You will design and ship microservices, migrate capabilities from legacy estate, and build event-driven flows using MassTransit and Azure Service Bus, while working with Azure SQL and Redis.

Qualifications

• 6+ years commercial backend development delivering production systems.
• Strong experience with C#/.NET 8 and modern ASP.NET Core.
• Hands-on with microservices, API gateways and service-to-service auth.
• Proficient with Docker/Kubernetes and cloud-native patterns.
• Relational data modelling with Azure SQL/SQL Server; EF Core or micro-ORM.
• Experience with MassTransit, Azure Service Bus and event-driven flows.
• Solid automated testing in real dependencies and CI/CD ownership.
• Brownfield migration of legacy monoliths while live systems run.

Responsibilities

• Design, build, and ship .NET 8 microservices behind our API gateway.
• Migrate capabilities from legacy estate to the new platform in parallel.
• Develop event-driven flows with MassTransit and Azure Service Bus.
• Work across Azure SQL, Elasticsearch and Redis with proper indexing.
• Write unit and integration tests; diagnose production issues.

Job description

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 8 microservices 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.
• Building event‑driven flows with MassTransit and Azure Service Bus, with the idempotency and eventual‑consistency handling that actually survives production.
• Working across Azure 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 off development, PR back into development; release branches are cut from there.
• Documentation lives with the code and is expected to be kept current.

Requirements & Experience for the role

• 6+ years commercial 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 — unit and integration, 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.
• Redis caching 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 Framework maintenance — you will occasionally need to read and touch legacy services.
• High‑traffic public web concerns: CDN, Azure Front Door, SSR and SEO‑sensitive rendering.
• Enough Angular / TypeScript to trace a bug from the API into the frontend.
• Working with AI coding agents (Claude Code, Codex, Copilot) as part of normal delivery.
