We are looking for a Senior Backend Engineer to build and deploy a Python-based middleware service that securely integrates the mobile application with external AI services for voice and text analysis. You will architect backend services that handle token exchange, API key management, and data flow between the patient mobile app, AI analysis services (voice and text), and the EHR backend system. This role requires strong Python backend expertise, experience with containerized deployments, and an understanding of secure authentication patterns in healthcare systems.

Our client is a mental health platform that combines mobile technology with AI-powered therapy support. Patients record voice journal entries through a mobile app, which are analyzed by AI to help therapists identify the most effective treatment strategies for each individual. The approach is rooted in Cognitive Behavioral Therapy (CBT), helping patients change thinking patterns and develop healthier behaviors through guided problem-solving and relaxation techniques. The platform connects patients with therapists through HIPAA-compliant mobile and web interfaces.

Technical Details:

• Backend: Python 3.x, RESTful APIs
• Authentication: OAuth 2.0, JWT, token-based flows
• External APIs: Voice analysis service, text/chat analysis AI service, EHR system API
• Security: API key management, secure secrets handling, TLS, HIPAA compliance
• Containerization: Docker, Kubernetes (K8s)
• CI/CD: GitLab CI/CD, GitHub Actions, or similar
• Infrastructure-as-Code: Helm, Terraform, or similar
• Cloud Platform: Digital Ocean
• Monitoring & Observability: Prometheus, Grafana, ELK stack, or similar‍
• Project Management: Linear

Job Highlights:

• Build HIPAA-compliant backend infrastructure for behavioral health platform.
• Design a secure middleware architecture that prevents API key exposure in mobile apps.
• Work with modern AI services for voice and text analysis in the mental health domain
• Real-world impact supporting patient-therapist communication and mental health outcomes

Workflow:

• Secure middleware service: Design and build a Python backend service that acts as a secure proxy between the React Native mobile app and external AI services (voice analysis for ~40-second audio clips, text analysis, and chatbot services for journal entries), preventing API key exposure in the public mobile client
• Token exchange and authentication: Implement OAuth 2.0 flows and token management to accept access tokens from the mobile app, use them to post analysis results to EHR backend on behalf of users, and return results to the mobile app (MVP approach: token passthrough; future: proper OAuth client implementation)
• API integration and data formatting: Develop REST endpoints to receive voice and text data from mobile app, package and format data for external AI service APIs (batch uploads for voice, conversational flow for text), receive processed analysis responses, and forward results to EHR backend
• Security and rate limiting: Securely manage API keys and secrets (storage, rotation, access control), implement server-side rate limits and anomaly detection, configure TLS with certificate pinning support, and set up monitoring to prevent abuse of paid AI services‍
• Mobile integration support: Collaborate with Mobile Engineer (React Native) to define API contracts, understand mobile app architecture and data flow requirements, and implement backend endpoints that support mobile workflows

Responsibilities:

• Design and implement a Python backend middleware service with RESTful APIs that securely proxy requests between mobile apps and external AI services (voice and text analysis), handling data formatting, token exchange, and API key protection.
• Integrate with external AI services and EHR backend, implementing OAuth 2.0 token flows, secure secrets management, and error handling for third-party API failures and rate limits.
• Implement security controls, including HIPAA-compliant data handling, server-side rate limiting, anomaly detection, TLS configuration, and audit logging.
• Collaborate with Mobile Engineer on API contracts and integration patterns, participate in code reviews and architecture decisions, and write tests for backend services.

• 5+ years of professional backend development experience with strong Python expertise.
• Experience using AI-powered productivity tools (Cursor, VS Code with Copilot, or similar AI-enhanced IDEs) and LLMs for research and problem-solving (ChatGPT, Claude, etc.).
• Proven experience designing and building RESTful APIs and backend services in production environments.
• Solid understanding of OAuth 2.0, JWT, and token-based authentication flows.
• Strong knowledge of HTTPS, TLS, REST API security, and secure communication patterns.
• Experience integrating with third-party APIs and handling external service errors, rate limits, and retries.
• Strong problem-solving skills and ability to work autonomously with minimal oversight.
• Clear written and spoken English for async collaboration and documentation.

Nice to Have

• Understanding of HIPAA compliance requirements or healthcare data handling (bonus: prior healthcare/telehealth experience).
• Experience with the FastAPI framework specifically.
• Experience integrating AI/ML services (speech analysis, NLP, chatbots, LLM APIs).
• Experience building backend APIs for mobile applications (iOS/Android) and understanding mobile-specific constraints.
• Familiarity with rate-limiting strategies, anomaly detection, and abuse prevention patterns.
• Background in telehealth, mental health, or healthcare technology platforms.
