From Engineer to Commercial Leader: A Roadmap for Technical Professionals

I didn't plan any of this. 

I'm a chemical engineer. I spent the early part of my career doing what engineers do - solving technical problems, building expertise, going deeper. The idea of moving into business development wasn't something I pursued. It happened because a client asked me a question I wasn't supposed to answer, and I answered it anyway. 

They wanted to know the cost impact of an alternative production strategy. Not my remit. But I understood the technical side well enough to see the commercial implications - so I walked them through it. The client engaged, asked more questions, and kept coming back. That conversation taught me something I've never forgotten: technical excellence only matters when it's connected to business outcomes. The moment you can make that connection in front of a client, everything changes. 

That was the beginning. What followed wasn't a smooth arc. 

The crossing is harder than it looks

The first challenge isn't capability - it's identity. Engineers are trained to have right answers. Commercial work rarely offers them. You're dealing with incomplete information, competing priorities, and decisions that have to be made before everything is known. For someone whose professional credibility has been built on precision, that ambiguity is genuinely uncomfortable. 

There's also the imposter syndrome. Early in the transition, I spent a lot of time thinking I didn't know enough about business to be in the room. What I eventually understood is that I knew things the commercial people didn't - and that was exactly why I was valuable. The crossing isn't about becoming a different person. It's about learning to use what you already have in a different context. 

The moment that recalibrated everything

We lost a bid I was certain we'd win. Our technical solution was excellent. The team had worked hard. The proposal was thorough. And we lost. 

When I went back and looked honestly at what had happened, the answer was uncomfortable. We'd solved the wrong problem. We understood the technical requirement perfectly - but we'd missed what the client actually cared about. Their real priority was somewhere else, and we hadn't asked the right questions to find it. 

The next pursuit, I changed my approach. Before we talked about technical solutions, I asked one question: what business problem are we actually solving here? It sounds simple. It changed how we worked from that point forward. We won. 

What the later stages actually feel like

As the transition deepens, the challenge shifts. It's less about learning commercial language and more about letting go of technical control. You can't do all the technical work yourself anymore. You have to trust others to deliver it while you focus on the relationship, the strategy, the next opportunity. 

That's harder than it sounds for someone whose professional identity has been built on technical mastery. The temptation is to stay close to the work you're good at. The growth happens when you resist that and focus on the level where you can add the most value. 

The other shift is in how you see accounts. Early in the transition, you manage relationships. Later, you start to see portfolios - where the white space is, what the client's three-year horizon looks like, how your capability positions you for what they'll need next. That's when the crossing is complete. You stop thinking about projects and start thinking about trajectories. 

What makes the difference

Looking back across 27 years, the technical professionals who navigate this well share a few things. They stay curious about the commercial side rather than defensive about the technical. They get comfortable saying "I don't know" in commercial conversations - and then going to find out. They find someone who's made the crossing before them and pay attention to what that person knows. 

That last one matters more than most people expect. The transition is learnable, but it's much harder to learn alone. A mentor who's been through it can save you from the mistakes that aren't obvious until you're already in them. A coach can help you see what's holding you back when you're in the middle of it and can't see clearly. 

The energy sector needs people who can bridge technical and commercial. That's not a motivational observation - it's a commercial reality. Companies leave significant value on the table because these two worlds don't connect. The people who can connect them are rare, and they're worth developing deliberately. 

If you're considering the crossing: you're probably better placed than you think. 

If you're in the middle of it: the discomfort you're feeling is the transition working, not failing. 

If you're stuck: the challenges you're facing are solvable. You don't have to figure it out alone. 

I've made this crossing. If you want to talk through yours, you know where I am.
