This role is ideal for a senior, hands-on engineer with deep expertise in C# and .NET, a strong foundation in distributed systems and backend architecture, and practical experience shipping frontend and mobile features. Experience building software in healthcare or other regulated environments is highly preferred.

Note: This position is remote but requires travel across the Middle East to collaborate with the FluidAI team and clients.

Job Responsibilities

Backend & Systems

• Design, build, and own scalable, secure, and highly available backend services and APIs using C#, .NET, and ASP.NET Core.
• Architect systems for ingesting, processing, and storing high-frequency sensor and device data reliably, including real-time and near-real-time pipelines.
• Lead technical design for new services and major features, making sound decisions around service boundaries, data models, messaging, and scalability.
• Design and optimize relational and time-series data stores (e.g., SQL Server, PostgreSQL), including schema design, query performance, and data integrity.
• Design, build, and maintain solutions on NoSQL databases (e.g., MongoDB, Azure Cosmos DB, Redis), including document modeling, indexing strategies, and choosing the right data store for each workload.
• Build and maintain event-driven and asynchronous workflows using message brokers and queues (e.g., Azure Service Bus, RabbitMQ, Kafka).
• Develop integrations with hospital and third-party systems, including EHR/EMR platforms, using healthcare interoperability standards such as HL7 and FHIR.
• Own system reliability and operability: logging, monitoring, alerting, tracing, and incident response for production services deployed in clinical settings.
• Build and maintain cloud infrastructure, containerized deployments, and CI/CD pipelines that support safe, repeatable releases.

Full-Stack & Integration

• Work across our full-stack codebases, delivering features end-to-end from database and API through to web and mobile user interfaces.
• Build and maintain frontend features in React and Next.js, and mobile features in React Native, following established patterns and contributing to shared components where needed.
• Connect backend services to frontend and mobile clients: design API contracts, implement authentication and authorization flows, manage data fetching and state, and handle error and offline scenarios.
• Implement real-time data delivery to web and mobile clients (e.g., SignalR, WebSockets, push notifications) so that clinicians see device and patient data as it happens.
• Partner with frontend, mobile, and design teammates to shape APIs around how the product is used, and keep backend and client code consistent and well-tested.
• Debug and resolve issues across the full stack, tracing problems from the UI through APIs, services, and data stores.

Engineering Practice & Collaboration

• Apply security, privacy, and compliance best practices throughout the software lifecycle, especially when handling sensitive patient and clinical data.
• Write and maintain technical documentation, including architecture decisions, API specifications, and design artifacts that support regulatory and quality requirements.
• Mentor engineers, drive code review standards, and raise the engineering bar across the team.
• Participate in sprint planning and Agile ceremonies, contributing to roadmap planning and prioritization from a systems and architecture perspective.
• Collaborate closely with hardware, firmware, ML, data, and clinical teams to deliver features end-to-end across the full technology stack.

Qualifications

• 7+ years of professional software engineering experience, with significant time spent building production backend systems.
• Expert-level proficiency in C# and .NET (.NET 6+ / ASP.NET Core), including Web API development, dependency injection, async programming, and Entity Framework Core or similar ORMs.
• Strong background in distributed systems and backend architecture, including microservices or modular monoliths, REST and/or gRPC APIs, caching, and event-driven design.
• Advanced SQL skills and strong data modeling experience with relational databases such as SQL Server or PostgreSQL, plus hands-on experience with NoSQL databases such as MongoDB.
• Hands-on experience with a major cloud platform (Azure preferred; AWS or GCP considered), including managed services, networking, and identity.
• Experience with Docker, Kubernetes or similar container orchestration, infrastructure as code, and CI/CD tooling.
• Solid understanding of application security, including authentication and authorization (OAuth 2.0, OpenID Connect), encryption, and secure handling of sensitive data.
• Experience with observability and production operations: structured logging, metrics, distributed tracing, and on-call/incident response.
• Proven experience working in a full-stack environment, with hands-on production work in TypeScript, React, and Next.js.
• Experience building or contributing to mobile applications with React Native.
• Strong understanding of how frontend and backend fit together, including API design for client consumption, state management, auth flows, and real-time communication.
• Experience working with IoT, sensor, time-series, or high-volume streaming data is a strong plus.
• Prior experience in healthcare, medical devices, or digital health is highly preferred, including familiarity with HL7/FHIR, and with privacy and regulatory frameworks such as HIPAA, PHIPA, or Saudi PDPL.
• Familiarity with medical device software standards (e.g., IEC 62304, ISO 13485) or experience working in other regulated environments is a plus.
• Fluent in English; Arabic is a strong plus. Ability to communicate technical decisions clearly to diverse stakeholders.
• Comfortable working in cross-functional, fast-paced, and collaborative environments.
• Strong problem-solving mindset with a bias toward impact, ownership, and continuous improvement.
