Senior Backend Developer, SCM Tech Fulfillment

S'more about the team

The Production Scheduling Technology team builds and maintains the platform that powers how HelloFresh plans, sequences, and optimizes production across our operations. Our team has developed the first iteration of the next-generation internal system with a planning engine that now automates the end-to-end planning process – a system with deep impact on how millions of meals move through our network.

As we continue evolving this system, extending its capabilities, and preparing for expansion, we are looking for a Senior Software Engineer with strong backend experience, a talent for turning complex logic into clean, reliable systems, and enough full-stack fluency to support and enhance our internal application.

Above all, we are looking for people 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.

Lettuce share what this role will be responsible for

• Build, enhance, and co-own the Python-based algorithmic engine that drives automated planning, including deterministic logic and constraint-based components
• Design, develop, and maintain backend services using FastAPI, ensuring scalable, reliable API interactions with our internal application
• Work end-to-end across architecture, implementation, deployment, and operations within our modern technology ecosystem (EKS, RDS, S3, ElastiCache, Glue, etc.)
• Collaborate closely with engineers, analysts, and planners to translate domain knowledge into robust, maintainable system logic
• Contribute to the evolution of the platform toward event-driven patterns using technologies like Kafka
• Support frontend needs for our internal React application, ensuring seamless integration between FE and BE layers
• Improve reliability through automated testing, performance tuning, and thoughtful system design
• Guide as well as learn through pairing, design discussions, and knowledge sharing to help strengthen collective ownership across a strong, team-first environment
• Participate in shaping the future direction of an advanced system
• Work beyond your specialization when the problem demands it. Your specialization is your anchor, not your boundary.
• Operate what you build. You instrument, monitor, and improve your systems in production. Shipping is the beginning of the learning cycle, not the end

Sound a-peeling? Here's what we're looking for

• Hands-on experience working with AI tooling (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.
• Strong software engineering experience with a focus on backend development and Python as the primary language
• Experience designing and building systems with complex business logic, including deterministic, constraint-based optimizers, and MIP solvers
• Hands-on experience building production-grade APIs with FastAPI or similar modern frameworks
• Solid knowledge and experience with relational databases and comfortable working with data across various data systems (PostgreSQL, Snowflake, S3)
• Experience with event-driven architecture and messaging technologies
• Working knowledge of cloud environments, containerization, and orchestration (AWS, Docker, Airflow)
• Experience contributing to or designing scalable architecture for internal tools or operational platforms
• Full-stack capability with React or another modern FE framework — enough to support and enhance application
• Strong communication skills and a proactive, collaborative approach to working with engineers, analysts, planners, and product partners
• Comfort working through ambiguity and contributing clarity through simple, pragmatic design choices
• A mindset of continuous learning, knowledge sharing, and improving the systems
• Nice to have: Bachelor’s or Master’s degree in Computer Science, Engineering or related field
• Nice to have: Experience in Fulfillment, Logistics, Supply Chain, Production, or related field working with physical goods
• You take full ownership. You have a bias to ship. You finish the last twenty percent.
• You have product sense and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.
