About the Team

You will join the team that builds and operates the firm’s core data platform — the backbone for market data and trading data across the business. We capture high-throughput market data from global exchanges and venues, run real-time and batch pipelines, and serve a multi-backend data warehouse used by trading desks, quants, and analytics.

Accuracy, reliability, and timeliness are everything: our outputs feed live trading, research, and reporting. We’re hiring a Data Engineer to help build and operate this platform end-to-end — from ingestion through pipelines and storage to the infrastructure that runs it all.

Key Responsibilities

• Build and operate data pipelines end-to-end — ingestion from exchange/venue APIs (REST/WebSocket), streaming (Kafka), batch processing, and delivery to storage.
• Develop platform services, tooling, and jobs in Java and Python, with a focus on code quality and operational reliability.
• Operate and scale our storage backends — Apache Iceberg (lakehouse), ClickHouse (analytics/OLAP), and MySQL/PostgreSQL (transactional) — including schema design and performance tuning.
• Keep the platform healthy — monitoring, alerting, data-quality checks, backfills, and incident response across pipelines and infrastructure.
• Support data consumers — trading desks, quants, and analytics — with query support, schema/source onboarding, and client-library maintenance.
• Drive platform evolution — backend migrations, performance optimization, and CI/CD on Kubernetes — and onboard new data sources and venues efficiently.
• Work AI-native — use AI coding assistants and LLM tooling to accelerate development, debugging, and data operations, and help the team adopt AI across its workflows.

Qualifications

• Bachelor’s degree or above in Computer Science or a related field.
• 3–8 years in software or data engineering (we’ll calibrate level to your experience).
• Strong production skills in Java and/or Python.
• Solid SQL and hands-on experience with at least one of MySQL/PostgreSQL, ClickHouse, or a comparable columnar/time-series store (schema design, query performance).
• Experience building and operating data pipelines (batch and/or streaming) in production.
• Experience integrating with external APIs (REST/WebSocket) and handling real-world constraints — auth, rate limits, partial outages, schema drift.
• An ownership and operational mindset: you care about data quality, monitoring, reproducibility, incident response, and documentation.
• Proactive in using AI tools (AI coding assistants, LLMs) to work faster and smarter, with curiosity about applying AI/ML to data problems.
• Eagerness to learn — open to picking up Rust and new storage technologies as the platform evolves.
• Strong communication skills; comfortable working across business and technical teams.
• Fluency in Chinese and English.

Preferred Skills

• Rust, or a strong interest in learning it for performance-critical components.
• Hands-on experience with Apache Iceberg / lakehouse, ClickHouse, or Kafka (Spark a plus for Iceberg integration).
• Exposure to Kubernetes, GitLab CI/CD, and cloud infrastructure (Alibaba Cloud, AWS, or GCP).
• Workflow orchestration tooling (Airflow, Celery, or similar).
• Exposure to AI/ML tooling (MLflow, model serving) or building/serving data for ML and AI workloads.
• Experience with market data, trading, or financial/crypto data at scale.

Perks & Benefits

• Competitive total compensation package
• L&D programs and education subsidy for employees’ growth and development
• Various team building programs and company events
• Wellness and meal allowance
• Comprehensive healthcare schemes for employees and dependants
• More that we love to tell you along the process!
