My first step as technical project manager would be to investigate the root cause of the problem. This will involve interviewing employees who have resigned to get their honest reviews and opinions about the company and why they are resigning. Some employees may resign as a result of finding better opportunities elsewhere. Some of the reasons that lead employees to resign are unnecessary stress and pressure which may come as a result of strict rules and over bureaucracies. I will handle such issues by allowing employees and team members to provide their opinions before making a decision. Also aligning juniors with the seniors helps to minimize technical pressures on the junior employees. The seniors will act as mentors providing first hand mentorship assistance and guidance. Allowing flexibility such as flexible working hours and other times, working from home. Developing a reward system in the organization by recognizing and rewarding employees for their good work as well as creating compensation packages. Giving employees the opportunities to further their skills and knowledge by allowing room for regular training highly motivates and creates a good working environment in an organization.   My backfilling procedure involves promoting the talented junior employees to senior positions, training employees to be ready to take those senior positions whenever an opportunity arises and carrying out transparent and skill oriented interviews to pick individuals with the right skills. Also, allowing the current employees to provide referrals for positions that require filling.
