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
If you want your engineering to directly move revenue — let’s launch the future together
