Senior Software Development Manager

JMC is partnering with SinaLite / Willowpack to recruit a Software Development Manager to lead the development of software that connects customers, production teams and business operations.

SinaLite is a B2B wholesale print platform serving resellers across North America, while Willowpack is a growing flexible-packaging and folding-carton manufacturer. Across both businesses, software plays a central role in delivering speed, efficiency and a strong customer experience.

Reporting to the President, you will lead the development team and work closely with Operations, Finance, Sales, Marketing and Data/BI to turn business priorities into practical, reliable systems. This opportunity is ideal for a technically strong leader who enjoys solving operational challenges, managing competing priorities and ensuring the systems their team builds are successfully adopted.

Key Responsibilities

Software Delivery and Project Management

• Lead software intake, prioritization and roadmap planning across both businesses, aligning projects with business objectives.
• Manage multiple projects, including scope, milestones, dependencies, risks and stakeholder communication.
• Establish clear delivery commitments and resolve competing departmental requests to keep the development team focused.

Architecture and Business Systems

• Guide architecture decisions across legacy systems, modern applications, APIs, e-commerce platforms and reporting tools.
• Modernize existing systems incrementally while protecting business continuity, data integrity and established business logic.
• Oversee access management, technical documentation and cross-training to support reliable, secure operations.

Operational Improvement and Adoption

• Lead improvements to pricing, costing and order-management systems in partnership with Finance and Operations.
• Advance Willowpack’s customer portal and production workflows, including quoting, ordering and artwork processes.
• Deliver inventory, material planning, scheduling and traceability tools that support production efficiency and food-safety requirements.
• Partner with business teams on requirements, procedures, training and implementation, measuring adoption and addressing gaps after launch.

Team Leadership and Innovation

• Lead, coach and develop a small, experienced software development team, supporting recruitment, performance management and career growth.
• Remain technically involved through code reviews, architecture decisions and troubleshooting.
• Expand the effective use of AI-assisted development and automation, supported by strong review practices, governance and cost controls.

Qualifications and Experience

• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, Information Systems or a related field, or equivalent professional experience.
• At least seven years of software development experience, including three years leading a team delivering business-critical systems.
• Experience with ERP, MRP, inventory, scheduling, pricing or order-management systems in manufacturing or a comparable operational environment.
• Strong technical judgment across legacy applications, modern development stacks, APIs and e-commerce platforms.
• Experience managing multiple projects across departments, with clear plans, priorities and progress reporting.
• Demonstrated success leading change and helping operational teams adopt new systems.
• Practical experience using AI coding tools and agentic workflows within a development team.

Experience with Magento, NetSuite or comparable ERP integrations, SQF or traceability systems, and incremental legacy modernization would be considered assets.

Key Competencies

• Business judgment: Connects technical decisions to efficiency, revenue, margin and business priorities.
• Communication and influence: Explains trade-offs clearly and builds trust with senior leaders, technical teams and production employees.
• Prioritization: Sets realistic commitments and confidently manages competing requests.
• Change leadership: Brings stakeholders together and follows through on implementation and adoption.
• Accountability: Takes ownership of outcomes, develops people and builds systems others can maintain.
