SeniorBackendEngineer

### About the role Soficopharm's platform is a healthcare product connecting patients and doctors — appointment booking, video consultations, prescriptions, and payments — built as a set of .NET microservices with a React doctor portal and a Flutter patient app. We're hiring a Senior Backend Engineer to own and mature our .NET services. You'll be the technical owner of three core backend microservices (Doctor Auth, Patient Auth, Patient Booking) and future services , driving a hardening-and-refactoring effort: closing security findings, raising test coverage, tightening CI/CD, and keeping the services healthy as the platform scales. This is a hands-on ownership role with real architectural influence — not a ticket-taking position. ### What you'll do • Own the design, development, and maintenance of our .NET microservices (authentication, booking, payments, consultations..etc) • Lead a refactoring effort on existing services — reducing oversized classes, improving separation of concerns within a Clean Architecture layout, and paying down technical debt safely • Harden security: per-service JWT signing keys, secrets management via AWS Secrets Manager / SSM, auth flow correctness, and remediation of findings from a recent security audit • Design and evolve data models with Entity Framework Core and SQL Server, including migrations • Build and maintain integrations: payment gateways (Stripe, PayPal), real-time video , push notifications, and inter-service APIs • Grow automated test coverage (unit and integration) and strengthen the GitHub Actions CI/CD pipelines • Operate services on AWS (App Runner, RDS, S3, SQS) — deployments, observability, and incident response • Collaborate with the frontend (React) and mobile (Flutter) teams on API contracts **Requirements** **What we're looking for** **Required** • 4+ years of backend engineering, with strong C# and .NET (.NET 8 / 9 / 10) • Deep ASP.NET Core experience, including Minimal APIs • Strong Entity Framework Core and SQ
