About the Job
- Design, build, and operate production AI-powered systems and agentic experiences (including Cart Assistant and voice AI) that directly impact how millions of customers shop.
- Build foundational systems for cutting-edge AI experiences, ranging from embedding infrastructure and voice AI pipelines, to client facing components and integrations, by prototyping bold ideas and productizing what works.
- Integrate foundation models via APIs and open-source frameworks; apply techniques like retrieval-augmented generation and vector search where appropriate.
- Own projects end-to-end: requirements, technical design, implementation, testing, deployment, observability, and iterative improvement focused on reliability, latency, and cost efficiency.
- Collaborate with cross-functional partners in product, design, data science, and infrastructure to ship AI features end-to-end.
- Drive engineering excellence, including thoughtful system design, rigorous code review, and technical leadership that includes defining and promoting best practices for AI/ML production engineering across the team.
About You
- Proven senior software engineer who has built, shipped, and operated production systems at scale. You make architectural calls, own what you build, and deliver through ambiguity.
- Hands-on experience with AI or ML in production. You've shipped LLM-powered features or integrated foundation model APIs into a live product, demonstrating the necessary expertise at the intersection of robust software engineering and deep production ML.
- Experience owning services end-to-end, including CI/CD, automated testing, observability (logging, metrics, tracing), and on-call participation.
- Strong communicator who partners well across disciplines - you want to get to the right answer, not just defend the first one.
- Excitement and ability to leverage cutting-edge development tools, including AI assistance (e.g., Copilot, Cursor, Claude), to maximize velocity.
About You
- 5 to 8+ years of industry experience.
- A track record of 0-to-1 work taking unconventional ideas from prototype through rapid iteration to production.
- Experience building conversational agents, multi-turn dialogue systems, or agentic LLM applications.
- Experience with STT/TTS or natural language interfaces, LLM fine tuning, ML transfer learning, model training and the vocabulary of measurement of model performance.
- Experience with embedding systems, vector search, or retrieval-augmented generation (RAG) with vector databases (e.g., Pinecone, Weaviate, FAISS, or Elasticsearch).
- Experience with cloud platforms (AWS or GCP), containers (Docker), and orchestration (Kubernetes).
- Experience with event-driven or distributed systems (e.g., Kafka).
- Demonstrated mentorship and technical leadership within cross-functional teams.
