Laboratory Data Ontologist (Remote)

Laboratory Data Ontologist Remote | Canada or US Overview We are seeking a Laboratory Data Ontologist to strengthen the semantic foundation of our platform and the client-specific ontologies deployed on top of it. Labbit is built on a typed entity graph — samples, containers, locations, instruments, pools, and their provenance — and every implementation is, at its core, a modelling exercise: mapping a client's scientific and operational vocabulary onto that graph without losing fidelity. This role sits within our Advisory group. You will spend ~50% of your time billable on client implementation projects as the modelling lead, and the remaining ~50% on internal stewardship — evolving the core ontology, codifying modelling practice, and supporting Sales pursuits. This is not a data engineer role and not a solutions architect role. You are a modeller — steeped in information theory, taxonomy design, and ontology engineering — whose primary deliverables are client and platform ontologies, reference models, and the standards that govern them. Why This Role Matters Our platform's differentiator is a configurable, versioned entity graph with immutable lineage. That model is only as valuable as the discipline behind it: Advisory engagements deepen when modelling is treated as a first-class deliverable rather than a byproduct of configuration. Sales wins when we can quickly show a prospect their world represented cleanly in our model. Implementation delivers faster when client vocabulary maps to reusable patterns instead of bespoke types. Platform evolves coherently when extensions across clients are legible as variants of shared abstractions rather than divergent one-offs. Housing this role in Advisory keeps the practitioner close to real client problems — the billable work is where modelling craft is sharpened — while the non-billable half compounds those learnings into shared assets the whole company draws on. What You Will Do 1. Lead Modelling on Client Engagements (~50% billable) Serve as the modelling lead on Advisory and Implementation engagements where ontology depth is the critical risk Run discovery sessions to elicit and structure client domain models Produce target ontologies — entity types, controlled vocabularies, field taxonomies, workflow decompositions — as billable deliverables Review changeset designs for modelling quality alongside implementation engineers Coach client counterparts on stewardship of their own model post go-live 2. Steward the Core Ontology Own the conceptual model behind Labbit's base entity types (@Sample, @Container, @Location, @Instrument, @Reagent, @Pool) and their inheritance semantics Maintain design principles for when to extend a base type vs. introduce a new one Review proposed changes to the base ontology for coherence, minimalism, and long-term extensibility Curate the shared reference/IRI namespace so aliases remain meaningful across changesets and clients 3. Codify Modelling Practice Across Advisory Author internal standards for taxonomy design, controlled vocabulary governance, and ontology versioning Identify reusable extension patterns across client engagements and promote them into shared libraries Establish review rituals so modelling decisions are traceable and reversible Train Advisory and Implementation staff in applied ontology techniques Build a shared library of domain reference models for our priority verticals (QC manufacturing, clinical genomics, CGT, stability) 4. Support Sales Join late-stage sales cycles to lead ontology discovery sessions with prospects Produce lightweight target models that demonstrate fit without over-committing to configuration Translate prospect terminology (assays, panels, batches, lots) into our model in real time during demos 5. Inform Platform Direction Surface modelling gaps discovered across client work as candidate platform investments Advise Platform Engineering on schema evolution semantics (changeset migrations, deprecations, aliasing) Contribute to decisions about first-class vs. reference-data entities, computed fields, and graph traversal features What You Will Not Do Own application development or feature delivery Serve as project manager or delivery lead on client engagements Replace implementation configuration engineers or platform engineers Build a parallel modelling framework outside our changeset system Qualifications Required Strong grounding in information theory, formal ontology, or knowledge representation (academic or applied) 5+ years working with structured domain models — taxonomies, controlled vocabularies, ontologies, or graph schemas — in production settings Fluency with at least one modelling formalism (OWL/RDF, property graphs, UML class models, ISA-Tab, or comparable) Demonstrated ability to elicit domain knowledge from subject-matter experts and translate it into a coherent model Comfort in a client-facing, billable advisory context — including scoping deliverables, running workshops, and defending modelling decisions to technical and non-technical stakeholders Comfort reading and reasoning about configuration-as-code artifacts (JSON schemas, BPMN, expression languages) Excellent written communication — you will produce reference models, standards, and documentation that others rely on Strongly Preferred Experience in laboratory informatics, life sciences, or another regulated scientific domain (QC manufacturing, genomics, clinical diagnostics, CGT) Familiarity with LIMS, ELN, or scientific workflow platforms and their data models Experience with versioned schema evolution and immutable/provenance data models Exposure to regulated environments (21 CFR Part 11, GAMP5) and their implications for schema governance Prior consulting or professional services experience with utilization targets To further support our team, we offer the following benefits: Competitive vacation Flexible health spending account / Health Insurance RRSP / 401 K matching Annual professional development budget The expected salary range for this role is: $150,000 - $190,000 CAD or USD Actual compensation may vary based on experience, domain expertise, and geographic location.
