Secondary Turnover Risk

Why This Role Costs So Much
Senior Software Engineers are among the hardest roles to fill, with an average time-to-fill of 62 days in tech. Every day this role sits open, your team absorbs extra sprint work, your product roadmap slips, and the remaining engineers inch closer to burnout. The cascade effect on a 3-person team covering a senior IC is significant — and often invisible until someone quits.
- Engineering velocity typically drops 15–25% per missing senior IC on a small team
- Technical debt accumulates faster when senior review capacity is reduced
- Prolonged vacancies signal instability to candidates actively interviewing at competitors
- Ramp period of 120 days means full productivity isn't restored until well after hire
