We're now growing our team in Poland and want to be upfront about how this role is structured. As we don't yet have a legal entity in Poland, we work with an Employer of Record (EOR) or umbrella company to onboard talent in the region. This means the role is offered on a 2 year fixed term basis via an international contractor agreement — and is fully remote.

Purpose of the job

As a Software Engineer, you’ll be a core member of a cross-functional product squad, building new features and services as part of a modern, cloud-native platform. You’ll be working with experienced engineers, Product Managers, and QAs to develop scalable, well-tested systems using a contemporary tech stack; all in a greenfield environment.

This is a hands-on role, where you’ll spend most of your time coding, refining technical tasks, and solving real user problems through software. You’ll learn by doing, pairing with others when needed and contributing to everything from front-end interfaces to backend services and APIs.

We’re big on engineering quality; this entails end-to-end CI/CD, observability, infrastructure-as-code, and automated testing are baked into how we work. You’ll be encouraged to explore new ideas, use AI-powered tools where helpful, and continuously sharpen your skills as an engineer.

If you’re looking for a role where you can write great code, grow your experience across the stack, and ship features that matter, please apply.

Key Responsibilities:

Design and write clean, reliable TypeScript code for both frontend and backend services.

Collaborate with engineers, QAs, Product Managers, and Engineering Managers to plan, build, and release new features.

Write unit and integration tests, and contribute to a robust CI/CD setup that ensures safe, reliable releases.

Deploy and operate software in AWS using infrastructure-as-code tools like Terraform.

Take part in code reviews, retrospectives, and regular feedback sessions to improve as an engineer.

Look for opportunities to improve development workflows using AI-powered tooling and automation.

Knowledge skills and experience required

Solid experience with TypeScript (Node.js & React) and strong fundamentals in JavaScript.

Able to build and consume RESTful and GraphQL APIs, with experience working with databases like PostgreSQL or MongoDB.

Comfortable with basic cloud development in AWS, using CI/CD pipelines (we use GitHub Actions) and tools like Terraform.

Familiar with writing tests in Jest, and understand the importance of test coverage, maintainability, and regression safety.

Proficient with Git and familiar with Jira, Confluence, and collaborative engineering workflows.

You enjoy solving engineering problems and are comfortable breaking down tasks, asking questions, and working through ambiguity.

You’re eager to learn from your teammates and grow as a full-stack engineer, actively participating in a team committed to continuous improvement.
