Job description

Role & responsibilities

• Serve as the recognized technical authority for the Label Traxx ERP platform and its integration ecosystem, shaping engineering standards, architecture, and long-term technical direction.
• Own the AWS architecture underpinning all Label Traxx integrations Cloud API, Batched, Siteline, Data Warehouse, and Supplier integrations ensuring each is scalable, secure, and operationally mature on a shared cloud foundation.
• Drive the strategic roadmap for modernizing the legacy 4D-based Label Traxx platform, extending capability through AWS-native services across all integration points, and resolving highly complex cross-cutting technical challenges through expert judgment.
• Define and evolve PostgreSQL data architecture and modeling standards shared across Label Traxxs integrations, ensuring data integrity, performance, and consistency at scale.
• Guide architecture and technical direction for React-based frontends used by Label Traxx and its integration partners, ensuring consistency with backend and API design.
• Partner with the Architecture Review Board to define and evolve organization-wide standards for secure engineering, scalability, CI/CD, observability, and AI-assisted development practices.
• Improve engineering productivity, reliability, and delivery outcomes across the Label Traxx platform and its integration teams.
• Coach senior and staff-level engineers across Label Traxx and integration teams, influencing technical decisions and building organizational capability.
• Communicate technical direction, architecture decisions, and trade-offs to executive and cross-functional stakeholders (Product, Engineering, QA, Security, Operations).

Preferred candidate profile

• Bachelors degree in Computer Science, Engineering, or related field (Masters a plus).
• 12+ years of software engineering experience, including significant time in technical leadership, architecture, or principal engineering roles.
• Deep, hands-on AWS expertise across multiple production services (e.g., ECS/Fargate, API Gateway, DynamoDB, S3, Secrets Manager, CloudFormation/SAM) able to define cloud architecture standards applied consistently across several integrations, not a single service.
• Proven experience architecting complex, integration-heavy enterprise platforms designing and scaling multiple system-to-system integrations (APIs, batch processes, data warehousing, or supplier/EDI-style integrations).
• Strong PostgreSQL expertise, including data modeling, performance tuning, and schema design for high-transaction enterprise systems.
• Experience with React and modern frontend architecture; able to guide frontend/backend integration decisions.
• Strong background in C#/.NET (ASP.NET Core) and enterprise API design; proven experience modernizing legacy or monolithic systems into service-oriented or cloud-native architectures.
• Proven track record defining engineering standards, secure engineering practices, and CI/CD strategy across multiple teams.
• Demonstrated ability to mentor senior engineers and influence technical direction beyond a single team.
• Excellent communication skills; able to align technical and executive stakeholders on architecture, trade-offs, and risk.
• Experience guiding organization-wide adoption of AI-assisted development tools and practices is a plus.
