Kotlin Team Lead

What you'll do

The Team Lead role sits above the Kotlin Engineer listing and shifts the work from producing answers to protecting their quality. You spot-check Kotlin items from trainers and QAs, review AI output for coroutine misuse, unsafe null handling, non-idiomatic style and invented APIs, and give feedback by direct message.

You also communicate guideline changes on Discord, answer questions about syntax, coroutines, Android/JVM context and tests, track inactive contributors, write Kotlin style guides and honeypots, and run onboarding calls. The ad says there is no immediate project for this role; qualified applicants are first in line when a relevant project opens, and the role gives access to future projects through the expert network.

Who fits

• Bachelor's or Master's in computer science, software engineering or IT, or equivalent experience
• 3+ years in Kotlin, Android, JVM backend, code review, QA or technical mentoring
• Strong Kotlin knowledge: data and sealed classes, generics, extension functions, coroutines, flows, exception handling, Java interop
• Ability to spot incorrect coroutine usage, unsafe null handling and non-executable code
• Strong English for technical feedback

Nice to have

• Android, Jetpack Compose, Gradle, Ktor, Spring Boot, JUnit, MockK, Espresso, CI/CD
• Leading remote teams of trainers or QAs (strongly preferred)
• AI training, LLM evaluation or rubric-based code review

What it pays

The ad states up to $65 an hour, a ceiling. That is $10 over the Kotlin Engineer listing (up to $55) and just under the JavaScript Team Lead (up to $70), but unlike the engineer role it is open to US applicants only. The listing does not publish payment terms; the process and payout details are on the company page.

Worth knowing

Good:

• Top Kotlin ceiling in this batch
• Selection includes a domain-specific task
• Only 3 years of experience stated

Less good:

• US only, while the engineer role is open to 17 countries
• No project open yet
• Lead duties pull time away from code review
• Monitored hourly work
