Profound is on a mission to help companies understand and control their AI presence. As an AI / ML Engineer, you will design, build, and ship large scale NLP and LLM systems that power classification, ranking, clustering, topic discovery, and content generation. You will own workflows from data to deployment, partner across product and engineering, and turn real user conversations into production features and publish-ready content that drives visibility, engagement, and conversion.

What You’ll Do

Build and deploy NLP models at scale for classification, ranking, clustering, topic extraction, and summarization

Design LLM workflows for context and content generation end-to-end : topic discovery → brief creation → outlines / drafts → revision loops → publish-ready assets

Develop prompt and template libraries aligned to brand voice and channel (blog, landing pages, help docs, ads), with retrieval for evidence-grounded generation and citations

Create eval frameworks for generated content (factuality, coverage, tone, safety, originality) with rubric-based LLM evals, human-in-the-loop review, and red-teaming

Instrument content performance (AEO / SEO visibility, engagement, conversion) and run experiments to improve quality, cost, and latency

Transform large text datasets into production features and signals that drive product insights

Partner with engineering to instrument events, maintain data pipelines, and uphold high data quality and observability

Collaborate with product, data, and go-to-market on success metrics and experiments that move customer-facing KPIs

What We Expect from You

Proven experience shipping ML systems in production at scale, especially with large text data

Hands-on experience building LLM content systems (prompting, templating, retrieval / RAG, guardrails, evals)

Fluency in SQL and strong Python skills with modern ML tooling

Strong grasp of ML and generation quality metrics; ability to design offline / online evals and monitoring

Ability to innovate when off-the-shelf doesn’t fit the problem

Experience working in cross-functional, high-performance teams

Clear communication with technical and non-technical partners

Ownership mindset and comfort operating in a fast-paced environment

What You’ll Get Out of It

Ownership of the entire product analytics function at an early stage company

A key role in shaping how we measure usage and make product decisions

Close collaboration with product, engineering, and go to market teams

A fast paced environment with a lot of trust and autonomy

Competitive compensation and meaningful equity
