WHO
we’re looking for:

We are
looking for an Android AI ML Engineer - On-Device who will be responsible for helping build intelligent, privacy-first mobile systems that can detect, respond to, and learn from dynamic real-world conditions. This role involves deploying resource-efficient ML models directly on Android devices, combined with backend integration for model management, telemetry, and secure update delivery. The ideal candidate has a strong background in on-device intelligence and cloud-integrated systems, especially in applications that require responsiveness, adaptability, and strict privacy controls.

Role
and Responsibilities:

• Design, develop, and deploy on-device machine learning models optimized for Android, ensuring low latency and minimal resource consumption.
• Build robust and scalable ML pipelines using Android-native frameworks such as:

• TensorFlow Lite
• ML Kit (including GenAI APIs)
• MediaPipe
• PyTorch Mobile

• Build robust and efficient on-device data pipelines and inference mechanisms for real-time decision-making.
• Apply model optimization techniques such as quantization, pruning, and distillation for performance on mobile hardware.
• Ensure privacy-first design by performing all data processing and inference strictly on-device.
• Collaborate with backend teams to integrate with cloud-based model orchestration systems (e.g., MCP or similar) for:

• Model versioning, delivery, and remote updates
• Telemetry collection and model performance monitoring
• Rollout and A/B testing infrastructure

• Implement secure local storage, encrypted data handling, and telemetry pipelines that meet privacy and compliance standards.
• Support adaptive model behavior through on-device fine-tuning, personalization, or federated learning workflows.

Required Experience and Education:

• 5-7 years of experience with a Masters degree, 3+ years of experience with a PhD.
• Proficiency in Android development using Kotlin and/or Java is a plus with deep understanding of app architecture, background processing, and system APIs.
• Hands-on experience with on-device ML frameworks: TensorFlow Lite, ML Kit, MediaPipe, PyTorch Mobile.
• Solid understanding of mobile performance optimization, including model size, memory usage, and latency.
• Proven ability to integrate Android apps with backend/cloud systems for:

• Model lifecycle management (delivery, updates, rollback)
• Logging, telemetry, and analytics

• Experience with secure Android development, including permissions, sandboxing, encryption, and local data protection.
• Strong understanding of privacy-first ML system design and local-only data processing.

Necessary Skills and Attributes:

• Self-motivated
  individual with the ability to thrive in a team-based or
  independent environment.
• Detail-oriented with strong
  organization skills.
• Ability to work in a
  fast-paced environment.
• Limited supervision
  and the exercise of discretion.

Preferred Qualifications:

• Experience working with model orchestration platforms (e.g., MCP, Vertex AI, SageMaker, or internal tools).
• Familiarity with federated learning, on-device personalization, or differential privacy.
• Background in building real-time, data-driven features in mobile apps at scale.
• Familiarity with cloud infrastructure (e.g., GCP, AWS) for ML model deployment and monitoring.
• Previous work in high-sensitivity domains such as identity, privacy, mobile security, or regulated industries is a plus.
