At Upnova, we believe in unlocking the power of upselling for every eCommerce business. While upselling may seem like an old and unglamorous tactic, it holds tremendous potential—especially for small to medium-sized businesses that lack the resources of larger corporations. By leveraging smart, data-driven upsell strategies, we aim to help these businesses grow, increase their Average Order Value (AOV), and reinvest their profits to scale sustainably.

Our mission is to break the barriers that prevent e-commerce brands from fully utilizing upsell opportunities, transforming what’s been seen as “unsexy” into a powerful growth engine.


Responsibilities:

  • Develop and Optimize Upselling Experience: You will lead the development and optimization of our upselling experience, ensuring high performance and seamless integration into various e-commerce platforms.

  • Frontend and Backend Development: Utilize your strong expertise in React JS for frontend development and enhance our backend systems using modern technologies.

  • Leadership Opportunity: For ambitious candidates, there is the potential to grow into the CTO role, leading our technology team and shaping the future of our tech stack.


We're Looking For:

  • Over 5 years of extensive experience with React

  • A master of integrating AI into your coding workflow (Chatting with AI doesn’t count 😝)

  • Always keep up to date with the latest technologies in Frontend Development

  • Extensive experience in Animation in React (preferably with framer-motion)

  • Bonus: Experience in developing an AI app


Why Join Upnova?

Impactful Work: Make a tangible impact on eCommerce businesses globally, driving their growth through smart upselling strategies.

Competitive Compensation: Salary ranges between €3,000 to €5,000 per month, complemented by stock options that let you share in our success.

Ownership and Autonomy: Take full ownership of projects, with the freedom to innovate and influence key decisions.

Flexible Working Conditions: Benefit from flexible working hours, accommodating your personal and professional life balance.


Join Upnova to leverage your technical expertise in a role that offers substantial growth, significant impact, and the flexibility to balance work with your lifestyle. For more details, visit our website or reach out directly. We look forward to seeing what we can achieve together!
