Role

Who you are

7+ years of software engineering experience, with a proven track record operating at a Staff, Principal, or Lead Architect level

What the job involves

You will serve as the technical steward and platform architect for both our Consumer Fraud and Business Fraud engineering teams
This position involves driving technical strategy, optimizing mission-critical infrastructure, mentoring engineers, and assuming broad ownership of a platform that processes massive volumes of data in real-time
Act as the overarching technical leader for multiple teams, partnering with stakeholders to unify platform strategy
Architect, design, and optimize ultra-low-latency backend services and a high-throughput rules engine
Design optimal data access patterns, partitioning strategies, and caching layers across our complex, multi-cloud database ecosystem
Develop robust pipelines for massive parallel execution of real-time feature computations and aggregations
Play a pivotal role in shaping engineering culture, mentoring senior engineers, and driving high technical standards from conception to delivery

Our take

Identity and payment fraud is one of the biggest dangers facing online businesses. Sardine is setting out to solve this problem by building the first zero-day fraud prevention technology.

Sardine's technology traces intrinsic behaviour patterns to identify so-called "bad actors" online, and detects fraudsters using machine-learned fraud scores and user behavior biometrics.

The company calls itself the world's first FaaS (Fraud Detection as a Service), and its solutions are already drawing business from next-gen crypto and financial service institutions. Onboarding these institutions and scaling its customer base at pace will ensure that Sardine maintains its frontrunner position.
