Sapience AI is the collective intelligence platform for professional communities. We sit above the CRMs, AMS platforms, and knowledge bases that organizations already run, and we turn the expertise scattered across them into something every member can search, act on, and share.

The intelligence a community needs is already inside it. Most organizations just cannot reach it. Knowledge lives in silos, in legacy systems, in the heads of a few experts, and in fragmented records no one can connect. We change that.

Our work is grounded in four commitments: technology elevates people and never replaces them, the best expertise is already inside the community, everything is built on trust, and every deployment is purpose-driven for the organization it serves.

Let’s achieve more, together.

Where this role sits

This role owns the heart of how Sapience AI reasons. You lead the neuro-symbolic approach that combines symbolic knowledge, structure, and rules with neural and language-model capability, the approach that lets the platform reason over a community’s expertise with both flexibility and rigor.

You own the direction of the COGENT architecture: how it fuses the KO (knowledge object) graph and symbolic reasoning with neural models, how it stays trustworthy and explainable, and how it advances over time.

You lead a specialized team and partner across research, applied AI, and knowledge graph engineering to turn a hard idea into a working system at the center of MINERVA.

Why this role exists

Pure neural systems are fluent but can be confidently wrong, and they struggle to explain themselves. Professional communities cannot act on answers they cannot trust or trace. Collective intelligence needs reasoning that is both flexible and grounded.

Bringing symbolic structure and neural capability together is one of the hardest and most valuable problems in applied AI. It is also the core of what makes Sapience AI different.

The Head of Neuro-Symbolic AI owns that problem. You set the architectural direction, lead the team, and are accountable for reasoning that members can trust, trace, and act on.

What you will own (Areas of Responsibility)

You hold seven areas of responsibility across the neuro-symbolic architecture. Each one is yours to set direction on, build, and be accountable for.

1. Neuro-symbolic architecture and direction

• Own the direction of the COGENT architecture and how it fuses symbolic reasoning with neural and language-model capability.
• Set the approach to grounding, structure, and rules that keeps reasoning trustworthy.
• Decide what belongs in the symbolic layer, the neural layer, and the seam between them.

2. Reasoning over the knowledge graph

• Own how COGENT reasons over the KO graph to turn a community’s expertise into answers members can act on.
• Partner with knowledge graph engineering on the structures reasoning depends on.
• Advance retrieval, inference, and symbolic reasoning together, not in isolation.

3. Trust, explainability, and provenance

• Make reasoning explainable and traceable, so members can see why the platform says what it says.
• Build the guardrails and provenance that let communities trust and verify answers.
• Reduce confident errors, and handle uncertainty honestly.

4. Research direction and applied advances

• Set the research agenda for neuro-symbolic methods at Sapience AI.
• Decide which advances are ready for production and which need more work.
• Keep the approach current with the field without chasing every trend.

5. Team leadership

• Build and lead a specialized team of researchers and engineers.
• Set a high bar for rigor and for shipping, and hold both.
• Grow the people who will define this area for the company.

6. Productionization with platform and applied AI

• Partner with platform and applied AI to run neuro-symbolic reasoning reliably and affordably in production.
• Balance ambition against the constraints of latency, cost, and scale.
• Turn architectural advances into dependable behavior in MINERVA.

7. Evaluation and measurement

• Own how the quality of reasoning is measured, including accuracy, groundedness, and trust.
• Build evaluation that reflects what communities actually need, not just benchmark scores.
• Use evidence to steer the architecture’s direction.

AI-augmented ways of working

You lead work at the frontier of applied AI, and you use AI throughout it, to explore approaches, run experiments, and reason about results, while holding the rigor that this domain demands.

The standard is human in partnership: AI accelerates the work, you own the judgment, the interpretation, and the call. The people who create the most value here are not the ones producing the most output. They are the ones turning evidence into clear, durable decisions.

What this role is not

To keep the boundary clear:

• This is not a pure research role. You are accountable for reasoning that works in production, not only for publications or prototypes.
• This is not a general engineering leadership role. You own the neuro-symbolic architecture specifically, in partnership with the broader engineering organization.
• This is not a knowledge-graph-only role. You own reasoning over the graph and its fusion with neural methods, partnering with graph engineering on the structures.
• This is not a benchmark-chasing role. You are measured on trustworthy reasoning members can act on, not leaderboard scores alone.

What success looks like

We measure this role on outcomes the team can see:

• Trustworthy reasoning. The platform reasons over community knowledge in ways members can trust, trace, and act on.
• A working architecture. COGENT advances as a real system in production, not just on paper.
• Explainability. Answers carry provenance, and confident errors go down over time.
• A strong team. You build a group that sets the standard for this work.
• Production-ready advances. Research turns into dependable behavior at acceptable cost and latency.
• Honest measurement. Reasoning quality is measured against what communities actually need.
