🎯 What you will do
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 operate at the intersection of product and engineering to move the business forward at speed, within a dedicated cross-functional task force bringing together key members from Marketing, Data, Business, and Product.
- Growth experimentation: 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 quantify impact, iterate on what works, and kill what doesn't, fast.
- Engagement & product complexity: You will work on ambitious features like gamification, personalization, and cross-feature engagement to deepen user connection with Joko's increasingly complex product surface.
- AB testing & data-driven development: 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.
- Fast prototyping: You will move quickly, put prototypes in front of users, gather feedback, and iterate. You will thrive on short cycles and learning loops.
- Cross-functional collaboration: You will be the natural bridge between business, product, and technical stakeholders. You will translate business challenges into engineering solutions, surface technical constraints that shape product decisions, and ensure alignment across teams so that growth efforts move fast without friction.
- International expansion: 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.
👀 Who we're looking for
- Experience: You have at least 3 years of software engineering experience in a fast-paced environment, ideally in a B2C product.
- Track record: You've worked 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.
