Are you a Java engineer who enjoys working on large scale and high performance software? Do you like the idea of handling billions of market data messages daily? Want to work in capital markets on financial trading systems? If so, read on.

The Role at a Glance

• Hybrid Operations and Java Engineer role

• Manage a large cluster of machines for aggregating market data

• Develop Java tools used for ingesting this market data into the bank’s systems

• Fully remote for a top N. American bank (for residents of Poland only)

• Part of the core team - this is not a legacy support role or an outsourced B team

We’re looking for a Java backend engineer (5+ years) with market data experience to join a major N. American bank. You’ll be responsible for managing and expanding a large system for ingesting market data from American and European exchanges. This is not a legacy maintenance or support role — you’ll be part of the core product team, managing a highly-performant, low-latency system used across the firm.

Are you a passionate Java developer who thrives on solving complex problems in low-latency, high-throughput trading systems? Join us and work on interesting financial system engineering problems.

Why Join Us?

• Work on a large-scale system processing billions of daily transactions.

• No Legacy: Join an actively developed system — the engineers who built it originally are still on the team.

• Collaborate with a world-class team of developers across North America and Europe.

• Enjoy the stability of a long-term, fully remote role that only a bank can offer.

A successful candidate will be a strong programmer with current Java development experience and an operations-focused mindset. They must also be curious, open-minded, and desire to learn new things. English proficiency is a must.

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.

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 be flexible and can shift closer to standard Polish business hours.

Only open to residents of Poland. Polish citizens, as well as legal residents with permission to work in Poland are welcome.

• 1st-tier work: This is not a technical support or legacy maintenance role. The system is functional and is actively being built and you will take part in updating it. The people who built the system are still part of the team.

• Long-term commitment: This is not a fixed-scope or fixed-term outsourcing role; we value people who want to grow and contribute long-term.

• Flexibility & remote work: Fully remote position based in Poland with increasing schedule flexibility post-onboarding.

• Competitive Compensation: Above-average pay and ample time-off options.

Responsibilities

• Manage a large cluster of Redline servers that aggregate market data - make configuration changes, conduct tests & validations, manage & schedule deployments (80% at the beginning).

• Maintain the Java library used to ingest the market data into the bank’s trading systems (20% at the beginning).

• Develop tooling to automate the operational steps above so the team can reduce time spent managing the Redline cluster, and shift work balance to 80% Java development and 20% operations.

• Improve observability and of the system so when things go wrong, we can easily pinpoint issues and efficiently resolve them.

• Create thorough test harnesses to ensure software stability and reliability.
