Senior Backend Product Engineer - Python and/or Go (all genders)

<p>At HelloFresh, the goal is to change the way people eat forever by delivering high-quality food across 18 countries and 3 continents. As a global food solutions group and the world&#39;s leading meal kit provider, the portfolio includes HelloFresh, Green Chef, EveryPlate, Chefs Plate, Factor_, and Youfoodz.</p> <p>Engaging with HelloFresh in Warsaw means collaborating with HelloTech—a global technology division of over 1,000 people powering an end-to-end food ecosystem. From digital personalization and forecasting to supply chain optimization and food waste reduction, technology drives every step of this direct-to-consumer model.<br><br></p> <h2><strong>About the Role: What&#39;s in the Box</strong></h2> <p>HelloTech operates in autonomous, cross-functional alliances, each holding accountability for a specific product domain end to end. The service provider will join an assigned squad, with the flexibility to transition between teams and projects as technical objectives and business priorities evolve.</p> <p>Several technical domains are actively engaging providers. Projects will be aligned based on individual strengths and expertise during the process. Key technical domains include:</p> <ul> <li><strong>Marketing Customer Profile squad:</strong> Builds AI-powered backend systems that automate campaign execution end-to-end, from content generation and validation to multi-channel delivery across email, SMS, and push.</li> <li><strong>Conversions Tribe:</strong> supporting the &quot;Reachable Audience&quot; and Personalization initiatives. The mission is to build the systems that power customized user journeys at scale.</li> </ul> <p>Across all domains, the technical profile consists of highly available, event-driven distributed systems serving global architectures. This role does not include people management responsibilities.</p> <h2><strong>What You’ll Do: The Recipe</strong></h2> <p>At HelloFresh we are moving away from a model where software developers just execute tickets toward one where product engineers are trusted to own customer problems. A Product Engineer takes a problem, forms a point of view, validates it with customers and data, and ships it using AI as a force multiplier.</p> <ul> <li><strong>Take the technical lead on backend-heavy product problems</strong>, designing, building and operating the services and systems needed to deliver them reliably at scale under a full DevOps model..</li> <li><strong>Build event-driven systems</strong> utilizing messaging technologies such as Kafka, RabbitMQ, or AWS SQS/SNS, and expose data via clean REST and gRPC interfaces.</li> <li><strong>Work extensively</strong> with Docker, container orchestration via Kubernetes, and CI/CD automated deployment pipelines.</li> <li><strong>Maintain a strong commitment to testing</strong>, executing robust test suites stretching from unit tests through to full end-to-end coverage.</li> <li><strong>Collaborate closely</strong> within cross-functional agile teams including product leads, frontend engineers, designers, and data teams.</li> <li><strong>Provide technical guidance</strong> and support to surrounding team members, actively participating in code and architecture reviews.</li> <li><strong>Leverage modern AI tools</strong> and workflows (e.g., Claude, Cursor) as a standardized component of engineering delivery to increase productivity.</li> <li><strong>Work beyond your specialization when the problem demands it</strong>. Your specialization is your anchor, not your boundary.</li> <li><strong>Operate what you build</strong>. You instrument, monitor, and improve your systems in production. Shipping is the beginning of the learning cycle, not the end.</li> </ul> <h2><strong>What You’ll Bring: The Ingredients</strong></h2> <ul> <li><strong>Hands-on experience working with AI tooling </strong>(e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.</li> <li><strong>Strong fluency in Go or Python and hands on experience building distributed systems in production</strong>: event-driven and asynchronous flows, clear service contracts, and designing for partial failure. High proficiency in one stack is required, with a willingness to expand technical knowledge into Go. You operate what you build, including its observability and data layer.</li> <li><strong>Solid experience</strong> building, deploying, and operating critical backend services in a production environment.</li> <li><strong>Technical comfort</strong> navigating distributed systems, messaging queues, containerization, and modern deployment infrastructure.</li> <li><strong>Strong software engineering instincts</strong>, including practical application of design methodologies like TDD, BDD, or DDD, and the ability to make sensible technical trade-offs.</li> <li><strong>Excellent communication capabilities</strong> to operate effectively inside an international, multi-disciplinary technical environment.</li> <li><strong>You take full ownership.</strong> You have a bias to ship. You finish the last twenty percent.&nbsp;</li> <li><strong>You have product sense</strong> and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.</li> </ul> <h2><strong>What We Offer: The Toppings</strong></h2> <ul> <li><strong>Global collaboration at scale:</strong> Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.</li> <li><strong>Technology with real-world impact:</strong> Build and operate modern systems at global scale, supporting millions of customers and complex supply chain operations.</li> <li><strong>Technical/Product/Design leadership:</strong> Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.</li> <li><strong>End-to-end development/delivery:</strong> Drive decisions from problem definition to production, improving systems and enabling long-term scalability.</li> <li><strong>Access to workspace at Warsaw centre:</strong> The hub offers modern facilities including showers, breakout zones, outdoor space, cycle parking, and refreshments (coffee, soft drinks, and fruit).</li> </ul> <p>#ENGINEERING</p>
