Java was designed as a general language capable of programming software for commercial use. It is based on several previous languages such as Objective C, C++, and C#. Java can be used on most major operating systems, including Windows, Apple, and Linux distributions. There is also a Java virtual machine, which allows programmers and developers to work on different operating systems within a single platform.

They participate in code reviews, daily stand-ups, and sprint planning meetings, sharing progress and addressing technical challenges collaboratively. Effective communication and coordination with other departments, such as DevOps for deployment or UX/UI teams for interface integration, are essential for delivering high-quality applications.

Job description

Job Title: Java Developer 
Location: NYC, NY OR NJ
Length: 6-10 months
 
We are seeking an Associate Java Developer to join our trading technology team and support the development of scalable, resilient microservices that underpin our execution and order management platforms. This role is ideal for a mid-level engineer who has strong Java fundamentals and is eager to deepen their experience in financial systems, distributed architectures, and performance-sensitive applications.
You’ll work closely with senior engineers, quants, and product partners to enhance existing services, build new functionality, and ensure the platform meets availability, performance, and risk requirements.
Core Responsibilities
• Application Development: Develop and enhance Java-based microservices using Spring Boot within a distributed trading environment.
• Feature Delivery: Collaborate with Product Managers and Quant teams to implement execution logic and platform enhancements under the guidance of senior developers.
• Performance & Reliability: Participate in performance tuning, troubleshooting, and improving application stability, with mentorship on latency-aware development practices.
• Risk & Controls: Assist in implementing pre-trade checks, validation logic, and operational safeguards to support “safe trading” requirements.
• Code Quality: Contribute to clean, well-tested code through unit testing, code reviews, and CI/CD best practices.
Domain Exposure
• Trading Workflow: Familiarity with or interest in the trade lifecycle (e.g., order capture, execution, downstream processing).
• Market Concepts: Basic understanding of execution workflows, market data, or order routing is a plus, but not mandatory.
• Regulatory Awareness: Exposure to financial systems with audit, compliance, or controls is beneficial.
Technical Qualifications
• Java Development: Strong proficiency in Core Java (Java 11+), including object-oriented design, basic concurrency, and collections.
• Spring Framework: Hands-on experience with Spring Boot and RESTful services; exposure to Spring Cloud components is a plus.
• Distributed Systems: Experience building or supporting microservices in a containerized environment (Docker; Kubernetes exposure preferred).
• Messaging & Data: Familiarity with messaging platforms (Kafka, RabbitMQ, or similar) and working knowledge of SQL and/or NoSQL databases.
• Testing & CI/CD: Experience writing unit and integration tests and working with CI/CD pipelines (e.g., Jenkins, GitLab CI).
