You will report to the Director of Engineering and work alongside a scrum team. Our team is kind, supportive, and has a strong collaborative dynamic. We believe in helping each other grow and develop professionally to create great products that make a real difference in people's lives.

Job Description

We are seeking an exceptional Senior Data-Backend Engineer with deep Python expertise to join our mission of improving lives through technology-enabled healthcare. In this role, you will architect, build, and maintain the critical backend systems that power our health coaching platform, directly impacting the care we provide to patients with chronic conditions.

As a Senior Data-Backend Engineer at Kannact, you'll be at the intersection of healthcare and technology, working with a modern tech stack including Python (FastAPI), Java (SpringBoot), and Node.js (Fastify) in a microservices architecture hosted on AWS and orchestrated with Kubernetes.

The ideal candidate is not just a technical expert but also a problem solver who takes ownership of projects from conception to production. You'll collaborate with product managers, designers, and other engineers to understand requirements, architect solutions, and implement robust, scalable systems. You should be comfortable diving into infrastructure code with Terraform, troubleshooting Kubernetes issues, and optimizing database performance across PostgreSQL and ClickHouse.

This role offers the opportunity to apply your technical expertise to meaningful work that directly improves people's health outcomes. You'll be empowered to drive technical decisions, mentor junior engineers, and contribute to the evolution of our platform while working in a supportive, remote-first environment that values work-life balance.
