Опис вакансії

We’re looking for a Senior Node.js Backend Developer to join our team and help shape a global well-being platform. You’ll design scalable solutions, work with modern microservices on AWS and Serverless frameworks, and collaborate across teams to deliver impactful features. This is your chance to tackle complex challenges, modernize legacy systems, and contribute to a culture of innovation and growth.

About the project

The health app you’ll contribute to is a comprehensive well-being platform designed for companies worldwide. It’s the go-to resource for employees seeking support, guidance, and advice on challenges in their work and personal lives. Whether it’s reading an article on mental health, completing a financial assessment, or connecting with a counselor, the app has you covered.
It also offers fitness tracking, integrations, perks like gift cards, and social recognition features—all aimed at promoting employee well-being and fostering a positive workplace culture.

How we do it

Our team of 35+ backend developers is building and maintaining a large-scale, modern web infrastructure hosted on AWS, using technologies like Python, PHP, Node.js, Mongo, DynamoDB, and MySQL.
As our platform expands globally, we face exciting challenges like distributed data storage, performance optimization, and scaling. We work across the entire development lifecycle—designing solutions, writing and testing code, automating deployments, and collaborating with web, iOS, Android, QA, infrastructure, and product teams to deliver exceptional results.
We’re also migrating from a monolithic application to a microservices architecture using tools like the Serverless Framework and AWS services.
Our work environment is friendly and supportive, encouraging developers to learn, grow, and share ideas. We attend conferences, host team workshops, and explore new technologies to drive innovation and build a strong foundation for the future.

What we’re looking for

Technical skills matter, but what we value most is a positive attitude and a willingness to learn. Our backend team is looking for people who enjoy solving problems, building new things, and supporting their teammates. Strong communication, teamwork, and a knack for mentoring others are key to helping the whole team grow. If you’re excited about working with new technologies in a collaborative, supportive environment, this could be the perfect fit for you.
