Are you a Principal Software Engineer with strong Python and Microsoft Azure experience, looking to lead the design and delivery of a brand-new greenfield platform?

A fast-growing, technology-driven company is seeking a Principal Engineer to join its expanding engineering team in Dublin. This role sits at the core of the business and offers full ownership of the technical delivery of a modern, cloud-native platform built on Azure and Python. You will define architecture, set engineering standards, and ensure the platform is scalable, secure, and production-ready from day one.

Operating in a highly engineering-led environment, you will collaborate closely with senior stakeholders and one of the company’s founders, directly shaping both the long-term technical vision and the engineering culture. This is a true greenfield opportunity where clean architecture, cloud-native patterns, and modern engineering practices are expected and encouraged.

Your Mission

• Lead the architecture and development of core backend services, including API layers, business logic engines, and workflow orchestration.
• Own Azure infrastructure and runtime decisions, including Azure Functions, Container Apps, and App Service, as well as multi-environment deployment strategies.
• Define API contracts using an OpenAPI-first approach and establish code quality standards, review processes, and engineering best practices.
• Act as a senior technical leader by mentoring engineers, leading architecture and design sessions, and unblocking complex technical challenges across teams.

Do You Have?

• 10+ years of software engineering experience, with deep expertise in Python.
• Proven production experience designing and delivering systems on Microsoft Azure, including Functions, Container Apps, App Service, and CI/CD pipelines (Azure DevOps or GitHub Actions).
• Strong API design and implementation experience using RESTful services, OpenAPI/Swagger, and versioning strategies.

Why This Is a Great Opportunity

• Full technical ownership of a modern, greenfield Azure platform with real business impact.
• A high-visibility Principal role with direct access to senior leadership and key decision-makers.
• The opportunity to influence architecture, engineering standards, and team culture from the ground up.

This role is ideal for a Principal Software Engineer who wants to own complex, high-impact systems and play a defining role in shaping the future of a growing technology organisation.
