Senior Real-Time Detection Architect

Hytech; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Hytech is seeking a Detection Product Expert to own the design, development, and continual improvement of real-time detection capabilities. This senior IC role sits at the intersection of data engineering, AI/ML, and risk operations to safeguard the platform’s integrity and safety.

You will drive end-to-end detection logic, signal scoring, and dynamic thresholds across multiple data sources, while collaborating with engineering, risk, and trading teams to reduce false positives and improve

Qualifications

• 5–10 years of experience in real-time detection, fraud/risk analytics, or trade surveillance.
• Hands-on experience owning detection or anomaly systems.
• Proficiency in Python and SQL; experience with streaming data systems.

Responsibilities

• Own the end-to-end detection product: define detection logic, signal scoring frameworks, and dynamic thresholds across client behaviour, system anomalies, and financial irregularities.
• Extract actionable signals from large-scale, high-noise, multi-source data — trading logs, user activity, system metrics, and financial outcomes.
• Design and optimise real-time detection pipelines with low latency requirements (seconds‑level response for critical events).
• Develop and iterate on anomaly detection models, behavioural clustering, and pattern recognition systems; integrate hybrid rule‑based and ML approaches.
• Translate complex detection requirements into precise technical specifications for engineering teams; act as the bridge between detection logic and production systems.
• Partner cross‑functionally with data engineering, risk operations, trading, and infrastructure teams to ensure full coverage and system alignment.
• Drive reduction of false positives while maintaining high detection precision and coverage across key system and user activity.
