Fractional Senior Back-End Engineer

Position Overview

We’re looking for a Senior Back-End Engineer for a 6-month contract to help build the core cloud services, APIs, microservices, and data workflows that power Youtopia’s precision nourishment automation platform.

You will build on top of the latest Azure ecosystem, using .NET 10, distributed event systems, secure data pipelines, and healthcare‑grade architecture patterns. You’ll partner closely with engineering leadership to lay the foundation for a system that must scale safely, securely, and intelligently to eventually support tens of millions of users.

This is not a maintenance role.

This is greenfield product engineering at a mission‑driven startup where the work you ship will go directly into production and directly impact lives.

What You Will Own Back‑End Architecture & Development

• Build modern, cloud‑native backend services using .NET 10 and C#
• Design and develop robust APIs, microservices, and domain‑driven components
• Implement event‑driven and distributed systems for mission‑critical workflows
• Optimize services for performance, reliability, scalability, and fault tolerance

Cloud Engineering (Azure)

• Implement services using Azure Functions, API Management, Service Bus/Event Grid, Cosmos DB, SQL, Key Vault, and distributed caching
• Contribute to designing secure, multi‑tenant architectures
• Improve end‑to‑end monitoring, telemetry, and observability

Security & Healthcare‑Grade Development

• Implement secure‑by‑default patterns suitable for HIPAA/HITRUST workloads
• Work with PHI/PII data handling standards, encryption, auditing, and compliance
• Partner with the compliance team to ensure systems support audit‑readiness

Data & Integration Engineering

• Build scalable data pipelines and workflows that power nutrient modeling, diagnostics, and personalization
• Integrate with labs, diagnostic systems, wearables, EHRs (FHIR/HL7), and third‑party health APIs
• Contribute to structuring Youtopia’s long‑term health data platform and data lake

Engineering Excellence & Collaboration

• Work closely with Front‑End, Platform, Dev Ops, Compliance, and Product teams
• Participate in architecture reviews and drive engineering best practices
• Ship high‑quality code quickly in a fast‑moving, mission‑driven environment

Who You Are

You are a builder at heart. A senior‑level engineer who:

• Thrives in modern .NET / Azure ecosystems
• Loves solving complex backend engineering problems
• Wants to build meaningful technology that improves real lives
• Is energized by autonomy, craftsmanship, and rapid iteration
• Excels in high‑performance teams with high expectations
• Gets excited about building systems intended for massive scale

Qualifications Required

• 7+ years professional experience in back‑end engineering in HIPAA applications
• Deep expertise in C# and .NET 8+
• Strong experience with Azure cloud services
• Proven experience designing and implementing microservices
• Experience with distributed or event‑driven architectures
• Solid understanding of relational database design
• Strong understanding of application security and modern API best practices
• Ability to self‑organize and take ownership in ambiguous environments
• High‑scale or real‑time system architecture

Bonus / “Superpower” Skills

• Extensive Healthcare experience (HIPAA/HITRUST, FHIR, HL7, labs, PHI workflows) building new applications
• Wearable integrations, device data ingestion, or sensor data APIs
• Data lakes, analytics pipelines, or ML integration patterns
• Experience deploying services in highly regulated environments

If you have most but not all qualifications, we still encourage you to apply.

Location

• Remote within the United States

Why Youtopia? Impact at Scale
