Principal Software Engineer

Role Description: Amtech is seeking a Principal Software Engineer / Architect to serve as the technical authority for our Label Traxx ERP platform and its ecosystem of integrations. This role owns the architecture and long-term technical direction of Label Traxx and the AWS-hosted systems that connect to it — including Cloud API, Batched, Siteline, Data Warehouse, and Supplier integrations — ensuring the platform scales reliably as Amtech’s customer base and integration footprint grow
This is a hands-on architecture role: you will define and evolve the AWS architecture, PostgreSQL data layers, and React-based frontends underpinning Label Traxx’s integration ecosystem, resolve highly complex cross-cutting technical challenges spanning multiple systems, and drive the multi-year modernization strategy that extends Label Traxx’s legacy 4D- based application through modern, AWS-native services. Deep, hands-on AWS expertise is required, since AWS underpins every integration in this ecosystem.
You will partner with Amtech’s Architecture Review Board and engineering leadership to set
organization-wide standards for secure engineering, scalable architecture, CI/CD, automation,
and AI-assisted development — and you will coach senior engineers across the Label Traxx
and integrations teams to build lasting technical capability.
We value engineers who embrace modern development practices, including collaborative Git
workflows, CI/CD, Agile delivery, and responsible use of AI-assisted development tools to
improve productivity and code quality.
Qualifications
Bachelor’s degree in Computer Science, Engineering, or related field (Master’s a plus).
12-15 years of software engineering experience, including significant time in technical leadership, architecture, or principal engineering roles.
Hands-on experience in designing and implementing agentic workflows and AI-driven solutions.
Strong practical experience with MCP (Model Context Protocol), RAG (Retrieval-Augmented Generation), LLMs, and related GenAI technologies.
Experience building, integrating, and deploying LLM-powered applications and AI agents in real-world environments.
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.
