About the role

- The primary development stack involves Python (using the Django framework) for the backend and JavaScript/TypeScript (with React) for the frontend.
- Build features that gracefully integrate with internal/external APIs and services.
- Take end-to-end ownership of features, from initial technical design and planning through to production deployment, ensuring measurable business impact.
- Author dependable, highly tested code, utilizing tools like pytest, Jest with React Testing Library, Storybook, and Cypress for complete coverage.
- Ensure platform performance and stability by actively leveraging observability tools.
- Promote engineering excellence by creating high-quality, practical documentation.
- Our infrastructure is entirely hosted on AWS; you will work hands-on with services such as Kubernetes, Docker, PostgreSQL, Redis, SQS, SNS, and S3.
- Partner closely with Product Managers, Designers, QA, and other engineers to translate product vision into effective, delivered value.
- Implement new features as controlled A/B experiments and rigorously measure their impact.
- Scale and maintain the system responsible for delivering email and push notifications to our user base.
Requirements
- Demonstrated expertise with Python and robust backend web frameworks (we use Django, but all experience welcome)
- Deep proficiency in React, modern JavaScript/TypeScript, HTML, and CSS fundamentals.

- Ability to produce clear, maintainable, and resilient code.
- Exceptional knowledge of automated testing methodologies, particularly unit testing, is required to guarantee production quality.
