Salary: Competitive salary

The Company

MyHome.ie is Ireland’s most trusted digital property marketplace, connecting buyers, sellers, renters, and agents nationwide. Founded in 2001 and part of the Irish Times Group.

The Role

We are rebuilding the MyHome.ie backend as a.NET 8 microservices platform on Azure Kubernetes, and migrating a large legacy .NET Framework / ServiceStack estate onto it service by service — with no downtime on a live, revenue-generating platform. Several new services are already in production; more are queued to follow.

The successful candidate will join a small team working exclusively on the new platform, own services end-to-end, and be trusted to ship without close supervision. This is a hands‑on delivery role: we need code in production, not a discovery phase.

Key Responsibilities

• Designing, building and shipping.NET 8microservices behind our API gateway — from data model to deployed pods.
• Migrating capabilities off the legacy estate onto the new platform (strangler-fig style), including the integration layer that keeps old and new consistent while both run in parallel.
• Buildingevent-drivenflows with MassTransit and Azure Service Bus, with the idempotency and eventual-consistency handling that actually survives production.
• Working acrossAzure SQL, Elasticsearch and Redis— schema design, query performance, index and cache strategy.
• Writing the unit and integration tests that prove your change works, and diagnosing issues in production via App Insights.
• Owning your slice of the delivery pipeline: Dockerfiles, Kubernetes manifests, Azure Pipelines.
• Reviewing peers' code, and reviewing and steering output from our AI-assisted development pipeline.

How we work

• Small team, short feedback loops, sprint-based delivery tracked in Jira.
• Every change goes through pull-request review — by humans and by our AI reviewer, which runs automatically on open PRs. Some tickets arrive with an AI-generated first draft; reviewing and correcting that is part of the job, and we treat it as a skill.
• Feature branches offdevelopment, PR back intodevelopment; release branches are cut from there.
• Documentation lives with the code and is expected to be kept current.

Requirements & Experience for the role

• 6+ yearscommercial backend development, at least 2 at senior level, delivering production systems.
• C# and .NET 8(or 6/7 with recent 8 work) — modern ASP.NET Core, DI,async/await, structured concurrency.
• Production microservices at real scale— API gateway patterns, service-to-service auth, resilience/retry (Polly or equivalent), timeouts, idempotent handlers.
• Docker and Kubernetes day-to-day— reading and writing manifests, debugging a failing pod without help.
• Relational data— solid SQL Server / Azure SQL modelling and query tuning; EF Core and/or a micro-ORM.
• Asynchronous messaging— MassTransit, Azure Service Bus, or a close equivalent.
• Automated testing you wrote yourself— unitandintegration, against real dependencies where it matters.
• Brownfield migration experience— extracting capabilities from a legacy monolith or older service estate while both generations run live.
• CI/CD ownership (Azure DevOps Pipelines ideally), disciplined Git branching, Jira.
• Genuine autonomy: able to pick up a ticket with gaps in it, ask the right three questions, and deliver.
• Rediscaching and invalidation at scale.
• Microsoft Entra ID— OIDC/OAuth2, machine-to-machine client credentials, consumer identity (CIAM/B2C-style).
• Ocelot, YARP, or another .NET gateway.
• ServiceStack or .NET Frameworkmaintenance — you will occasionally need to read and touch legacy services.
• High-traffic public web concerns: CDN, Azure Front Door, SSR and SEO-sensitive rendering.
• EnoughAngular / TypeScriptto trace a bug from the API into the frontend.
• Working withAI coding agents(Claude Code, Codex, Copilot) as part of normal delivery.
