About the project

E-commerce domain (Sweden). We’re building an internal management platform that covers multiple aspects of online sales for a wide range of products. The system includes numerous integrations and data flows — fetching data from external sources and pushing updates to other systems. The engineer will work directly with the client, clarify requirements, demo progress, and deliver end-to-end backend functionality (admin panel on the front-end side — basic skills are enough).

Requirements

4+ years of commercial experience in backend development (Node.js);
Strong proficiency in JavaScript (ES6+) and TypeScript;
Hands-on experience with Node.js frameworks (NestJS is a plus / preferred);
Solid understanding of REST APIs (and/or GraphQL), API versioning, and integration patterns;
Strong experience with databases: PostgreSQL (plus understanding of indexes, transactions, performance);
Understanding of software architecture, design patterns, and ability to design solutions from scratch;
Good knowledge of testing practices (unit/integration), debugging, and quality ownership;
Ability to work independently: clarify requirements, estimate tasks, manage time, and validate results;
Strong communication skills and readiness for regular client communication (weekly sync + async via Slack/email);
English: Upper-Intermediate or higher.

Would be a plus

Experience starting a project from scratch (architecture, boilerplate, tooling);
Basic DevOps skills: CI/CD basics, deployments, environment configuration;
Experience with AWS (any relevant services);
Docker and basic containerization knowledge;
Experience with microservices or modular monolith approach;
Experience with message queues (SQS/RabbitMQ/Kafka) and background jobs;
Experience with integration-heavy platforms (e-commerce, ERP, PIM, OMS, shipping, marketplaces).

What you will do

Design and develop backend services using Node.js/TypeScript, focusing on scalability and maintainability;
Build and maintain integrations (pull/push data, handle third-party APIs, webhooks, retries, idempotency where needed);
Collaborate directly with the client to clarify requirements, align expectations, and demonstrate progress;
Own the delivery cycle: estimates, implementation, testing, and release readiness;
Ensure robust error handling, logging, and monitoring-ready code;
Support basic admin-panel needs (basic FE involvement when required — no complex UI work).

What you will get

Competitive salary and good compensation package;
Exciting, challenging and stable startup projects with a modern stack;
Corporate English course;
Ability to practice English and communication skills through permanent interaction with clients from all over the world;
Professional study compensation, online courses and certifications;
Career development opportunity, semi-annual and annual salary review process;
Necessary equipment to perform work tasks;
VIP medical insurance or sports coverage;
Informal and friendly atmosphere;
The ability to focus on your work: a lack of bureaucracy and micromanagement;
Flexible working hours (start your day between 8:00 and 11:30);
Team buildings, corporate events;
Paid vacation (18 working days) and sick leaves;
Cozy offices in 2 cities ( Kyiv & Lviv ) with electricity and Wi-Fi (Generator & Starlink);
Compensation for coworking (except for employees from Kyiv and Lviv);
Corporate lunch + soft skills clubs;
Unlimited work from home from anywhere in the world (remote);
Geniusee has its own charity fund.
