Member of Technical Staff Applied ML RecSys at Liquid AI
Краткое
Liquid AI is hiring: Member of Technical Staff Applied ML RecSys.
Location: Remote
Compensation: Competitive base salary with equity in a unicorn-stage company
Spun out of MIT CSAIL, we build general-purpose AI systems that run efficiently across deployment targets, from data center accelerators to on-device hardware, ensuring low latency, minimal memory usage, privacy, and reliability. We partner with enterprises across consumer electronics, automotive, life sciences, and financial services. We are scaling rapidly and need exceptional people to help us get there.
What you'll do:
• This is a rare chance to apply frontier sequential recommendation architectures to real enterprise problems at scale. You will own applied ML work end-to-end for recommendation system workloads, adapting Liquid Foundation Models for customers who need personalization and ranking capabilities that run efficiently under production constraints.
• Unlike most recommendation roles that are siloed into a single product surface, this role gives you full ownership over how large-scale recommendation models are adapted, evaluated, and deployed for enterprise customers. Between engagements, you will build reusable applied tooling and workflows that accelerate future delivery.
• If you care about data quality at scale, user behavior modeling, and making recommendation systems actually work in enterprise production environments, this is the role.
• What We’re Looking For
• Takes ownership: Owns customer recommendation system engagements end-to-end, from requirements through delivery and evaluation.
• Thinks at scale: Can reason about user interaction data, sequential modeling, feature engineering, and evaluation across large-scale production systems.
• Is pragmatic: Optimizes for measurable customer outcomes (engagement, conversion, revenue lift) over theoretical novelty.
• Communicates clearly: Can translate between customer business metrics and internal technical decisions, and push back when needed.
Requirements:
• Hands-on experience building or fine-tuning recommendation models at scale (not just off-the-shelf collaborative filtering)
• Experience with sequential recommendation architectures, user behavior modeling, or large-scale ranking systems
• Strong intuition for data quality and evaluation design in recommendation contexts (offline metrics, A/B testing, business metric alignment)
• Experience with large-scale data pipelines for user interaction data and feature engineering
• Proficiency in Python and PyTorch with autonomous coding and debugging ability
Nice to have:
• Experience with transformer-based recommendation architectures (HSTU, SASRec, BERT4Rec, or similar)
• Experience delivering recommendation systems to external customers with measurable business outcomes
• Familiarity with serving recommendation models under latency and throughput constraints
• What Success Looks Like (Year One)
• Independently owns and delivers enterprise recommendation system engagements with minimal oversight
Benefits & perks:
• Real ML work: You will build and adapt large-scale recommendation models for enterprise customers, working with frontier architectures like HSTU under real production constraints.
• Health: We pay 100% of medical, dental, and vision premiums for employees and dependents
• Financial: 401(k) matching up to 4% of base pay
• Time Off: Unlimited PTO plus company-wide Refill Days throughout the year
• Please mention the word LYRICAL and tag ROjox when applying to show you read the job post completely (#ROjox). This is a beta feature to avoid spam applicants. Companies can search these words to find applicants that read this and see they're human.
Skills: design, system, python, training, technical, financial, digital nomad

The Opportunity
This is a rare chance to apply frontier sequential recommendation architectures to real enterprise problems at scale. You will own applied ML work end-to-end for recommendation system workloads, adapting Liquid Foundation Models for customers who need personalization and ranking capabilities that run efficiently under production constraints.
Unlike most recommendation roles that are siloed into a single product surface, this role gives you full ownership over how large-scale recommendation models are adapted, evaluated, and deployed for enterprise customers.

What We’re Looking For
We need someone who:
Takes ownership: Owns customer recommendation system engagements end-to-end, from requirements through delivery and evaluation.
Thinks at scale: Can reason about user interaction data, sequential modeling, feature engineering, and evaluation across large-scale production systems.
Is pragmatic: Optimizes for measurable customer outcomes (engagement, conversion, revenue lift) over theoretical novelty.
Communicates clearly: Can translate between customer business metrics and internal technical decisions, and push back when needed.
The Work
Act as the technical owner for enterprise customer engagements involving recommendation and ranking workloads
Translate customer requirements into concrete specifications for recommendation models
Design and execute data pipelines for user interaction data, feature engineering, and training data curation at scale
Fine-tune and adapt large-scale sequential recommendation models (e.g., HSTU-style architectures) for customer-specific use cases
Design task-specific evaluations for recommendation model performance (ranking quality, latency, throughput) and interpret results
Build reusable applied tooling and workflows that accelerate future customer engagements
Desired Experience
Must-have:
Hands-on experience building or fine-tuning recommendation models at scale (not just off-the-shelf collaborative filtering)
Experience with sequential recommendation architectures, user behavior modeling, or large-scale ranking systems
Strong intuition for data quality and evaluation design in recommendation contexts (offline metrics, A/B testing, business metric alignment)

Familiarity with serving recommendation models under latency and throughput constraints
What Success Looks Like (Year One)
Independently owns and delivers enterprise recommendation system engagements with minimal oversight
Is trusted by customers as the technical owner, demonstrating strong judgment on the tradeoffs between model quality, latency, and business impact
Has built reusable applied workflows or tooling that accelerate future customer engagements
What We Offer
Real ML work: You will build and adapt large-scale recommendation models for enterprise customers, working with frontier architectures like HSTU under real production constraints.
Compensation: Competitive base salary with equity in a unicorn-stage company
