How engineering managers and leaders make architectural decisions that balance impact, cost, and speed.

As an Engineering Manager, you are no longer just thinking about systems — you are thinking about outcomes, people, and constraints.
You may not be writing every line of code or designing every service boundary, but your influence on system design is still significant.
The challenge is not whether engineering managers should be involved in system design — it’s how.
This post explores how engineering leaders can approach system design pragmatically:
balancing technical quality with ROI, enabling teams without abdicating responsibility, and making architectural decisions that actually move the business forward.
Although this is written from an engineering manager’s perspective, the ideas here apply equally to:
Even when you are not the one drawing the final diagrams, your decisions shape:
System design at this level is less about choosing technologies and more about shaping decision-making.
When I was an architect, my goal was to explore all reasonable design options.
I wanted to understand the full solution space — including designs with all the bells and whistles.
As an engineering manager, my lens changed.
I still care about good architecture — but now I care more about:
As an IC or architect, you want to build beautiful and effective systems.
As an engineering manager, you want systems that are good enough, shippable, and aligned with business reality.
Perfect systems that ship late rarely outperform pragmatic systems that ship early and evolve.
One of the most important shifts for engineering leaders is realizing that your job is not to provide all the answers.
Your job is to:
In design discussions, I often push on questions like:
Clarity accelerates decisions. Ambiguity slows everything down.
Whether architects report to you or operate as peers, the collaboration model matters.
I usually start by asking for a high-level design exploration, intentionally framed without constraints:
If resources were infinite, how would you design this system? What options would you consider?
This approach matters because:
Once I understand the landscape, we narrow down to one or two viable paths based on constraints like cost, risk, and timelines.
From there, designs become more detailed and concrete.
I don’t use rigid scoring models, but I do pressure-test designs across a few consistent dimensions:
This isn’t about finding the “best” design — it’s about making trade-offs explicit.
Buy-in matters because teams build what they believe in.
But buy-in does not require consensus.
Large architectural discussions with 15–20 people almost always fail:
Instead:
As an engineering manager, it’s your responsibility to:
Once the discussion is done, you must be sold on the design — because you will need to sell it to product, leadership, and the broader team.
Sometimes the engineering manager is the product owner.
Sometimes you are working closely with one.
In both cases, architectural decisions should start with a clear understanding of:
This framing allows you to:
Architecture disconnected from product reality almost always leads to wasted effort.
Two things I always look for in designs:
If these are not included in estimates, they rarely get done properly.
If you can’t measure what you’ve built, you can’t improve it.
If you can’t change it safely, it will slow you down over time — no matter how elegant it looks.
Operational excellence is not optional.
Microservices, micro-frontends, and distributed architectures can be powerful — and also incredibly costly.
In some cases, breaking systems apart improves velocity.
In others, it creates so many moving pieces that teams eventually move back to simpler architectures.
Design for the next 3–5 years, not the next 10.
Account for extensibility, but don’t chase it at the expense of simplicity.
Most systems will be rewritten or significantly reworked anyway.
Your goal is to delay pain, not eliminate change.
Over time, I’ve seen the same pitfalls repeat themselves:
Optimizing for extreme scale too early creates complexity debt that slows delivery today.
Healthy discussion matters. Endless debate does not.
Beautiful systems don’t automatically deliver business value.
If you can’t see your system, you can’t run it effectively.
Leadership means making imperfect calls with incomplete information.
Good enough systems that ship and evolve consistently outperform perfect systems that never leave the whiteboard.
System design at the leadership level is not about control — it’s about leverage.
Your influence comes from:
Architecture is not just a technical exercise.
It’s a leadership one.
