Key Responsibilities
- Own the threat model : You enumerate what a malicious or careless worker can do across pre-training, post-training, and inference — training disruption and denial-of-service, free-riding, model poisoning and backdoors, data extraction from gradients and activations, reputation and reward manipulation — and you keep that model current as the network grows.
- Design and calibrate the tests : You build statistical verification methods with stated error rates, tune them with rigorous benchmarks, and keep false positives and false negatives controlled across heterogeneous hardware, including different GPUs and Macs.
- Ship the verifier : You build and run the verification service in the inference path, and you live with its mistakes.
What We're Looking For
Verification systems, shipped or published : You've built a calibrated statistical decision system with stated error rates and lived with its mistakes. Publications in inference and training verification count; fraud detection, anti-cheat, and experimentation platforms count as much as papers do.
Statistical depth : Deep expertise in statistics and probability, with the ability to design experiments, calibrate decision thresholds, and defend the error rates you claim.
Technical background : You know the solution space for verifying untrusted compute, from statistical testing to re-execution, cryptographic proofs, and trusted hardware, and you can argue what fits a permissionless network and what doesn't.
Mission alignment : You believe Protocol Learning is the viable third path for collective, trustless, and sovereign AI.
Nice to Have
Familiarity with large scale Pre-training and RL post-training.
Familiarity with decentralized ML security and adversarial threat models, such as poisoning, Sybil, collusion, and replay.
Experience at proprietary, open-weight and open-source AI labs
Compensation & Benefits
- Equity-Heavy Package : We offer significant ownership for key technical contributors in addition to a high base salary.
- Remote-First Culture : Flexible work environment with team members distributed globally.
- Visa Sponsorship : Optional full visa sponsorship and relocation support to either Australia or the US.
- Open Problems : Training and serving frontier models on hardware you don't control, over networks you don't own, mostly has no published answers yet. You'll write some of the first ones.
FYI's
We work remotely across the world, with the main teams in Australia and North America. You'll need to be comfortable working across timezones.
Applicants must have professional-level English proficiency (written and spoken).
Recruiters: we aren't looking for agency support at this time. We'll reach out if we need help.
We are backed by Union Square Ventures and other tier-1 investors, and we are a world-class, deeply technical team of ML researchers. Pluralis is unapologetically ideological. We believe AI, and the world, end up on a better path if we succeed in implementing the protocol for intelligence. If this resonates, please apply.
