Calypso Developer

The Role at a Glance

Calypso Engineer

• Work with fixed income, foreign exchange, and derivatives trading systems at a top North American bank
• One of the largest Calypso deployments in the world
• Fully remote, for residents of Poland and Romania only

This role requires experience with Calypso and strong Java development skills. You’ll be extending the platform directly, not just configuring it through a UI. If you like digging into hard problems and want to work on a platform used by one of the largest Calypso deployments in the world, join us.

Why Join Us?

• Build on Calypso, working at one of the largest Calypso deployments in the world, on fixed income and derivatives workflows.
• Real engineering ownership: you’ll be part of the core development and business analyst team, not merely providing support.
• Join a growing team: the business is expanding, and Calypso's footprint is growing with it.
• Long-term, fully remote role with the stability that comes from working with a major bank.

A successful candidate will be a strong Java engineer with prior Calypso experience. You should be analytical, curious, and comfortable asking questions or trying things rather than waiting to be told.

This is a fully remote role for a professional based in Poland or Romania. You will be working through a Polish company that will provide support and administrative assistance to make you successful in the role. We are looking for people to join the team long-term.

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

Time zone: you’ll need a 3–4 hour daily overlap with US Eastern business hours, as most meetings happen in the morning. During onboarding, you will need to be more flexible and provide more time-zone overlap.

What we offer

• Work that matters: build on one of the largest Calypso deployments in the world.
• Professional growth: collaborate with smart, highly capable developers and business administrators in a supportive and challenging environment.
• Direct collaboration: work directly with the client team in North America and Poland.
• Long-term commitment: this is not a fixed-scope or fixed-term outsourcing role; the team values people who want to grow and contribute long-term.
• Flexibility and remote work: fully remote position based in Poland or Romania, with increasing schedule flexibility after onboarding.
• Competitive compensation: top pay and ample time-off options.

Responsibilities

• Build and maintain Calypso APIs, workflows, engines, events, reporting, and scheduled tasks using Java.
• Integrate Calypso with external systems using MQ, Kafka, and web services/HTTP.
• Write and optimize SQL, troubleshoot database issues, and work with Oracle-backed Calypso environments.
• Support Calypso applications in Linux/Unix environments, using shell scripting to automate development and operational tasks.
• Maintain and improve build, deployment, and release processes using GitHub, Azure DevOps, Ansible, and JFrog Artifactory.
• Work from requirements and tickets defined by business analysts; think critically, contribute experience and domain knowledge, and help shape solutions for business users.
• Fix defects, participate in code review, and maintain code quality across the Calypso codebase.
• Support testing and validation of changes before production release.
• Use AI tools to accelerate development or testing where appropriate.

Requirements

Must have

• 5+ years of hands-on Calypso development experience; V17+ strongly preferred.
• Experience with APIs, workflows, engines, events, reporting, scheduled tasks, and external-system integrations.
• 5+ years of Java development experience.

• Strong SQL and database experience, preferably Oracle.
• Strong DevOps experience covering source control, build automation, deployment automation, and release management, including hands-on use of GitHub, Azure DevOps, Ansible, and JFrog Artifactory.
• Solid understanding of fixed income, FX, interest-rate derivatives, and credit derivatives.
• Experience supporting high-volume trading environments in investment banking/capital markets.
• Ability to work independently with minimal supervision, collaborate in cross-functional teams, and operate successfully within structured project environments.
• Ability to deal with ambiguity: read between the lines, ask clear questions, use AI tools to fill gaps, and proactively develop solutions.
• Strong communication skills and comfort working in high-stakes, trader-facing environments.
• Ability to maintain a 3–4 hour overlap with US Eastern business hours, with flexibility during crunch periods.

Nice to have

• Experience using AI tools to speed up development or testing work.
• Experience working remotely with North American firms.
