Fully Remote | Up to £120k Base + Bonus + Stock Options

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.
