About the role
ByLabs is hiring a Principal Recommendation System/Platform Engineer in Seattle to lead upgrading our core architecture and ML platform. You will drive transformation from rule-based personalization to an industrial-scale, real-time system serving millions of users.
You will collaborate across algorithm, growth, and data science teams to deliver high-throughput, low-latency services, training pipelines, and production-ready deployment with robust observability and disaster recovery.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
