Job description

Clarity is redefining customer experience with AI. Our mission is to empower businesses to deliver faster, smarter, and more human service interactions. By combining cutting-edge AI with intuitive design, we enable customer service teams to operate more efficiently while providing customers with seamless, personalized experiences.

We are trusted by industry leaders like OpenAI, GrubHub, STC and Tabby who rely on us to deliver real impact. Our investors include Prosus Ventures, STV AI Fund (backed by Google) and angels from Open AI and Google. With a 25% month-on-month growth rate and over 300% net revenue retention, this is a unique opportunity to join a hyper-growth AI company and redefine an industry. What you'll actually do 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.

Requirements

  • 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). xhkmmrq
  • Prior experience in contact center/CX analytics or novelty/anomaly systems.
  • Founder or founding engineer experience
