Senior Localization Software Engineer

About the role

Robotics software company developing platforms for autonomous mobile robots. The team builds the software stack that drives fleets of autonomous mobile robots in real-world deployments such as airports and industrial warehouses, currently evolving the platform from ROS1 to ROS2 to improve robustness and scalability.

What you will do

• Improve the robustness, accuracy and stability of deployed localization and mapping solutions
• Analyse recurring localization and navigation failures and trace them to their algorithmic root cause
• Ensure algorithms perform well on large volumes of real and synthetic sensor data across diverse environments
• Improve the testability and quality of localization algorithms, including metrics and simulation-based validation
• Support the migration of the robotics stack from ROS1 to ROS2
• Debug issues across ROS1, ROS2, Docker and Linux layers, and improve recovery and fault-handling strategies
• Support customer deployments remotely (no travel expected)

What are we looking for

• Localization software engineering — 5+ years
• ROS1 and ROS2 — 3+ years
• Modern C++ (C++14 or later)
• Python
• Solid foundation in 3D computer vision, 3D geometry, multi-view geometry, structure from motion, SLAM or pose estimation
• Experience with large-scale sensor data (camera, perception outputs, vehicle poses, IMU, lidar or map data)
• Linux (Ubuntu) debugging, logs, profiling and performance analysis
• Git workflows and CI/CD
• Root cause analysis and automated testing (unit/integration)
• Real-world deployment experience of robotics/localization systems at customer sites
• English C1

Nice to have

• Experience building maps, 3D reconstruction, perception systems or sensor-fusion pipelines for robotics or autonomous driving
• Background in large-scale mapping, map fusion, change detection, road topology or semantic map generation
• Filter design and Bayesian processes
• Experience with safety PLCs, software watchdogs, health monitoring and diagnostics
• AMR (autonomous mobile robotics) industry experience
• Automated simulation validation

About KWAN

At KWAN, your career is bigger than one project. You join a real team, on a long-term project, at a company where technology is the business. And when you are ready for something new — a new stack, a new industry, a bigger role — we find that next step with you, without you having to start over somewhere else.

From day one you have a dedicated People Experience Partner: one person accountable for your growth, not your allocation. They know where you want to go, and they help you get there.

You keep learning as technology moves (AI included). Your impact is seen and recognised. Pay and expectations are talked about openly. And you work remote-first, with hubs in Lisbon and Porto for when you want people around.

Grow with clarity. Be treated with respect. Build things that matter.

Apply — if your profile is a match for this role, you will hear from our Talent team within 48 hours. If it is not the right match this time, we will reach out as soon as we find a role that fits you better.
