Machine Learning Engineer - Distributed ML Systems Job at Pluralis Research in S

Overview

Pluralis Research carries out foundational research on Protocol Learning: multi-participant training of foundation models where no single participant has, or can ever obtain, a full copy of the model. The purpose of Protocol Learning is to facilitate the creation of community-trained and community-owned frontier models with self-sustaining economics.

We’re looking for Senior/Staff engineers with 5+ years of experience in distributed systems and ML large‑scale training. You’ll be implementing a novel substrate for training distributed ML models that work under consumer grade internet connection.

Responsibilities

Distributed Training Architecture & Optimization

• Design and implement large‑scale distributed training systems optimized for heterogeneous hardware operating under low‑bandwidth, high‑latency conditions.




• Develop and optimize model‑parallel training strategies (data, tensor, pipeline parallelism) with custom sharding techniques that minimize communication overhead.




• Optimize GPU utilization, memory efficiency, and compute performance across distributed nodes.




• Implement robust checkpointing, state synchronization, and recovery mechanisms for long‑running, fault‑prone training jobs.




• Build monitoring and metrics systems to track training progress, model quality, and system bottlenecks.

Decentralized Networking & Resilience

• Architect resilient training systems where nodes can fail, networks can partition, and participants can dynamically join or leave.




• Design and optimize peer‑to‑peer topologies for decentralized coordination across non‑co‑located nodes.




• Implement NAT traversal, peer discovery, dynamic routing, and connection lifecycle management.




• Profile and optimize communication patterns to reduce latency and bandwidth overhead in multi‑participant environments.

What You’ll Bring

• Strong experience building and operating distributed systems in production.




• Hands‑on expertise with distributed training frameworks (FSDP, DeepSpeed, Megatron, or similar).




• Deep understanding of model parallelism (data, tensor, pipeline parallelism).




• Expert‑level Python with production experience (concurrency, error handling, retry logic, clean architecture).




• Strong networking fundamentals: P2P systems, gRPC, routing, NAT traversal, distributed coordination.




• Experience optimizing GPU workloads, memory management, and large‑scale compute efficiency.

What We Offer

• Equity‑heavy compensation with meaningful ownership in a mission‑driven company




• Competitive base salary for senior engineering roles in Australia




• Visa sponsorship available for exceptional candidates




• Remote‑first with optional access to our Melbourne hub




• World‑class team — team mates were previously at Google, Amazon, Microsoft, and leading startups

Backed by Union Square Ventures and other tier‑1 investors, we’re a world‑class, deeply technical team of ML researchers and engineers. Pluralis is unapologetically ideological. We view the world as a better place if we are able to implement what we are attempting, and Protocol Learning as the only plausible approach to preventing a handful of massive corporations monopolising model development, access and release, and achieving massive economic capture. If this resonates, please apply.
