Senior Software Engineer - Pricing & Promotion (m/f/d)

Launched in 2021 with a simple yet bold mission, Flink set out to give people back their most valuable resource: time. We didn't just join the quick commerce race, we defined its potential. By enabling customers to order from a curated selection of over 3,000 groceries and household essentials through our user-centric app, we deliver what people need in minutes. We have fundamentally shifted the retail landscape across Germany and the Netherlands, while embedding sustainability into our core through an all-electric delivery fleet, recyclable packaging, and a focus on reducing food waste.

Today, Flink has evolved from a disruptive startup into a resilient and sustainable powerhouse. In an industry defined by rapid change, we’ve mastered the balance of hyper-efficiency and massive scale. With a network of around 160 hubs, we now bring the Flink experience to more than 22 million people, making us an integral part of the urban infrastructure. This impact is driven by a dedicated team of more than 10,000 colleagues, including a fully employed rider fleet that serves as the backbone of our operations. By generating over €550m in revenue in 2025, we have proven that our model is not only desirable but financially formidable.

In your role as Senior Software Engineer - Pricing & Promotion (m/f/d), you will be one of our first hires into our new RevTech domain, architecting and building the future of our pricing and promotion engine. This is not just a coding role; you will be a technical leader, strategist, and instrumental in pioneering how pricing is done in real time.
