What You’ll Do- Build and maintain platform services and APIs that support merchant integrations and external partners.
- Design and implement integrations with ecommerce platforms (e.g., Shopify) and other commerce systems.
- Write clean, readable, and extensible code in Node.js and TypeScript for backend services and APIs.
- Experience working integrating external APIs at scale.
- Contribute to select frontend or admin interfaces (React) that support platform functionality and operations.
- Participate in technical design discussions: scoping solutions, identifying tradeoffs, and breaking work into deliverable units.
- Collaborate closely with other engineers through code reviews, pairing, and group problem-solving.
- Improve system reliability, observability, and performance across platform services.
- Help evolve Wizard’s integration architecture as we scale to more partners and higher traffic.
- Write and maintain technical documentation for services, APIs, and development practices.
- Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.
- 4-6+ years of professional software engineering experience.
- Experience building or maintaining Shopify apps or ecommerce platform integrations.
- Strong experience building server side applications in Node.js / TypeScript.
- Experience writing and consuming RESTful and/or GraphQL APIs.
- Comfortable working with SQL databases (PostgreSQL, MySQL) and NoSQL (MongoDB) datastores.
- Solid understanding of web application architecture, system design, and service boundaries.
- Comfortable collaborating in a team environment and explaining technical decisions clearly.
- Experience integrating with third-party platforms or external APIs.
- Proficiency with Git and modern development workflows (PRs, CI, code review.)
- Proficiency with modern frontend frameworks (React, Vue, etc) at least at an integration level.
- Experience working in an environment with sensitive user data or compliance regulations (PCI, SOCS2, HIPPA, etc.)
- Owning meaningful components of the platform end to end, and platform services and integrations that you own are stable and scalable under growing traffic
- Independently designing and implementing reliable and scalable integrations with external partners
- Merchant and partner integrations are easier to build, extend and maintain
- You raise the technical bar through thoughtful design, strong code reviews and clear documentation and your code meets high standards for readability, testability and maintainability
- You act as a trusted platform engineer and balance speed, quality and long term system health
The expected base salary range for this role will vary based on skills, experience, role level, and geographic location. Final compensation will be determined by considering these factors alongside overall role scope and responsibilities.
