Senior Software Engineer

The Opportunity: Our client is building a high-volume, professional engagement platform for LinkedIn with a roadmap to 100,000 users. They are looking for a Technical Lead / Founding Engineer (Remote) to own the architecture.
The current market is full of fragile tools that get user accounts restricted. Our client is building the antidote: a robust, safety-first ecosystem that blends high-scale infrastructure with human-level stealth.
This is a systems-level engineering role, not a growth-hack experiment.
The Engineering Challenges You Will Solve:
Scale beyond the script: How do we transition from a simple automation script to a decentralized backend that coordinates 100,000+ daily actions without triggering LinkedIn's rate limits?
The Stealth Protocol: How do we engineer browser automation that is indistinguishable from human behavior (randomized delays, non-linear mouse paths, varied user agents)?
Algorithmic Fairness: How do we mathematically ensure equitable value...
