Robotics Engineer

Arche Halo Dynamics is the Physical AI and Advanced Robotics venture of Arche. We're building sensor-integrated robotic systems for industrial environments where human access is unsafe — oil & gas, mining, civils, energy infrastructure.
We are in pilot phase in Buenos Aires. The hardware is a Unitree quadruped with LiDAR, depth camera, and external IMU. The software stack is ROS 2.
We're hiring the Robotics Systems Lead — the founding engineer who owns the integration architecture and the interfaces every subsequent hire builds against.
Backgrounds we want to hear from
Aerospace and satellite systems — INVAP, VENG, Satellogic, ARSAT, or comparable. Attitude control, sensor fusion, telemetry, real-time onboard software.Automotive embedded and ADAS — perception pipelines, CAN bus, sensor calibration, safety-critical software.Industrial automation and process control — PLCs, SCADA, instrumentation, real-time control loops in oil & gas, mining, power, or heavy industry.Drone and UAV autonomy — PX4, ArduPilot, MAVLink, autonomous flight stacks.Autonomous vehicle and mobile robotics research — CONICET, ITBA, FIUBA, UTN, or comparable, with shipped work beyond simulation.High-reliability embedded systems — telecom, medical devices, defense, scientific instrumentation. Real-time Linux, deterministic timing, hardware-software co-debugging.
What you'll own
Integration architecture for the Unitree platform: sensor pipeline, software stack, mission execution layer.Sensor integration and time-synchronized fusion across LiDAR, IMU, and depth camera.The vendor SDK boundary — version pinning, adapter design, deprecation strategy.Development workflow: Docker-based environments, on-robot deploy, reproducible builds, regression on recorded data.Technical coordination with the Perception/Navigation engineer and the Embedded/Controls engineer. You set the interfaces; they build against them.Direct technical reporting to the CTO.
Required
Real-time systems intuition: timing, latency, jitter, synchronization.Sensor fusion fundamentals: Kalman filters, complementary filters, or factor graphs in active working knowledge.Strong C++ and Python.Embedded Linux: board bring-up, driver debugging, peripheral integration.Systems judgment: when to abstract, when to inline, when to refactor, when to ship.Track record as the technical anchor of a small multidisciplinary team.Engineering discipline: version control, reproducible builds, written technical communication.Demonstrated capacity to close stack gaps on own initiative.
Preferred
ROS 2 production experience.Direct experience with a commercial robot SDK (Unitree, Boston Dynamics Spot, ANYbotics, ArduPilot, PX4).LiDAR-inertial SLAM working knowledge (FAST-LIO2, LIO-SAM, RTAB-Map, Cartographer).Deployment experience in harsh or safety-constrained environments.Open-source contributions in robotics, embedded, or autonomy stacks.Spanish and English.
LocationOn-site, Buenos Aires office. Daily hardware access is required.
