Senior Java Engineer (Trading Systems) @ Vistulo (for a major N. American bank)

Want to work on trading systems at a top N. American Bank

This isn’t just another dev role. It’s your chance to engineer the core of global trading.

We’re talking ultra-low-latency architectures, real-time market data, and automation at scale — all in an environment where milliseconds matter and billions move. You’ll work on greenfield and semi-greenfield projects, building trading systems for equities, options, FX (forex), and more.

If you thrive on complexity, love solving performance challenges under pressure, and want to collaborate directly with traders and product teams at the sharp edge of financial technology, this is your arena.

The Role at a Glance

• Senior Java Backend Engineer
• Building trading systems, including high-performance backend services for algorithmic order management and order routing (multiple projects & various asset classes)
• Fully remote for a top N. American bank (for residents of Poland or Romania)
• Part of the core team - this is not a legacy support role or an outsourced B team

This role requires experience building trading systems, ideally with order routing or algorithmic order management. Some capital markets experience is required.

If you enjoy working on low-latency, high-throughput trading systems, join us and build the next generation of high-performance capital markets solutions.

Why Join Us?

• Work on a large-scale, low-latency trading system.
• 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 very strong programmer with current Java development experience. They must also be curious, open-minded, and desire to learn new things. English proficiency is a must.

This role is for developers who excel at programming core Java from the ground up, not just integrating frameworks or APIs. If you’re fascinated by understanding systems ‘under the hood,’ this role is for you. Successful candidates enjoy geeking out about data structures and debugging application performance issues.

This is a fully remote backend Java development role for a developer in Poland or Romania. 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.

Only open to residents of Poland and Romania. Citizens and legal residents with permission to work in Poland or Romania are welcome.

What we offer

• Work that matters in the financial domain: You’ll be building a high-performance trading system at an established financial institution.
• Professional growth: Collaborate with smart, highly capable developers in a supportive and challenging environment.
• Direct collaboration: You will work directly with the client team in North America and in Europe.
• 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 with increasing schedule flexibility post-onboarding.
• Competitive Compensation: Top pay and ample time-off options.

Must have

• Current Java programming experience, with a strong understanding of programming concepts, including algorithms, complexity, and multi-threading, and Java’s language capabilities and standard libraries.
• Good knowledge of the data structures: familiarity with the Java collections framework, depth of understanding of the commonly used data structures, intuition on what to use when.
• Proven experience building backend services for front-office trading systems.
• Deep understanding of front-office workflows and electronic trading platforms (any asset class).
• Built or contributed to the algorithmic order management systems or order routing systems (any asset class).
• Expertise in multi-threading, event-driven systems, and performance tuning.
• Ability to break down complex workflows into maintainable, high-quality solutions.
• Strong communication skills and comfort working in high-stakes, trader-facing environments.
• Knowledge that is required for building low-latency (measured in microseconds) trading systems.
• Ability to align your work with a 6-hour overlap with US Eastern business hours.

Nice to have

• Exposure to time-series databases and market data integration.
• Familiarity with algorithmic workflows and pricing engines.
• A computer science degree from a top school.
