Source Meridian

We’re looking for a Tech Lead (Python - React) to join Source Meridian. About Source Meridian Source Meridian is a development software company that works to solve the industry’s most challenging problems in healthcare practices. We are laser focused on specific technologies in the healthcare and life science industries: Healthcare technology, artificial intelligence, and healthcare interoperability. About the Role You own the architecture, the standards, the review process, and the quality bar. You don't write most of the feature code — you define the contracts and boundaries that everyone else builds against, you review every PR that touches financial logic or PHI, and you make sure nothing merges that shouldn't. You are the person CTO trusts to keep the platform correct while five people build in parallel. What You’ll Do - Produce the complete module scaffold: interface contracts for all 14 modules, SQLAlchemy base classes (including TenantScopedModel for tenant isolation), import-linter configuration, and CI/CD pipeline (Azure DevOps). - Author the coding standards document that every AI-assisted prompt must reference. - Define the spec-driven development workflow: spec templates for financial/compliance modules, test-first generation process, spec approval gates. - Set up the Golden Set validation suite framework (35 real cases + CMS published examples) for the repricing engine. - Own the PR review process. You are the primary reviewer for: interface contract compliance, tenant isolation correctness (RLS + application-layer), and financial logic validity. - Co-own the spec review process with domain authorities. You review specs for completeness of edge cases, boundary conditions, and error handling before any code is generated. - Own test strategy and infrastructure: Golden Set suite, cross-tenant RLS test battery, state machine transition test matrix, automated PHI pattern scanning in CI/CD. - Manage PR queue health. Work with PM to keep queue depth manageable. Delegate lower-risk PR reviews to Senior Engineer. - Serve as the architectural decision-maker. Any decision touching module boundaries, data model changes, or security controls goes through you. - Produce architectural documentation: decision logs, interface contract updates, technical debt register. Required Qualifications - Python 3.12+ / FastAPI — deep, not just familiar. - PostgreSQL — including Row-Level Security, connection pooling session variable management, JSONB indexing (GIN), and SQLAlchemy 2.0 async patterns with Alembic migrations. - Architectural governance - Test strategy for financial systems - Azure — Container Apps, Service Bus (dead-letter handling, retry configuration), Blob Storage, Key Vault, Application Insights. - AI-assisted code review - HIPAA / PHI awareness. Healthcare domain experience is a strong plus but not required if you have experience with similarly regulated environments (financial services, PCI-DSS). - English B2+ - C1 Nice to Have - React SPA experience (the internal workbench is React 18 / Vite). - Experience with spec-driven or contract-first development workflows. - Anthropic Claude API or Azure OpenAI integration experience. Soft Skills - Strong and empathetic leadership. - Proven client-facing experience. - Excellent communication skills. - Strong expectation management abilities. - Strategic mindset with a solution-oriented approach and strong decision-making skills.

Role Description We’re looking for a Senior Full Stack Developer (Python - React) to join Source Meridian. You are the builder. You work directly alongside the domain experts, co-write the most critical and risk-sensitive modules, build the test infrastructure, and handle the complex backend work that requires deep engineering skill — not just domain knowledge and an AI prompt. You also serve as the second PR reviewer, taking load off the Tech Lead for lower-risk PRs so the review queue doesn't become a bottleneck. What You’ll Do - Co-build the platform scaffold: PostgreSQL schema (core entities, tenant-scoped tables, RLS policies), FastAPI project structure, Entra ID auth integration, Azure Service Bus queue setup. - Implement the TenantScopedModel base class and write the first RLS test battery. - Load and validate the CMS MPFS fee schedule (ETL pipeline from CMS fixed-width files into PostgreSQL). - Set up the local development environment (Docker Compose: PostgreSQL, Redis, Service Bus emulator) and document it. - Repricing engine: Write the Medicare RVU calculation core (hlh-repricing-core package). This is the single most sensitive component in the platform — pure deterministic function, zero external dependencies, unit tests for each of the five calculation steps independently. This is not AI-generated. You write this by hand. - Tenant isolation layer: Implement and test the dual-control pattern (application-layer TenantScopedModel + PostgreSQL RLS with set_config on connection checkout/checkin). Write the cross-tenant test battery that runs in CI on every PR. - State machine transitions: Implement the custom state machine (14 states, WorkflowTask table, SLA polling job). - Service Bus workers: Build the worker infrastructure (OCR jobs, packet generation, sync adapters). Ensure idempotency, dead-letter handling, and forward-compatible message schemas for rolling deployments. - PHI automated controls: Implement the CI/CD PHI pattern scanner, the runtime outbound payload filter for LLM API calls, and the continuous log monitoring queries. - Review PRs that the Tech Lead delegates: UI components, Service Bus worker handlers, non-financial data pipeline code, Dynamics sync adapters. - You review for: module boundary compliance, idempotency, error handling, and test coverage. The Tech Lead retains final authority on financial logic and tenant isolation PRs. Qualifications - Python 3.12+ / FastAPI - PostgreSQL — advanced. RLS policies, SQLAlchemy 2.0 async, Alembic migrations, JSONB with GIN indexing, connection pool lifecycle management. - Azure Service Bus — message handling, dead-letter queues, retry with exponential backoff, idempotent consumer patterns. - Test-driven development - Azure — Container Apps, Blob Storage (pre-signed URLs, lifecycle policies), Key Vault, Application Insights structured logging. - React — solid working knowledge. - AI-assisted code review. - CI/CD pipeline engineering — Azure DevOps Pipelines. - English B2+ - C1 Requirements - Healthcare domain experience or HIPAA-regulated environment experience. - Anthropic Claude API integration (structured JSON extraction, prompt engineering for schema-conformant output). - Azure Form Recognizer / Document Intelligence experience. - Experience with financial calculation engines (fee schedules, pricing models, audit trail requirements). Soft Skills - Proven client-facing experience. - Excellent communication skills. - Strong expectation management abilities. - Strategic mindset with a solution-oriented approach and strong decision-making skills.
