• As a Growth Software Engineer, you will be the driving force behind scaling Joko's user and business growth through code. • You will work hand-in-hand with the Product team, iterating fast on high-impact levers — acquisition, retention, engagement — across France and our international expansion, starting with the US. • You will design, build, and ship experiments across the full user journey — from onboarding to retention — to drive significant impact on key growth metrics. • You will work on ambitious features like gamification, personalization, and cross-feature engagement to deepen user connection with Joko's increasingly complex product surface. • You will build and run AB tests at scale, instrument features for measurement, and partner closely with the Data team to make every decision evidence-based. • You will move quickly, put prototypes in front of users, gather feedback, and iterate. • You will translate business challenges into engineering solutions, surface technical constraints that shape product decisions, and ensure alignment across teams to fasten growth efforts. • Depending on priorities, you may also play a role in Joko's expansion into new markets, adapting the product to local contexts and helping our infrastructure scale across geographies.

• Own product areas end-to-end, shaping both the problems we tackle and how we solve them • Often start from a blank slate, and iterate based on data • Make pragmatic, data-driven tradeoffs between speed, quality, user experience, and scalability • Develop and communicate product opinions backed by evidence • Help establish patterns and norms for product-oriented engineering

• Design and develop internal software tools, services, and frameworks that improve the developer experience • Work with engineering teams to gather requirements and feedback for developer tools • Improve and maintain our CI/CD pipeline code and infrastructure • Contribute to the architecture of our developer platform by evaluating new technologies • Mentor and guide other software engineers in using DevX tools • Ensure all DevX solutions are well-documented, maintainable, and secure • Partner with engineering teams to define and enforce AI standards within the developer ecosystem

• codes software applications based on business requirements • standardizes the quality assurance procedure for software • oversees testing and debugging and develops fixes • researches complaints and makes necessary adjustments and/or recommendations to resolve complex software related issues • understands department, segment, and organizational strategy and operating objectives • makes decisions regarding own work methods, occasionally in ambiguous situations
