Applied Researcher - Continual Learning

Full-time

About the Job

Requirements

  • Relevant experience in continual or online learning, reinforcement learning, meta-learning, memory systems, post-training data loops, adaptive production machine learning, or evaluation under changing distributions.
  • Hands-on experience building and debugging model-training, post-training, agent, evaluation, or closely adjacent experimental loops.
  • Strong experimental judgment, including meaningful baselines, careful trace inspection, clear failure attribution, and willingness to change direction when evidence changes.
  • Strong Python skills and ability to build artifacts that other researchers and engineers can run, inspect, and extend.
  • Comfort owning ambiguous problems and keeping partners and teammates current while resolving them.

Responsibilities

  • Build continual learning systems that turn agent trajectories, corrections, and failures into new tasks and model updates.
  • Compare streaming reinforcement learning, batched post-training, and distillation, and determine which improvements belong in model weights or persistent memory, skills, prompts, and subagent state.
  • Track skill acquisition, transfer, forgetting, and loss of plasticity over long sequences of tasks.
  • Turn workflows into tasks, environments, evaluations, and reward signals; run post-training experiments against real baselines; deploy successful results; and determine whether gains came from the model, data, harness, inference, or infrastructure.
  • Work directly with customers, users, or research partners while maintaining a substantive research agenda.
  • Control update cadence, policy lag, task drift, and exploration, and evaluate checkpoints on earlier skills, unseen tasks, and general capabilities.
  • Build task-generation and training pipelines with reproducible data and harness versions so regressions can be traced to a specific change and rolled back.
  • Work directly with external collaborators whose deployments drive the research.
  • Select high-value production traces and interventions, convert them into training signal, and establish regression gates before a change reaches deployment.
  • Determine which adaptation belongs in model weights, harness state, memory, tools, or data, and measure tradeoffs across a sequence of tasks.
  • Build evaluations that distinguish retained learning and transfer from memorization, context accumulation, or measurement drift.
  • Own methods for selective consolidation, replay, adaptation, memory, and online or offline reinforcement learning.
  • Own evaluations for retention, transfer, regression, and rollback as tasks and distributions change.
  • Own promotion gates and human oversight for agents that continue to change in production.
  • Conduct field experiments, build benchmarks, and produce open research that makes continual improvement measurable and transferable.

Desired Qualifications

  • Publications, open-source systems, benchmarks, and shipped products are valued as evidence of exceptional work.

About the Company

Prime Intellect

Open frontier-model stack for enterprise RL

Prime Intellect provides an open, end-to-end superintelligence stack for enterprises to train and continually improve their own AI agents. The platform includes scalable compute, large-scale reinforcement learning, environments, sandboxes, evaluations, and deployment tools, and it ships open frontier models to customers. It covers the full lifecycle from training to deployment plus post-training support, enabling agentic training at scale. Its differentiator is the open, end-to-end stack used across thousands of customers with strong backing from top investors, and its goal is to help organizations build and iteratively improve their AI agents using open frontier models.
