Senior Backend Engineer for Health-Tech SaaS

We are seeking an experienced, senior-level backend engineer to help build the core data processing architecture for a health-tech compliance and verification SaaS platform. The core of this project involves constructing a secure, robust data-ingestion pipeline that queries multiple external data sources, orchestrates API workflows, and evaluates complex data sets with high precision. Key Responsibilities: • Design and implement secure backend data pipelines and workflows. • Integrate and orchestrate multiple external third-party RESTful APIs. • Implement structured conditional logic and scoring matrices to process incoming data payloads. • Optimize database queries for low-latency lookups and updates. • Ensure data architecture adheres to high security and encryption standards. Required Technical Skills: • High proficiency in backend languages (e.g., Python, Node.js, or Go). • Extensive experience with API orchestration, handling asynchronous requests, and error-handling routines. • Strong database management skills (PostgreSQL, MySQL, or similar). • Experience writing clean, well-documented, test-driven code. • Familiarity with healthcare data security standards; ability to design backend infrastructure aligned with standard HIPAA technical safeguards (secure access controls, audit logs, and data encryption at rest and in transit). Project Type & Workflow: This will be a milestone-based, fixed-price project. We have completed the full system architecture blueprints and logical flowcharts. IP & NDA Requirement: Intellectual property protection is paramount for this project. Candidates will be required to sign a standard Non-Disclosure Agreement (NDA) with an Intellectual Property Assignment Agreement before we share the detailed technical specifications, algorithm logic, or system diagrams. If you are a disciplined backend engineer who takes pride in building secure, high-performance data workflows, please submit your proposal with a brief summary of your experience handling complex API pipelines and secure environments.
