Senior Backend Engineer .Net

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

• 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
