Lead Applied Scientist - AI Search & Brand Intelligence
Descrizione dell'offerta
SE Ranking , an all-in-one SEO and digital marketing platform, is looking for a Lead Applied Scientist to reverse-engineer how AI search and generative platforms (ChatGPT, Gemini, Perplexity, AI Overviews) recommend and describe brands - and to build the measurement layer that proves what AI visibility is actually worth to a business. This is a founding-level role for a new discipline: AI Search Optimization and Brand Intelligence for Generative AI. This is not classic SEO, and it is not classic data science. You will be the technical owner of the research agenda - from hypothesis to experiment to insight to shipped product capability - and you will work alongside a small team (one ML Engineer today, a second one you will help hire), while staying deeply hands-on yourself. Why this role is different You get proprietary data most researchers can only dream about: SE Ranking 's SERP, backlink, content, audit, GA and GSC datasets, plus Planable's social media data - combined with systematically sampled AI-generated responses Your output is not only product features. It's the GEO best practice the industry will end up using - with the opportunity to represent that work at conferences and in company research, if that's something you'd enjoy The discipline is barely a few years old. Nobody is "the expert" yet - the first rigorous answers will come from someone with your access to data How the role splits This is primarily a hands-on technical role with some team leadership on top - you'll stay deeply hands-on in research and modelling, while also directing a small team's day-to-day work: setting technical direction, running 1:1s, unblocking people, and contributing to hiring decisions: ~45% hands-on research and modelling - you design and run experiments yourself ~45% technical and project leadership - hypothesis prioritisation, decomposition, methodology review ~10% people management - directing a small team's day-to-day (1-2 people): setting technical direction, running 1:1s, unblocking people What you'll do - first 90 days Partner with our SEO/GEO specialists and selected engineers to set up a repeatable experiment pipeline: hypothesis → data scope → design → run → insight → decision Run the first 3-4 experiments and, with Product, define candidate features that would give our customers a real AI-visibility practice Design sampling methods to systematically collect and analyse AI responses across topics, intents and regions - with explicit handling of variance, bias and representativeness Establish an evaluation framework for LLM outputs, prompts and model behaviour, so results are comparable over time What you'll do - ongoing Apply LLMs via batch API (including open-weight models) as feature extractors and judges: entity/sentiment/positioning extraction, prompt evaluation on holdout sets, cost-aware batch inference, agentic/tool-using pipelines Own the team's model evaluation & validation standards: leakage detection, temporal/out-of-time validation, and metric definitions tied to business outcomes Develop predictive and ranking models - gradient boosting (LightGBM/CatBoost), learning-to-rank (NDCG, precision@K) - for brand visibility, probability of mention in AI answers, and traffic/impressions in AI search and SEO Build classification, clustering and representation-learning models (embeddings, approximate nearest neighbours) that map how AI systems perceive and position brands Work directly in ClickHouse (or a similar columnar OLAP) on SERP, backlink, content, audit, GA and GSC data at hundreds-of-millions-of-rows scale, on infrastructure shared with the product Source hypotheses from across the company and the market, generate your own from patterns in data, and maintain a prioritised backlog with a clear execution cycle Mentor the ML Engineer(s) you work with: set technical direction, review methodology, delegate meaningfully, and participate in hiring Turn findings into product features, published research, conference talks and our own GEO best practice - working with Product, Engineering, Marketing and Leadership What you'll bring 5-6+ years in Data Science or Applied Science, with a track record of taking ambiguous research problems from hypothesis to a shipped decision Deep, hands-on expertise in ranking & information retrieval (learning to rank, NDCG/precision@K, LambdaRank/LambdaMART) - the core lens for how brands get surfaced by generative AI systems Strong, current GenAI/LLM expertise: using LLMs as an analysis tool - prompting and evaluating both commercial APIs and open-weight models (e.g. Llama, Mistral, Qwen - models we can run on our own infrastructure), LLM-as-judge or agent-evaluation experience, and an understanding of how sampling, context and model behaviour affect what a model "says" about a brand Rigorous model evaluation and validation: leakage detection, temporal/out-of-time validation, and choosing metrics tied to the business outcome Comfortable directing a small team's day-to-day (1-2 people): setting technical direction, running 1:1s, unblocking people - this doesn't require management brilliance, just the willingness and basic ability to do it well Solid English (B2+) - able to explain a complex result to a marketer and a sceptical engineer in the same meeting Nice to have Gradient boosting (LightGBM/CatBoost) for tabular modelling - we already have models built on this and need someone who can keep improving them Embeddings & representation learning (sentence-transformers, faiss) for semantic features and clustering Comfortable analysing large-scale data directly (e.g. ClickHouse) without depending on a dedicated engineer Genuine interest in the broader SEO/search domain - we don't expect domain expertise on day one, just curiosity and speed Familiarity with AI-search measurement concepts (AI Visibility, Share of Prompt, Share of Model) MLflow (or similar experiment tracking) experience Publications or talks (SIGIR, ECIR, KDD, ACL, EMNLP - or brightonSEO a
