Fullstack Engineer, Investigator Tools

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.

About the role:

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 build out data-intensive applications, including advanced graph systems used to uncover complex fraud rings. 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.

Translate complexity to usability: Build out complex technical systems into intuitive, user-friendly interfaces.

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.
