Description:
We are looking for a Lead Engineer to drive backend development of the applications, frameworks, and tools at the core of Bullish Exchange. You will design and build high-performance trading engine components alongside a distributed team based primarily in Hong Kong and Singapore.
This is a hands-on technical role with leadership expectations: setting the technical bar, mentoring engineers, and shaping how the team works. Bullish Engineering operates on an AI-first principle, using LLMs throughout the SDLC to speed up development, review, and automation.
What You'll Do
- Design and deliver reusable, reliable, low-latency Java code that powers the Exchange.
- Apply deep TradFi product knowledge across Spot and Derivatives to ensure functional correctness and market fit.
- Identify bottlenecks and engineer solutions that improve throughput, latency, and reliability.
- Set the bar for code quality, automation, and design across the team.
- Mentor engineers and define what good looks like across the organization.
- Collaborate closely with engineers, product, and project management across Hong Kong, Singapore, and other Bullish hubs.
What You'll Bring
- 12+ years of Java backend engineering experience, with a focus on front-office execution and trading technologies.
- Expert-level Java (17+), including the JVM, concurrency primitives, and collections.
- Proven track record of architecting and building low-latency trading systems from the ground up.
- Strong command of data structures, algorithms, and TDD/BDD practices, including thorough unit test coverage with JUnit and Mockito.
- Hands-on experience with Spring or Micronaut, Docker, and Kubernetes.
- Working knowledge of messaging technologies such as Kafka, RabbitMQ, or Solace.
- Solid understanding of Spot, Futures, and Options markets.
- Hands-on experience with agentic AI development: LLM integration, prompt engineering, and SDLC automation.
- Familiarity with Git/GitHub, JIRA, Confluence, and CI/CD practices.
- Bachelor's degree in Computer Science or a related technical field.
