About Sardine
Sardine is an agentic risk platform for fighting financial crime, unifying data across risk teams to stop fraud in real time, prevent AI-driven attacks, and automate fraud and AML operations.

Customers include FIS, GoDaddy, Intuit, Edward Jones, ZoomInfo, and Checkout.com.
About the Role
As a frontend-focused Senior Software Engineer, you will own the design and delivery of user-facing experiences at the heart of Sardine's AI products. You will build polished, performant, production-grade interfaces in React and TypeScript, and also work in Go on backend services and APIs (secondary). This is a high-autonomy, high-leadership position: you'll develop new features at scale, set frontend standards, mentor engineers, and use AI/agentic tooling (like Claude) to ship efficiently.
What You'll Be Doing
- Design, build, and own user-facing features in React and TypeScript — polished, accessible, performant, and production-ready.
- Set technical direction and quality bar for the frontend; mentor engineers through code review.
- Use AI and agentic development tools (such as Claude) fluently to move quickly and establish best practices.
- Dip into Go to build and extend backend services and APIs when needed.
- Collaborate with business stakeholders to architect and implement new experiences from inception to delivery.
- Contribute to product and technical roadmaps and the broader engineering direction.
- Craft and maintain user-facing technical documentation.
- Play a pivotal role in shaping engineering culture and standards.
What You'll Need
- 7+ years of proven experience as a software engineer, with deep specialization in frontend development.
- Expert-level React and TypeScript, with a strong eye for UX, performance, and accessibility.
- Demonstrated fluency with AI and agentic coding tools (e.g., Claude) and a track record of using them to ship efficiently.
- Leadership experience: setting technical standards, mentoring engineers, and driving key technical decisions.
- Track record of shipping high-quality, production-grade frontend at scale.
- Working proficiency in Go (or ability to become productive quickly) for backend services — secondary to frontend work.
- Comfort with ambiguity and ability to prioritize autonomously.
- Customer-centric approach with strong empathy toward users.
- Relevant industry experience in fintech, fraud, compliance, risk, or regulated systems is preferred.
- Proficient in English.
- Exposure to data tooling or pipelines is a nice-to-have, but not required.
