Our AI teammates are built using intelligent, agentic workflows deployed on a proprietary platform. We deliver working, value-generating AI Employees—not tools—that handle real business processes alongside human teams. The Role We’re hiring a Senior AI Engineer to build and ship the first generation of personalized, self-improving agentic workflows that users rely on daily. This is an “end-to-end” role: you’ll design the agent runtime, memory + retrieval systems, evaluation harnesses, and the product-facing surfaces that put agents in front of real users at scale. You should be equally comfortable reasoning about distributed systems and data (latency, caching, queues, failure modes, cost) as you are with modern agent stacks (tool use, memory, RAG, multi-step planning, guardrails, and evaluation). This role will partner closely with platform engineering to leverage and extend our core services (Django backend, event-driven systems, Kubernetes, observability) while owning critical parts of the AI application layer. What You’ll Build Personalized agent runtime: Agentic workflows that adapt to a user’s preferences, data, and ongoing behavior over time. Memory & retrieval systems: Short/long-term memory, durable state, and retrieval pipelines across vector DBs and relational data. Voice experiences (real-time + async): Speech-to-speech/voice agents, streaming audio pipelines, turn
