Job summary

Sardine is hiring a frontend-focused Senior Software Engineer to own the user-facing experiences in React and TypeScript, while partnering with Go for backend services as needed.

You will lead frontend direction, mentor engineers, and leverage AI-assisted tooling to accelerate delivery and quality. This remote-friendly role requires senior-level expertise and a strong user-centric mindset.

Qualifications

• 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.
• A track record of shipping high-quality, production-grade frontend at scale.
• Working proficiency in Go for backend services — secondary to frontend work.
• Comfort with ambiguity and the ability to prioritize autonomously against business needs.
• Customer-centric approach with strong empathy toward users.
• Relevant industry experience in fintech, fraud, compliance, risk, or regulated systems is preferred.
• Proficient in English — from casual chats to formal reports.
• Exposure to data tooling or pipelines is a nice-to-have, but not required.

Responsibilities

• Design, build, and own user-facing features in React and TypeScript — polished, accessible, performant, and production-ready.
• Set the technical direction and quality bar for our frontend, and mentor the team.
• Use AI and agentic development tools (Claude) to move quickly and establish best practices across the team.
• Dip into Go to build and extend the backend services and APIs behind your features when needed.
• Collaborate closely with business stakeholders to architect and implement new experiences from inception to delivery.
• Contribute to product and technical roadmaps, and to the broader direction of the engineering team.
• Craft and maintain user-facing technical documentation that drives adoption of our products.
• Shape engineering culture and ensure high standards across the organization.
