Engineering Organization & Culture

At Bullish, we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform centered on security and compliance, requiring a commitment to technical excellence that extends beyond delivering code. As a global organization, we set a high bar for those driven to do their best work alongside experienced, deeply specialized peers.

Engineers here treat development as a craft and own the outcome from concept to deployment. Our teams bring structure to ambiguity and shape the frameworks that support a global organization. We refuse to compromise on quality and seek problem solvers who thrive on complex technical challenges with real market consequences.

The Team: Trading Product Engineering

The Trading Product Engineering team builds the core distributed systems that drive the global trading experience on Bullish Exchange. We own the end-to-end order lifecycle, orchestrating a hybrid matching engine that combines a Central Limit Order Book with proprietary Automated Market Making. Our high-throughput APIs enable trading across Spot, Futures, and Options. The work demands absolute correctness in managing complex financial state transitions, translating intricate market structures into scalable solutions.

What You'll Do

• Design and deliver reusable, reliable, low-latency Java code that powers the Exchange.

• Raise the bar on code quality, organization, and automation as the system scales under load.

• Profile and resolve performance bottlenecks in the order-processing path.

• Improve stability through automated tests at the unit, integration, and performance layers.

• Collaborate across a distributed team of engineers, product managers, and project managers.

What You'll Bring

• Strong Java (17+) fluency with experience in performance tuning.

• Track record of designing and building systems for high throughput and low latency.

• Hands-on experience with agentic AI development: LLM integration, prompt engineering, and SDLC automation.

• Solid understanding of middleware and messaging technologies such as Chronicle Queue, RabbitMQ, Aeron, and Kafka.

• Working knowledge of Spring or Micronaut, Docker, and Kubernetes.

• Deep knowledge of testing methodologies, SDLC practices, and CI/CD pipelines.

• Ownership of the components the Exchange depends on.

Nice to Haves

• Experience working on core trading functionality such as order matching and orderbook generation.

• Familiarity with financial derivative products (Options, Futures), the FIX protocol, and related workflows.

• Understanding of blockchain technologies.
