“As a data professional who has set his career pathway more on the technical side,
guides like this are crucial for additional mandatory learning. Data engineering isn't
merely tables and SQL. Data engineers need to have an understanding of
infrastructure, DevOps and the cloud to develop and deploy solutions. I believe this
guide will aid data engineers in de-risking their careers“

“As someone without a background in tech whose career changed into DevOps, this
pathway has been fundamental in both securing my first entry-level role, and
upskilling to where I'm at today. There's a myriad of resources online but finding a
clear, well-written pathway has made the whole process much more efficient and
allowed me to invest my time more wisely, as well as identify areas where I can gain a
competitive edge in my work. Especially the more advanced topics like CI/CD,
monitoring and SRE. Massive thanks to Mohamed for this excellent guide and all his
hard work“

💰 How much do DevOps Engineers
earn? 💰
While not everyone is solely motivated by salary, job stability and long-term career
progression can be strong driving factors. In the midst of the pandemic, many people
experienced job scarcity, increased competition, and the realisation that holding a
degree alone might not be enough to stand out in the crowd. Discovering the field of
DevOps and its potential opened doors to a better livelihood for many individuals.
The attractive salaries associated with this field serve as an additional source of
motivation.
Now let's move on to the exciting part!
Disclaimer: As I am based in London, UK - the salaries I mention will be based on

this location. The US, the rest of Europe and other parts of the world will vary so do
your research.
Here are the approximate salary ranges for DevOps Engineers in the UK:
1. Entry-level/Junior DevOps Engineer:
Salary Range: £35,000 to £50,000 per year
2. Mid-level DevOps Engineer:
Salary Range: £50,000 to £80,000 per year
3. Senior DevOps Engineer:
Salary Range: £80,000 to £100,000+ per year
4. Principal Engineers/Engineering Managers
Salary Range: £120,000+
Please note that these figures are rough estimates and can fluctuate over time. I
recommend checking platforms like Glassdoor and consulting with recruiters who
specialize in the tech industry to get more accurate and up-to-date salary
information.
While salary is not the sole measure of success, it is an aspect worth considering in
your career journey. Remember, the salary figures mentioned here are intended to
provide a general idea and should not be considered definitive or current. Focus on
your passion, continuous learning, and honing your skills, and the financial rewards
will follow.
Now, let's delve into the upcoming chapters, where we will explore practical steps
and valuable insights to kick-start your career in DevOps!

💼 Preparing for your first role 💼
Note: I have recommended specific resources and products. Note that I am not
sponsored or paid to recommend rather they are recommendations based off my
personal experience and quality of the courses.
Once you have completed Levels 1 and 2, you are ready to showcase your skills and
apply for jobs. You are nearly at your goal now! This is the last hurdle between you
and a DevOps role!
📝
Prepare your CV
Crafting a well-designed CV is crucial, as it is often the first thing that recruiters or
hiring managers see. A well-prepared CV can significantly streamline the application
process. I recommend using a website called flowcv.io to create your CV. It saves you
time by providing pre-designed layouts and helps you create an impressive
presentation.
Your CV layout should include:
Your name and contact details
Links to your LinkedIn profile, GitHub repository, and other relevant social
media platforms
A concise profile summary
Professional experience
Skills acquired through this learning pathway, including relevant certifications
Showcase your projects and educational background, keeping it simple and
concise
Max 1 page
Hands-on projects (ideas)
📂
Working on hands-on projects is vital to reinforce your learning and
demonstrate your skills. As an interviewer and hiring manager myself, I can tell
you that a well-executed project on your CV or GitHub repository immediately
earns you extra brownie points.

Credits to the project creation to Abdurahman Abukar!
Large DevOps Project for the CV (AWS, Terraform, Git, Linux, CICD)
Create 2 modules in Terraform that can create a webapp that runs nginx (on
an EC2 instance) and a module for a VPC (add all required parts such as
NatGW, route tables and everything else). Using AWS. Using correct
folder/directory strategy. Make sure you can access the site after (figure out
how to do this)
Make sure the modules work and you can run on 3 different environments
like prod, dev and staging.
Create a CICD pipeline to run your Terraform workflow (ideally with
GitHub Actions) but you can use GitLab pipelines or even Jenkins if you
want.
Make sure you use env vars for any credentials. I don't want to see any
hardcoding of credentials.
Bonus:
Write Terratests for your modules (this is in Golang) or you can do unit tests
in Python. Whichever you like but I recommend Terratests as it's a well
known industry standard.
Createa a nice README markdown documenting all your work so that
another user can run it.
Put all your work in a GitHub repo and commit it there. Use what is
necessary like gitignore and pre commit configs. And anything else you
deem useful and secure for the project.
Note: You can use chatGPT but make sure you understand what you’re writing
and creating and can explain in an interview. I want to see your thinking and
how you go about it. So that if someone asks in an interview, you can explain.
Networking & Socials
🤝
Networking is a crucial aspect of building a successful career in DevOps. Engage
actively on platforms like LinkedIn, Twitter, or any other suitable platform of your
choice to share your knowledge and contribute to the community. Each platform

offers unique benefits, so choose the one that resonates with you the most.
Remember, throughout your life, you will always be interacting with fellow humans,
so developing networking skills is essential.
Your GitHub
🐙
Create a personal GitHub account and showcase all the projects you have worked on.
This allows you to manage your code effectively and demonstrate your skills to
potential employers. Feel free to explore my GitHub (https://github.com/moabukar)
as an example.
Job application
💼
Everyone has different experiences but what works consistently is having focussed
applications. Make sure your CV is reviewed by experienced Engineers or reach out
to our supporting communities (Dee engineers, Somalis in Tech, Deen Developers)
and we will happily do CV reviews for you. Once your CV is ready, try to get referrals
from the companies you are looking to join - these referrals help you to get
interviews. Once again, you must network for this to be possible. This is very
important!! Reach out to recruiters on LinkedIn. Message employees who are already
working in the companies you want to work for and get some insights.
One advice, expect many rejections as this will be your first role, this is normal. Keep
applying and be patient. This is the final hurdle. Keep pushing till you get that offer!
Interview prep
To prepare for interviews, I have created a tech interview question bank
(https://github.com/moabukar/tech-vault) that all engineers can benefit from. This
resource will help you familiarize yourself with common interview questions and
improve your problem-solving skills. If you can, try to get mock interviews done by
other senior engineers from the community. This will really boost your interview
skills and prepare you beforehand.
