Responsibilities

• Production Support & Operational Reliability. Troubleshoot and resolve complex L3+ production issues across supported platforms, leveraging AI agents to correlate logs, summarize incident timelines, and generate knowledge-transfer materials.
• Stakeholder Partnership & Technical Communication. Collaborate with business analysts, architects, product partners, and engineers to translate needs into practical technical solutions, using AI agents to draft design notes, compare options, and refine decision materials.
• Technical Leadership & Mentorship. Share reusable engineering patterns, prompt templates, and workflow improvements; mentor teammates on prompt engineering, responsible AI review, and agentic SDLC practices.

Requirements

• Enterprise Platform Expertise. 5–7 years of software/platform engineering experience with advanced, hands-on knowledge of ServiceNow and Atlassian products (Jira, Confluence); demonstrated ability to configure, integrate, upgrade, and troubleshoot across diverse environments.
• AI-First Engineering Fluency. Practical experience applying AI agents, prompt engineering, and context management to engineering workflows — including code generation, test creation, debugging, incident analysis, and stakeholder communication — with proven ability to critically validate generated outputs before use.
• Secure, Production-Grade Development. Proficiency in JavaScript, GlideScript, Python, or comparable scripting languages; strong command of secure coding practices, least-privilege principles, REST/SOAP API design, and AI-specific risk awareness including prompt injection and data leakage.
