Growth Software Engineer

Role Overview

• 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.

Requirements

• Track record: You have strong software engineering experience in a fast-paced environment with real production constraints, ideally in a B2C product used by hundreds of thousands of users. You have shipped features end-to-end and taken full ownership of their outcomes.
• Builder's mindset: You love building things that move metrics. You are not just coding — you are thinking about the business impact of what you ship.
• Full-stack spirit: You are comfortable across the stack. You adapt to whatever layer the problem lives in — front, back, infra — without hesitation.
• Analytical skills: You are deeply data-driven. You instrument your code, design experiments, and use data to validate or kill your hypotheses.
• Fast learner: You are up to speed quickly on new domains, new markets, and new constraints. You are energized by unfamiliar territory, not slowed down by it.
• Problem solver: You bring creative, practical solutions to complex, ambiguous problems. You do not wait to be told what to build — you figure out what matters and go build it.
• Drive & ownership: You hold yourself accountable for outcomes, not just outputs. You care about whether your work actually moves the needle.
• Team player: You work closely with Product, Design, and Data. You communicate clearly, share context generously, and make the people around you faster.
• Language: You are fluent in English (written and spoken).
• Mindset: You have an entrepreneurial mindset, you like challenges, you welcome feedback and you love constantly learning and getting better.
