As a Senior Software Engineer for John Deere Harvester  Works located in Des Moines, IA , you will:   Own the end‑to‑end technical excellence of the Operations product and its enterprise integrations. You will also:

Design, develop, and deliver complex applications and services that integrate with enterprise platforms (data, identity, observability, CI/CD), ensuring secure, reliable, and scalable solutions for factory operations. Lead solution architecture and code quality: define patterns, interfaces, and performance budgets; conduct and set the bar for code/design reviews; drive clean, maintainable, well‑tested code across the stack. Set and evolve the technical vision with the Software Engineering Manager—translate product outcomes into technical strategy, roadmaps, and architecture runway; de‑risk delivery through spikes and proofs‑of‑concept. Coach and mentor teammates on system design, debugging techniques, testing strategy, and our technical stack (e.g., React/TypeScript, APIs, data stores, pipelines); grow engineering capability through pairing, knowledge shares, and actionable feedback. Own reliability and test engineering practices: champion automated tests (unit, integration, end‑to‑end), performance monitoring, and resilience patterns; lead root‑cause analysis for complex incidents and drive preventative measures. Drive DevOps excellence: maintain CI/CD pipelines, deployment automation, and environment health; ensure observability (logs, metrics, traces) and operational readiness . Guard information security in design and implementation (least privilege, secure coding, dependency hygiene) and partner with platform/security teams to remediate findings quickly. Collaborate cross‑functionally with product management, UX, factory stakeholders, and enterprise platform teams to align technical choices with business outcomes; communicate trade‑offs and data‑driven recommendations clearly. Steward documentation: author and maintain architecture decision records, API contracts, production support guides, and onboarding materials to ensure product continuity and scale. Continuously improve the product and process: identify bottlenecks, propose experiments, and measure impact (quality, cycle time, MTTR, cost); model curiosity and technical leadership across the broader community.
