About the Role (Java)

We're looking for a curious and motivated Junior Backend Engineer to join our team. You'll be building backend services and REST APIs and working with AWS or Azure infrastructure.

Our projects use Python or C#, but since all of our code is written with AI, we are considering candidates with any OOP language, including JavaScript and Java. What matters is how you think about software: object-oriented design, APIs, and data.

We work in pairs — juniors are always paired with another junior or someone at a similar level, not just for code reviews, but for day-to-day coding, architecture decisions, and problem solving, with seniors close by whenever you need help. This is production work: you'll ship services that customers rely on, with the safety net of another teammate beside you.

The client is US-based, so the team works US business hours; for engineers in Ukraine, this means your working day ends around midnight Kyiv time. This role can be full-time or part-time, depending on your availability.

What You'll Work On

• Backend Services & APIs — build and maintain REST APIs and backend services for client platforms, with clear contracts and automated tests.
• AWS or Azure Infrastructure — work with cloud infrastructure on AWS or Azure, depending on the project.
• CI/CD using GitHub Actions or Azure DevOps pipelines.

Tech Stack

• Backend — Our projects use Python or C#, depending on the engagement. You do not need to know either one — all code is written with AI, and you'll learn the project's framework on the job.
• Cloud — AWS or Azure, depending on the engagement. Nice-to-have, not required.

Working Hours & Format

This role can be full-time or part-time, depending on your availability. It's fully remote. Our client operates on US business hours, so the schedule needs to align with US time zones — for engineers based in Ukraine, your working day will end around midnight Kyiv time.

Requirements

Solid fundamentals in OOP and comfort with at least one OOP language — it does not matter which.

Exposure to AWS or Azure is a plus, but not required — you'll pick up what you need on the job. We care more about your curiosity and attitude than your CV.
