Bygg robotar för den långa promenaden.

About the role

As our senior robotics engineer, you'll own our robots' sensing and autonomy: from choosing the sensors that let a mobile robot see clearly in busy, glass-walled indoor spaces, to the navigation that moves calmly among people and stops exactly where a person takes over. You'll set the technical direction, take the robot from prototype to field tests on real routes, and help build the engineering team.

What you'll do

• Own the sensor suite end to end: requirements, selection, placement, integration, calibration and validation.
• Evaluate and select sensors: 2D/3D LiDAR (mechanical and solid-state), depth, stereo and ToF cameras, IMU, wheel encoders, ultrasonic, bumper and cliff sensors, and safety-rated sensors such as safety laser scanners.
• Make the trade-offs explicit: range, field of view, resolution, behaviour on glass, reflective floors and sunlight indoors, latency, compute load, power, cost, supply chain and certification.
• Design sensor placement and coverage on the robot body, including around any payload and for people close to the robot.
• Set up intrinsic and extrinsic calibration and time synchronisation, for example PTP or hardware triggering.
• Design the sensor-fusion architecture, its failure modes and the redundancy needed to operate safely around people.
• Benchmark candidate sensors and vendors on real routes, and define the perception and compute budget on NVIDIA Jetson.
• Lead navigation, mapping and localisation (ROS 2, Nav2) within one mapped zone: calm, predictable paths through dense crowds, and boundaries the robot never crosses.
• Take the robot from prototype to field deployment on pilot routes, with simulation, test tooling, logging and remote assistance.
• Set technical direction, review designs and code, and mentor future hires.

What we're looking for

• 3+ years building and shipping autonomous mobile robots, with field deployments.
• Deep, hands-on expertise in sensor selection, integration and fusion for mobile robots.
• Deep knowledge of ROS 2 and Nav2, and of SLAM and localisation on real robots.
• Strong C++ and Python on Linux.
• A track record of taking robots from prototype to field deployment.
• Technical leadership: you set the architecture, review others' work and mentor engineers.
• A safety-first mindset for robots that work around people.

Robot tech stack experience

Sensors & hardware

2D/3D LiDAR (mechanical and solid-state), depth, stereo and ToF cameras, IMU, wheel encoders, ultrasonic, bumper and cliff sensors, safety laser scanners

Calibration & time sync

Intrinsic and extrinsic calibration (for example Kalibr), PTP, hardware triggering

Middleware & control

ROS 2, Nav2, ros2_control

Mapping & localisation

SLAM (slam_toolbox, Cartographer), AMCL, EKF sensor fusion (robot_localization)

Perception

OpenCV, PyTorch, person detection and tracking

Planning

Path planning and obstacle avoidance in dynamic crowds, behaviour trees

Edge compute

NVIDIA Jetson, CUDA, TensorRT

Simulation

Gazebo, Isaac Sim

Software & operations

C++, Python, Linux, Docker, Git and CI, fleet monitoring, remote assistance, over-the-air updates

You don't need all of these. Deep expertise in sensing and navigation matters most.

Nice to have

• Safety-rated sensors and functional safety: awareness of ISO 13849 and IEC 61508, and of service and mobile-robot standards such as ISO 13482 and ISO 3691-4.
• EMC and hardware bring-up.
• Working with sensor and hardware suppliers.
• Human-robot interaction, social navigation or people-following.
• Navigation in large indoor spaces: multi-zone maps, automatic doors or elevators.
• Experience from an early-stage startup.

Education & other skills

• BSc or MSc in Robotics, Electrical Engineering, Computer Science, Mechatronics or a similar field, or equivalent senior industry experience.
• Ownership from prototype to a field-tested solution, including hands-on testing at pilot sites.
• Clear written and spoken English. Swedish is a plus.
• Comfortable with the pace and ambiguity of an early-stage startup.
