About the job

Requirements
  • A PhD in machine learning, robotics, computer science, applied mathematics, or a related field, or an equivalent record of original research demonstrated by publications, research systems, or deployed capabilities that can be examined during the hiring process.
  • Have led a consequential technical direction in robot learning, reinforcement learning, imitation learning, or embodied foundation models and be able to show how decisions changed the resulting system or research program.
  • Strong Python and PyTorch or JAX skills, plus working C++ ability for model integration, profiling, and real-time inference.
  • Have trained an embodied model or policy using a versioned dataset and evaluated it on held-out tasks, environments, embodiments, tools, or agent configurations defined before model selection.
  • Have deployed a learned model on a physical robot, autonomous vehicle, or other closed-loop physical system, and be able to present measured performance, the validation design, and a failure that changed the research direction.
Responsibilities
  • Develop, pretrain, and adapt robot foundation models that acquire reusable physical capabilities from heterogeneous experience.
  • Set the research roadmap, technical standards, and experimental decision process for GRAM's robot-learning program.
  • Design representations, objectives, architectures, and adaptation methods that transfer across robot morphology, sensor configuration, task, environment, tool, and machine variation.
  • Build training curricula from heterogeneous physical and simulated experience, with strict dataset and checkpoint lineage.
  • Scale experiments in PyTorch or JAX while separating gains from model architecture, objective, data composition, compute, initialization, and evaluation leakage.
  • Define frozen evaluations and falsifiable capability claims for task transfer, environmental robustness, embodiment transfer, data efficiency, latency, and recovery.
  • Deploy selected models through C++ robotics runtimes, then use physical failures and offline-to-online discrepancies to determine the next research question.
  • Help recruit, evaluate, and mentor the researchers and engineers who extend the program.
Desired Qualifications
  • Experience with vision-language-action models, transformer or diffusion policies, offline reinforcement learning, imitation learning, or self-supervised representation learning.
  • Experience with technical agenda-setting, research hiring, mentoring, or establishing evaluation standards for an early research program.
  • Experience with distributed training, active data collection, sim-to-real transfer, closed-loop fleet learning, or large-scale evaluation systems.

About the company

Gramn provides cloud-based HR software under the Jobcan brand to streamline HR tasks. Its main product, Jobcan Attendance Management, tracks employee time across multiple clock-in methods (PC, phone, IC cards, biometric devices) with real-time data on a central dashboard, automates work-hour calculations and overtime, and sends alerts to avoid missed clock-ins. Jobcan Shift Management lets employees digitally submit shift preferences, after which the system generates optimized schedules based on requests and staffing needs. Additional modules include Leave Management and Payroll, which integrates attendance data to simplify payroll processing. Offered on a subscription basis, customers pick and combine the functions they need. The system is multi-language, supports integration with external payroll software, and targets a wide range of industries and company sizes.

Simplify's Take

What believers are saying

  • Jobcan launched ScanSnap integration on 2026-01-30, strengthening document workflow automation.
  • Jobcan won multiple IT Trend rankings in 2025 and 2026, boosting sales credibility.
  • Jobcan expanded through seminars and partner events in 2026, creating low-cost enterprise pipeline.

What critics are saying

  • MoneyForward and freee keep pressuring Jobcan on integrated ERP and finance workflows.
  • Jobcan still relies on CSV-based integrations with Tofu, exposing product depth gaps in 2026.
  • Any labor-law compliance failure in attendance data risks customer churn and reputational damage quickly.

What makes GRAM unique

  • Jobcan bundled nine back-office modules across attendance, payroll, and accounting in 2026.
  • Jobcan reached 300,000 cumulative customer companies by 2025-12, signaling strong domestic stickiness.
  • Jobcan co-developed HR AI initiatives with Japanese labor specialists on 2026-04-21.
