iOS Developer (CoreML / ML Model Integration)

About the company:

United Developers — for over 10 years, we have been creating, developing, and supporting mobile applications. Our clients are companies and startups from the USA and Europe. We pay special attention to two areas: developing applications for the Internet of Things (IoT) ecosystems and implementing solutions based on artificial intelligence and machine learning (AI/ML) into business applications.

About the role

We are looking for an iOS developer to help integrate ML models into mobile applications. This is not a research position: you do not need to train models from scratch. The main task is to convert ready-made ML models to CoreML, use them on the device, and write code for data pre- and post-processing.

Responsibilities

· Conversion of ML models (TensorFlow, PyTorch, etc.) to Apple CoreML format (.mlmodel).

· Integration and use of ready-made ML models in iOS applications.

· Writing code for data preprocessing and postprocessing (images, tensors, arrays, normalization, etc.).

· Working with numpy and Python to prepare, verify, and debug models.

· Optimization of ML inference performance on iOS (where possible).

· Interaction with the ML team / researchers to transfer models to production.

Requirements

· Commercial experience in iOS development using Swift.

· Practical experience with Apple CoreML: conversion, integration, use of models in real projects.

· Basic knowledge of numpy and Python.

· Understanding of ML model formats and the "training → conversion → mobile inference" pipeline.

· Experience with Vision, Natural Language, Create ML will be a plus.

· English B2.

Conditions

· Full-time employment

· Remote work.
