## About the Role

* Core Languages: Deep proficiency in Pascal programming, including compiling, linking, and runtime debugging on enterprise server environments.
 * Database Mastery: Strong advanced PostgreSQL skills (complex stored procedures, query optimization, transactional safety, and relational schema management).
 * UI Frameworks: Experience or strong conceptual familiarity with DEC Forms (or equivalent forms-based UI processing systems) and managing their active parallel execution sessions with back-end modules.
 * Environment Knowledge: Familiarity with OpenVMS, Linux, or Unix-like systems where such compiled applications and terminal-based forms typically reside.

Must Have Skill

Pascal

## Description

Key leadership responsibilities-

 * Incident & Problem Management: Take ultimate ownership of high-severity (P1/P2) incident escalations affecting warehouse fulfillment. Drive root-cause analysis (RCA) and ensure permanent fixes are deployed.
 * Enhancement Delivery: Oversee the end-to-end delivery of small-to-medium functional enhancements, ensuring code modifications do not introduce regression risks to core warehouse logic.
 * Vendor & Stakeholder Alignment: Partner closely with Fulfillment Unit Operations, L2 Support, Infrastructure teams, and product owners to prioritize the application backlog and bug-fix queue.

Functional & Technical responsibilities-

L3 Production Support & Deep-Dive Triage:

 * Parallel Session Debugging: Lead the debugging of complex application states where DEC Forms UI sessions run in parallel execution with underlying Pascal modules.
 * Database Performance Tuning: Investigate complex transactional bottlenecks, deadlocks, and query performance degradation within the PostgreSQL data layer.
 * Hotfix Engineering: Write, test, and safely package code-level hotfixes in Pascal to resolve critical system failures without disrupting active warehouse flows.

Continuous Enhancements & Code Modernization:

 * Feature Development: Design and implement application enhancements to optimize warehouse picking, packing, put-away, and material handling logic within MHS.
 * Refactoring & Optimization: Identify legacy code paths (Pascal/C) or inefficient DEC Forms workflows that can be refactored to improve processing speeds and system reliability.
 * System Integration: Maintain and enhance interfaces linking MHS to modern edge APIs, automation hardware (PLCs), and broader IKEA supply chain ecosystems.
