Description:

We are looking for a talented Senior Full-Stack JavaScript Developer to join a small, agile team working on a SaaS platform that supports management consulting initiatives, business planning, and KPI tracking.

About the client:

Our client is developing a modern SaaS solution used for business planning and performance management. The team is now expanding to restart active development after a period of inactivity, focusing on improving existing functionality and building new, high-impact features. In this role, you’ll work on meaningful, data-intensive features with direct influence on the platform’s usability, performance, and future scalability.

Key Responsibilities:

  • Developing features end-to-end using Node.js, React, and TypeScript;
  • Addressing initial bugs and smaller improvements before moving to large new modules;
  • Building a major feature for structured annual and monthly business planning;
  • Working with complex data interactions and SQL logic (PostgreSQL);
  • Collaborating closely with the product owner with daily CET-time overlap;
  • Contributing across backend, frontend, deployments, and infrastructure tasks when needed;
  • Writing clean, production-grade code and participating in reviews.

Requirements:

  • 5+ years of experience as a Full-Stack JavaScript Developer;
  • Strong expertise in Node.js and React fundamentals;
  • Solid SQL knowledge, preferably PostgreSQL;
  • Fluent English for daily communication;
  • Senior ownership mindset – quality, responsibility, independence.

Nice to have:

  • Experience with AWS in production environments;
  • Experience with data-heavy or workflow-driven systems.

We offer:

  • Full-time position;
  • Challenging and interesting projects from European companies;
  • Competitive salary & bonus system;
  • Flexible work schedule;
  • Free English classes;
  • Knowledge-sharing events, e.g. DevTalks;
  • Unforgettable and interesting corporate events;
  • Team-buildings;
  • Accounting as a service.
