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.\nOur culture:\nWe have hubs in the Bay Area, NYC, Austin, Toronto, and São Paulo. However, we maintain a remote-first work culture. #WorkFromAnywhere\n\nWe hire talented, self-motivated individuals with extreme ownership and high growth orientation.\n\nWe 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.\n\nLocation:\nRemote - To be considered for this position, you must reside in the Eastern Time Zone to meet the needs of the team.\nAbout the Role:\nAs a frontend-focused Senior Software Engineer, you will own the design and delivery of the user-facing experiences at the heart of our AI products. Your primary focus is building polished, performant, production-grade interfaces in React and TypeScript. You'll also work in Go on the backend services and APIs that power those experiences, but that's a secondary part of the role. This is a high-autonomy, high-leadership position: you'll develop new features at scale, set the standard for how we build on the frontend, mentor the engineers around you, and use AI/agentic tooling (like Claude) to ship far faster than a traditional team would. The ideal candidate pairs exceptional frontend craft with the judgment to lead and the discipline to be relentlessly efficient with modern, AI-assisted workflows.\nWhat you'll be doing:\nDesign, build, and own user-facing features in React and TypeScript - polished, accessible, performant, and production-ready.\n\nSet the technical direction and quality bar for our frontend, and lift the people around you through mentorship and code review.\n\nUse AI and agentic development tools (such as Claude) fluently and effectively to move quickly, and help establish best practices for AI-assisted development across the team.\n\nDip into Go to build and extend the backend services and APIs behind your features when needed.\n\nCollaborate closely with business stakeholders to architect and implement new experiences from inception to delivery.\n\nContribute to product and technical roadmaps, and to the broader direction of the engineering team.\n\nCraft and maintain user-facing technical documentation that drives understanding and adoption of our products.\n\nPlay a pivotal role in shaping our engineering culture and ensuring high standards across the organization.\n\nWhat you'll need:\n7+ years of proven experience as a software engineer, with deep specialization in frontend development.\n\nExpert-level React and TypeScript, with a strong eye for UX, performance, and accessibility.\n\nDemonstrated fluency with AI and agentic coding tools (e.g., Claude), and a track record of using them to ship efficiently and raise your own throughput.\n\nLeadership experience: setting technical standards, mentoring engineers, and driving key technical decisions.\n\nA track record of shipping high-quality, production-grade frontend at scale.\n\nWorking proficiency in Go (or the ability to become productive in it quickly) for backend services - secondary to your frontend work.\n\nComfort with ambiguity and the ability to prioritize autonomously against business needs.\n\nCustomer-centric approach with strong empathy toward users.\n\nRelevant industry experience in fintech, fraud, compliance, risk, or regulated systems is preferred.\n\nProficient in English - from casual chats to formal reports.\n\nExposure to data tooling or pipelines is a nice-to-have, but not required.\n\nTechnologies we use:\nTypeScript (React + Node)\n\nGolang\n\nBigtable\n\nPostgres / PostgreSQL\n\nBigQuery\n\nPython\n\nJava\n\nTerraform\n\nBenefits we offer:\nGenerous compensation in cash and equity\n\nEarly exercise for all options, including pre-vested\n\nWork from anywhere: Remote-first Culture\n\nFlexible paid time off and Year-end break\n\nHealth insurance, dental, and vision coverage for employees and dependents - US and Canada specific\n\n4% matching in 401k / RRSP - US and Canada specific\n\nMacBook Pro delivered to your door\n\nOne-time stipend to set up a home office - desk, chair, screen, etc.\n\nMonthly meal stipend\n\nMonthly social meet-up stipend\n\nAnnual health and wellness stipend\n\nAnnual Learning stipend\n\nJoin a fast-growing company with world-class professionals from around the world.
