Senior-only
Every engineer is senior. No mixed teams. No rotating juniors. No “we’ll get you someone better next sprint.”
Senior Extension · team extension
Send us your open role. You interview and choose.
We shortlist senior engineers who match your role — stack, level and how your team works. You interview them and choose who joins. They work inside your team: your Slack, your sprints, your codebase.

14-day fit guarantee
Not the right fit in 14 days? You don't pay for them.
You interviewed and chose the engineer — and you still get two weeks of real work to be sure. If it doesn't work, say so. Those days are free.
Days 1–14Real work, inside your team
Your Slack, your standups, your codebase. Not a trial task.
Any daySay “not the right fit”
In Slack, by email or on a call. No need to explain.
ThenNo invoice for those days
We bring a new candidate or close the engagement — your choice.
Written into every Senior Extension contract.
Send us your role
One role is enough to start.
A founder reads it and replies within one business day: whether we can staff it, the seniority we'd propose, and when you can meet the first candidates.
- Rates are agreed per role, on the first call — often below the cost of hiring the same seniority locally.
- Under your tech lead, our team lead, or a mixed team.
- Sending a role commits you to nothing.
What it is
Senior capacity, inside your team. Led by your lead — or ours.
Hired for your role
Send us your open role. We find and screen seniors for it — you interview them and choose. No bench, no filler seats.
Gemi Control Tower inside
Our seniors work inside Gemi Control Tower: pre-built scaffolding, AI code generation, 40+ ready modules. Deployed on day one.
Your lead, ours, or mixed
Our seniors join your team under your lead — or our team lead runs a team for you, or leads a mixed team of your engineers and ours. Either way, the lead reports to you. Direct access, no account-manager layer.

When this fits
Staff augmentation gave you seats. You needed engineers.
Hire us when
- you have an open role and want seniors you interview and choose yourself
- you have strong leadership and need seniors inside the team, not seats on the side
- something needs to ship and the team is stretched
- one decision-maker can greenlight this week
Don't hire us if
- you want juniors to fill seats
- you need warm bodies, not working software
- nobody can say “yes” without a committee

Senior-only. You interview and choose. 14-day fit guarantee: if the match isn’t right, you don’t pay for those days.
