At TechBiz Global, we are providing recruitment service to our TOP clients from our portfolio. We are currently looking for a skilled Java Backend Engineer to join one of our clients' teams.

Develop and maintain RESTful APIs for integrations with external systems and internal services.
Implement and optimize FIX protocol-based APIs for financial/trading system integrations.
Ensure low-latency, high-availability, and secure backend architecture.
Write clean, maintainable, and well-documented code following industry best practices.
Collaborate with DevOps to deploy and monitor services in production environments (AWS, GCP, Azure, or on-prem).
Optimize database performance (SQL/NoSQL) and design schemas for ATS workflows.
Conduct code reviews, unit testing, and integration testing to maintain code quality.
Troubleshoot and resolve performance, scalability, and reliability issues.
Stay updated on emerging technologies, protocols, and best practices in API development and backend engineering.

Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.

Experience with databases (PostgreSQL, MySQL, MongoDB, Redis, etc.).
Proficiency in Git, CI/CD pipelines, Docker, Kubernetes.
Strong understanding of security principles (OAuth2, JWT, SSL, encryption).
Excellent problem-solving, debugging, and analytical skills.

Nice to Have

Experience with financial systems, trading platforms, or ATS solutions.
Knowledge of messaging systems (Kafka, RabbitMQ, Redpanda, Chronicle Queue, etc.).
Exposure to cloud services (AWS/GCP/Azure).
Familiarity with microservices architecture and event-driven systems.
