Your work will directly impact client operations by delivering scalable AI applications that solve real-world business challenges across healthcare, hospitality, professional services, e-commerce, and field operations.
Key Responsibilities
- Translate written technical specifications into fully deployed AI systems, owning the process from architecture through production handoff.
- Design end-to-end system architectures, including data flow, orchestration logic, storage, service boundaries, and failure handling.
- Build LLM-powered applications such as conversational agents, Retrieval-Augmented Generation (RAG) systems, structured extraction pipelines, and multi-agent workflows.
- Develop voice AI and telephony solutions using platforms such as Retell AI, Twilio, and real-time STT/TTS pipelines.
- Design robust prompt architectures, structured outputs, guardrails, and production-ready AI workflows.
- Build supporting infrastructure including vector databases, SQL/NoSQL databases, schedulers, queues, and containerized services.
- Integrate third-party platforms through REST APIs, OAuth, SDKs, webhooks, and legacy business systems.
- Develop data ingestion, transformation, normalization, and enrichment pipelines for production AI systems.
- Connect AI applications with CRMs, scheduling platforms, billing systems, practice management software, document repositories, and e-commerce platforms.
- Ensure secure credential management, secrets handling, and access control across environments.
- Build reliable production systems with logging, monitoring, retries, testing, evaluation frameworks, and observability.
- Optimize AI performance, latency, token consumption, and overall system cost efficiency.
- Troubleshoot and resolve production issues while performing root cause analysis for live client environments.
- Manage multiple concurrent client implementations while providing clear asynchronous progress updates.
- Produce technical documentation, architecture diagrams, deployment guides, runbooks, and system handoff documentation.
Must-Have Qualifications
- 3+ years of experience as an AI Engineer, Systems Architect, Full-Stack Developer, Automation Engineer, or similar role.
- Proven experience delivering production-ready AI systems from design through deployment.
- Strong Python development skills, including asynchronous programming and maintainable software architecture.
- Experience building applications using OpenAI, Anthropic, or similar Large Language Model APIs.
- Hands-on experience implementing RAG pipelines, embeddings, vector search, and retrieval optimization.
- Experience designing multi-agent workflows, orchestration frameworks, and tool-calling architectures.
- Strong knowledge of REST APIs, OAuth, SDK integrations, authentication, pagination, rate limits, retries, and idempotency.
- Experience deploying applications using Docker, cloud platforms (GCP or equivalent), CI/CD pipelines, and secrets management.
- Solid understanding of SQL, NoSQL databases, JSON transformation, schema design, and data engineering principles.
- Experience using Git and following software engineering best practices.
- Ability to independently deliver projects from written specifications with minimal supervision.
- Strong written English communication skills in an asynchronous remote environment.
Preferred Qualifications
- Experience with HIPAA-compliant or other regulated environments.
- Experience building Voice AI
