Work as a Security Engineer on real systems
Projects where the offence is yours: which system gets tested, what gets monitored and which report gets written. Shakers connects you with teams waiting for an incident to take security seriously.
What gets read about cybersecurity is either glossaries of terms or certification syllabi. Neither tells you how to start protecting a real company's systems project by project, report after report. Here is that.
- Higher-paying projects
- More continuity between projects
- Greater recognition for your experience

Amelia
AI Agent Developer
“I have been building AI agents for years. Thanks to Shakers I stopped chasing clients and started genuinely choosing which projects I wanted to work on. I work with some of the best companies in Europe, at my own rate, and I focus on what I am good at and what I love: building.”

Luz
Backend Developer & Data Engineer
“Shakers adds a lot of value because it connects you with sharper projects, already filtered and better defined. It saves you a big part of the upfront work of understanding the client, quoting and weighing up whether it is worth it, and that means that as a contractor you can go far more directly to the opportunities that genuinely fit you.”

Rubén
Software Developer
“Life as a contractor has a lot going on and it is not always easy. We like to focus on what we are good at, but you also have to manage clients, invoicing and go looking for work. For me, Shakers has been key because it does that prospecting for me, it gives the client confidence from the very first moment, and it lets us be part of a community with real enthusiasm.”

AI Developer
“Shakers was key to getting my company off the ground: it gave me the flexibility to keep contracting while I built my next chapter. Without Shakers, I would have had to raise funding or push the project back.”

Toño

“With Shakers I have landed recurring projects that give me peace of mind and room to grow professionally. It is not just about reaching quality clients: it is feeling that you have a network behind you, one that connects you with real opportunities and helps you move forward as a freelancer.”
Join ShakersThe decisions a Security Engineer owns every week
A Security Engineer protects systems with offence and defence: penetration testing to find the vulnerability before the attacker, SIEM and XDR to detect in real time, and sector compliance. Their most visible craft, the pentester, thinks like the attacker to close the path; their real job is that the attack, when it comes, finds nothing open.
You decide which system gets tested first and with what method, which alert deserves a threshold and which is noise, and which fix is demanded before deploying again. You also decide what does not get done: a pentest without written permission does not exist. The systems belong to the company; that nobody breaks in, also yours.

What a Security Engineer delivers at Shakers
The brief arrives with the reason
Shakers is hiring infrastructure: the project arrives with the audit a client demands or the certification to pass, not with a list of technologies.
Reproducible reports
You deliver every finding with its exploitation path and its fix, in the format board and auditor understand without translation.
What happens when you detect
You set each alert's threshold, the escalation and response times. Detection without a response plan is expensive noise.
Real systems protected
Having pentested with permission on company systems and being able to tell the most uncomfortable finding you signed and how it was fixed.
Test or monitor
Choosing by real risk, not tool catalogue. Sometimes the honest answer is patch three things and stop, and defending it.
Where your brief ends
You protect the systems; you don't build or operate them. If the problem is pipeline or availability, you say so at kickoff.
Frequently asked questions
Any other questions? Write to us and we will reply.
What should you learn to work in cybersecurity?
The offensive method first: OWASP and pentesting practice in the lab. Then defence (SIEM, XDR) and sector compliance. Shakers certification looks at real reports.
Which tools do you use daily?
Pentesting tools (Burp, Nmap, Metasploit) for offence, the client's SIEM platform for defence and Python as glue. Certifications (OSCPP, CISSP) open doors.
Are pentester and ethical hacker the same?
Yes: two names for whoever attacks systems with permission to find the gap before the one without it. The Security Engineer widens that craft with defence and compliance.
How much do you earn as a freelance Security Engineer?
You invoice per project and scope sets the band: which systems the test covers and what monitoring remains. You agree the budget before accepting.
Is cybersecurity work something you can do remotely?
Almost everything: systems live in the cloud and tests are launched remotely. Only the odd physical audit asks for presence.
How do you join Shakers as a Security Engineer?
You create your profile, pass the certification process and enter the collective: only 4 percent make it. Then you choose your security projects.
The daily shape of the craft
The previous client's report nobody fixed, the alert that fires at 5 p.m. on a Friday and the auditor arriving next month. Fewer certificates accumulated, more systems left closed.
The craft with demand of its own
1,310 active tech job ads in Spain mention cybersecurity and pentester gathers 2,900 monthly searches, according to Shakers' market analysis (n=30,508, September 2026). The market asks for the craft by its name.
How people get here
Three frequent doors: the developer obsessed with breaking what they built, the sysadmin tired of patching, and the lab autodidact looking for their first real client.
What this role is not
Not the antivirus admin nor the paperwork signer. If the problem is the pipeline, the role is DevOps; availability, SRE. Here, you protect.
The roles a security project crosses
Four roles from the collective cross your path while you protect systems, from the one deploying to the one sustaining the platform.
DevOps Engineer
DevSecOps is built on their pipeline: the security of the software's path is worked shoulder to shoulder with them.
Site Reliability Engineer
Incident response coordinates with whoever sustains the platform: availability and security are the same small hours.
AWS DevOps Engineer
The security of the Amazon account (IAM, configuration) is audited alongside whoever builds and runs it daily.
Backend Developer
OWASP gets fixed in code: every application vulnerability is closed four-handed with whoever wrote it.
Boundaries between these roles are agreed per project: the job title doesn't set them.
