- Design, build, test, deploy, and operate secure, scalable web applications and services used by Finance, Manufacturing, Supply Chain, and Operations teams.

- Own features across the full stack, including user experience, data models, APIs, business logic, integrations, automated testing, and observability.

- Develop reliable integrations among ERP, MRP, MES, PLM, warehouse, procurement, finance, and analytics platforms using APIs, events, and batch processing at Scale.

- Partner with product managers and business stakeholders to understand processes, challenge assumptions, define requirements, and deliver measurable outcomes.

- Improve system performance and resilience through monitoring, alerting, service-level objectives, capacity planning, and effective incident response.

- Raise engineering quality through design reviews, code reviews, automated tests, CI/CD, documentation, and pragmatic technical standards.

- Share knowledge, mentor teammates, and help create an inclusive, high-ownership engineering culture.
