155. Tech Lead

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.

✔ Benefits package focused on health and well-being 
✔ Competitive salary based on experience
