Job Description
Senior NewStore OMS Developer responsible for integrating NewStore with Shopify. Work from anywhere while collaborating on middleware integration improvements.
Responsibilities:
- Lead audit/discovery of an existing Newstore OMS ↔ Shopify integration and middleware (architecture, data flows, failure modes).
- Take full ownership of middleware maintenance, shifting focus from reactive bug fixing to proactive feature delivery
- Develop, test, and deploy enhancements to the OMS–Shopify integration layer
- Troubleshoot and resolve integration issues between NewStore OMS and Shopify
- Collaborate with cross-functional teams (engineers, delivery managers, stakeholders) to clarify requirements, prioritize fixes, and ship improvements.
- Provide technical input on platform integration decisions and evolving requirements
- Participate in code reviews and contribute to continuous improvement of integration practices
- Document integration logic, data flows, and system changes throughout the engagement
Requirements:
- Hands-on experience integrating Newstore, ideally with a focus on Newstore OMS
- Senior-level experience owning production integrations and debugging complex systems under real-world constraints.
- Proven ability to perform technical audits and ramp quickly in partially documented or “black box” environments.
- Strong API/integration fundamentals (REST, webhooks/event-driven patterns, async processing, data consistency, reconciliation workflows).
- Strong software engineering fundamentals (system design, data modeling, testing strategies).
- Strong written and verbal communication skills for async, cross-functional collaboration
- Ability to work with meaningful overlap in Eastern Time (ET/EST) hours.
Benefits:
- Work From Anywhere: Choose your workspace — all you need is strong wifi and a passion for building!
- Work / Life Balance: We believe in our team’s ability to have it all; a great career, and time to unplug and live…you know...life.
- Employee Care: We provide full benefits (healthcare, dental, vision) for our employees (401k for our US employees)
- Unlimited PTO: Everyone needs a break. Take at least 15 days off a year, and more if you need—just be cool about it and keep the team in mind.
- Regular Team Retreat: Join us for a week of team bonding at amazing destinations. Recent trips include the Dominican Republic, Cancun, and Hawaii — plus ones welcome.
