Description
Candidate Profile — Full-Stack Product Engineer
We are looking for a very strong senior-level Full-Stack Engineer with a product engineering mindset.
This is NOT a typical “CRUD full-stack developer” role.
The client puts very high emphasis on:
debugging skills
code reasoning
ability to read and understand existing production code
strong JavaScript fundamentals (especially asynchronous behavior)
live problem-solving during technical discussions/interviews
Core Requirements
Frontend / JavaScript
Must-have:
Strong modern JavaScript / TypeScript knowledge
Deep understanding of:
async/await
promises
event loop
asynchronous flows
debugging async behavior
Comfortable reading and debugging existing frontend code live
React experience preferred
Backend
Must-have:
Experience with at least one statically typed backend language:
Java
Kotlin
C#
Go
TypeScript backend experience can also work if senior enough
Experience working with production systems and real business logic
Engineering Mindset
Very important:
Strong debugging and analytical thinking
Able to explain reasoning step-by-step
Comfortable during live coding / pair debugging sessions
Able to navigate unfamiliar codebases
Product-oriented mindset
Strong communication skills in technical discussions
Preferred Background
Strong preference for engineers who:
worked in product companies or SaaS environments
handled real production incidents/issues
worked with complex integrations or event-driven systems
have experience beyond simple feature delivery
NOT a Good Fit
Please avoid candidates who are mainly:
simple CRUD developers
purely outsourcing/task-based engineers
frontend developers with weak JavaScript fundamentals
engineers who struggle explaining their thought process
candidates relying heavily on AI without understanding the code deeply
Interview Process Notes
The client evaluates:
how candidates think live
how they debug
how they reason about asynchronous code
ability to explain existing code and solutions clearly
Candidates must be comfortable with:
live technical discussions
screen-sharing sessions
real-world debugging scenarios
discussing trade-offs and architecture decisions
Overall, we need a true senior product engineer, not just someone matching keywords in a CV.
