The role

What you'll do
- Deliver new product capabilities from data layer through server logic to user interface.
- Create and refine AI-powered agent functionality within the product.
- Redesign and take responsibility for central product areas such as user onboarding.
- Support customers by email, chat and live calls, troubleshooting problems and learning how the product gets used.
- Contribute to establishing how the team plans and ships product work.
Requirements
What we're looking for
- At least 4 years of professional software engineering experience.
- Strong skills in Python, with solid experience in React and cloud infrastructure on AWS.
