Senior Frontend Engineer

At Jaris, we’re redefining how financial services are delivered by building the modern infrastructure that powers embedded finance for platforms, processors, ISOs, and banks. Our platform streamlines everything from merchant onboarding and underwriting to bank account provisioning, compliance, and money movement — enabling our partners to launch financial products quickly and scale them confidently. By delivering the full stack of enablement tools and value-added financial services, we help our partners unlock new revenue streams and deliver better experiences to their customers. As we expand our impact, we're looking for curious, driven people who want to help modernize the financial ecosystem and support the small businesses that power the economy.

We’re looking for a Senior Frontend Engineer to craft intuitive, scalable web experiences and shape the future of our frontend architecture. You’ll work closely with product, design, and backend teams to deliver customer-facing apps, partner platforms, and internal tools — all while helping us transition to an NX-based monorepo to speed up development, improve testing, and enable code sharing

• Build and maintain engaging, accessible web apps in React + TypeScript.
• Lead adoption of our NX-based monorepo for faster builds and reusable code.
• Create shared components and tools that ensure consistent UX across apps.
• Own features from concept to release, including testing and monitoring.
• Improve reliability through strong unit, integration, and end-to-end tests.
• Collaborate on architecture decisions and keep us ahead of frontend trends

What Success looks Like:

• Ship high-quality features quickly and safely.
• Drive measurable improvements in build times, code structure, and CI workflows.
• Contribute to a culture of thoughtful code reviews and clear documentation.
• Strengthen collaboration across teams while improving developer experience.

What We’re Looking For:

• 5–7+ years building production-grade web applications.
• Strong skills in React, TypeScript, JavaScript (ES6+), HTML/CSS.
• Interest or experience in leveraging large language models (LLMs) to enhance developer productivity, automate workflows, or enrich user experiences.
• Experience with monorepo build systems (NX, Turborepo) and CI/CD workflows.
• Solid testing chops (Jest, Vitest, Playwright, Cypress).
• Great communicator who thrives in cross-functional teams.
• Able to work in our Burlingame, CA office three days/week.

Bonus Points: Shared component libraries, accessibility best practices, frontend observability, Node.js/Next.js, and a passion for improving developer workflows.
