Principal Software Engineer – Greenfield AI Platform!

Principal Software Engineer – Greenfield AI Platform! Ready to shape the future of software engineering with AI at the core? I’m partnering with an innovative global SaaS organisation in Dublin, looking for a Principal Software Engineer to help drive the next generation of cloud-based products. This is a chance to go beyond traditional software development and help redefine how engineering teams build software using AI. You’ll combine hands-on coding, technical leadership and architectural influence, designing scalable cloud solutions while exploring AI agents, LLM-powered workflows and intelligent automation across the software development lifecycle. Working alongside talented engineers and product leaders, you’ll have a genuine voice in technical strategy, influence engineering standards and mentor the next generation of developers. From shaping system architecture to bringing AI-driven capabilities into production, you’ll play a key role in turning ambitious ideas into real-world products. What makes this opportunity exciting? - Greenfield development and the opportunity to shape modern SaaS products. - AI at the heart of engineering, including agentic systems and LLM-powered solutions. - Real technical ownership across architecture, system design and engineering standards. What we’re looking for: - 7+ years of software engineering experience, ideally in SaaS or product-led environments. - Strong hands-on experience with TypeScript, JavaScript, Node.js, Python and modern frameworks. - Proven experience designing scalable cloud-native systems and microservices. - Practical experience building AI agents, integrating LLMs or applying AI-assisted engineering workflows.
