above all
own the success of the product. You'll have the opportunity to have your hands in everything, from the data model to stylesheets, from concepts to launches, from process to implementation - and everything in between.

Continually Improving. Building on your experience, you are constantly looking to fill gaps, iterate, and level up.

Experience developing complex React applications, with expertise beyond static websites. You should have a deep understanding of React architecture, state management, and performance optimization.
A deep understanding of the React component lifecycle.
Expert knowledge of React's state management ecosystem - from Context and reducers to modern alternatives.
A strong knowledge and love for all things CSS and how to bend it - using both vanilla CSS and CSS-in-JS.
Taste! We often don't have pixel-perfect mockups, so we'll be relying on some of your great ideas to make things easy to use and look amazing. You love to apply just the right amount of UI animation to give your work that extra layer of polish.
A desire to iterate and improve your UI until it's the best it can be, including egoless participation in collaborative design reviews & iterations.
Bonus points if you have experience with…
Motion.dev (formerly Framer Motion).
Cross-client email design and understanding differences in HTML layout and compatibility issues for various email clients.

As a fully remote team of sharp, collaborative, and entrepreneurial individuals, we are dedicated to redefining the way healthcare workers and facilities work together to provide for patients. We are looking for passionate and skilled professionals to join our team and help us take on tough challenges in this fast-expanding healthcare industry segment.
Join us in our mission to transform the healthcare staffing industry and improve patient lives!
The Role
At Medely, we're transforming how healthcare professionals and facilities connect: faster, smarter, and at scale. Every experience we build helps nurses, clinicians, and hospitals focus less on logistics and more on care.
As our Staff Front End Engineer, you'll lead the front end vision for one of our core product teams. You'll partner with backend and mobile engineers to design elegant, performant, and scalable user experiences that power both sides of our marketplace. From architecture decisions to mentoring engineers, you'll shape how healthcare staffing feels and functions in the modern era.
The Impact You'll Make:
Act as the front end technical lead for cross-functional, agile teams building high-impact web applications.
Drive architecture decisions and code standards to ensure scalability, maintainability, and performance.
Collaborate with product, design, and backend partners to translate ideas into delightful, accessible, and performant interfaces.

Proven experience leading or architecting complex, interactive applications end-to-end.
Passion for design systems, performance optimization, and crafting exceptional user experiences.
Track record of mentoring engineers and improving team culture and process.
Collaborative mindset - you're equally comfortable whiteboarding solutions or rolling up your sleeves to ship them.
Awareness of scalability and performance considerations across browsers and devices.
BS/BA in Computer Science or related technical field (or equivalent practical experience).
What Will Set You Apart
You think beyond the code. You care about
how
things are built and
why
they matter to the user.
You've owned complex, high-traffic web applications and made measurable improvements to performance, scalability, or developer experience.
You have strong opinions, loosely held: you can articulate architectural decisions clearly but stay open to new ideas.
You find joy in details: accessibility, animation timing, responsiveness - the subtle things that turn a good UI into a
great
one.
Why Medely: Benefits & Perks
Competitive Compensation: Based on experience and performance
Long-term Incentives: 401k
Healthcare Benefits: Full suite of benefits including medical, dental, and vision insurance
Flexibility: We believe that work/life balance is important, so we offer flexible and unlimited PTO
Paid parental leave
Purpose: Join a growing mission-oriented startup that is modernizing the healthcare industry nationally!
Ownership: Drive meaningful business impact on a team you'll help build and define!
Remote: Work in a digital environment with all the tools to achieve your work as though you were in the office!
We're an equal opportunity employer to all. We interview and hire applicants of all backgrounds, orientations, expressions, and identities.
Work location is flexible if approved by Medely.
