Are you a Principal Software Engineer with deep .NET and 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 carries full ownership of the technical delivery of a modern, Azure-based platform built using .NET. You will define engineering standards, lead architectural decisions, 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, helping to shape 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 implementation of core backend services, including API layers, scoring and probability engines, and workflow orchestration.
Own Azure runtime and infrastructure decisions, including Azure Container Apps, Azure Functions, and App Service, along with 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, running architecture and design sessions, and unblocking delivery across teams.
Do You Have?
10+ years of software engineering experience, with strong expertise in .NET/Python
Proven production experience designing and delivering systems on Microsoft Azure, including Functions, App Service, Container Apps, and CI/CD pipelines using Azure DevOps or GitHub Actions.
Strong API design and implementation experience using ASP.NET Core, RESTful services, OpenAPI/Swagger, and versioning strategies.
Solid experience with relational databases such as Azure SQL or PostgreSQL, plus Azure storage solutions (Blob Storage / ADLS) and caching technologies (e.g. Redis).
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.
