Senior Software Engineer ( C#) - Based in Ireland

Overview

We're building a world class modern, scalable platform at One Identity, and we're looking for engineers who want to own things end-to-end - not just write backend code and hand it off to the next functional team.

We don't hire for a single discipline. Our engineers bring serious depth in one area - typically backend development and platform/DevOps - but are genuinely capable across the full delivery lifecycle: frontend, test automation, pipelines, observability, and everything in between. Quality and customer experience are our highest priorities, which means you're not a specialist waiting for the right ticket - you're someone who follows the work wherever it needs to go, writes tests not just code, participates in functional testing, and owns customer escalations directly. We don't have a dedicated support escalation team; when a customer hits a wall, it lands with us. We take that seriously, and we'd want you to as well.

We trust our engineers to take a feature from refinement all the way to production, and we back that up with the autonomy and support to make it happen.

If you're hungry to keep growing, humble enough to know you don't have all the answers, and care deeply about the people you work with - let's talk.

Responsibilities

• Taking full ownership of features - from refinement and design through development, testing, and delivery to production
• Building and maintaining modern, scalable microservices in C# and .NET (8+) running on Azure Kubernetes Service
• Contributing across the stack - backend services, Angular UI, test automation, CI/CD pipelines - wherever the work needs you
• Writing clean, testable, well documented code and holding the bar through code reviews
• Creating and executing test cases, participating in functional testing, and managing test plans via Azure DevOps
• Working in 2 week sprints with a globally distributed team - participating in refinement, demos, and retrospectives
• Instrumenting services with OpenTelemetry and using Datadog to own the health of what you ship
• Participating in on call rotation as a primary responder for our services and the Kubernetes infrastructure that runs them - we own the full stack, not just the application layer
• Owning customer escalations directly - investigating, communicating, and resolving issues without a handoff layer between you and the customer impact
• Leveraging AI coding tools to accelerate development - we expect engineers to be fluent in AI assisted workflows, not just aware of them
• Collaborating closely with architects, product managers, and teammates across Panama, Hungary, and beyond

Qualifications

Core (you should bring depth here): - Strong C# and .NET (8+) experience building production microservices at scale - Solid grasp of CQRS, event driven architecture, and messaging systems (Azure Service Bus or similar) - Hands on with NoSQL databases - Cosmos DB, MongoDB, or similar - Experience with CI/CD tooling - Azure DevOps, GitHub Actions, or similar - Comfortable with containerization and orchestration - Docker, Kubernetes, AKS

Breadth (you don't need to be an expert, but you can hold your own): - Frontend exposure - Angular, TypeScript, HTML/CSS - Test automation - Python/Pytest, Playwright, or similar - Infrastructure as code - Bicep, Terraform, or equivalent

Practices you'll live and breathe: - Trunk based development and feature branch discipline - Git fluency and pull request based collaboration - Observability first mindset - you instrument what you ship - AI coding tools as a daily part of your workflow

Qualifications

• 4+ years of professional software engineering experience, with meaningful .NET microservices development
• Bachelor's degree in Computer Science, Software Engineering, or equivalent
• Strong English communication skills - written and verbal (our team is distributed globally)
• Self directed and comfortable working asynchronously across time zones

Nice to Have

• Familiarity with Identity and Access Management - OAuth, OIDC, SAML, SCIM, JWT
• Experience with Azure services beyond AKS (App Configuration, Key Vault, Service Bus)
• Exposure to OpenAPI spec authoring and API first design

Why Join Us

• Fully remote role
• Work on a platform used by enterprises globally to manage secure access and identity
• Small enough team that your contributions are visible; large enough org that there's real career trajectory
• Engineering culture that values ownership, continuous improvement, and shipping real things
