The role

The Fulfillment Planning 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 application 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 You

You will...

• 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

You have.....

• 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

Interacting with engineers, product stakeholders, analysts, planners, and teams across multiple regions is a big part of our day-to-day. We’re looking for a strong problem-solver who thrives in partnership, communicates clearly, and brings a thoughtful engineering perspective to a wide range of systems and workflows.

You’ll get…

• Competitive hourly rate, 401K company match that vests immediately upon participation, & team bonus opportunities


• Generous PTO and flexible attendance policy


• Comprehensive health and wellness benefits with options at $0 monthly, effective first day of employment


• Up to 85% discount on subscriptions to HelloFresh meal plans (HelloFresh, Green Chef, Everyplate, and Factor_)


• Access to Employee Resource Groups that are open to all employees, including those pertaining to BIPOC, women, veterans, parents, and LGBTQ+
