AI Researcher - Robot Learning
Confirmed on the employer's own hiring board on Oct 18, 2026. First seen by Alion on Jun 17, 2026.
About 1X
We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it's not.
To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you're inspired by this, you'll thrive here. We've been at this since 2014 and we're at the point where the hard problems are behind us and the hard work is in front of us.
NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We're not demoing it - we're shipping it. We're excited to meet you, if this excites you.
If you've spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We're scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.
About the Team
The Motion team enables NEO to move through and interact with the world. We build the perception NEO needs to understand its surroundings and locomote through any environment, and the control that lets it use its whole body to accomplish real tasks - crawling, bracing, climbing, lifting with more than just its arms. Because NEO operates around people, safe and compliant motion is a design constraint on everything we ship, not a feature layered on top.
Your Charter
Own the full pipeline from RL algorithm development through production deployment: training NEO on manipulation and locomotion tasks in simulation, closing the sim-to-real gap, and shipping policies that work reliably in real-world environments. This is critical-path work: the range of tasks NEO can perform safely and reliably is a direct function of the quality of RL policies your team ships. You will collaborate closely with the hardware and world model teams, and measure your impact by what NEO can do in the field.
Key Outcomes
Train and deploy RL policies for manipulation and locomotion tasks that perform reliably in real-world home environments measured by field task success rates, not just simulation benchmarks
Advance sim-to-real transfer techniques that measurably narrow the gap between simulation training performance and real-world policy behavior, enabling faster iteration cycles
Build training and evaluation infrastructure that lets the team iterate on policies faster with standardized benchmarks, automated regression detection, and clear connections between training metrics and field performance
Partner with hardware, controls, data, and QA teams to ship RL-trained skills to production customer sites, owning the handoff from research to deployment
Key Competencies
Sim-to-real practitioner closing the sim-to-real gap on physical systems; understands domain randomization, reward shaping, and the engineering required to make simulated policies transfer reliably to real hardware
RL algorithms depth with strong foundation in RL algorithms (PPO, SAC, TD-MPC, or similar); can choose the right approach for the task and modify or extend it when standard methods fall short
Full-stack ownership owning data engineering, model architecture, and deployment; treats a promising training curve as the beginning of the job, not the end
Effective cross-functional partner working closely with hardware, controls, QA, and data teams to translate RL research into deployed robot skills, and communicates technical constraints clearly across disciplines
Minimum Requirements
Strong Python and/or C++ with experience in large codebases and build tools (Bazel or equivalent)
Proficiency with PyTorch for RL policy training and experimentation
Hands-on experience with simulation platforms (Isaac Sim, MuJoCo, or equivalent) for policy training at scale
Demonstrated experience training RL policies for manipulation or locomotion tasks, including addressing the sim-to-real gap on physical hardware
Preferred Skills
Experience with model-based RL or world-model-guided policy learning that leverages predictive models to improve sample efficiency
Familiarity with imitation learning or learning from demonstration (behavior cloning, GAIL, IQL) as a complement or bootstrap to RL
Experience deploying RL-trained policies to physical robots in production environments, including monitoring, failure analysis, and iterative improvement
Background in legged locomotion, dexterous manipulation, or contact-rich control for physical systems
Compensation
Salary Range: $200,000 - $300,000 + Equity
Benefits
Comprehensive medical, dental, and vision coverage
Generous paid time off, company holidays, and parental leave
401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
Commuter benefits (transit and parking)
Short-term and long-term disability, and life insurance
Employee Assistance Program (EAP) for mental health, financial, and personal support
Onsite snacks and catered lunches
