Growth Engineer (f/m/x)

About this role

Responsibilities

• We are looking for a hands-on Growth Engineer to design, implement, and manage scalable API integrations that connect HelloFresh with external partner ecosystems including telecoms, financial providers, loyalty programs, and health/wellness platforms.
• This role combines technical execution (building and deploying APIs, data workflows, and automation) with project ownership (defining requirements, managing partners, ensuring delivery).
• You will own integrations from design to production, delivering end-to-end partner connectivity that enables subscription bundling, loyalty rewards, account linking, and nutrition data exchange, all while maintaining reliability, compliance, and a seamless customer experience.
• Integration Implementation: Build and maintain RESTful APIs and webhooks to connect HelloFresh with partner platforms for loyalty rewards and account linking.
• Execution & Support: Develop automation scripts and data workflows to handle recurring syncs and reporting for partner programs.
• Technical Documentation: Maintain high-quality API documentation and partner developer guides to ensure smooth onboarding.
• Reliability: Troubleshoot issues, manage error handling, and ensure the performance of existing integrations.
• Collaboration: Work cross-functionally with Product, Data, and Finance teams to implement business logic for revenue-sharing or benefit application.
• What You’ll Bring
• Technical Skills: * Solid experience with RESTful API development (Python/Node.js—familiarity with FastAPI is a plus).
• Good understanding of OAuth2, webhooks, and how to manage secure data exchange.
• Experience using API testing tools like Postman and documenting work via Swagger.
• Familiarity with AWS (containers) and working knowledge of SQL/NoSQL databases.
• Preferred Experience: * Interest or previous exposure to B2B SaaS, fintech, or subscription-based platforms.
• Familiarity with tools like Snowflake, Contentful, or N8N is a bonus.
• Soft Skills:
• Ownership Mindset: A proactive approach to completing tasks and ensuring code quality.
• Organizational Skills: The ability to manage multiple integration tasks and meet deadlines in a fast-paced environment.
