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 resume, interview summary, coding-test breakdown and rate. 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."

Got questions?
The questions CTOs and founders ask.
We align our working hours with your time zone, and ensure overlap for real-time collaboration. We also have team members available for critical support outside standard hours.
Entirely different. We take no placement fees, and you pay nothing to interview candidates; you only pay if you hire. Vetting is technical and led by our in-house CTO, with peer reviews from our senior engineers to avoid mishires. And we do not stop after recruitment. We work with you month on month as a partner, you have a dedicated account manager and CTO behind you, and if a developer does not work out we find a replacement with no re-hire fee. We are invested in the long term, and we act like it.
No - you can hire just one employee and receive the same excellent level of service.
You feed this back to your dedicated account manager, who will then work with you to find solutions. We have a robust HR team physically on-the-ground in our Philippines and Latin America offices, who work with our learning and development. Sometimes peer training with our other developers, or a conversation with our CTO, quickly improves any issues. If not, we find you a new hire, free of charge.
Yes absolutely. Developers plug directly into your day-to-day communication channels - company email, Slack channels, Discord, etc. Your developer is fully integrated into your team, even down to updating their LinkedIn with your company as their employer if you would prefer. In fact, if you hire more than 4 developers, we will also contribute $3,000 toward a trip for your developer to visit you, or for you to visit our beautiful offices in Manila and/or Latin America to meet and work with your developers in person once per year.
We recently scaled a full technical team of 28 developers and technical experts for one client in a single month. If you provide us all of the information we need, we can move very quickly.
We can hire project managers specifically for your project. We also advise you on the level of seniority and team mix required for your project and wider company needs, ensuring you have the right people to self-manage.
Expect to talk through your needs and for us to offer you support and advice. From there, if we're a good fit, we set you up with a call with our CTO and your account manager to provide feedback and/or develop job descriptions alongside you.
Entirely. Forget one-off jobs, security risks and project to project work. Read more here.
We encourage clients to visit our offices to meet and spend time working with their Cloud Employee team. We've made sure that our offices are well-equipped and always welcoming to our clients. In fact, if you hire 4 or more Cloud Employees, we will cover your flights and accommodation to visit our offices and work with your team. This is up to $3,000 worth of value.
