About Clarity

We're pioneering Agentic AI - systems that don't just respond, but reason, act, and adapt autonomously in complex workflows. This is about crafting AI Agent Experiences - designing agents that collaborate seamlessly with humans, learn from context, and make every customer interaction faster, smarter, and more empathetic.

You'll own the technical vision and turn requirements into a live, reliable product used by brands like Grubhub, , 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

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.

What makes you a great fit

  • 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
