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.

  • Overview
  • CV
  • Tech interview
  • Coding test
  • Psychometric
  • Soft skills

Scored by people. We use AI to cross-check our own consistency - never to decide who reaches your shortlist.

Why Cloud Employee?

Vetted for judgement, not just clicks

No-code has made building cheap, which makes deciding what to build the expensive part. Our CTO-led vetting pairs every candidate with a senior engineer on a live build and screens for the data modelling and workflow discipline that keeps a Bubble app maintainable, at 50 to 75% below the all-in cost of a comparable British hire.

  • CTO-led vetting with live pair building, not a CV sift
  • 50 to 75% below the all-in cost of a UK hire
  • Two-week money-back guarantee and free replacement

Somewhere between 50 and 75% less than a comparable British hire when salary, employer national insurance, pension, recruitment fees and overheads are all included. We hire UK-based Bubble developers where that is what a client wants. More often the best value sits in Eastern Europe, the Philippines or Latin America, where the standard matches Britain at a much lower cost, and Eastern Europe is only an hour ahead of London. The point of the model is the strongest quality-to-cost ratio we can find, real capability at a sustainable price.

Bubble is a visual development platform for building full web applications without writing traditional code, covering the database, the logic and the interface in one place. Teams choose it for speed; a founder can take an idea to a working product in weeks, then iterate in front of real users without a deployment pipeline. The trade-offs are real though. You are renting Bubble's infrastructure, so you accept its pricing model, its performance ceilings and a degree of lock-in that makes later migration a rebuild rather than a port.

Look for data modelling, privacy-rule discipline and architectural judgement before any amount of workflow-building speed. AI has made the mechanical part of Bubble cheaper still; assistants can sketch workflows and page structures quickly, so the differentiator is the developer who designs a schema that survives growth, sets privacy rules that do not leak data through the API, and knows the platform's performance ceilings well enough to design around them. You also want honest fluency at the edges, using the API Connector well and dropping into custom JavaScript through plugins when the platform runs out.

Assess them on live work, not talk; ask for applications they built that are still running, and have them walk you through the data model and privacy rules. A short pairing session in the editor tells you more than any portfolio, so set a small task and watch how they structure it. Good questions include how they would spot and fix a slow page, when they would move logic to a backend workflow, and what would make them advise against Bubble entirely.

Demand is real and growing, driven by startups validating ideas and operations teams replacing overloaded spreadsheets with proper internal tools. Whether it is worth building on depends on what you are building. Bubble rewards products whose main risk is whether anyone wants them; you can test, learn and change direction faster than any conventional stack allows. It punishes products that need heavy computation, fine-grained performance tuning or portability, because leaving means rebuilding.

Yes, and on a platform like Bubble we treat skilled AI use as part of the craft rather than a shortcut to police. Our vetting specifically assesses whether a candidate uses AI tooling well, planning logic with it, generating custom code snippets for plugins, and then checking the result against the app's data model rather than trusting it blind. Soundness in Bubble is less about syntax, which barely exists, and more about whether workflows are efficient, privacy rules are watertight and the schema holds up.

Vetting is CTO-led rather than recruiter-driven, so the people judging a Bubble candidate understand what a well-built application actually looks like. Candidates go through a technical assessment, a live pairing session with a senior engineer working through a real build, a cultural fit screen and a psychometric assessment we built specifically for software engineers. For Bubble we care about evidence of shipped applications, sound data modelling and honest awareness of the platform's limits, not certificates.

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.

There is a two-week money-back guarantee, and if you want to continue we replace the developer free of charge. In practice this rarely comes up, because you interview a shortlist of two candidates who have already passed a CTO-led technical assessment and a live pair programming session, so the fit question is largely settled before anyone starts.
