Why I Left My Stable Job to Pursue a Developer Career

Five years into my role at Saint-Gobain, I handed in my resignation to chase a career in tech. Here’s why I traded security for code—and how I’m navigating this radical pivot.


The Catalyst: When Comfort Became a Cage

Why I Walked Away

  • No Growth Trajectory: Limited upward mobility despite strong performance.
  • Misaligned Purpose: Felt disconnected from the company’s core mission.
  • Family Influence: Two brothers in tech showed me the possibilities of remote work and creative problem-solving.

"I realized staying was riskier than leaving. Every day I didn’t code felt like a step backward."
— Julien Thomas

The Final Push

After a rejected internal transfer request, I activated France’s Professional Transition Project (PTP) to fund my retraining. The bureaucracy of corporate life cemented my decision:
🔸 40+ hrs/week in meetings
🔸 Zero autonomy over projects
🔸 No tangible impact metrics


Building the Bridge: Skills, Research, and Sacrifices

Transferable Assets I Bring

| Technical Skills | Soft Skills | |------------------|-------------| | PC Assembly/Repair | Client Needs Analysis | | Basic Web Dev (HTML/CSS) | Project Management | | Tech Troubleshooting | Public Speaking |

Reality Checks I Faced

  • Salary Drop: From €4,055/month to junior dev rates (~€35k/year)
  • Lifestyle Shifts: Sedentary work vs. previous on-site role
  • Learning Curve: 9-week Ironhack bootcamp requires 60+ hr weeks

My 3-Point Preparation Strategy

  1. Network Mining: 6 coffee chats with developers (including 2 freelancers)
  2. Portfolio Development: Built 4 demo projects (see GitHub)
  3. Financial Buffer: Saved 6 months’ expenses + Transition Pro’s 90% salary coverage
