The role emphasizes production-quality code, strong debugging, and collaboration via GitHub. Competitive rewards and healthcare coverage accompany career growth and inclusive culture.

Qualifications

• Strong professional experience in Python and the ability to work effectively in a mature production codebase.
• Full-stack development experience, including backend development, databases, HTML/CSS, and JavaScript.
• Practical experience with Flask or a comparable Python web framework.
• Experience with relational databases, SQL, ORM-based development, and schema migrations.
• Experience integrating third-party APIs and troubleshooting authentication, webhooks, timeouts, retries, and malformed responses.
• Working knowledge of AWS and containerized application environments.
• Strong Git/GitHub practices and experience creating focused, reviewable pull requests.
• Demonstrated proficiency with AI-assisted software development using tools such as GPT/ChatGPT, Codex, Claude Code, or Cursor.
• Experience with asynchronous processing, including SQS, Redis, background workers, or similar systems.
• Experience with Playwright or browser automation.
• Experience with LLMs, agentic applications, tool calling, prompt-driven workflows, or voice AI.
• Experience working with healthcare software, EHR/FHIR integrations, security-sensitive applications, or other regulated environments.
• Strong troubleshooting skills across application logs, queues, external APIs, and databases.
• Ability to independently validate AI-generated code and apply sound engineering judgment, security awareness, and quality standards.
• Strong written communication skills and the ability to clearly explain technical changes, testing performed, and potential risks.
• Comfortable taking ownership of production issues from diagnosis through resolution.

Responsibilities

• Build and deliver end-to-end product features across Python/Flask backend services, Jinja templates, JavaScript interfaces, database models, APIs, and third-party integrations.
• Develop and maintain agentic workflows connecting web applications with AI and voice systems, webhooks, queues, EHR/CRM platforms, and browser automation.
• Work within an existing production codebase, quickly understand unfamiliar code, follow established conventions, and implement pragmatic improvements without unnecessary rewrites.
• Design, integrate, and troubleshoot REST APIs, OAuth flows, webhooks, retries, idempotency, background jobs, and external-service failure handling.
• Manage PostgreSQL data, SQLAlchemy models, Alembic migrations, Redis, and asynchronous processing while maintaining data integrity.
• Develop and maintain automated tests using pytest and existing testing patterns to reduce regression risks.
• Diagnose application and integration issues using production and staging logs and monitoring tools such as CloudWatch.
• Collaborate through GitHub pull requests, automated testing, linting, staging validation, and production release workflows.
• Use modern AI engineering tools to understand code, plan and implement changes, generate tests, investigate failures, review code, and improve development productivity.
• Own production issues from investigation through resolution while continuously improving system reliability and developer velocity.
