Applied Machine Learning Engineer

Nooks

The Nooks AI Sales Assistant Platform automates busywork in dialing, coaching, and prospecting to 3x pipeline generation.

Nooks is a platform transforming sales reps from manual laborers to scientists. With today's technology, sales reps shouldn't need to manually write hundreds of emails, research hundreds of websites / LinkedIn, and make hundreds of calls. They should instead focus on the parts of their job that actually require people - talking to customers, being creative, and problem-solving. With a combination of AI tools, automation, and real-time collaboration, Nooks can do the rest.

The Role

Note : Exact job title will be commensurate with experience.

We have an ambitious product vision in a nascent area - AI-powered real-time collaboration - so there are a ton of interesting technical challenges on our roadmap. This is a role focused on implementing ML features into Nooks. Our ideal candidate will have prior experience working in an industry where ML is a core part of the offering.

Responsibilities will include training production models to improve their accuracy for specific sales use cases. You will align our technical strategy with performance, cost, and feasibility considerations.

Examples of Engineering Problems You May Touch

These are just examples; this list is non-exhaustive, and you definitely don't need experience in all of these areas. But hopefully, you find some of them exciting!

Real-time Audio AI & Precision / Recall / Latency Tradeoffs (Algorithms & Models)

We use audio data, transcription, silence detection, and several other signals to detect whether a live phone call is a voicemail, a human, or a dial tree. Here, latency is a third factor added to the standard precision / recall tradeoff because it's important we can detect humans quickly. Our approach involves LLM embeddings, few-shot learning, data labeling, and continuous monitoring of model performance in production.

Smart Call Funnels & Playbooks (Data Wrangling, Backend Engineering, GPT-3, UX)

At what point in the conversation do my reps get stuck? What are the toughest questions that we need to address? Can I "program" a playbook so that Nooks will help my team standardize toward best practices? We're using GPT-3 and other LLMs to turn companies' mostly unstructured call data into actionable strategies & feedback loops.

Conversation Embeddings & Markov Models (ML Modeling)

What does the anatomy of a call look like? If I say XYZ, what are the different ways the prospect might answer and the probabilities of each? Conditioned on the first half of the call, what do I say next to maximize the likelihood that I book a demo at the end of the call? Can we use LLMs to generate embeddings of conversations that we can use to cluster similar conversation patterns and predict where the conversation is headed?

Requirements

Bachelor's or Master's degree in Computer Science, Machine Learning, Data Science, or a related field.

3 years of industry experience, including 2 years training and deploying ML models in production.

Full stack ML Engineering proficiency : experience with general-purpose programming languages such as Python / Javascript, and libraries like TensorFlow, PyTorch, Keras, scikit-learn, etc.

Expertise in areas like NLP, Deep Learning, Anomaly Detection, Transformers, and Large Language Models.

Nice to Haves

Background in an analytical field like heuristics, data science, and / or statistics.

Prior experience working in both startup and research environments.
