From Contributor to Tech Lead: 7 Things No One Told Me
From Contributor to Tech Lead: 7 Things No One Told Me
Becoming a tech lead isn’t just a promotion — it’s a role change. This post breaks down the real-world lessons no one talks about, from shifting priorities to leading without authority.
Oct 1, 2025
I used to think becoming a Tech Lead meant I’d just be writing more important code.
Instead, I found myself in a new reality where:
My calendar suddenly mattered more than my keyboard
I was the default person for “unblock this” requests
And half the job was protecting my team from the chaos above us
No one really prepares you for the weird middle ground that is the tech lead role. You’re not a manager, not a pure IC, not a PM — but you’re expected to operate in all three lanes.
Here are the 7 things I wish someone had told me before I made the leap.
You’ll Spend Less Time Coding — and That’s OK
The biggest mental shift? Letting go of being “the most productive engineer on the team.”
You’ll still write code, but it’s no longer your primary output. You’ll be:
Unblocking others
Reviewing high-risk PRs
Shaping technical direction
Translating product asks into executable work
It’s not about doing more — it’s about making sure the right things get done.
You’re Now a Shield
You will spend real time absorbing ambiguity, context switching across 3–4 threads, and catching incoming chaos before it hits the team.
Bad specs, unclear priorities, last-minute scope creep — your job is to clarify before it cascades into engineering churn.
Great leads don’t just build great systems — they build calm.
You’re Responsible for Outcomes, Not Just Code
Before, success was shipping a feature. Now? It’s whether the feature:
Solves the actual problem
Was delivered without burning out the team
Can be maintained by someone other than you
You go from “I shipped it” to “We shipped it, and it worked.”
You Have to Scope in Real Life, Not Just in Jira
As a tech lead, you become the person who gets asked, “Can we build this in 2 weeks?”
You’ll learn to:
Push back on unrealistic timelines
Negotiate trade-offs (MVP vs polished)
Surface hidden work early (infra, migrations, access)
You won’t always say “no.” But you’ll get really good at saying “yes, if…”
You’ll Make More Decisions with Less Certainty
No one hands you perfect information. Often, you’ll have 70% of the data and need to make a call anyway.
You’ll learn to:
Trust your instincts
Get fast feedback
And course-correct without shame
Leadership isn’t having all the answers. It’s knowing which question to ask next.
Influence > Authority
You won’t always have formal power. But you’ll still need to:
Get buy-in
Drive alignment
Change behavior
That means leaning on trust, clarity, and empathy — not hierarchy. The best tech leads I know don’t win arguments. They build consensus.
You’ll Have to Let Others Shine
This might be the hardest shift. You’ll have to:
Let someone else take the “fun” ticket
Delegate things you could do faster yourself
Celebrate wins you didn’t directly contribute to
Your job is no longer to be the star. It’s to make the team shine.
