About the Role
We’re looking for a curious, broad-based Junior ML / AI Engineer to help shape how AI and machine learning can create leverage across a modern apparel business. This role sits within o5 group’s Technology & Innovation team and will partner closely with the Chief AI and Data Officer and cross-functional product teams.
This is a high-ownership opportunity for someone who is energized by ambiguity, enjoys solving open-ended problems, and wants to help define the roadmap—not just execute against it. You’ll contribute to early-stage exploration and practical implementation across demand forecasting, personalization, supply chain, customer experience, and internal productivity tools.
How You’ll Contribute
- Explore where machine learning and AI can create the most impact across the business, then help translate those opportunities into practical use cases and prototypes.
- Build and iterate on demand forecasting and inventory planning models that help reduce overproduction and stockouts.
- Support personalization and recommendation initiatives across the e-commerce experience.
- Develop or integrate LLM-powered tools for internal workflows, including product copy, search, customer support automation, and operational productivity.
- Contribute to computer vision and visual search opportunities tied to product imagery, fit, and customer experience.
- Help design AI agents and workflow automations that streamline repetitive processes across the organization.
- Create and maintain data pipelines and foundational infrastructure needed to support ML / AI experimentation and deployment.
- Partner cross-functionally to test ideas quickly, evaluate outcomes, and refine solutions based on business value.
What You Bring to the Team
Required:
- Bachelor’s degree in computer science, data science, mathematics, or a related technical field, or equivalent practical experience.
- 1–3 years of professional or research experience in ML, AI engineering, or data science; coursework, bootcamp work, and independent projects may be considered alongside professional experience.
- Strong Python and SQL skills.
- Experience with traditional ML approaches such as scikit-learn and XGBoost.
- Hands-on experience with model training, evaluation, and tuning.
- Working knowledge of at least one cloud platform (Azure, AWS, or GCP).
- Git / version control proficiency.
- Strong grounding in statistics and probability fundamentals.
Strong Plus:
- LLM integration experience using platforms such as OpenAI or Anthropic.
- RAG pipelines and familiarity with LangChain or LlamaIndex.
- Vector databases such as Pinecone, FAISS, or Chroma.
- AI agents and tool use.
- PyTorch or TensorFlow.
- REST API development using FastAPI or Flask.
- Docker and experiment tracking tools such as MLflow or Weights & Biases.
Nice to Have:
- Fine-tuning approaches such as LoRA / QLoRA.
- Computer vision, NLP / text classification, time-series forecasting, or recommendation systems.
- Prompt engineering, Kubernetes, and Hugging Face Transformers.
- Retail / e-commerce domain knowledge.
You’ll be especially successful in this role if you are:
- Comfortable with ambiguity and able to help define the work—not just wait for a fully scoped ticket.
- Broadly curious across ML and AI, with the judgment to choose the right tool for the problem.
- A builder who cares about shipping practical solutions, not just optimizing offline metrics.
- A clear communicator who can translate technical concepts for cross-functional business teams.
- Able to show what you’ve built through projects, coursework, internships, or prior hands-on work.
