Application Developer

Summary

The Senior Software Engineer owns KRS (K Retail Solutions), our live retail platform that runs in-store POS, the store Back Office, KRS Admin, and the KRS Store App across multiple store tenants.

This role combines deep, hands-on knowledge of KRS with an AI-driven way of working: the engineer directs AI coding tools in natural language ("vibe coding") to deliver features quickly, while personally owning the system architecture and design decisions that keep KRS reliable.

Just as importantly, the engineer reviews, tests, and corrects AI-generated code and designs, as well as vendor deliverables, before anything reaches our stores. As a senior member of the team, the role makes key technical decisions, is accountable for release quality and production stability, and mentors and supports other developers.

Essential Duties & Responsibilities AI-Driven Development

• Build and enhance KRS features by directing AI coding assistants in natural language. Break work into clear, verifiable tasks, guide the AI through implementation and testing, and deliver working features across POS, checkout and payments, refund/exchange, Back Office, KRS Admin, and the KRS Store App. Architecture & Technical Design
• Own the KRS architecture on the Odoo framework (KRS Admin on Odoo 18) in a multi-tenant environment. Design integrations with payment terminals and processors (CodePay, Elavon/Converge), the Snowflake data platform, and enterprise systems. Write design documents and decision records, and evaluate vendor designs and effort estimates. Review & Correction of AI-Generated and Vendor Work
• Review every AI-generated change, design, and estimate before it is merged or accepted. Check it against the business specification and the actual code, find defects, missing work items, and hidden risks (for example, a module dependency that could take POS offline), and correct them. Review vendor merge requests and provide clear feedback. Production Quality, Deployment & Incident Response
• Own release quality for KRS: feature branches and merge requests, Dev -> Staging -> Production deployments through Jenkins, module upgrades across store tenants, and post-deployment verification. Lead root-cause analysis and hotfixes for production issues, especially card-payment, refund, and end-of-day settlement issues, and maintain automated tests. KRS Domain Ownership & Stakeholder Collaboration
• Serve as the go-to expert on KRS and on store operations. Work with Sales Operations, store teams, the project manager, and vendors to turn specifications and Figma designs into clear, deliverable scope; take part in project meetings and track schedule risks. Senior Technical Leadership & Developer Support
• Make technical judgment calls, set coding, review, and AI-usage standards, and mentor and support other KRS developers, including helping them adopt AI-driven development safely. Keep technical documentation current.
