Job description

Requirement - Senior Full-Stack Engineer

Location- Irvine, CA

Contract W2

Job Description:
Overview

We are seeking a Senior Full-Stack Engineer to support the development of internal Incident Management Tools used by Central Technical Operations Services (C-TOS). This role is focused on building high-impact features that reduce operational toil, improve incident response efficiency, and increase team capacity.

This is a hands-on, backend-leaning full-stack role requiring end-to-end ownership across design, development, testing, and delivery in a fast-paced, complex environment.

Key Responsibilities

  • Design, develop, test, and deliver production-ready features end-to-end (no separate QA handoff)
  • Build and enhance internal tooling platforms supporting incident management workflows
  • Develop scalable services and APIs using TypeScript/Node.js-based frameworks
  • Contribute across the full stack, including Vue.js (or React) frontend components
  • Implement cloud-native solutions leveraging AWS services (Lambda, DynamoDB, SQS, etc.)
  • Deploy and manage infrastructure using AWS CDK or similar IaC frameworks
  • Collaborate with cross-functional teams to navigate dependency-heavy systems and approvals
  • Optimize systems for performance, reliability, and operational efficiency

Core Deliverables

  • Build automation-driven features that reduce manual effort (toil) and improve operational workflows
  • Deliver enhancements across Incident Management Tooling, including:
    • Automated paging escalation workflows
    • UI consolidation to reduce context switching
    • Service directory improvements for faster resolution
    • Workstream timeline enhancements
    • On-call rotation visibility and tracking
    • Auto-correlation of users to incidents/pages
    • Intelligent autofill of team/group data
    • Automated MIN (Major Incident Notification) workflows
    • CloudWatch dashboard/chart integration
    • Full audit logging of user/system actions
    • COE (Correction of Error) workflow improvements
    • Integration of auto-summarized incident call data

Required Qualifications

  • Strong full-stack engineering experience with a backend-first focus
  • Hands-on experience with:
    • TypeScript, Node.js
    • Vue.js (preferred) or React
  • Proven ability to build:
    • APIs, backend services, and distributed systems
  • Experience working in cloud environments (AWS strongly preferred):
    • Lambda, DynamoDB, SQS, CloudWatch, etc.
  • Familiarity with Infrastructure as Code (CDK preferred)
  • Demonstrated ability to:
    • Work in agile, fast-moving environments with shifting priorities
    • Own features from concept through production
    • Navigate complex systems with cross-team dependencies

Preferred Qualifications

  • Prior experience in large-scale engineering environments (Amazon or similar is a plus, not required)
  • Experience building internal tools, platform systems, or operational tooling
  • Exposure to:
    • Incident management systems
    • Automation and workflow optimization
    • Observability, logging, and monitoring systems

Ideal Candidate Profile

  • Backend-leaning full-stack builder who can contribute immediately
  • Experience delivering high-impact tooling that improves efficiency and incident response
  • Comfortable in ambiguous, high-ownership environments
  • Able to operate with minimal ramp-up and oversight

What This Role Is NOT

  • Not a frontend-heavy/UI-only role
  • Not a split Dev/QA structure
  • Not suited for candidates requiring extended onboarding

Why This Role

  • Direct impact on critical incident management systems
  • Opportunity to build tooling that reduces operational burden at scale
  • High ownership and visibility working with C-TOS and incident command teams

Quick Disqualifiers

  • Limited or no TypeScript/Node.js backend experience
  • Primarily frontend/UI-focused backgrounds
  • Unable to meet Irvine onsite expectations (or hybrid requirement)
  • Requires significant ramp-up/support
