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.

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 SQL Server — schema design, migrations, query performance •        JWT-based authentication / authorization, ideally across multiple services •        Hands-on AWS — App Runner (or ECS / containers), RDS, S3, SQS, Secrets Manager •        Experience with microservices and a layered / Clean Architecture approach •        Comfortable writing automated tests and working with CI/CD pipelines •        Solid understanding of application security fundamentals Nice to have •        Payment gateway integrations (Stripe / PayPal) •        Real-time / video SDKs (Agora or similar) •        Healthcare or other regulated / compliance-driven domains •        Docker and Linux container deployments Tech stack Area Technology Language / runtime C#, .NET 10, ASP.NET Core 10 (Minimal APIs) Data EF Core 10, SQL Server (AWS RDS), ASP.NET Core Identity Auth JWT Bearer, Google OAuth Libraries FluentValidation, AutoMapper, Refit, Serilog, Swashbuckle / Swagger Integrations Stripe, PayPal, Agora (video), Firebase (push) Cloud AWS — App Runner, RDS, S3, SQS, CloudFront, Secrets Manager Testing MSTest, Moq, EF Core InMemo
