Job summary

Harmony AI is hiring an on-site Principal Product Engineer in Chattanooga, TN. You will own the internal platform architecture, define cross-plant data ontology, and accelerate deployments from weeks to days while writing code daily alongside the founders.

You will sit inside factories, build reusable platform tooling, and mentor deployment engineers to ensure scalable, high-trust implementations across customer sites.

Qualifications

• 3-5+ years building and shipping production software.
• Proficient in Python and TypeScript/React; comfortable across APIs, services, front end, and data.
• Hands-on experience with Docker/K8s, Terraform, CI/CD, and observability in production environments.
• Experience integrating with enterprise systems under security and compliance constraints.
• Track record of building internal platforms, SDKs, or developer tooling that others adopt.
• Good judgment about abstraction and avoiding over-generalization.

Responsibilities

• Define the shared data model mapping machines, ERPs, work orders, quality records, and people across plants.
• Build abstractions to map a new customer’s systems into that model in days rather than weeks.
• Work with field engineers to pressure-test the model against reality, not a whiteboard.
• Create monorepo-friendly scaffolds, code-generation templates, and CI/CD blueprints for repeatable deployments.
• Mentor deployment engineers to ensure platform usage aligns with intended design.
