Remote Full-Time | Development

Responsibilities

In the role of Middle Full-Stack Engineer, you will:

  • Take features end-to-end, from backend and frontend implementation to production release.
  • Use AI assistants daily and critically review AI-generated code before merging.
  • Dive into and extend the existing codebase, read other developers' code, and add new functionality without regressions.
  • Work with payment and funnel flows (paywall, subscriptions, webhooks).
  • Write tests for your own logic, participate in code reviews, and address feedback.
  • Decompose tasks and ask clarifying questions before writing code.

Requirements

We are looking for a candidate who:

  • Has confident command of TypeScript (generics, type safety, and avoids any entirely).
  • Has a deep understanding of modern SPA frameworks (Angular / Vue / React), including components, reactivity, and state management. Angular experience is not required upfront, but readiness to fully ramp up into it is essential.
  • Has experience working with NestJS (modules, dependency injection, controllers/services, request lifecycle).
  • Works with SQL and ORM tools (TypeORM), can write queries, and understands transactions and the N+1 problem.
  • Uses AI tooling confidently (Claude Code / Cursor / Codex): can break tasks into prompts, iterate on solutions, and review generated code before shipping it.
  • Has solid Git workflow skills (branches, meaningful commits, pull requests).

Nice to Have

  • Experience with other backend technologies and databases.

We Offer

Why Solvy? We offer:

  • Self-realization and growth:
    • Build a product from scratch and influence key decisions.
    • Grow together with the business at a fast pace.
    • Work in an environment with space and freedom to act.
    • Become part of a strong team of A-players who are ready to share expertise and boost each other.
    • Use learning opportunities: internal and external lectures, a large corporate library, compensation for external courses, English lessons, and speaking clubs.
  • Comfortable working conditions:
    • Work remotely or visit the office in Kyiv, coworking spaces in Lviv or Warsaw.
    • Plan your working day independently - we offer a flexible schedule, because results matter most.
    • Recharge and rest: 28 working days of paid vacation per year, up to 30 days of sick leave, and all public holidays fully covered.
    • Optionally arrange a transfer - swap a working day with a day off and vice versa.
  • Care and support:
    • Take care of your health: we provide medical insurance, a Mental Health program, and compensation for sessions with a psychologist.
    • Join socially meaningful initiatives, including the Ukrainian Victory Support program.
    • Participate in quarterly team buildings - online or offline - to make teamwork easy and enjoyable.
