You’ll work closely with senior engineers, product managers, and trading teams to design and deliver performant, scalable systems.

• Develop and maintain backend services in Java, with supporting components in Python and Go.
• Design and implement normalized database schemas to model complex order life cycles and trader workflows.
• Build and enhance trader‑facing user interfaces using React, Type Script, and modern web technologies.
• Work with APIs across the stack, including Web Socket, FIX, and REST, to integrate with internal strategies and external venues.
• Collaborate with product and engineering teams to define technical requirements and ship reliable, production‑ready code.
• Contribute to performance monitoring, alerting, and observability for the systems you help build.
• Participate in code reviews, stand‑ups, and Agile development cycles.

• Proficiency in Java, with working knowledge of Python or Go.
• Familiarity with React, Type Script, and building frontend components.
• Strong understanding of relational databases, data modeling, and SQL.
• Interest in electronic trading workflows, order state transitions, and real‑time system behavior.
• Comfort working with APIs and async communication (e.g., Web Socket, FIX, REST).
• Clear communication skills, attention to detail, and a collaborative mindset.

• Exposure to trading systems (OMS/EMS), financial workflows, or crypto markets.
• Experience working with FIX protocol or market data feeds.
• Background in distributed systems or event‑driven architectures.
• Familiarity with message bus frameworks (Kafka, Aeron, Chronicle, etc.).
