Join a profitable European consumer tech scale-up building the future of online shopping.

The product already helps millions of users shop smarter, save money and make better purchasing decisions across thousands of merchants.

The company is a certified B Corp, has reached profitability in its core market, and is now scaling internationally with a strong focus on the US.

The product suite spans cashback, automatic coupons, price alerts, carbon tracking, AI-powered shopping assistance and large-scale e-commerce data.

As a Senior Software Engineer, you will work on high-impact product and technical challenges across the stack.

This is not a narrow backend-only or frontend-only role. The team is looking for versatile engineers able to take ownership from product idea and technical design to production deployment, monitoring and iteration.

You may contribute to:

• User-facing product features reshaping the online shopping experience
• AI-powered shopping assistant initiatives helping users find products by price, quality and impact
• Scalable algorithms and systems extracting, structuring and leveraging massive quantities of e-commerce data
• Search, recommendation, data-heavy or automation features
• Internal tools, customer support stack, fraud detection mechanisms or AI assistants
• Cross-functional projects with Product, Data and Operations

The official role is intentionally broad: the company wants versatile engineers, not profiles locked into one narrow language, framework or layer.

• Full-stack software engineering across product and operations use cases
• AI-powered assistants, automation and product intelligence
• Large-scale e-commerce data extraction, structuring and exploitation
• Scalable algorithms, search/recommendation-like problems and data-heavy product features
• Production-grade systems with deployment, monitoring, maintainability and impact measurement

• Design and build robust software architectures across the stack
• Translate product or operational needs into reliable, production-grade systems
• Take ownership from idea to deployment and impact monitoring
• Explore complex and sometimes undefined technical problems
• Work closely with Product and Data teams to measure and improve impact
• Provide technical leadership through specs, code reviews and technical discussions

We are looking for a strong senior software engineer with a broad technical range, strong ownership and a genuine product mindset.

You may be a strong fit if you have:

• Strong senior software engineering fundamentals and production experience
• Experience building, shipping and improving products end-to-end
• Full-stack spirit: ability to work across several parts of the stack, not only one narrow layer
• Builder mindset and curiosity for user/business impact
• Fast learner comfortable with new technologies, frameworks and ambiguous problems
• Strong problem-solving skills with pragmatic technical judgment
• Clear communication, humility, feedback culture and team-player mindset
• Strong written and spoken English; French is not required

• Top-market compensation and equity for everyone
• Flexible remote: Paris employees can choose office or home with no constraints
• Coworking access and budget for employees living elsewhere
• Work from anywhere from most countries in the world up to 3 months per year
• Half-day each week dedicated to leveling up with AI: exploring tools, iterating and sharpening skills
• Yearly offsite in strong locations, plus team-building events and monthly in-person gatherings
• ClassPass contribution
• 8-week leave paid 100% for the second parent
