Tech Onboarding: The First 90 Days to Retain Your Hires

Recruiting tech talent is a major investment. But without structured onboarding, that investment is at risk: 22% of new hires leave their company within the first 45 days (source: Archie). Conversely, a solid onboarding process increases new employee retention by 82% (source: Zavvy). Here's how to structure the first 90 days to transform a hire into a high-performing and engaged team member.

Why Tech Onboarding Is Critical

The technology sector presents specific integration challenges:

• Technical complexity: existing codebases, internal architectures, and proprietary tools require significant learning time
• Talent scarcity: with over 150,000 job vacancies in Quebec, losing a tech hire due to poor onboarding is doubly costly
• Replacement cost: between 50% and 200% of annual salary to replace a tech employee
• Productivity: in the tech sector, the average time to reach full productivity is 60 to 90 days (source: Synoptim)

Employees who have an excellent experience during their first 90 days are ten times more likely to stay long-term with the company (source: Bureau des Talents).

The 30-60-90 Day Plan

Days 1-30: Discovery and Acclimatization

Goal: The hire understands the company, team, and tools.

• Day 1: personalized welcome, team introductions, configured workstation (nothing worse than arriving and waiting for your laptop)
• Week 1: internal tools training, repository access, architecture documentation, first buddy assigned
• Weeks 2-4: first simple tickets, participation in standups and code reviews, one-on-one meetings with each team member

Deliverables: first merged commit, global understanding of the product and architecture.

Days 31-60: Skill Building

Goal: The hire contributes autonomously on tasks of increasing complexity.

• Taking on medium-complexity tickets
• Active participation in architecture discussions
• First responsibility for a small project or feature
• Formal mid-point check-in with the manager: bidirectional feedback

Deliverables: feature delivered to production, identification of improvement areas.

Days 61-90: Autonomy and Integration

Goal: The hire is a full-fledged team member.

• Taking on complete projects
• Contributing to other members' code reviews
• Participating in team process improvements
• End-of-probation review: goals achieved, development plan

Fatal Onboarding Mistakes

• The "sink or swim": leaving the hire to figure things out alone is the leading cause of early departures
• Information overload: explaining everything on day one is counterproductive. Space out the learning
• Lack of feedback: waiting 3 months to give feedback is too late. Weekly check-ins during the first 30 days are essential
• Ignoring the social dimension: a developer who doesn't know their colleagues won't attach to the company

Tech Onboarding Checklist

Before day 1:

• Laptop configured, email access, Slack, VPN, Git repositories
• Designated buddy (ideally a senior developer on the team)
• 90-day plan drafted and shared
• Team notified of the new arrival

Good onboarding isn't a luxury: it's an investment that pays for itself within the first quarter through retention and productivity. At VALO, we support our clients beyond placement: we advise them on integration to maximize the success of each recruitment.
