Introduction

Overview

Welcome to Gallagher—a global community of people who bring bold ideas, deep expertise, and a shared commitment to doing what’s right. At Gallagher, we help clients navigate complexity with confidence by empowering businesses, communities, and individuals to thrive. You’ll find more than a job here—you’ll find a culture built on trust, driven by collaboration, and sustained by the belief that we’re better together. This is what it means to live The Gallagher Way.

We are seeking an experienced Application Developer to support Gallagher’s Global Business Resiliency (GBR) and Global Safety & Security (GSS) teams as part of our ongoing global mission and digital transformation journey. This role plays a critical part in enabling enterprise resilience, business continuity, crisis management, safety, and security outcomes by designing, building, and supporting modern business applications that enhance visibility, coordination, automation, and decision‑making across a global organization.

The ideal candidate brings strong expertise in Microsoft Power Apps and the Power Platform, complemented by solid .NET development experience and a strong foundation in SQL database design and development. You will deliver scalable, well‑architected solutions—including applications, workflows, dashboards, and collaboration tools—that support operational resilience, incident readiness, and global safety and security programs.

This is a hands‑on individual contributor role with no people management responsibilities. The successful candidate is comfortable working closely with business stakeholders, translating functional requirements into robust technical solutions, and balancing speed of delivery with sound architecture, extensibility, and long‑term maintainability. In this role, you will directly contribute to Gallagher’s ability to operate confidently in a complex, evolving global risk environment while advancing our digital capabilities in support of our people and clients.
