Senior Frontend Engineer - Fintech, Card at Engine — Remote

### About Engine

## The Role

We're looking for a Senior Frontend Engineer to join the Card team and help shape that next chapter. This isn't a "here's a ticket, go build it" role. You'll work closely with Product and Design to identify what's missing, what could be better, and how to build it — then execute with high quality and speed.

## What You'll Do

• Build new features across the Card platform: Trends & Insights, engagement/recognition improvements, points expiration, and off-platform redemption
• Own frontend work end-to-end — from design collaboration to testing and deployment Become the subject-matter expert for frontend code
• Improve test automation coverage using Playwright
• Instrument observability and A/B testing to understand what's working and surface gaps
• Contribute ideas proactively: what's missing, what should be improved, how to raise the quality bar

## What We're Looking For

• Strong React experience, with the ability to build modular, reusable components
• Product mindset — you don't wait to be told what to build; you identify gaps and bring proposals
• Familiarity with Playwright or a comparable E2E test automation framework
• Hands-on with AI-assisted development (Cursor, Claude, or equivalent) — our entire codebase is written with AI tooling
• Experience with A/B testing tools (e.g., Amplitude) and frontend observability (e.g., Datadog)

Nice to Have:

• Track record of leading features end-to-end with Product, Design, and backend engineers
• Experience writing technical documents or planning bug-bashes
