Senior Ontology & Semantic Systems Architect

This role begins as equity-based until funding closes Q1 2026**

About BlackFrost

BlackFrost is building the world’s first Infrastructure Intelligence Utility™, enabling real-time physical-world understanding through our two core systems:

• AuralisIQ™ – sensor telemetry infrastructure

• FrostBase™ – our semantic layer that converts raw signals into primitives → events → states

We’re creating a new class of intelligence for the physical world — and we’re looking for a Senior Ontology & Semantic Systems Architect who can help operationalize FrostBase’s structure at the engineering level.

This is a high-impact, architecture-driven role for someone who loves imposing order, consistency, and semantics on complex, real-world systems.

You join as part of the founding technical team and transition into full salaried compensation immediately after the raise.

The Role: Senior Ontology & Semantic Systems Architect (FrostBase)

You will translate our conceptual PSAI architecture into a formal, usable, engineering-ready semantic system.

Your responsibilities include:

What You’ll Own

• Define FrostBase’s primitive schema

• Create and maintain event definitions state transition rules

• Design the internal semantic data model / FrostGraph representation

• Build documentation, standards, and canonical structures for engineering

• Work with AuralisIQ engineers to map raw telemetry → normalized primitives

• Work with AI engineers to operationalize primitives → inference pathways

• Ensure FrostBase remains consistent, scalable, and implementation-ready

• Act as the “semantic backbone” between telemetry, AI, and product teams

This is NOT a research-heavy ontology PhD role.

It is a practical engineering semantics architecture role.

Who You Are

You thrive at the intersection of:

• structured data modeling

• distributed systems

• semantics schema design

• event-driven architecture

• knowledge representation

• organizing complex, messy world data into logical frameworks

You may have backgrounds in:

• systems architecture

• data modeling

• IoT / telemetry systems

• knowledge graphs (applied, not academic)

• event-stream processing

• semantic modeling inside enterprise or industrial systems

You’re obsessed with:

• clarity

• structure

• consistency

• frameworks

• building semantic standards from scratch

• turning ambiguity into an organized model

If you think in diagrams, schemas, and structured representations — you will love this role.

Location Requirement

You must live within 3 hours of Dayton, Ohio

(Cincinnati, Columbus, Indianapolis, Louisville, Lexington, etc.)

This role is hybrid and requires periodic in-person collaboration with our executive and engineering leadership team as we build FrostBase, stand up AuralisIQ infrastructure, and engage with university research partners.
