LinkedIn post and never publish it. They workshop an internal proposal until the moment to make it has passed. The cost is invisible because nothing went wrong. Nothing happened at all.
Stop collecting advice. Start operating differently.
I share the exact playbooks that helped me become Head of Data, negotiate a 40% raise, and survive 4 M&A transactions. Paid subscribers use them to get promoted.
Curiosity Is The Response To Uncertainty
For individuals, the best response to uncertainty is curiosity. Nobody becomes successful without it. Learning does not stop when you finish university. Curious people are the ones who do something big.
Invest in emotional skills. Degrees matter less. The capability to communicate, manage people, be visionary, be inspirational, and bring creativity is what employers will look for. Those are the skills that differentiate you in three years’ time, and they are the ones currently at risk from the AI-as-co-pilot trap.
The AI Entropy Warning
Entropy is a real thing. Systems decay toward their lowest energy state when nothing pushes back. Brains are a system. The muscle you stop using is the one that atrophies. People who used their brains for the work are now using AI for the work. The output looks fine. The brain underneath is going to sleep.
The fix is using the tools while keeping the thinking. Let AI draft, then edit by hand, let it summarise, then read the source or let it suggest options, then make the decision yourself and write down why.
The skills that cannot be outsourced are the ones the technical job market will pay for in three years, and right now the industry is volunteering for neglect.
Load The Dice Yourself
Every successful person credits luck. A specific phone call, a meeting, a door that opened at the right moment. A single phone call was the pivot for a multi-billion-dollar career, where the answer was 50-50 right up until it was given. The mistake is to hear that and conclude luck is random.
Luck is a numbers game with a rigged distribution. Go to one networking event a year and talk to three people you already know, you have three lottery tickets. Go to five events and talk to ten new people each, you have fifty. Same person, same skills, sixteen times the surface area for a lucky break.
For data engineers, the equivalent is volume of visible work. Internal documents that travel. Brown bags and lightning talks. External writing. Conference submissions. Every one of them is in the reversible bucket. The hit rate on any individual piece does not matter. The volume across all of them does.
The wider pattern shows up in every successful career: luck plus passion. Everyone talks about their passion for what they do, and there is a direct correlation between success and finding it. “Follow your passion” only works if you have one. If you have not found one, the work is exploration. Keep looking until you find the thing you love. Until then, every step is a stepping stone.
The cost of getting this wrong is what makes the rest of it urgent. The greatest risk is that you never find success and fulfilment because you stuck with something you did not love.
Sir Clive Woodward, the England rugby head coach who won the 2003 World Cup, put it this way:
The worst thing that happens in life is getting older and looking back thinking “I wish I’d taken a chance on that“
Treat Yourself As A Business Inside The Organisation
Change your perception of your role. You are no longer “the programming manager.” Look at yourself like a one-person business inside the organisation you work for. Promote yourself. Acquire the skills. Develop yourself the way a business develops.
The language change shows it:
Saying “I am an admin manager, I have been doing this for seven years“ tells the listener nothing.
Saying “in the last seven years I have organised X, I have done Y, these are the successes, these are my strengths, this is where I add value, these are the things I will carry forward to help your organisation“ is a different conversation.
That is how you communicate inside the organisation. That is how you describe yourself outside it.
Life is like snakes and ladders. You roll the dice, you move forward. Lucky, you climb a ladder. Unlucky, you slide down a snake. The mistake is to think your future is dependent on the roll of the dice. Most people are more in control of their destiny than they think.
Too many expect someone else to design their career. The alternative is to go out, meet people, decide your own projects, decide your own career.
I built the resource library I wish existed when I was 25 years old.
Career scripts. Business translation templates. Stakeholder playbooks. Meeting frameworks.
Every single one came from real situations, real mistakes, and real results. Paid members get the whole thing.
Final Thoughts
The senior engineer ceiling is not built out of skill gaps. It is built out of an operating model imported from the codebase: optimise for being right, ration the decisions, stay invisible until you are sure. That model breaks the moment the job stops being primarily technical, which is the moment the ceiling appears.
The people on the other side run a different model. They aim for 51 out of 100, sort decisions before they spend time on them, and surround themselves with people better than they are.
They take humility seriously and ego personally. They keep their brains on while the industry switches theirs off. They describe themselves like a business that knows what it sells.
None of it requires a certification. All of it requires the mindset shift most senior engineers never make.
