MDiet is a health-tech startup for the US market. Our AI platform reduces patient hospital readmissions. With the successful growth of the company, there is an opportunity for relocation/immigration to the US.
About the Role
We are looking for a strong, hands-on engineer for a Tech Lead position—one of our first backend engineers who will build our production platform from scratch.
What You Will Do
Design and develop services, APIs, and integrations (FHIR / HL7) from scratch.
Make key architectural decisions.
Lay the foundation for security and compliance (HIPAA / SOC 2).
Establish engineering practices from day one: code reviews, quality standards, and processes.
Provide technical leadership for the backend division, help the team grow, and integrate AI components (a dedicated AI Lead is responsible for the AI models themselves).
Tech Stack
Core: Java 21 + Spring Boot (main focus); additionally Python + FastAPI.
Data: PostgreSQL, Redis (vector DBs are a plus).
Architecture: Event-driven (Kafka / RabbitMQ).
Cloud & DevOps: AWS, Docker, Kubernetes, Terraform, GitLab CI/CD, monitoring (Prometheus / Grafana).
Security & API: OAuth2 / OIDC, REST / gRPC, API Gateway, HIPAA / SOC 2.
Requirements
Must-have:
Strong experience in system design and architecture—the ability to design and build complex systems from scratch (this is a key priority).
Readiness to code actively while immediately establishing processes and standards.
English (at least B2)—for documentation and verbal communication with US partners.
Nice-to-have:
Experience with vector databases.
Integration of AI services / LLMs (RAG, embeddings, tool calling).
Experience with mentorship or small-scale leadership.
Basic understanding of frontend development (how the frontend interacts with APIs).
Application Note: If you have read this job description carefully, please include the answer to the question "two plus two" in your response.
