Remote Warszawa Wrocław Kraków Poznań Katowice, Czech Republic Bank of Montreal Full time
  • 2+ years of professional core Java development experience.
  • Knowledge of the internals of Java data structures.
  • Understanding of programming concepts, including algorithms, complexity, and data structures.
  • Strong analytical and problem-solving skills.
  • Ability to clearly explain non-trivial systems and algorithms.
  • Open mind, curiosity, and a strong desire to learn new technologies and business domains.
  • Good verbal and written communication skills and experience working remotely.
  • Strong collaboration and teamwork skills.
  • Humility to ask questions where necessary.
  • Ability to align your working schedule to US Eastern business hours during onboarding.


We seek a strong Java developer to join a trading systems team at Bank of Montreal, Capital Markets. You will program in core Java, building and enhancing the trading platform and its supporting systems. You will work closely with developers in North America and Poland and interact with other teams, to implement new trading features and improve the existing trading platform and peripheral systems.

Read on if you want to work with large, low-latency trading systems in Java. We’re looking for top-notch developers who want to work with smart and capable people.

A successful candidate will have a few years of experience in software development and the right mix of technical knowledge and soft skills. You must be very strong in Java and programming in general. You must also be curious, open-minded, and desire to learn new things. English proficiency is a must.

This is not a role for someone who likes to integrate external systems, frameworks, and libraries, or shuffle data between external APIs and databases. Sure, there is a bit of that as well, but the system is mostly built in core Java and there are very few external dependencies. You must be great at programming to succeed in this role. Knowing enough to put together a system from blocks is not enough. You must be curious about how things work on the inside and to strive for a thorough understanding of technology.

This is a fully remote backend Java development role for a developer in Poland. You will be working through a Polish company that will provide the support and administrative assistance to make you successful in the role. We are looking for people to join the team long-term. This is not a fixed-scope or fixed-term project. This is not a short-term outsourcing project.

To ensure efficient onboarding, you’ll work in sync with the American team during US Eastern business hours for the first two months. Working this way maximizes your time overlap for answering questions, which means you can learn quickly. That means working until 21:00 CET. After that, your schedule will gradually shift closer to standard Polish business hours.

Please do not apply if you do not live in Poland. Polish citizens, as well as legal residence with permission to work in Poland are welcome.
