Job description

Move Forward with Volt!
Volt is immediately hiring a Junior AI/ML Engineer in San Diego, CA.
As a Junior AI/ML Engineer, you will assist with:
  • Prototype and deliver generative AI and ML features that speed up engineering workflows and further development of our digital platform. This role emphasizes "vibe coding": rapid, AI-assisted iteration (copilots/code chat) with disciplined habits-small pull requests, quick feedback, and tests that keep prototypes safe as they mature.
  • Rapid prototyping ("vibe coding"): Build applications with AI-assisted coding tools, notebooks, and lightweight services; iterate in short cycles with frequent demos and feedback.
  • LLM features: Implement and test use cases like search, summarization, and Q&A over documents/logs with guidance from senior team members.
  • Integration: Package models into APIs/pipelines, work in a small-PR workflow, add unit/integration tests, and support deployment.

This is a full-time - long term temporary opportunity. The role will be on-site at the San Diego Facility.
Schedule: Monday - Friday - 8am - 5pm.
The ideal candidate will have:
  • Bachelor's degree in CS, Data Science, Mechanical Engineering, or related (or equivalent practical experience).
  • 1-2 years of experience (internships, co-ops, research, or early-career roles) building software, data pipelines, or ML prototypes.
  • Python proficiency with common data tools (Pandas/NumPy) and baseline software engineering practices (testing, readability).
  • ML fundamentals and strong interest in generative AI/LLMs (evaluation, failure modes, responsible use).
  • Exposure to PyTorch/TensorFlow or modern LLM tooling (Transformers, RAG/vector search libraries).
  • Comfortable using Git and collaborating via pull requests.

Preferred Skills:
  • AI-assisted prototyping ("vibe coding"): fast iteration with copilots/code chat, backed by tests, reviews, and lightweight evaluation.
  • Good AI-tool hygiene: write clear prompts, review diffs critically, and protect sensitive data.
  • Nice to have: RAG/embeddings and basic cloud/CI/CD exposure.

Pay Rate: $ 35.00-$48.00 Per Hour DOE
*Pay range offered to a successful candidate will be based on several factors, including the candidate's education, work experience, work location, specific job duties certifications, etc.
