About Limina

Limina is the contextual data intelligence platform built for the AI era. Evolved from Private AI, the world's most accurate PII and PHI de-identification engine, Limina has expanded into a full platform play that governs sensitive data across the entire enterprise AI lifecycle: from classification and redaction through to agentic workflows, RAG pipelines, and real-time data security.

Brands like RBC, Deepgram, and Boehringer Ingelheim already rely on our platform to build on, govern, and deploy AI against their most sensitive datasets. We've been recognized as a Gartner® Cool Vendor™ in Privacy and a World Economic Forum Technology Pioneer, and we’re backed by investors in Toronto, New York, Seattle, and San Francisco. 

What is the opportunity

As a Junior Software Developer at Limina, you'll join our engineering team building and maintaining the services that power our data privacy platform.

What does the day to day look like?

Our platform is built from independently deployable services, including a web API layer and a configurable background processing system, along with shared code for data models, caching, and job handling.
