Work with HelloFresh in Warsaw and its HelloTech organisation, HelloFresh’s global technology backbone with more than 1000 people, building the digital products that power our end-to-end food experience. From meal kits and ready-to-eat meals to specialty offerings like pet food and premium meat & seafood, HelloTech creates the platforms that bring tailored food solutions to millions of customers every month.

Our subscription-based, direct-to-consumer model relies on technology at every step, from customer-facing apps and personalization logic to pricing, forecasting, supply chain optimization, and initiatives that help reduce food waste. While our brands operate independently to serve distinct customer needs, they are united by shared platforms, data, and operational excellence built by HelloTech.

HelloTech works in autonomous, cross-functional alliances, each owning a specific product or domain end to end. By working with our Warsaw office, you will help shape scalable, data-driven products used across our markets, working with a modern tech stack and international teams to continuously improve how people discover, order, and enjoy HelloFresh’s products, today and in the future.

About the role: What's in the Box

You will work with a cross-functional team responsible for how HelloFresh communicates with its customers at scale. The project involves supporting backend-driven, AI-powered systems that automate campaign execution end-to-end — from campaign configuration and content generation to validation, quality checks, and orchestration across channels such as email, SMS, and push.

Working with large-scale data and machine-learning–driven decisioning, you will support the design and operation of reliable, scalable services that reduce manual effort while improving speed, consistency, and customer relevance.

At HelloTech, flexibility and cross-functional collaboration are core to how we work. While this role is aligned to a specific Alliance, strong candidates may also be considered for opportunities across different teams or projects.

What you’ll do: The Recipe

Collaborate within an autonomous, cross-functional agile team of 6–10 people, working closely with Product Owners, Frontend Engineers, Data Engineers, and Business Intelligence teams to deliver impactful solutions.
Work on the architecture, design, development, deployment, and operations of our microservices, autonomously driving complex business challenges from conception to resolution.
Build and maintain robust event-driven systems using state-of-the-art technologies.
Leverage modern AI tools and DevOps practices to enhance productivity, strategically utilizing methodologies like vibe coding and pair programming.
Support colleagues by sharing practical knowledge, trends, and technical insights, contributing to an environment where technical perspectives are valued.

What you’ll bring: The Ingredients

Expertise in Python development, covering the full lifecycle from unit, integration, and functional testing to application tuning, profiling, and continuous integration.
Solid background in event-driven microservices architecture, utilizing tools such as RabbitMQ or Kafka.
Proficiency with data storage, including relational databases like PostgreSQL and object stores like AWS S3.
Strong agile mindset, with a focus on lean thinking, quick iterations, and continuous delivery in a fast-paced environment.
Ability to utilize monitoring solutions like Prometheus, Grafana, or Datadog to ensure system health.
Experience integrating external systems, such as third-party vendors, APIs, marketing platforms, or messaging services, is a strong plus.
Curiosity and drive, seeking to continuously develop yourself, learn from peers, and act as an ambassador for AI mentality within the team.
Solid hands-on experience working with AI coding agents (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents as thought partners to onboard on unfamiliar codebases and navigate new areas of the code with confidence. You have a practical sense of how the context you provide to AI tools - specifications, constraints, examples - shapes output quality, and a developing awareness of how agentic outputs can fail, with growing habits around verifying, testing, and setting boundaries on AI-generated work.

Above all, we are looking for individuals who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences! So even if you don’t “tick all the boxes” but think you’d thrive in this role, we would really like to learn more about you.

What we offer: The Toppings

Global collaboration at scale: Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.
Technology with real-world impact: Build and operate modern systems at global scale, supporting 6+ millions of customers and complex supply chain operations.
Technical/Product/Design leadership: Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.
End-to-end development/delivery: Drive decisions from problem definition to production, improving systems and enabling long-term scalability.
Access to workspace at Warsaw Centre Point. The hub offers modern facilities including showers, breakout zones, outdoor space, cycle parking, and refreshments (coffee, soft drinks, and fruit).
