Data Science Tech Lead: GenAI

Location: London, hybrid About Anecdote

Anecdote we’re on a mission to make customer experience delightful for everyone involved  . Think a real‑time copilot that listens to live calls and chats, reads our customers’ knowledge bases, and drafts high‑quality replies for human agents - while also turning messy, multi‑channel feedback into trustworthy structured insights , anomaly detection , and novelty discovery .

As the Tech Lead, you’ll own the technical vision and turn requirements into a live, reliable product used by brands like Grubhub, Booking.com, Dropbox, Uber, Careem, and Fubo . You’ll collaborate directly with engineers, other tech leads, directors, and the CTO to evolve ambitious prototypes into a rock‑solid, scalable platform.

50% Build — design & ship

• Agentic AI for CX: Real‑time assistants that listen to calls/chats, retrieve from customer KBs, and draft responses with human‑in‑the‑loop controls.
• Structured extraction: Schema‑driven pipelines over unstructured text (and other modalities) using retrieval, tool‑use, and robust LLM prompting.
• Hybrid anomaly detection: Blend classical time‑series methods (e.g., decomposition, change‑point, forecasting) with LLM‑aware, contextful detectors for seasonality, spikes, step‑changes, and drift.
• Novelty discovery: Embedding‑based clustering and drift, topic surfacing, LLM summarization of emerging themes with deduplication and evidence links.
• Alerting & scoring: Severity/impact ranking, de‑noising, suppression/cool‑downs, routing, and feedback loops.

25% Architect & scale

• Own reliability, latency, and cost. Design online/offline eval harnesses, canaries, and SLAs; operate GPUs/accelerators where needed.
• Stand up and harden RAG pipelines (indexing, retrieval policies, grounding, guardrails) and agent frameworks.
• Take basic infra ownership on GCP (or AWS/Azure): networking, autoscaling, CI/CD, IaC, observability, and cost tuning.
• Participate in on‑call for your area and drive root‑cause analysis with crisp follow‑ups.

15% Collaborate

• Pair with back‑end & front‑end to wire extractors/detectors and agents into ticketing, voice, and analytics stacks (APIs, webhooks, real‑time streams).
• Partner with PMs/CX to evolve taxonomies, schemas, and guardrails; translate business problems into shipped ML features.

10% Align & showcase

• Gather requirements from CX and product leads, demo new capabilities to execs & customers, and document impact with precision/recall, alert quality, latency, and cost metrics.

• Startup hacker mindset: You self‑start from zero, respect no silos, and carry work from prototype to production. 🛠️
• AI‑native dev tools are your daily drivers: Cursor, v0, Claude Code (or similar).
• 7–10 years building production ML/back‑end systems; 2+ years leading while coding.
• Expert Python ; strong back‑end chops (e.g., FastAPI, gRPC, Postgres, pub/sub/streams).
• Agents & RAG: Fluency with at least one agent framework ( ADK preferred ). Proven track record shipping AI agents and building RAG pipelines.
• LLM + DS depth: Prompting/tooling, retrieval design, LLM evals; hands‑on with time‑series analysis (forecasting, change‑point, drift).
• Cloud & ops: Basic infra ownership on GCP (or AWS/Azure): networking, autoscaling, CI/CD, IaC, observability, and cost control.
• Communication: You explain results clearly, align stakeholders, and write crisp docs.

Bonus points

• DevOps wizardry; GPU/accelerator experience.
• Multimodal pipelines (text + voice + screenshots).
• Prior experience in contact center/CX analytics or novelty/anomaly systems.
• Founder or founding engineer experience
