Senior Python Developer

Brainence has spent 9+ years building first-class products — and the teams behind them. Over 50 startups and enterprises have trusted us to launch MVPs, scale engineering teams, and deliver products that perform in the real world. Our playground spans healthcare, edtech, real estate, retail, construction, logistics, insurance, and more.

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.

Our team of 35+ backend developers are building and maintaining a modern, large-scale web infrastructure hosted on AWS. We use a number of languages and technologies including Python, PHP, Node.JS, Mongo, DynamoDB and MySQL.

Our platform is expanding globally, and with this expansion comes new challenges such as distributed data storage, and processing and performance improvements.

Our team works at every stage of the software development life cycle — designing solutions, writing and testing code, and automating deployments. They also collaborate with our web, iOS, Android, QA, infra and product teams to deliver for our customers and users.

As well as building new features and functionality, we are migrating our original monolithic application to the micro-services world using modern technologies like Serverless Framework and AWS Services.

Our team likes to foster a friendly and welcoming work environment where developers can learn and grow. Team members attend conferences and meet-ups, and we regularly run team workshops to discuss and share new ideas and technologies. This helps us drive innovation and develop an effective basis for future developments.

While technical skills are important, they are not the main priority. The backend development team is looking for positive individuals who are eager to learn, support their teammates, solve problems, and build new solutions. We value strong communication, teamwork, and a willingness to mentor others so the entire team can grow together. If you want to work with modern technologies in a collaborative and supportive environment, this opportunity will be a great fit for you.
