About Abby Connect
Abby Connect is a fast-growing customer experience company helping small businesses deliver personal, professional, and scalable communication. Our live receptionist services have powered thousands of client interactions every day for over a decade, and we’re now expanding our technology portfolio with *AI-driven products* that combine human empathy with intelligent automation.
The *AI Receptionist Platform* is Abby Connect’s latest innovation — an intelligent voice system that manages scheduling, intake, and communication in natural conversation. It’s a critical part of our long-term strategy to redefine how businesses handle customer calls.
*The Role*
We’re hiring an *internal AI/full-stack engineer* to take ownership of the AI Receptionist platform.
This is a *high-impact, hands-on engineering role*, not a management or architecture-only position.
You will:
* Build, optimize, and extend our LLM-powered voice receptionist
* Own architecture _and_ implementation across backend, AI/RAG pipelines, and integrations
* Partner directly with the CEO on strategy and execution
* Review, enforce, and raise engineering quality across our outsourced team
* Ship production-grade features quickly with strong reliability and observability
* Lead and mentor future engineering hires as the team grows, setting technical direction and development standards.
*What You’ll Do*
AI / LLM Engineering
* Own RAG, vector search, retrieval quality, hallucination mitigation, and evaluation pipelines
* Integrate LLMs (OpenAI, Anthropic, etc.) with tools, memory, and business logic
* Build agent workflows and voice orchestration
* Optimize latency, cost, and accuracy at scale
Backend & Full-Stack Engineering
* Build and maintain modern, production-grade microservices
* Work primarily in *TypeScript, Python, and React*
* Improve observability, logging, monitoring, CI/CD, and test automation
* Make heavy use of queues, caching, async pipelines, and distributed systems patterns
Voice AI / Telephony
* Integrate STT/TTS (ElevenLabs, Whisper, etc.)
* Work with telephony partners (Twilio, SIP, WebRTC)
Cross-Functional & Leadership
* Work directly with the CEO & Product Manager
* Collaborate with operations, voice partners, and support teams
* Review and guide our outsourced engineering vendor (Scopic)
* Be the technical owner until future hires join
*Who We're Looking For:*
Required
* *5+ years of hands-on software engineering (not architectural-only)*
* *Experience leading engineering teams*
* Strong backend engineering foundation (TypeScript or Python)
* *Proven experience in at least 2 of the following:*
* RAG pipelines (FAISS, Pinecone, Weaviate, Chroma)
* LLM agent workflows (LangChain, CrewAI, custom)
* Vector DB design, chunking, embedding pipelines
* LLM integration & evaluation
* Experience shipping production systems (ideally v1 builds)
* Comfortable working in a fast-moving, ambiguous environment
* Strong debugging, code-review, and architecture instincts
Bonus, but very valuable
* Voice AI (ElevenLabs, Whisper, Tymeshift, Twilio Voice, SIP, WebRTC)
* Realtime or event-driven systems
* Experience at an early-stage startup
* Experience managing or improving outsourced engineering teams
This might not be for you if:
* Pure “Principal Architect,” “Lead,” or “Manager” roles with little day-to-day coding
* Anyone who hasn’t built RAG or agent systems
* Enterprise-only engineers with no startup/v1 experience
* You prefer strategy/leadership over coding
*Why Join Abby Connect*
* Impact: You’ll play a key role in the next phase of Abby Connect’s growth — driving the technology behind a product already in market.
* Stability + Innovation: We’re profitable, established, and expanding into new AI-driven lines of business.
* Ownership: Influence architectural decisions and shape how we scale our technology and team.
* Mission: We believe the future of customer service combines human understanding with AI precision.
* Collaboration: Work closely with executive leadership to bridge product, AI, and operations.
*Compensation & Benefits*
* Competitive SF-based salary: $180K–$200K
* Comprehensive health, dental, and vision insurance
* Paid holidays + flexible PTO
* Growth path into future engineering leadership
*Abby Connect’s Values*
* Human first: We build technology that amplifies human connection.
* Own the outcome: We take initiative, not orders.
* Learn fast: We test, iterate, and adapt.
* Collaborate openly: Everyone has a voice in shaping the product and company

Application Question(s):
* Are you located in San Francisco or within commutable distance? This is an in person role in our San Francisco office.
* Can you describe a recent project where you personally built and shipped an AI/LLM feature (e.g., RAG pipeline, agent workflow, LLM-integrated API)?
* Are you comfortable writing production-level code daily in either TypeScript or Python?
* Have you directly implemented vector search or retrieval-augmented generation (RAG) using tools like Pinecone, Weaviate, FAISS, Qdrant, or a similar vector DB?
* Do you have experience working in a fast-paced startup or small engineering team where you owned features end-to-end (architecture → code → testing → deployment)?
