Senior Software Engineer (Python)
Project Overview
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.
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.
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
Team Composition:
Software Engineer, QA Engineer, UI-UX Designer, DevOps Engineer, Product Manager, Delivery Manager
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.
Qualifications
- 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.
- Experience with Python async frameworks and async/await patterns.
- Familiarity with PostgreSQL or relational databases.
- Prior experience in a lead or mentorship role.
- GitHub-based workflows and conventional commits.
