Build your career as a Tech Lead
Projects where the technical decision is the engagement: which architecture holds the system, which code passes review and how the team that writes it grows. Companies that already build and need that judgement, not a course to complete.
Tech lead employment in Spain is full-time senior work, with Java and Python up front, and the conversation about the step up is dominated by guides: how to become one, what the role does, what it pays. The by-project way out barely had a door.
This is not another transition guide: it is what gets decided on a real engagement, what you must prove and where your rung ends.
- 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.”

“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 Tech Lead signs off every week
A Tech Lead is the senior who keeps writing code and decides a team's day-to-day technique: architecture, code standards, reviews, technical debt and mentoring. Working by project, they carry that judgement from engagement to engagement, with no people management.
Their boundary: the lead developer coordinates code without the architecture mandate; the engineering manager grows people and team; the Fractional CTO, intermittent executive direction. The Tech Lead is the rung that decides inside the team.
You decide whether the architecture holds what comes, what enters the code standard and what each merge reviews. You prioritise debt against delivery, pick stack with the team and pass judgement on in 1:1s and pairing. You also stop what should not run: a one-way migration is halted with an argument. The plan is the business's; the technique is yours.

Which decision you deliver as a Tech Lead at Shakers
The engagement arrives with a team
The company that already builds and needs judgement: system, team and technical debt on the table. A decision problem, not a list of tools.
Architecture that holds
The stack, the limits of the system and the pattern that repeats: documented decisions the team can defend without you in the room.
Code with criteria
Code standard, code review and mentoring: every merge leaves the team writing better than the last one.
Counted decisions, not courses
Having decided with real consequences and knowing how to tell it: which architecture you defended, which debt you paid, what the team learned.
Leading is also braking
Choosing between the migration product asks for and the risk it cannot hold. Sometimes not doing it wins, and defending that with evidence is the rung.
Where your engagement ends
You decide the technique of the team; the people belong to the engineering manager and the strategy to the CTO. If the engagement crosses, their row enters.
Frequently asked questions
Any other questions? Write to us and we will reply.
What does a Tech Lead do by project?
They make the day-to-day technical decision of a team by engagement: architecture, standards, reviews and mentoring. One system, one period and a standard that stays.
How do I move from senior to contract Tech Lead?
By deciding in public: which architecture you defended, which review taught, which debt you paid. The frequent door is senior employment; the step up gets certified on real cases, not studied.
How much to charge as a contract Tech Lead?
The mechanism marks it: seniority, team size, stack and billing by days or by project. Public references do not agree with each other; your budget closes per engagement.
Tech Lead or Engineering Manager?
The Tech Lead makes the architecture and code decisions; the engineering manager grows the people and keeps the team working. If deciding without stopping coding is you, this is your rung.
Can a senior Tech Lead work as a Fractional CTO?
Many end up there: the person bridges upwards, but they are two search doors. Today you direct the day-to-day technique of a team; the other rung has a row of its own.
Am I a developer, lead developer or manager?
If you decide architecture and reviews and keep coding, you are a tech lead; if you only coordinate, lead developer; if you manage people, manager. The market crosses the names; the craft is one.
The daily shape of the rung
The standard nobody wrote down, the review that slips and the migration that never starts. Less guide, more decisions while shipping: which pattern repeats, which debt gets paid, which spike decides the next step.
How the market names you
"Líder técnico" is the Spanish form of the rung; technical lead and tech leader are the same search. Lead developer is the neighbour below: it coordinates code without the architecture mandate.
From senior employment to engagements
475 active job ads in Spain mention tech lead, with Java and Python up front (Shakers market analysis, n=31,957, September 2026). Employment is full-time company work; the by-project route is the one this page opens.
How far your rung climbs
Many senior tech leads end up as Fractional CTOs in SMEs: the person bridges, the search does not. Today your engagement is the technique of the team.
The team around your decision
A technical decision does not travel alone: whoever writes the code, ships it or measures its quality crosses your engagement.
Fractional CTO
The next rung: intermittent executive direction for companies without technical leadership. Many senior tech leads end up there; their row opens that door.
Backend Developer
Half the team you lead: REST APIs, services and data in Java or Python. When the engagement asks for hands besides judgement, their row builds.
Full Stack Developer
The end-to-end generalist: frontend and backend under the standard you set. In small teams, the developer who decides most with you.
DevOps Engineer
Whoever turns your decision into delivery: CI/CD, reproducible environments and observability. A standard that never reaches production does not exist.
QA Engineer
The other face of the standard: automated testing and quality that hold the speed. Without QA, the technical debt you prioritise never gets measured.
The boundaries of this ladder get agreed per project: tech lead, manager and CTO are rungs, not fixed titles.
