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 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)
