Algos Tech Lead, Transaction Monitoring

About the role

At Solidus Labs, we are shaping the financial markets of tomorrow by providing cutting-edge, real-time trade surveillance and transaction monitoring technology for regulated and crypto-native financial institutions. We protect investors, enhance transparency, and ensure regulatory compliance across traditional assets, prediction markets, and crypto.

We're hiring a Tech Lead to join our Algorithms team and own the Transaction Monitoring (TM) detection algorithms, product engineering effort end to end.

What you'll own :

• Lead, mentor, and grow the existing TM global engineering team - sprint delivery, code quality, on-call health.
• Own implementation of our offchain TM detection suite.
• Drive the build-out of on-chain TM - wallet-level and protocol-level monitoring, and the data pipelines behind it.
• Produce and defend both high-level and low-level design: system architecture, data models, detection logic, and threshold/tuning frameworks.
• Partner with Global Product on the on-chain roadmap, translating regulatory and customer requirements into deliverable engineering plans.
• Merging various patterns to re-use: You'll help shape that architecture and, over time, how engineering resources are shared across TM and TS.
• Work with compliance, customer success, and solutions teams on alert quality, false-positive reduction, and client tuning requests.

Requirements

What we're looking for

• 8+ years backend engineering experience, including 2+ years leading or tech-leading a team.
• Strong domain knowledge of the financial ecosystem - fintech, payments, banking or crypto - and a solid understanding of financial crime or compliance concepts.
• Genuinely hands-on: Strong data structures and algorithms fundamentals, a track record of high-performance concurrent code, and still reviewing PRs and debugging production.
• Proven design ownership at both levels - architecture decisions and detailed implementation design.
• Experience with high-throughput, low latency data systems: streaming (Kafka or similar), analytical stores (ClickHouse, Snowflake, or similar),and distributed batch processing.
• Clear written and verbal communication with non-engineering stakeholders.
• Experience with AI coding and using coding harnesses

Nice to have

• On-chain/blockchain data experience - chain indexing, wallet clustering, DeFi protocol mechanics.
• Exposure to trade surveillance or market abuse detection.
• Experience at a RegTech vendor or in a bank/exchange compliance technology function.

Benefits

Why join us?

You'll own a product line, not a component - with a team already in place, a clear regulatory driver, and a roadmap that expands into on-chain and market surveillance convergence.
