Remote Java developer work from Canada, on US teams
What US teams look for in a Java engineer, how working their hours from Canada plays out and how the Ryz Labs process works.
By the Ryz Labs team · Updated October 2026
Ryz Labs places senior Java developers on US companies’ teams. You work remotely from Canada, on US business hours, with the same tools, meetings and leads as the rest of the team.
What the work is like
You join the engineering team of a US company and report to its technical leads. You take part in stand-ups, code reviews, planning and demos like anyone else on the team. Ryz works with Fortune 500 engineering teams and with fast-growing companies.
How your day lines up with a US team depends on your province:
- Ontario and Quebec (Eastern Time): the same clock as New York.
- Atlantic Canada: one hour ahead of New York in Nova Scotia, New Brunswick and PEI.
- Manitoba (Central Time): the same clock as Chicago; Saskatchewan matches Chicago in winter and Denver in summer.
- Alberta (Mountain Time): two hours behind New York.
- British Columbia (Pacific Time): the same clock as California.
Everything happens in English and in real time with the team, so clear communication matters as much as technical depth: explaining a decision, asking for context and pushing back when something does not add up.
What US teams look for in a Java developer
Java remains at the core of critical systems: financial services, logistics, healthcare and high-volume platforms. Teams want experience with Spring Boot and cloud microservices.
- Modern Java: Java 17 and 21, records, streams and virtual threads.
- Spring Boot: Spring Data, Spring Security and multi-environment configuration.
- Microservices: Kafka or REST communication, resilience and tracing.
- Persistence: JPA and Hibernate, query tuning and transaction management.
- Testing: JUnit 5, Mockito and Testcontainers.
- Cloud: Docker, Kubernetes and AWS or Azure services.
Topics worth reviewing
Before your interviews, have clear answers on topics like these:
- Designing transactions and handling concurrency with JPA.
- Resilience patterns between microservices: timeouts, retries and circuit breakers.
- What changed in Java 17 and 21, and when to use it.
- How you would approach modernizing a monolith.
How the selection process works
- Apply. You apply through the Join the team page with your experience and main stack.
- AI-assisted technical interview. A structured technical conversation about your real experience. People make the decisions, not the AI.
- Interviews with Ryz recruiters. They go deeper into your experience, how you work and how you communicate.
- Introduction to the team. When a team matches your profile, we introduce you. The last step is a final interview with that team.
It is a demanding process. Of the tens of thousands of engineers we interview, only the top 1% join a team.
Who we look for
- Senior experience with Java, with systems in production.
- Clear, confident spoken and written English for daily teamwork.
- Based in Canada and available during US business hours.
- Ownership: taking an ambiguous problem all the way to production.
- Comfort with asynchronous work across time zones.

Join the team →FAQ
Does Kotlin count?
Yes. Several teams use Kotlin alongside Java on the JVM, though the core we assess is still Java and Spring.
Is there room for modernization work?
Yes. Moving legacy systems, mainframes included, to modern API-first architectures is part of the work Ryz does.
Do you work with junior engineers?
Ryz works mainly with senior engineers: people who have shipped systems to production and can work independently on a US team.
Can I apply with experience in more than one stack?
Yes. Many engineers know several technologies well. In the interviews we go deep on what you know best and what you have shipped.
What does Ryz Labs do?
Ryz Labs places senior engineers and AI pods on US companies’ teams. Founded in 2021, it is headquartered in Calabasas, California (Los Angeles area), and has more than 200 people.
How is AI used in the selection process?
One stage is an AI-assisted technical interview. It structures the process, but people make the decisions: Ryz recruiters review every profile.
