PRICING MODEL
Managed Staffing.
Managed Staffing is open to every role we place. We find the person, handle payments and compliance, and stay involved after the hire with check-ins, visibility, and escalation when something is off. You get the person. We keep the machine running. For roles that create demand, outbound SDRs, BDRs, demand generation and full-cycle AEs, Managed Staffing runs on a six-month minimum term.
Pay
One all-in monthly rate
Per person. That is the number, and there is nothing added to it.

Direct Hire.
Direct Hire is open to every role we place. We find the person, vet them, and hand them over. You employ them, you manage them, you own the relationship from day one. Roles that create demand usually land here, because live call feedback and daily coaching work best coming straight from your sales leader, and there is no minimum term.
Pay
20% to 30%
Of first-year base salary. One time, quoted per role, paid when they accept.
In the fee
- Sourcing from the CloudTask staffing and recruiting company
- Screening and vetting
- Shortlist of matched candidates
- Interview coordination
- Offer support
- 6-month replacement guarantee. One replacement, same job description.

Testimonials
Trusted by teams that hire with us
-
LATAM has been a gold mine for talent. Our CloudTask hires understand our company culture and mission, and they connect with our customers in a way that drives high NPS and CX scores.
David Barrett CEO, Expensify -
At first we were an SF-based team only. Then I met Amir Reiter back in 2018. After visiting Medellín, I knew LATAM would be key to our growth and success.
Tim Zheng CEO, Apollo.io -
After meeting my CX and CS team in Medellín, we immediately loved the culture and the work ethic. As a European-HQ company, we found LATAM to be perfect to service our American clients.

SKILLS
Top skills to look for in a Kotlin developer
Kotlin that reads like Java with fewer semicolons misses the point. These are the skills that show someone uses the language to prevent bugs, not just to shorten code.
-
Null safety taken seriously
Models what can be missing in the types, and avoids the double-bang operator that brings back the crashes Kotlin was meant to remove.
-
Coroutines and structured concurrency
Launches work in the right scope, cancels it when the screen or request ends and handles errors without leaking jobs.
-
Types that model the domain
Uses data classes, sealed types and exhaustive when expressions so impossible states cannot be represented.
-
Clean Java interop
Works in mixed Java and Kotlin codebases and knows how nullability and annotations behave across the boundary.
-
Android or backend depth
Has real depth on the side you need, Jetpack on Android or Spring and Ktor on the server, not a tutorial on each.
-
Gradle under control
Keeps build scripts, modules and dependencies readable, so the build stays fast as the codebase grows.
-
Tests that run fast
Unit tests with coroutine test utilities and mocks where needed, so behavior is checked without flaky timing.
-
AI output, reviewed
Uses coding assistants for boilerplate and first drafts, and checks that generated coroutine code cancels and fails correctly.
HIRING GUIDE
How to hire Kotlin developers
Kotlin shows up in three different jobs: Android apps, backend services and shared multiplatform code. This guide covers how to tell which one you are hiring for, what to test, the red flags and when a dedicated Kotlin developer is the wrong hire.
What does a Kotlin developer do?
Writes and maintains software in Kotlin. On mobile teams that means Android apps; on backend teams it means services built with Spring Boot or Ktor on the JVM; on some teams it means shared business logic with Kotlin Multiplatform.
Across all three, a good Kotlin developer uses the type system and coroutines to make whole classes of bugs impossible, and keeps interop with existing Java code clean.
Android, backend or multiplatform: which do you need?
Kotlin on Android and Kotlin on the server are different jobs with different tooling. Put the platform in the brief first, then the frameworks.
If your need is an Android app and its releases on Google Play, an Android developer profile fits best. If it is services, APIs and databases, you are hiring a backend developer who writes Kotlin.
Mixed Java and Kotlin codebases
Many teams adopt Kotlin file by file inside a Java codebase. That works well, but only if someone understands how nullability, annotations and generics cross the boundary.
Ask the candidate how they would introduce Kotlin into one of your Java modules and what they would convert first. A strong answer is incremental and starts with tests.
What to test in a Kotlin developer interview
Give a small task close to your real work: a function that calls two services concurrently with coroutines, combines the results and handles a timeout. Read how they scope the work and model the errors.
Then ask about a production bug they fixed that the type system could have prevented. You want to hear what they changed in the types, not only in the logic.
Red flags in Kotlin developer candidates
The double-bang operator everywhere. Forcing values that may be null brings back exactly the crashes Kotlin was designed to remove.
GlobalScope for background work. Coroutines launched without a proper scope leak, keep running after they should stop and swallow errors.
Java written in Kotlin syntax. No data classes, no sealed types and mutable state everywhere means the team gets the cost of a new language without the benefit.
Only one side, presented as both. A candidate strong on Android but with no backend experience, or the reverse, may still be a good hire, as long as it matches your brief.
Generated code they cannot explain. Ask them to walk through coroutine code an AI assistant wrote for them. If they cannot say how it cancels, nobody reviewed it.
When should you not hire a dedicated Kotlin developer?
When your backend is Java and nobody plans to adopt Kotlin, a Java developer is the simpler hire. When your app must ship on iOS and Android with one team, consider a cross-platform framework.
It is also the wrong hire when nobody on your side can review code or set priorities. A single developer without a technical lead tends to build what is interesting instead of what the business needs.
How much does it cost to hire a Kotlin developer?
It depends on seniority, the scope of the work and the country the person works from, and any single number describes one scenario and calls it a price.
What is worth understanding is the shape. On Managed Staffing it is one all-in monthly rate per person, with payments, compliance and replacement cover inside it. On Direct Hire it is a one-time fee of 20% to 30% of first-year base salary and the person goes on your payroll. We quote your number before you interview anyone.
Why hire a Kotlin developer in Latin America?
Overlap. Development runs on code review, standups and incidents, and Latin America and the Caribbean share most of the US working day, so those happen in real time instead of overnight.
The second reason is communication. Your developer writes pull request descriptions, technical notes and status updates in English, and we screen English live on a call.
How does CloudTask hire for this role?
You send whether the work is Android, backend or multiplatform, the frameworks you run, the kind of work and the hours you need covered. We source against that brief and come back with 3 to 5 matched profiles within 48 hours, each one screened on a live call and checked against the stack you named.
You interview and choose. On Managed Staffing we handle payments, compliance and onboarding and stay involved with check-ins. On Direct Hire the person joins your payroll from day one. Both carry a replacement guarantee: 24 months on Managed Staffing, 6 months on Direct Hire.
