We’re partnered with a high-growth FinTech scale-up at the forefront of building next-generation market surveillance and risk monitoring technology. Backed by leading investors and trusted by global financial institutions, regulators, and crypto-native firms, they process trillions of market events daily to protect investors, detect manipulation, and ensure integrity across both traditional finance and digital asset markets.
As a Senior Software Engineer, you’ll play a key role in designing and scaling advanced systems and algorithms that safeguard some of the most dynamic and complex markets in the world. This is a chance to build high-performance, low-latency, and cloud-native systems while tackling challenges in fraud detection, data engineering, and market integrity.
What you’ll do
Design, implement, and optimise algorithms for detecting manipulation, fraud, and compliance breaches in real-time and batch data.
Build and scale high-volume data pipelines handling billions of daily events across distributed systems.
Work with cutting-edge tech including Java, Kafka, Spark, Kubernetes, Clickhouse, Snowflake, Redis.
Collaborate with quants, data scientists, and compliance experts to improve surveillance strategies.
Contribute to system architecture for low-latency monitoring and high-throughput processing.
Continuously improve data quality, reliability, and query optimisation at scale.
? What we’re looking for
5+ years’ experience in software engineering, ideally in financial markets, market surveillance, or large-scale data systems.
Strong skills in Java (or similar: Kotlin, C#, C++); Python is a plus.
Proven experience with real-time, low-latency systems and distributed data pipelines.
Hands-on with Kafka, Spark, K8s, Clickhouse, Snowflake, and modern data architectures.
Solid foundations in algorithms, system design, and optimisation.
Curious, proactive, and comfortable working in a fast-moving, scaling environment.
Why apply?
Fully remote role with global reach.
Up to £120k base + bonus + stock options.
Build mission-critical systems at the intersection of finance, crypto, and AI/ML-driven surveillance.
Work alongside world-class engineers, quants, and technologists shaping the future of market integrity.
