  • Implement secure payment systems and escrow functionalities.

  • Develop and maintain API integrations with third-party services (payments, compliance verification).

  • Optimise platform performance, scalability, and user experience.

  • Collaborate with the CTO on technical architecture, design, and strategy.

What You Bring

  • 3+ years of full-stack development experience.

  • Strong PHP proficiency with professional WordPress/WooCommerce development experience.

  • Frontend skills using JavaScript, React, or other modern frameworks.

  • Database design and optimisation experience (MySQL/PostgreSQL).

  • Experience designing and integrating RESTful APIs.

  • Strong understanding of secure coding practices and GDPR compliance.

  • Ability to work independently, make pragmatic technical decisions, and take ownership of tasks.

Ideal Background

  • Experience building marketplace or e-commerce platforms.

  • Payment gateway integration experience (Stripe, PayPal).

  • Experience developing B2B or enterprise-level software.

  • Familiarity with YITH or similar WooCommerce plugins.

  • Exposure to healthcare or other regulated industries.

  • DevOps skills (AWS, Docker, CI/CD pipelines).

Why Join Zenrox

  • Foundational engineering role with meaningful ownership and equity.

  • Opportunity to build essential healthcare procurement infrastructure.

  • Freedom to design and implement solutions end-to-end.

  • Direct collaboration with the founding leadership team.
