Despite being dismissed as infeasible, we have made significant advances on this problem, most recently Agora, a permissionless run that pretrained an 8B model from scratch on consumer GPUs spread over the internet, with no single participant ever holding the full weights (tech report https://arxiv.org/abs/2607.13332). While many of the core research problems have been solved, Protocol Learning unlocks a series of new challenges. For the mission in full, read A Third Path: Protocol Learning https://pluralis.ai/blog/a-third-path-protocol-learning/. Our inference pipeline generates the rollouts for reinforcement learning (RL) training today, and it'll serve our models once they're trained. It also runs in a permissionless, trustless setting, which makes the usual serving problem much harder. The hardware is Macs and consumer GPUs owned by strangers, the network is the public internet, nodes join and leave mid-run, and the weights change under the server as training moves. Your primary role is to build the systems that keep this pipeline fast and reliable under these conditions. ## KEY RESPONSIBILITIES - Own the inference stack: You build and own it end-to-end. Pipeline-parallel execution, placement and routing, the transport, the serving engine, and failure handling. You set the direction, and you make things happen. - Invent the algorithms: Making inference fast on consumer hardware over the public internet takes methods that don't exist yet. You design them, validate them, and put them in production. - Serve training and users: You keep the rollout pipeline fast and reliable for RL training now, and turn it into the serving layer for our models once they're trained. ## WHAT WE'RE LOOKING FOR - Shipped serving systems: You've shipped serving-engine internals or built a large-scale inference system yourself, and you can do this work hands-on today. - Research ability: Publications (papers and blogposts) in distributed inference or a nearby field, such as LLM serving systems, pipeline parallelism over slow networks, or decentralized training, are a strong signal. So is unpublished work you can walk us through. - Low-bandwidth networking: Experience with systems that run in low-bandwidth, high-latency settings like the public internet is a strong signal. - Mission alignment: You believe Protocol Learning is the viable third path for collective, trustless, and sovereign AI. ## NICE TO HAVE - Familiarity with RL post-training. - Exposure to Apple silicon or MLX. - Experience with P2P networking and NAT traversal. - 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 https://www.usv.com/ 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. ## About Pluralis Research ## Company Overview - **One-liner**: Pluralis Research is developing protocol learning to enable decentralized, collectively-owned and collaboratively-trained frontier AI models that are unextractable and operate over open, permissionless networks. - **Entity Type**: Private (Seed stage) - **Headquarters**: San Francisco, California, United States - **Founded**: 2024 - **Founders**: Alexander Long (Founder and CEO); Founding Scientists include Ajanthan Thalaiyasingam, Gil Avraham, and Sameera Ramasinghe. ## Core Business - **Primary Industry**: Foundational AI Research (Decentralized AI / Protocol Learning) - **Target Customers**: B2B (research institutions, compute providers, open-source community contributors); B2C indirectly (future users of collectively owned models) - **Mission/Purpose**: To create a third path for AI development beyond closed-source models and open-weight models—a self-sustaining, collectively owned ecosystem where models are trained and governed by a community, not a single corporation. ## Products & Services - **Protocol Learning (Core Protocol)**: A novel training paradigm where large AI models are split across geographically separated devices connected only by standard internet links. - **Type**: Research Protocol / Decentralized Infrastructure - **Key Innovation**: Models exist only within the protocol, not on any single device. They are trainable and usable but **unextractable**, preventing any single entity from capturing the model weights. - **Node0**: A collaborative event powered by Protocol Learning, enabling decentralized AI training runs. - **Type**: Open-source tool / Event Framework - **Agora**: A collaborative training library for multi-participant model training. - **Type**: Open-source Library (GitHub) - **AsyncPP & AsyncMesh**: Communication-efficient pipeline and mesh parallelism techniques for scaling decentralized models over low-bandwidth networks (achieving >95% compression and matching centralized wall-clock convergence). - **Type**: Open-source Algorithms (GitHub) ## Market Standing - **Valuation**: Not publicly disclosed - **Total Funding**: $8.6 million - **Non-Equity Assistance** (Nov 2025): $1.0M led by Amazon Web Services - **Pre-Seed Round** (Jan 2025): Led by CoinFund - **Seed Round** (Mar 2025): $7.6M co-led by Union Square Ventures and CoinFund, with participation from Topology, Variant, Eden Block, and Bodhi Ventures. Angel investors include Balaji Srinivasan and Clem Delangue (co-founder of Hugging Face). - **Notable Investors/Partners**: Union Square Ventures, CoinFund, Amazon Web Services, Balaji Srinivasan, Clem Delangue (Hugging Face) - **Growth Signals**: - Headcount grew **+100% YoY** (from ~7 to 17 employees). - Published multiple papers at **NeurIPS 2025** on decentralized training (e.g., Subspace Networks, Mixtures of Subspaces). - 10 active job openings across Research, ML Engineering, and Distributed Systems. - Team has deep FAANG/Anthropic pedigree (Google, Amazon, Oracle, Atlassian alumni). ## Competitive Advantages - **Technical Moat (Unextractable Models)**: Their core IP ensures model weights are never materialized on any participant's device, preventing theft or centralization even during training. - **Economic Moat (Self-Sustaining Economics)**: The protocol allows value to flow programmatically to contributors, solving the financial sustainability problem that plagues purely open-weight models. - **Published Research**: Validated by acceptance at NeurIPS 2025, demonstrating academic credibility and technical rigor. - **Talent Density**: The team comprises PhD researchers who previously worked together at top AI labs (Anthropic, Google, Amazon), with deep expertise in distributed systems and ML. ## Strategic Focus - **Hiring in All Areas**: Currently recruiting across Research, ML Training Platforms, and Distributed ML Systems to accelerate protocol scaling. - **Scaling Decentralized Networks**: Aiming to prove that model-parallel training over low-bandwidth (30Mbps) internet is feasible for billion-parameter models. - **Building Community**: Opening participation in training runs to external contributors, moving toward a truly permissionless network. ## Why Work Here - **Culture of Radical Openness**: The mission is to democratize AI ownership. Work here is published openly, and researchers contribute to a public good. - **High Impact, Small Team**: With only 17 people, every hire has an outsized influence on shaping the protocol and company direction. - **Research First**: The team is PhD-heavy and publishes at top-tier conferences (NeurIPS). The environment is scholarly and technically deep. - **Remote-Flexible (Hybrid)**: Presence in San Francisco (US) and Australia (largest cohort of 12 employees). The job postings do not mandate 5 days in-office; distributed collaboration is core to the product itself. - **Top-Tier Investor Backing**: Backed by USV and CoinFund, providing strong financial runway and network effects in both the AI and crypto/Web3 ecosystems. - **Founding Team Pedigree**: Work alongside former researchers from Anthropic, Google, and Amazon, creating a steep learning curve for ML engineers and scientists. ## Sources 1.
