Interested in working for a team of people completely redefining how fitness and health care work together? At Peerfit, we’re flipping wellness reimbursements on their head by connecting insurers’ and employers’ wellness dollars to popular fitness studios offering CrossFit, yoga, barre, boot camp, cycling, and more. If working with a team of innovative and driven people who are modernizing how people engage with wellness excites you, look no further than Peerfit.

As a senior backend software engineer you'll support the business as it undergoes extensive scaling this year. This will include:
Extending our JSON API to support platform features for Web, iOS, and Android
Building and supporting new inbound and outbound partner API integrations
Standardizing business operations that support account management and engagement of the Peerfit user experience through new technology and tools
Applying a domain driven design to the modeling of the application and adapt it to current business strategy and processes

You will be joining a growing backend team of polyglot developers who are working to bring the current system to its next tier of maturity. The ideal candidate should be prepared to continue to scale the platform's robustness through clean code and test coverage, enhance the adaptability and fault tolerance of the system, and help to coordinate key architecture and technology decisions.

We're seeking someone who is solution-oriented, pragmatic, and consensus-driven in their approach to rapidly building iterative software that solve real problems in our product and technical domains.

You will be responsible for managing, extending and scaling our core backend services and help influence our technical architecture with technologies that can support the business' continued growth. You will represent the backend in the delivery of new platform features through full-stack project teams. In addition, you will provide support to your backend peers through pair programming, code reviews, and team-wide continuous improvement.

You will also collaborate with the other functional areas that make up the Product team including Data, Frontend Web (React), Native mobile (Swift, Kotlin), and Infrastructure. Additionally, you will work with members of the business to understand objectives from first principles, capture requirements through user stories and journeys, and deliver solutions through a stakeholder-driven acceptance process.
