We're looking for a Full Stack Application Engineer to join our Finance Technology team. You'll build and operate business-critical applications that connect Finance, Supply Chain, and Manufacturing, supporting hardware development and production from planning and procurement through inventory, costing, and financial reporting.

This is an end-to-end engineering role. You'll work directly with business and technical partners, turn complex operational needs into simple and reliable products, and own solutions from discovery and architecture through delivery, adoption, and production support. The ideal candidate combines strong full-stack engineering skills with an understanding of enterprise systems, data integrity, and finance or manufacturing workflows.

What you'll do:

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

• 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.

Knowledge, Skills & Abilities:

• Strong full-stack development skills using JavaScript or TypeScript and at least one modern front-end framework such as React, Angular, or Vue.
• Strong experience developing backend services and APIs using one or more languages such as Java, Python, Go, or Node.js and the ability to learn our stack quickly.
• Sound understanding of application architecture, object-oriented and domain-driven design, distributed systems, and common integration patterns.
• Ability to translate ambiguous business needs into clear product, functional, and technical requirements.
• Strong written and verbal communication skills, with the ability to work effectively across engineering and non-engineering teams.
• A practical ownership mindset: you simplify complexity, make sound tradeoffs, and follow through on reliability and user outcomes.

Minimum Qualifications:

• Bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
• 4+ years of full-stack application or software engineering experience after earning a bachelor's degree; a master's degree in a technical field plus 3+ years of post-graduate full-stack engineering experience; or a PhD in a relevant technical field.
• Professional experience building, shipping, and supporting production-grade, end-to-end web applications.
