Career transition
VoIP Engineer → AI Security Engineer
Not generic reskilling advice, but an analysis of the distance between two specific occupations: tasks, skills, pace, money and risk.
01 · Starting distance
Transition realism index
Five factors answer a more useful question than “will it work?”: where the route is naturally strong and where proof is needed.
This is a realistic route. The strongest support is Market opportunity (94%), while the main constraint is Entry accessibility (68%). The index estimates the distance between roles, not your ability.

Three transition scenarios
The same route affects work, money and fatigue differently. A duration without weekly effort says very little.

Portfolio project
One project cannot replace experience, but it gives an employer something concrete to discuss and shows you can finish real work.
36 hours
Applied case: VoIP Engineer → AI Security Engineer transition case
Take a real but anonymized situation from your current field and solve it as a AI Security Engineer would. The central project task is collecting and transferring routine data.
Your advantage is domain context from VoIP Engineer. Make it visible: show which beginner mistakes it helps you avoid.
What the project folder should contain
- A working output an interviewer can open, test and discuss
- A concise decision memo covering inputs, constraints and two rejected alternatives
- A result check using measurable criteria plus one failed approach and what changed
- A public 5–7-screen case study with all confidential data removed
What makes the project strong
- visible use of aI-system evaluation
- a real-world problem rather than a tutorial exercise
- a measurable outcome and explicit limitations
- enough depth to support technical interview questions

09 · An honest check
What you may not like
A good career choice is more than a list of benefits. Before studying, check whether you can live with the target role’s daily reality.
Less certainty than it appears
Many decisions in the target role are made with incomplete information, and quality is not visible immediately.
The daily rhythm will change
The target role contains substantially more working with data and ambiguous conclusions. That can be tiring even when the occupation sounds appealing in theory.
Entry pay may dip
Modeled average pay in the target occupation is lower. A financial buffer or an internal project may help avoid losing seniority.
