• Perform full-stack development including front end, business logic, and data access layers. • Responsible for the entire development lifecycle from planning to release and support • Actively contribute to software architecture decisions, design strategies, and code reviews to ensure high-quality, scalable, and maintainable solutions • Collaborate closely with development team members and stakeholders • Maintain high standards, attention to detail, accuracy and completeness

• Lead the design and development of scalable solutions. • Collaborate with cross-functional teams in problem-solving activities. • Ensure high-quality deliverables that align with client expectations. • Create and maintain the product backlog by translating user stories into architectural tasks. • Communicate effectively with stakeholders on technical solutions.

• 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
