Senior Android Developer

Are you ready to build a mobile platform where real-world data capture truly matters? 

Groundhawk is looking for a Senior Android Developer to develop and evolve our core 3D scanning Android application. The application is central to Groundhawk’s solution — it’s where field workers capture the data that feeds our machine learning pipelines and becomes the trusted source of underground infrastructure information. 

This is a technical ownership role. You will lead architecture decisions, work close to sensors and hardware, and ensure reliable, high-performance data capture in demanding construction environments. 

ABOUT GROUNDHAWK

3D scanning and AI-driven reality capture are transforming how underground fiber and electricity networks are mapped and documented. As infrastructure projects scale across Europe, accurate and verifiable underground data has become critical. 

Groundhawk delivers precise underground data for infrastructure owners, contractors, and utilities across Europe. Our platform processes large volumes of 3D data and turns them into actionable insights used directly in real construction projects. 

YOUR MISSION

Your mission is to own and advance the Android platform that powers Groundhawk’s field data capture. You will build robust, high-performance 3D scanning capabilities that work reliably in real-world conditions, where accuracy, usability and offline functionality are essential. 

WHAT YOU’LL DO 

• Develop the 3D scanning Android application together with the full solution R&D team 
• Design features that function reliably in construction environments with limited connectivity 
• Build real-time positioning systems, integrating GNSS, IMU data and custom hardware 
• Implement on-device ML and computer vision for real-time processing 
• Design and maintain offline-first architecture with intelligent data synchronization 
• Build intuitive UX for field use, including gloves, bright sunlight and time-critical workflows 
• Work with photogrammetry and Structure from Motion (SfM) techniques 
• Collaborate with ML, backend and QA teams on model deployment, data pipelines and device testing 
• Drive technical decisions related to architecture, performance and code quality 

WHAT WE’RE LOOKING FOR 

• 8+ years of professional Android development experience 
• Expert-level Kotlin skills and deep understanding of Android SDK internals 
• Experience with hardware integration (Bluetooth, USB, serial communication) 
• Strong understanding of sensor APIs: GPS/GNSS, accelerometer, gyroscope, camera 
• Proven experience building offline-first, performance-optimized mobile applications 
• Ability to work independently and take ownership of complex technical systems 

It is considered a strong advantage if you have:

• Experience with GNSS / RTK positioning, computer vision or 3D capture 
• Experience with on-device ML inference and sensor fusion 
• Familiarity with iOS development 
• Experience using AI-assisted coding tools (such as Cursor or GitHub Copilot) 

WHY GROUNDHAWK

• Technically demanding problems: sensor fusion, 3D capture and computer vision on mobile 
• Real-world impact — your work supports infrastructure projects that power communities and reduce CO₂ emissions 
• A VC-funded startup with product–market fit, paying customers and an ambitious roadmap 
• Growth paths toward mobile leadership or deeper specialization in ML and computer vision 
• A highly capable team with a low-hierarchy culture and close collaboration across roles 
• Remote-first and async by default — we trust you to manage your time and deliver results
