In-house feel, nearshore
FastAPI Developers
FastAPI has become the default for new Python services in British teams, from product backends to the APIs in front of ML models. We embed senior FastAPI engineers as full-time colleagues on your hours, employed by us, so you get depth without a London backend salary.
- Async, typed services designed for production load
- Working your hours, in your standups
- Our employee, your team member, no contractor grey areas

Our Service
Backend depth, delivered as a service
We put matched candidates in front of you within seven working days and have your engineer embedded in about two weeks. You direct the work; we carry employment, payroll and retention. One monthly fee covers it all, with no placement charge and nothing to pay for interviewing.
- Interviewing within 7 working days, embedded in about two weeks
- One monthly fee, no recruitment or placement charges
- Rolling monthly contract with 30 days notice
Documented APIs as standard
Everything a modern Python backend needs
- Build scalable APIs with modular routing, validation, and OpenAPI-ready schemas.
- Python Async ProgrammingLeverage async I/O for performance across endpoints, tasks, and services.
- Database IntegrationConnect APIs to SQLAlchemy, PostgreSQL, Redis, and more for full CRUD capability.
- Security & AuthImplement OAuth, JWT, role-based access and secure endpoints with FastAPI’s tooling.
- Docker & DeploymentPackage services in containers and deploy across staging and prod easily.

Vetting
You see two people - not 200 CVs.
Engineers vet engineers
A senior engineer runs a live technical conversation on the candidate's real stack, not a recruiter working from a keyword list.
Live coding, not take-homes
Real problems solved in front of an assessor, with anti-cheating checks. You see how they actually work, not what they submitted overnight.
A full profile, not a CV
Every candidate arrives with a CV, interview summary, coding-test breakdown and rate in pounds. You decide on evidence.
Every tab is a stage a candidate has to clear. Six of them, all run by our own internal engineers at Cloud Employee, before you see a name.

"Walked me through an assistant that was quietly hallucinating refund policy, how he caught it in evals, and what he got wrong on the first fix. Hire-ready for a senior seat."

The framework is easy, the architecture is not
Any competent developer can stand up a FastAPI route; fewer can design the schema, auth and data boundaries that keep a service honest at scale, and that is what our CTO-led vetting tests with live pair programming. The result costs 50 to 75% less than a comparable British hire once national insurance, pension and recruitment fees are counted.
- Vetted on architecture and data design, not syntax recall
- Live pair programming with a senior engineer before you meet them
- 50 to 75% less than the all-in cost of a UK hire
Not just a developer

Got questions?
The questions CTOs and founders ask.
Yes. Most of our clients are in the UK, the US and Australia. Your developer works your hours, and a UK-based client success manager is your point of contact throughout.
Cloud Employee is the employer of record, so your developer is our full-time employee rather than a contractor you engage directly. We handle their payroll, benefits and HR in their own country.
Typically 50-75% less than a comparable UK hire once salary, employer costs and overheads are counted. Rates run from roughly £28 to £63 an hour ($35-80, depending on seniority), billed as one monthly fee with no placement charges.
Vetting is CTO-led and covers a technical assessment, a live pair programming session and cultural fit screening, all run by senior engineers rather than recruiters. You interview a shortlist of two matched candidates.
You are typically interviewing matched candidates within 7 working days of a requirements call, and developers are often embedded and pushing code within about two weeks.
There is a two-week money-back guarantee, and if you want to continue we replace the developer free of charge.
Your developer's working hours are aligned to yours, so stand-ups and pairing happen through the UK day, and we keep cover available outside standard hours for anything critical.
There are no placement fees and you pay nothing to interview. Vetting is run by our in-house CTO with peer review from senior engineers, and after the hire we stay responsible for HR, payroll and retention rather than disappearing once the invoice clears.
Yes, always. Your developer sits in your Slack, email and daily channels as a full member of your team, and can even list your company on their LinkedIn if you prefer.
Yes, clients are welcome at our offices, which are set up for exactly that. Hire four or more developers and we cover the flights and accommodation for a visit.
You are typically interviewing matched candidates within 7 working days of a requirements call, and developers are often embedded and pushing code within about two weeks. From there it is a rolling monthly contract with 30 days' notice, one monthly fee, and no placement charges. You can scale up or down as the work changes, and you pay nothing to interview.
