Senior Application Engineer - Customer Experience

Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond. We operate at the cutting edge of Applied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better. JOB SUMMARY Apptronik's most important audiences — the executives, customers, investors, and partners who will define how the world sees Apollo — encounter our technology through live demonstrations. This role is responsible for making those moments exceptional. As Senior Application Engineer, Customer Experience , you will own the full lifecycle of Apollo demonstrations at our California office and at events worldwide. You will design, build, and operate the robot behaviors and workcell environments that bring Apollo to life for VIP visitors — applying the same engineering discipline, rigor, and process we use for every customer field deployment. Operating as the senior technical presence at our California satellite office, you will work with significant autonomy, represent Apptronik's engineering capability to our most critical audiences, and serve as a direct feedback channel between what customers experience and what our product teams build. This is a high-visibility, high-impact engineering role at the intersection of robotics, customer engagement, and product storytelling. This role is part of the Applications Engineering team and operates under the same processes, standards, and expectations as every other Application Engineer. The California office is a flagship environment where Apptronik's capabilities are on display to the world's most important audiences, and this engineer plays a central role in shaping those experiences. ESSENTIAL DUTIES AND RESPONSIBILITIES or KEY ACCOUNTABILITIES: Requirements & Strategy Stakeholder alignment — Partner with Sales, Marketing, and Customer Success leadership to define objectives, success criteria, and technical scope for each high-priority visit; capture the agreed storyline and constraints in a concise brief that aligns all internal stakeholders before execution begins. Technical scoping authority — Serve as the definitive technical voice on Apollo's demonstrable capabilities — providing honest, confident assessments of what can be shown credibly and reliably to any given audience, and shaping stakeholder expectations accordingly. Audience-driven design — Translate visit objectives into scenario designs that reflect real customer problems and workflows, ensuring every demonstration is grounded in the customer's world, not just the robot's capabilities. Design & Architecture Solution architecture — Design demonstration scenarios with the same structured approach used in customer field deployments: clear requirements, defined success criteria, risk assessment, and a documented architecture that can be handed off and reproduced. Fallback and risk design — Define comprehensive fallback architectures and failure-mode mitigation strategies that protect demonstration integrity under live conditions — anticipating failure paths before they occur and building recovery into the run-of-show by design. Simulation-driven development — Build and maintain demonstration-specific simulation environments using tools such as NVIDIA Isaac Sim, Gazebo, or MuJoCo to validate and optimize robot behaviors before live deployment, reducing integration risk and rehearsal time. Build & Integration Application development — Develop, configure, and tune the demo applications and robot behaviors required for each scenario, reusing producti…
