Sightly is a growing technology company leading the revolution in real-time marketing and brand intelligence. Join us as we pursue our disruptive mission to empower businesses everywhere to make the most authentic + profitable decisions in real time.
Our AI-driven Brand Mentality® platform enables brands and agencies to leverage an ever-changing ocean of news, premium publisher, CTV, social, creator, and audience data to make more intelligent decisions at the speed of culture. At Sightly, we’re passionate about our product, our customers, our impact on the world, and most importantly our team.
What you’ll work on:
Enrichment models across our cultural data pipeline: entity extraction, topic and stance classification, embeddings, clustering, sentiment, brand safety, and related tasks across billions of news and social records
Multi-modal enrichment for image and video signals from social platforms, complementing our text-heavy core
Ad optimization systems built from the ground up, including bid optimization, budget allocation, creative selection, audience targeting, or related problems, grounded in historical performance data and well-reasoned heuristics
Experimentation design and execution: framing the question, choosing the right test, instrumenting it, and producing results the business can act on
Production ML infrastructure on GCP: training, evaluation, deployment, monitoring, and the glue that keeps models reliable as data shifts
Technical leadership for a small ML team, including code review, mentorship, prioritization, and raising the bar on rigor without slowing delivery
Cross-functional partnership with Data Engineering on pipeline integration, and with Account Management and Performance Managers to translate business problems into model problems
Core Competencies:
ML Breadth & Depth
Strong foundation across classical ML, neural networks, and Transformers, reaching for the right tool rather than the trendiest one
Comfortable with both supervised and unsupervised paradigms: classification, regression, clustering, dimensionality reduction, representation learning
Practical fluency with NLP and at least working familiarity with computer vision for image and video enrichment
Understanding of when a simple model beats a complex one, and the discipline to ship the simple one
Experimentation & Research Rigor
Track record of structuring and running experiments end-to-end: hypothesis, design, instrumentation, analysis, decision
Comfortable with ad hoc statistical testing, picking the right test for the task, reasoning about power, controlling for confounds
Knows the difference between a model that benchmarks well offline and one that holds up in production
Research mindset paired with a shipping mindset: rigorous, but allergic to research-for-its-own-sake
Optimization
Experience building optimization systems, whether mathematical optimization, heuristics, or learned policies, applied to a real-world domain
Comfortable reasoning about objective functions, constraints, and tradeoffs in messy business contexts
Advertising or adtech optimization experience is a strong plus
Production ML Engineering
Strong Python and the standard ML stack: scikit-learn, PyTorch, TensorFlow, HuggingFace, NumPy, pandas
FastAPI and async/await patterns for serving models and building ML-facing services
Experience working with data at scale, including the practical realities of billions of records: partitioning, sampling, distributed processing, cost management
GCP for training, serving, and infrastructure, such as Vertex AI, Cloud Run, GCS, or equivalent
PostgreSQL and Snowflake for working with large-scale data
Docker and CI/CD pipelines for reproducible, deployable ML workloads
Comfortable with the realities of production ML: data drift, retraining cadence, monitoring, cost management
Leadership & Collaboration
Experience leading or mentoring engineers, even informally, through code review, technical direction, and raising the bar on quality
Strong collaboration habits with Data Engineering, and the ability to translate fluently between technical and business audiences
Can sit with an Account Manager or Performance Manager, understand what they actually need, and turn it into a tractable modeling problem
Software Engineering Fundamentals
Clean code habits, sensible architecture, strong typing discipline
Test-driven mindset for ML code: covering data assumptions, edge cases, and regression paths, not just happy paths
Comfortable with modern dev practices: Git, code review, CI/CD
Advertising, adtech, or media industry experience
Familiarity with LLMs and modern AI tooling, useful context for the broader engineering org but not the focus of this role
Causal inference or uplift modeling background
Experience with recommendation systems or ranking
5+ years of ML experience, ideally with a foundation built before the LLM era
