Astrology will not pick a job title for you, but it does describe the type of work you find fulfilling and the type of role others expect you to fill.
1. The Midheaven
Your MC describes the public role, the reputation, the kind of contribution. Read its sign and ruler.
2. The 6th house
The 6th house describes day-to-day work conditions: solo or team, structured or improvised, body-led or mind-led.
3. Your dominant element
A water-dominant chart wilts in pure spreadsheets. A fire-dominant chart wilts in slow committee work. The element is the energy you have to spend daily.
Putting it together
The right job sits where the MC, the 6th and the dominant element agree. Build your chart in the natal chart.
