The role

We are looking for a hands-on Senior 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.

What you'll do

• Architectural Leadership: Design integration architectures aligned with HelloFresh's core systems (account, billing, and loyalty domains). Establish standardized patterns and templates for scalable partner onboarding.

• End-to-End Delivery: Lead the full lifecycle of new partner integrations-from initial scoping and technical solution design to implementation and go-live.

• Technical Execution: Develop and deploy robust RESTful APIs (Python/FastAPI or Node.js) and webhooks to enable bundled subscriptions and account linking.

• Partner Ownership: Act as the primary technical point of contact for external partner engineering teams. Translate complex partner requirements into concrete technical specifications.

• Strategy & Optimization: Implement logic for revenue share and loyalty attribution, ensuring integrations are reliable, secure, and compliant with global standards (GDPR/PII).

What you'll bring

• Technical Skills: * Expertise in RESTful API development (Python with FastAPI preferred, or Node.js).

  • Deep understanding of OAuth2 / OpenID Connect, webhooks, and secure token exchange.

  • Strong experience in API design, documentation (Swagger), and testing.

  • Proficiency with AWS cloud environments (Container Registry, Cloud Storage) and SQL/NoSQL databases.

• Preferred Experience: (One or more of the following)

  • Background in B2B SaaS integrations, subscription commerce, or loyalty/fintech APIs.

  • Experience managing integrations across multiple regions or complex billing systems.

• Soft Skills: 

  • Strong Ownership: Ability to independently drive technical projects from concept to production.

  • Communication: Able to translate high-level technical concepts for non-technical stakeholders and partners.
