We are seeking a seasoned Backend Engineering Expert to drive the growth and enhancement of our mission-critical healthcare and procurement platforms. This high-profile role requires you to design, develop, and operate secure, event-driven microservices and APIs that ensure superior performance, reliability, and seamless integration across our systems.

This is a fully remote position where you'll collaborate with talented engineers, product owners, and business stakeholders to deliver solutions that genuinely make an impact.

Key Responsibilities :

  • Create robust ASP.NET Core Web APIs (REST / GraphQL) and background workers that meet industry standards.
  • Build scalable event-driven services using Kafka : producers / consumers, idempotent processing, retry / DLQ strategies.
  • Apply Domain-Driven Design & clean architecture principles to ensure code modularity, maintainability, and testability.
  • Develop and implement data workflows : EF Core, SQL Server, transactions, migrations, and performance tuning.
  • Implement robust integration patterns : transactional outbox / inbox, correlation IDs, distributed tracing.
  • Integrate with workflow automation tools for enhanced productivity.
  • Add observability features using Serilog, metrics, and distributed tracing.
  • Maintain security and reliability best practices (rate limiting, input validation, OWASP ASVS).
  • Participate in automated testing (unit / integration / contract, load / performance) and code reviews.
  • Collaborate effectively with cross-functional teams.

Requirements :

  • Minimum 5+ years backend engineering experience, with at least 2+ years in .NET Core / ASP.NET Core in production.
  • Thorough knowledge of microservices patterns (saga, outbox / inbox, circuit breaker, retries, idempotency).
  • Advanced Kafka expertise : topics, partitions, consumer groups, offset management.
  • Deep understanding of SQL fundamentals : query plans, indexing, transactions, isolation levels, EF Core.
  • Experience with on-prem Kubernetes : containers, networking, scaling, health / readiness probes.
  • Proven observability skills : logs, metrics, tracing, diagnostics, performance profiling.
  • Strong security mindset : API hardening, secrets management, least privilege.
  • Familiarity with CI / CD pipelines (Azure DevOps Server, Git) and code quality tools (SonarQube).
  • Excellent communication and documentation skills.

    • Prior experience with Redis, Nginx, GraphQL, SignalR, event sourcing, CQRS, or performance engineering at scale is highly desirable.
