Most engineering leaders have lived through some version of this experience: a team assembled with impressive résumés, deep technical expertise, and years of experience, yet the project still struggles.
Deadlines slip. Design discussions drag on longer than expected. Decisions feel harder than they should be. Despite having all the right talent on paper, progress slows and frustration grows.
The disconnect is rarely about intelligence or effort. More often, it comes down to something far less visible and far more important: team chemistry.
Teams Are Systems, Not Individuals
Engineers are trained to think in systems. We know that optimizing individual components does not automatically produce a high-performing system. The behavior of the whole depends on how the parts interact, not just how well each part performs in isolation.
Engineering teams operate the same way. A group of highly capable individuals can still underperform if communication is strained, trust is low, or people work in silos. Conversely, teams with strong chemistry, where members communicate openly, challenge assumptions respectfully, and align around shared goals, often outperform teams with far more individual star power.
Team performance is an emergent property. It arises from interactions, not résumés.
The Hidden Cost of “Brilliant Jerks”
Many organizations encounter the “brilliant jerk” at some point. The term ‘brilliant jerk’ is a commonly used phrase in leadership and organizational research to describe this pattern, not a personal judgment. This isn’t always someone who is overtly toxic. More often, it’s an engineer who is technically exceptional but difficult to collaborate with.
They tend to dominate conversations, shut down alternative viewpoints, or focus on being right rather than on building shared understanding. Individually, they may deliver impressive work. Systemically, however, they introduce friction that spreads quietly through the team.
Over time, others become hesitant to speak up. Junior engineers stop asking questions. Design discussions turn defensive. Knowledge concentrates instead of flowing freely. Innovation slows, not because the team lacks ideas, but because people no longer feel safe contributing them.
The real cost of the brilliant jerk rarely shows up on a performance review. It shows up in disengagement, missed opportunities, and the gradual erosion of team effectiveness.
Chemistry vs. Credentials
When building engineering teams, it’s natural to focus on credentials. Degrees, certifications, years of experience, and familiarity with specific technologies are easy to evaluate and compare.
But credentials alone don’t determine how well a team will function.
Chemistry is about how people think and interact, especially under pressure. It’s reflected in how engineers handle disagreement, how willing they are to ask questions, and whether they approach problems with curiosity or defensiveness. It’s the difference between working side by side and truly working together.
In practice, two solid engineers who collaborate well will often outperform one exceptional engineer who operates in isolation. In complex systems work, integration skill frequently matters more than component expertise. The same principle applies to teams: the ability to connect ideas across boundaries often outweighs depth in any single area.
Why Poor Team Dynamics Hurt More Than Technical Gaps
One of the most important leadership lessons in engineering is that technical gaps are usually solvable. Teams can learn new tools. They can acquire domain knowledge. They can experiment, iterate, and improve.
Human gaps are harder.
Poor team dynamics create problems that compound over time. Misunderstood requirements go unchallenged. Assumptions remain implicit instead of examined. Issues that could have been addressed early surface late, when they are more expensive and more disruptive.
Most project delays are not caused by unsolvable technical challenges. They are caused by coordination failures, by people not sharing information, not aligning expectations, or not feeling comfortable raising concerns.
When team chemistry is weak, even small issues can cascade into systemic problems.
Lessons from Complex and Regulated Industries
In complex and regulated environments, such as aerospace, medical devices, and industrial systems, the importance of team chemistry becomes even more pronounced.
These industries are built around reliability. They emphasize redundancy, verification, validation, and strict process discipline. Yet behind every checklist and control is a human team interpreting data, making judgment calls, and responding to uncertainty.
When failures occur in these environments, they are rarely the result of a single bad engineer or a simple technical oversight. More often, they trace back to breakdowns in communication and coordination: a concern that wasn’t escalated, an assumption that wasn’t challenged, or a signal that was missed.
Strong team chemistry enables the behaviors these industries depend on most, open communication, shared ownership, and a willingness to surface problems early, before they become failures.
Designing for Chemistry
Strong team chemistry does not happen by accident. It is shaped by leadership decisions, incentives, and culture.
Leaders who prioritize collaboration over heroics, who value clear communication as much as technical depth, and who reward those who elevate others create teams that scale. They design teams intentionally, balancing experience, perspectives, and working styles rather than simply assembling the strongest individuals available.
They also recognize that team health is a leading indicator of long-term performance. Predictable delivery, knowledge sharing, and constructive disagreement are signs of a team that will succeed not just once, but repeatedly.
The Human System
Engineering organizations invest heavily in optimizing technical systems, architectures, tools, frameworks, and processes. We design interfaces carefully and validate performance rigorously.
But the most complex system we manage is the human one.
And like any system, its performance is not defined by its strongest component. It is defined by how well the parts work together.
In the end, the teams that consistently outperform are not the ones with the most brilliant individuals. They are the ones with the strongest chemistry.
