The Roles

We’re kicking off 2026 with exciting expansion in our Devices Team, forming a new squad and hiring across Junior, Intermediate, and Senior Software Engineer levels.

In these roles, you’ll contribute to the design, development, testing, and maintenance of Gallagher’s next-generation security solutions. You’ll work at the intersection of hardware and software, collaborating closely with hardware engineers, cross-functional squads, and project teams to turn concepts into robust, manufacturable software solutions with real global impact.

You’ll bring a growth mindset, strong engineering fundamentals, and pride in delivering quality outcomes. Comfortable working in fast-moving, agile environments, you value learning, teamwork, and building software that’s reliable, scalable, and fit for production. Across all levels, you’ll write high-quality code, follow modern development practices, and contribute to Learning First Product Development (LFPD) to strengthen engineering standards and continuous improvement across the squad.
