We are looking for a senior NewStore OMS Developer to join our team and take ownership of a critical middleware integration connecting NewStore OMS/POS with Shopify. You will be responsible for auditing an existing middleware layer, stabilizing it, and evolving it from reactive bug fixing into a scalable, feature-driven integration.
The ideal candidate brings direct, hands-on NewStore OMS integration experience and can ramp up quickly on an inherited codebase with minimal guidance.
Please Note: This is a Contract position (hourly rate). We welcome applications from across the globe, but our preferred candidates should be able to work in Eastern Standard Timezone (EST).

Document integration logic, data flows, and system changes throughout the engagement
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 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.
The following would be bonus experience to have, though highlight any additional experience or skills you may have. We like working with people with varied backgrounds and experiences.
