Perception Engineer / LiDAR / Python / C++ / Computer Vision

Location:

Wallingford – Oxfordshire – Hybrid (Permanent)

At Dexory, we are transforming the warehousing and logistics industry through data intelligence.

We are recruiting perception engineers who are curious, technically sharp, and comfortable operating between research and production. You need strong fundamentals – 3D geometry, signal processing, computer vision, or machine learning – and a motivation to build reliable perception systems in messy real‑world environments.

Offices are based in Wallingford, Oxford, but flexible set‑ups are accepted.

• Perception pipeline development: develop and improve systems for point cloud processing, object detection, and scene understanding in warehouse environments, working across both classical and learning‑based approaches.
• Sensor data analysis: work directly with 3D LiDAR scans and camera streams to debug, evaluate, and improve system behaviour across a growing fleet of customer sites.
• Data collection and labelling: contribute to workflows that build and maintain the datasets underpinning both classical and learned perception components.
• Cross‑team collaboration: work closely with robotics engineers to integrate perception capabilities into the broader ROS2‑based autonomy stack and ensure robust end‑to‑end behaviour.
• Experimentation and evaluation: run structured experiments, track results, and bring rigour to how we measure accuracy improvements and regressions across diverse warehouse environments.
• Tooling and debugging: build and maintain tools to support analysis, visualisation, and debugging of perception system performance in the field.
• Technical engagement: stay current with relevant research and emerging techniques, sharing findings with the team and contributing to the perception roadmap over time.

• 3D perception, point cloud processing, or sensor fusion (e.g., LiDAR, depth cameras, IMU)
• Computer vision using classical or learning‑based methods (OpenCV, PyTorch, Tensor Flow)
• Machine learning or deep learning, particularly applied to spatial or structured data
• Robotics development, including familiarity with ROS or ROS2

• Strong Python skills; C++ is a meaningful advantage given the performance‑critical nature of the work.
• Solid engineering fundamentals: clean, testable code, careful attention to edge cases, and genuine ownership of quality.
• A practical mindset: comfortable bridging theory and implementation, and able to make progress without perfect data or perfect problem definitions.
• Good communication: able to explain technical reasoning clearly to colleagues with different backgrounds and engage with feedback constructively.

You should be comfortable travelling to customer warehouse sites, domestically and internationally, to observe system behaviour and gather ground truth data in real deployment environments.

• Experience with SLAM, occupancy mapping, or related localisation techniques
• Familiarity with PCL (Point Cloud Library) or Open3D
• Familiarity with foundation vision models for segmentation or detection (e.g., SAM2) and how to apply them in production contexts
• Exposure to MLOps tooling – experiment tracking (MLflow, W&B), dataset versioning, model deployment
• Academic or project work in robotics, autonomous systems, or applied ML
• Interest in warehouse logistics, supply chain, or industrial automation

• Private healthcare via Bupa with 24/7 medical helpline
• Life insurance
• Income protection
• Pension: 4 % employee contribution with option to opt into salary exchange, 5 % employer contribution
• Employee Assistance Programme – mental wellbeing, financial and legal advice/support
• 25 days holiday per year + bank holidays
• Full meals onsite in Wallingford
• Fun team events on and offsite, snacks of all kinds in the office
