Frequently asked questions
How much notice should I give as an engineer?
Standard practice is two weeks, but if you are a lead engineer or sole maintainer of a critical system, offering three to four weeks can be highly appreciated to facilitate a proper knowledge transfer.
Should I mention the specific projects I am handing over in the letter?
You don't need to list every project in the formal letter itself. A broad statement about ensuring a smooth transition and documenting your work is sufficient. Save the detailed list for your transition plan document.
What if I am asked to leave immediately due to security policies?
In many tech companies, engineers with high-level access may be asked to stop working immediately upon resigning. If this happens, remain professional, comply with all security protocols, and ensure you have already backed up your personal files beforehand.
