Staff Engineer, Software

Work Flexibility: Hybrid or Onsite

Job Description:

We are seeking an experienced engineer who brings two distinct skill sets: AI/ML (Computer Vision) - owning the training, testing, and tuning of vision-based models for live camera-feed monitoring; and Native Android Development - developing and shipping a production Android app that talks to our cloud. You will partner with the deployment team to align models with their scaling/runtime constraints, work with the maintenance team to maintain and upgrade models.

Key Responsibilities

• Design, train, evaluate, and tune computer vision models (detection, classification, segmentation, tracking) for live video and multi-camera use cases, including dataset curation, training/validation/testing pipelines, and rigorous benchmarking on accuracy, latency, and throughput.

• Optimize models (architecture, quantization, pruning, distillation) to meet deployment and scaling constraints provided by the deployment team; re-tune or re-architect when those constraints change.

• Partner with the operations team to maintain and upgrade models in production — triage regressions, refresh on new data, address drift, and ship improved versions.

• Design, build, and ship a native Android application (Kotlin, Jetpack Compose, MVVM/Clean Architecture, Hilt, Coroutines/Flow, Room, WorkManager) that interacts with our cloud backend.

• Build secure cloud integration: REST/gRPC, OAuth2/JWT, TLS, FCM push, and offline-first sync; handle Android runtime permissions and background execution correctly.

• Set up Android CI, testing (unit + instrumentation), crash reporting, and Play Store release pipelines.

Required Qualifications

• 5+ years of total professional software engineering experience.

• Proven experience in vision-based model training and testing, with models shipped to production.

• Hands-on experience with cloud-based AI training/experimentation infrastructure (AWS SageMaker, GCP Vertex AI, Azure ML, or equivalent).

• Experience building models for continuous monitoring via live video input from cameras and tuning them for efficient inference across multiple concurrent camera streams.

• Track record of collaborating with deployment/MLOps/operations teams - translating runtime constraints into model decisions and supporting models post-launch.

• Proficiency in Python and ML frameworks (PyTorch, TensorFlow, TensorFlow Lite, ONNX); strong grasp of CNNs and modern detection/tracking architectures (YOLO, DETR, ByteTrack, etc.).

• Strong proficiency in Kotlin and the modern Android stack (Jetpack, Compose, Coroutines/Flow, Hilt, Room, WorkManager); demonstrated experience shipping production Android apps to the Play Store.

• Deep working knowledge of Android Wi-Fi and BLE APIs.

• Experience with cloud connectivity on Android (REST, gRPC, WebSockets, or MQTT; OAuth2/JWT; TLS; FCM) and Android’s security/permissions model (runtime permissions, foreground services, background execution limits).

• Comfort interfacing with embedded/IoT hardware over BLE and WiFi under real-world conditions (intermittent connectivity, retries, power constraints).

Preferred Qualifications

• On-device inference acceleration (Android NNAPI, Qualcomm SNPE, MediaPipe, GPU delegates).

• Streaming protocols (RTSP, WebRTC, HLS) and video codecs; edge / IoT camera deployments.

• Model monitoring, drift detection, and active learning loops.

• Contributions to open-source ML or Android projects.

Education

• Bachelor’s or Master’s degree in Computer Science, AI/ML, or related field — or equivalent practical experience.

measurement bias

• Strong product mindset and bias for measurement - you instrument, benchmark, and optimize.

• Excellent collaboration skills with deployment and operations teams, and a maintenance mindset toward models in production.

• Ability to switch effectively between two distinct domains (ML model development and Android app development) and deliver in both.
