Opportunity for impact

Newfire Global Partners, a leader in developing disruptive healthcare technology, collaborates with Fortune 500 companies and start-ups to drive transformation.

What’s the Project? Our client is a well-established company in the luxury retail industry undergoing a significant technology transformation. Newfire is supporting the modernization of its engineering ecosystem, including business-critical enterprise systems, e-commerce operations, and integrations.

The client currently operates several applications and integration workflows within a Microsoft-based environment running on Azure. Its enterprise ecosystem includes Microsoft Dynamics GP, as well as Odoo, which supports one of the company’s key sub-brands.

• Work extensively with SQL, stored procedures, and business-critical data workflows.


• Troubleshoot integration failures, data issues, and production problems.
  Support the technical health of the client’s Microsoft Dynamics GP ecosystem and related applications.


• Learn the client’s Odoo environment and gradually contribute to its maintenance, integrations, and custom functionality.


• Improve the reliability, maintainability, and performance of existing systems.


• Collaborate with technical leads and business stakeholders to understand requirements and deliver practical solutions.


• Document integrations, system behavior, and important technical decisions.


• Adapt across platforms as the client’s enterprise technology strategy continues to evolve.


• As a Senior team member, you will be expected to actively participate in our hiring processes by serving on interview panels for future roles across the company.

Please note that employment will be contingent upon providing documentation verifying your legal work authorization in the country of residence, in accordance with applicable law.

You’re a perfect match if you have:

• 6+ years of professional backend software engineering experience.


• Strong production experience with C# and .NET.


• Strong experience with SQL and relational databases, including stored procedures and troubleshooting database-related issues.


• Experience building, maintaining, or improving REST APIs and enterprise integrations.


• Experience working with existing production systems and resolving technical debt.


• The ability to understand business-critical workflows and translate them into reliable backend solutions.


• Strong problem-solving skills and the ability to work independently.


• The ability and willingness to learn Python, Odoo, Microsoft Dynamics GP, or other enterprise platforms quickly.


• Strong English communication skills.

• Professional experience with Python.


• Experience developing or customizing Odoo modules.


• Experience with Microsoft Dynamics GP, Business Central, or another ERP platform such as SAP, Oracle, or NetSuite.


• Experience working with Azure or Microsoft-based enterprise environments.


• Experience with e-commerce or retail platforms.


• Knowledge of finance, inventory, order management, or supply‑chain processes.
