Descripción del empleo

Who we are:

Sardine is the leading agentic risk platform for fighting financial crime. Our integrated solution unifies data across risk teams to help organizations stop fraud in real time, prevent AI-driven attacks, and automate fraud and AML operations. Sardine’s platform is strengthened by one of the fastest-growing fraud consortiums in the market, spanning more than 6 billion profiled devices, 800 million consumers, and 3 million businesses worldwide. Leading companies including FIS, GoDaddy, Intuit, Edward Jones, ZoomInfo, and Checkout.com rely on Sardine to secure and grow trust in their products.

Our culture:

• We hire talented, self-motivated individuals with extreme ownership and high growth orientation.

• We value performance and not hours worked. We believe you shouldn't have to miss your family dinner, your kid's school play, friends get-together, or doctor's appointments for the sake of adhering to an arbitrary work schedule.

• We're a remote-first team spread across time zones, so no office to report to - work from wherever helps you do your best work. Just a couple of things to keep in mind: pay is based on where you're located, and you'll need to keep a home base in the country you're hired in. So while we love the "coffee shop today, mountains tomorrow" life, this isn't a passport-optional, work-from-anywhere-on-Earth kind of remote - think flexible within your country, not borderless.

Location:

• Remote - Germany

• Ensure system health: Proactively diagnose, triage, and resolve bugs while writing highly efficient and performant code.

What you’ll need:

• Core technical stack: Extensive experience writing efficient, production-ready code in TypeScript, Node.js, React, Go and other server programming languages.

• Scale and data expertise: Proven experience working with data-intensive applications, complex workflows, and big data at scale.

• Pipeline proficiency: Deep background in technical data modeling and building robust production data pipelines.

• High-growth adaptability: The ability to thrive, execute, and deliver consistently in a fast-paced, high-growth startup environment.

• Independent execution: A proven track record of taking extreme ownership of ambiguous problems and independently turning them into polished, scalable features.
