Projects where the open engine is yours: which query gets tuned, which window gets used and who answers when the instance hesitates.
The trade reads in two places: the career-guidance card and the job ad asking for weekly on-call shifts without saying so. Neither tells you how to run a real company's critical database project by project. Here is that.

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.”

“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.”

Join ShakersA PostgreSQL DBA administers the open-source engine in production: tuning performance with execution plans and indexing, scheduling backup and recovery, configuring replication and high availability, and deciding schema migration windows.
They are the specialist of one engine under the database administration umbrella: PostgreSQL only here. The demand is embedded in skills: PostgreSQL appears in 1,593 live UK tech vacancies, 2.3x more than MongoDB.
You decide what gets backed up and how often, which index gets touched and in which window, which permission is granted and which withdrawn. You also decide what the database refuses: a deployment without a rollback plan doesn't go in. The engine belongs to the client; the policy that keeps it alive is yours.

Shakers is hiring infrastructure: the project arrives with the instances and their criticality, not a list of technologies.
You deliver the backup plan with tested restores, active monitoring and the why of every maintenance window.
You set the on-call protocol, what happens when an instance stops answering and who answers for the data while it recovers.
Having run engines in production and being able to tell an outage story: what failed, what you did and what changed so it never repeated.
Recognising when the brief belongs to your engine and when it asks for a specialist: PostgreSQL and MongoDB have their own page, and saying so.
You run the engine; you don't rewrite the application or the infrastructure. If the project asks for development, you say so at kickoff.
Any other questions? Write to us and we will reply.
The execution plan nobody read, the vacuum postponed for a quarter and the replication that exists but nobody tested. The trade is learned holding real engines, not manuals.
The real conversation in English isn't the engine but the service: leaving Oracle, ongoing support and post-migration aftercare. PostgreSQL appears in 1,593 live UK tech vacancies, according to Shakers' market analysis (n=39,811, September 2026), embedded in skills.
General database administration exists as an umbrella, and your certification is per engine: every delivery delimits what you ran and how deep. The boundary is declared in your profile.
Friday's deployment, the on-call shift the day the instance doesn't answer and the backup that restores without drama: the bar is the administrator's calm.
Four roles from the collective cross your path on a database project, from the engine specialist to the one automating the cloud.
The umbrella of the trade: when your brief touches SQL Server, Oracle or MySQL alongside the open engine, that's the general page.
The collective's NoSQL specialist: when data doesn't fit tables, the page administering MongoDB and its scale.
Their applications write to your engine: schemas and queries your administration sustains, with their deployment windows.
The infrastructure the engine runs on: snapshots, networks and the cloud cost carrying the instance.
The boundaries between these roles are agreed on each project: the title does not set them.
