## Description

**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.

As a Full Stack Engineer at Sardine, you will bridge the gap between complex technical backend systems and user-friendly interfaces to help us stop fraud in its tracks. This is a dynamic, high-impact role. On average, you will be working 60% on backend development and 40% on frontend development but are willing to help out wherever is needed.

You will own features end-to-end at a massive scale, ultimately empowering fraud analysts to uncover and investigate suspicious transactions faster than ever before.

**Build fraud-fighting tools:** Develop and optimize advanced graph systems to visualize fraud rings, and build performant search tools that help analysts rapidly identify suspicious transactions.
**Collaborate cross-functionally:** Work tightly with Design, Data, Product, and Account Management teams to align engineering output with business and user needs.
**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.
