Switching to a career in tech in 2026: how to choose your path (dev, data, UX, cyber...)
Aug 7, 2026
Tech is hiring. Your friend did a 6-month coding bootcamp, and now they're making €50k. Another one transitioned to UX design and absolutely loves it. You tell yourself, "maybe I should look into it too."
Except "tech" comprises 30 different professions. Choosing the wrong path = 6 months of training only to end up in a job you hate.
Here is how to choose wisely.
The real challenge: "tech" is a catch-all word
When you say "I want to work in tech," you could mean: - Developing apps (dev) - Analyzing data (data) - Securing systems (cyber) - Designing interfaces (UX/UI) - Managing tech projects (project manager, PM) - Helping companies adopt tech (consultant) - Managing servers (DevOps, sysadmin) - Designing products (product manager) - Marketing tech solutions (growth, product marketing)
Each of these professions requires very different skills, a very different daily routine, and a very different personality profile.
The wrong reflex: "I'll choose the path that pays the most"
A classic mistake.
The best salaries in tech go to those who love their job. Because they work 10 years in the field, become experts, and are highly sought after.
If you choose a tech job "just because it pays" and you hate it, you will: - Underperform - Remain a junior with mediocre salaries - Switch careers after 2 years
First, choose what suits you. The money will follow.
The 6 major tech paths (and who they are for)
1. Developer (web, mobile, back-end dev)
What you do: you write code that powers websites, apps, or systems.
Key skills: logic, problem-solving, autonomy, patience.
Who it is for: you like building things, you are patient when facing a problem, you love the satisfaction of "making something work."
Junior salary: €35-45k. Senior salary (5+ years): €55-80k (Paris) / €45-65k (provinces).
Training: bootcamp (Le Wagon, Ironhack, Wild Code School) for 3-6 months, or school (42, Epitech) for 3-5 years, or self-training (OpenClassrooms, FreeCodeCamp).
Quick test: try to follow 5-10 hours of a Python or JavaScript tutorial (free on YouTube). If you give up after 2 hours of frustration, this job is not for you.
2. Data Analyst / Data Scientist
What you do: you analyze data to help companies make decisions.
Key skills: numbers, curiosity, ability to tell stories with data.
Who it is for: you like numbers, you love understanding "why" something happens, you are curious.
Junior salary: €38-48k. Senior salary: €55-85k (sometimes more for data scientists).
Training: bootcamps (Le Wagon Data, DataScientest), Master's in data, self-training (Coursera, DataCamp).
Quick test: download a free dataset (Kaggle), run it in Excel or Google Sheets. Do you enjoy exploring the numbers? Good sign.
3. UX / UI Designer
What you do: you design the user experience and interface of websites/apps. You create mockups and test them with users.
Key skills: creativity, empathy, visual sense, user listening.
Who it is for: you are visual, you like understanding people, you have an aesthetic sense.
Junior salary: €32-42k. Senior salary: €50-70k.
Training: bootcamps (Ironhack UX, OpenClassrooms), design schools, self-training (Figma + free Design School).
Quick test: download Figma. Create a simple app mockup. If you find yourself in the flow for 2 hours without realizing it, that's a good sign.
4. Cybersecurity
What you do: you protect systems from attacks. You detect, prevent, and respond to threats.
Key skills: rigor, technical curiosity, constant vigilance, stress tolerance.
Who it is for: you like playing the "detective," you are rigorous, and you handle stress well.
Junior salary: €42-55k (often better paid than a junior dev). Senior salary: €70-100k.
Training: Master's in cyber, certifications (OSCP, CISSP), specialized bootcamps.
Note: the junior cybersecurity market is saturated, but profiles with 2-3 years of experience are highly sought after.
5. Product Manager (PM)
What you do: you decide what to build, for whom, and in what order. You bridge the gap between business, tech, and design.
Key skills: communication, prioritization, user empathy, a bit of tech, a bit of business.
Who it is for: you like coordinating, you are comfortable with ambiguity, you can talk to everyone.
Junior salary: €45-55k. Senior salary: €65-110k.
Training: dedicated training is rare, people often get here after dev, marketing, or consulting. PM bootcamps (Product Institute, Reforge) exist but are expensive.
Quick test: have you ever managed a complex project with 5+ stakeholders? Did you like it? Good sign.
6. DevOps / SRE / Cloud Engineer
What you do: you manage the infrastructure that runs apps. You automate deployments and monitor systems.
Key skills: highly technical, systemic thinking, stress tolerance (on-call shifts).
Who it is for: you like understanding "how things really work under the hood," you are patient, and you can handle being on-call.
Junior salary: €40-55k. Senior salary: €65-90k.
Training: often an evolution from dev or sysadmin, cloud certifications (AWS, Azure, GCP), specialized training.
The quiz to find your tech path
Answer honestly:
Q1: You prefer to...
A) Build (coding, designing, making)
B) Analyze (figures, data, patterns)
C) Coordinate (managing people, prioritizing)
D) Protect (security, robustness)
Q2: When faced with a problem, you...
A) Dive right into solving it (dev)
B) Analyze all variables before acting (data, cyber)
C) Bring the relevant people together (PM)
D) Optimize so that it never happens again (DevOps)
Q3: Are you more...
A) Solitary, deep focus
B) Social, energized by others
A mix
The solitary type → dev, data, cyber, DevOps The social type → PM, UX The mix → all of them, depending on the company
Q4: You prefer to...
Make mockups → UX
Write code → dev
Make numbers talk → data
Hunt for vulnerabilities → cyber
Decide what to build → PM
Optimize systems → DevOps
Q5: How much time are you willing to invest in training?
3-6 months → bootcamp dev, data, UX
6-12 months → cyber, more solid dev, intensive self-training
1-3 years → deep career transition, school, master's degree
The factor people forget: your personal profile
A 35-year-old profile who has worked for 10 years in HR won't have the same opportunities as a 24-year-old fresh out of bootcamp.
Professions where previous experience matters the most
PM: your business/professional experience is a real asset
UX: your empathy and understanding of the field help
Tech Consultant: same
Cyber: same, especially if you have experience in a regulated field (banking, healthcare)
Professions where previous experience matters less
Pure Dev: you are evaluated on your technical level, not your past
Data: same, your data skills are looked at above all else
If you are 30-45 years old, prioritize jobs where your experience counts. You will reach senior level faster.
Classic tech career transition mistakes
1. Choosing dev "because that's what everyone says to do" Dev is a highly specific job. If you don't like spending 4 hours debugging, don't do this job.
2. Doing a bootcamp without testing it first A bootcamp costs €6,000-15,000. Do 20-40 hours of free self-training first (OpenClassrooms, YouTube). Validate your actual interest.
3. Believing that a tech career transition = €80k salary from the start False. Big salaries come after 3-5 years. A junior earns €35-45k.
4. Choosing the shortest path, not the most suitable A 3-month bootcamp is great for front-end dev. Not for serious cyber or DevOps.
5. Ignoring the competition Every year, 10,000+ people switch careers to dev in France. Your differentiation comes from: your past experience, your soft skills, your portfolio, your network.
The method to test before you transition
Before investing €5,000-15,000 in a training program, test it out:
Step 1: 20 hours of free self-training (2 weeks)
Dev: Python on OpenClassrooms
Data: SQL on DataCamp
UX: Figma tutorials
Cyber: "Introduction to Cybersecurity" course on Cisco
PM: reading "Cracking the PM Interview"
Step 2: 3 coffee chats with pros in the field (2 weeks)
Contact 10 people on LinkedIn who work in the target job. 2-3 will agree to a coffee chat. Listen to their real daily life.
Step 3: mini personal project (2 weeks)
Do something concrete: - Dev: small personal website - Data: analyze a public dataset - UX: mockup of a fictional app
If you enjoy these 6 weeks of testing → go for the training. If you hate it → you've just saved €10k and 6 months of your life.

Conclusion
Tech = 30 different jobs. Choose based on who you are, not who pays the most. 6 major paths: dev (build), data (analyze), UX (design), cyber (protect), PM (coordinate), DevOps (optimize). Before paying €6-15k for training: 20h of free self-training + 3 coffee chats with pros + mini personal project = you validate your real interest. Salaries of €80k+ come after 3-5 years, not from the start. If you are 30+ with experience, prioritize jobs where your past counts: PM, UX, consultant, cyber.
