Our speed is our competitive advantage.
 

KMA is growing at least 3x year over year — and we’re looking for a Full Stack Developer who will help us scale even faster through strong engineering, structured thinking, and technology decisions that directly drive business outcomes.

About the role

This is a role for a product-minded engineer.

You will:

• Make architecture decisions
• Influence feature velocity
• Work on products with millions of users
• See your code reflected in retention, LTV, and revenue

We’re not hiring a task executor.
We’re hiring someone who naturally takes ownership.

What you’ll do

• Build and scale end-to-end features (frontend + backend)
• Architect scalable, performance-first solutions
• Reduce technical debt and eliminate bottlenecks
• Make tech decisions based on business leverage
• Partner directly with product and design
• Handle production issues with urgency
• Grow into a Tech/Team Lead role

Tech stack

Frontend: React.js, Next.js, Material UI, CSS
Backend: Symfony, Node.js, NestJS
Data & Infra: MySQL, PostgreSQL, Elasticsearch, Redis, Supabase, Firebase

We operate in high-load, SSR-heavy, AI-driven environments.

What matters to us

• You think in impact, not just implementation
• You ask “why” before “how”
• You don’t wait for permission to improve things
• You’re comfortable owning hard decisions
• Quality is your baseline

Especially relevant if

• You already operate at lead-level thinking
• You’ve built scalable systems
• You’ve worked in high-growth environments
• You want to build engineering, not just features

What you get

• Direct impact on products with millions of users
• High autonomy, low micromanagement
• Fast growth through ownership
• Strong engineering culture
• Remote or office (Kyiv/Warsaw)
• 40 days of paid leave
• Learning budget
• Military reservation option after probation
