Solution Architect (Digital Health / Cloud)

About the company

You will join a team building a cloud and application ecosystem that supports people with diabetes and healthcare professionals.

Your tasks

The portfolio includes, among others

• a patient mobile app (Flutter) with related backends and device cloud sync
• a web platform for clinics and healthcare staff
• an identity service — accounts, consents, age verification
• a health-data service — storage and APIs
• blood glucose meter integrations, cloud sync, legal consents, i18n

You will work closely with Product, Engineering, and DevOps on end-to-end architecture in a regulated environment (medical / PHI data). Direct client engagement — workshops, architectural decisions, and technical communication with business stakeholders.

• Design and evolve solution architecture across the diabetes-care ecosystem (mobile, clinical web, identity, health data)
• Keep contracts and flows consistent across services (identity, country/localization config, PHI, clinical platform, notifications, device/sync)
• Drive architectural decisions: APIs (REST/GraphQL), data (SQL / Cosmos), messaging, storage, identity
• Design and oversee the cryptography layer: asymmetric encryption (RSA), symmetric encryption, key management, data protection at rest and in transit, tokens / wallets / storage credentials
• Own NFRs: security, privacy, multi-region, scalability, observability
• Support integrations: meters / BT pairing, device cloud sync, legal consents, identity verification, translation workflows
• Analyze E2E production/test incidents (sync, pairing, storage, cryptography) and recommend fixes
• Collaborate with .NET, FE (React), mobile (Flutter), QA, and Azure infrastructure teams
• Produce architecture docs, ADRs, and requirements for epics / changes
• Support pipelines and environments: dev / test / stage / prod

Requirements

• Experience as a Solution Architect / Senior Software Architect on complex distributed systems
• Strong .NET / ASP.NET Core and microservices architecture skills
• Hands-on Azure (App Services/Functions, SQL, Cosmos DB, Service Bus, Storage, Key Vault, APIM, App Insights)
• Experience with APIs (REST and/or GraphQL) and data modeling (relational + document)
• Knowledge of OAuth2 / OpenID Connect (IdentityServer or equivalent)
• Solid applied cryptography: RSA, symmetric algorithms, key management, TLS, protecting sensitive data
• Ability to design for sensitive data (privacy, consents, retention, audit)
• Experience diagnosing E2E issues (logs, telemetry, request correlation)
