How long does it take to hire a senior developer?
Short answer: in tech, the median time between opening a role and an accepted offer is 48 days (SmartRecruiters, 2025). For a senior developer in France, add the notice period, which is often 3 months for managers and senior staff. From launch to first day, plan for 4 to 5 months if nothing gets in the way.
The timeline, step by step
Role brief: 1 week to clarify the need, the salary and the deal-breakers.
Sourcing and outreach: 2 to 3 weeks to identify and contact people who are already employed.
Interviews: 2 to 3 weeks if the process has 2 or 3 stages.
Offer and negotiation: about 1 week.
Notice period: 1 to 3 months in France depending on status and collective agreement. Under the Syntec agreement, it is 3 months for managers and senior staff.
Why these hires are still slow in 2026
According to Apec, developer job ads in France dropped by about 20% in 2025. You might think candidates are now easy to find. For senior profiles, they are not: the best ones are employed, do not read job ads, and only move for a project that really interests them. A job ad attracts many applications, but few that fit.
Five ways to save several weeks
A precise brief from day one: most delays come from a need that changes along the way.
A short process: 2 or 3 interviews, not 5.
Feedback within 48 hours: a senior candidate usually has several options in parallel.
Salary shared in the first conversation: it avoids losing three weeks with someone outside the budget.
Direct sourcing: go and find the profiles instead of waiting for them to apply.
With a dedicated sourcing mission
A Source To Match mission lasts one month, organised in 4 sprints: market mapping, outreach, qualification interviews and final shortlist. In practice, plan 3 to 6 weeks between kick-off and a signed offer, depending on how rare the profile is. The notice period then remains the longest step.
Frequently asked questions
Can a candidate's notice period be shortened?
Yes, if the current employer agrees. It is a negotiation between the employee and their employer, which works more often when a leaving date is proposed early and constructively.
Should you bring in a freelancer in the meantime?
It is a good option if the project cannot wait 4 to 5 months. The freelancer covers the hiring and notice period.
Is it the same timeline for a junior developer?
No. Juniors apply to job ads more and have shorter notice periods. The challenge is mostly screening applications.
