Senior Engineer, Web Full Time

About the Role 

Hungryroot is looking for a Sr. Frontend Software Engineer to join our growing Engineering Team. A successful Senior Frontend Software Engineer will partner with stakeholders to translate functional requirements into technical requirements and work with their team to bring that vision to life.

This individual will be responsible for facilitating changes to UI/UX and incorporating new systems from start to completion, which includes understanding the scope of projects, what is changing from the current experience, learning which APIs to use and when, verifying your work including testing and handling edge cases, and strong communication with other teams on blockers and progress.

Our most common type of project is running A/B test experiments with multiple variations of the same project running in parallel so we need to build and test each variation across multiple devices and viewports while preserving the pre-existing experience. In many cases, we have customers grandfathered into experiments so we need to maintain support for those experiences long-term.

Candidates should be experts in React, understand application design principles (back of the frontend; front of the frontend), modern and evolving CSS, have experience with animation, and be comfortable building high-fidelity UI/UX experiences for customers.

At Hungryroot, our Frontend team deploys continuously to Production after pull requests are approved and merged. You should be an expert with manually testing code before opening PRs up for peer review and comfortable writing unit tests with Vitest or similar libraries. Frontend engineers do not have a dedicated QA team, which is why attention to detail and testing is a critical part of this role.

• Contribute to enhancing code quality and reducing technical debt

Qualifications

• 5+ years working with React w/ Typescript
• Proficient with automation testing (Vitest, Playwright)
• Proficient with evolving CSS standards
• Experience with production-level frontend monitoring, error observability, and performance tuning (Sentry, Datadog, etc.)
