Senior AI Engineer (Core) - Supernal

Supernal helps small-to-medium businesses hire their first AI employee. 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.

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.

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-taking, interruption handling, latency tuning, and QA for natural conversations.

Agent evaluation + reliability: Offline/online evals, regression suites, red-teaming, monitoring, and rollout controls so agents are trustworthy in production.

Production agent infrastructure: Scalable orchestration patterns for multi-step jobs, background tasks, and user-facing interactions (sync + async), with clear SLAs/SLOs.

Tooling + developer experience: Libraries and primitives that make it easy for the team to build new agent capabilities quickly and safely.

Strong software engineering fundamentals (design, testing, code quality, performance, security).

Production experience deploying AI systems in front of users (not just notebooks/demos).

Experience building agentic or LLM-powered systems with memory and tool use .

Comfort working across application + infrastructure layers: APIs, background jobs, data stores, and deployment.

Hands-on experience with at least one agent framework (or equivalent custom implementation), such as: LangChain / LangGraph LlamaIndex AutoGen / CrewAI-style multi-agent patterns

LangChain / LangGraph

LlamaIndex

AutoGen / CrewAI-style multi-agent patterns

Strong understanding of retrieval and vector search concepts: embeddings, indexing, filtering, evaluation.

Experience with vector databases and/or search stacks (e.g., Pinecone, Chroma, Weaviate, Qdrant, pgvector).

Experience designing evaluation systems (offline eval, human eval loops, production monitoring, prompt/model regression).

Experience building voice/real-time systems (streaming, WebRTC or similar), and/or integrating speech (STT/TTS) into production applications.

Experience building durable, long-running workflows (Temporal or similar orchestration engines).

Familiarity with observability tooling (OpenTelemetry, Datadog, or similar).

Experience shipping multi-tenant SaaS systems with strong privacy boundaries.

System design for agentic applications (state, memory, evaluation, failure modes).

Practical retrieval/RAG design (data modeling, indexing, relevance, latency).

Production engineering practices (testing strategy, observability, rollouts).

Ability to communicate tradeoffs and make good technical decisions under uncertainty.
