• Driving “best in class” SaaS cloud platform practices: scalable, secure, and future-ready
• Representing IRIS externally & growing our internal tech culture
• Owning our engineering culture and helping it evolve
• Influencing technical strategy alongside our senior tech leaders

• A mentor and coach who supports career growth & technical excellence
• Strong understanding of async, memory management, performance tuning & debugging
• Comfortable with modern CI/CD, Agile delivery and large-scale systems
• An innovative mindset, excited by new tools and new ways of thinking

We’re more than just a software company — we’re a community of curious minds, supportive leaders, and bold thinkers. We care about our people, and we’re building a tech culture where engineers feel empowered to do their best work.

You’ll get:

• Autonomy to lead and experiment
