• Design and develop custom machine learning models that deliver business value on time and within scope.
• Build and maintain document processing pipelines, including data engineering components.
• Fine‑tune and implement recent vision‑language models (e.g., LLaVA, Deep Seek).
• Build and operate AI evaluation systems, comparing test versions of models to assess performance.
• Lead system‑level architecture decisions and own specifications to meet client expectations.
• Translate theoretical models into robust, scalable code (primarily in Python) within a cloud environment (AWS).
• Collaborate with cross‑functional teams, including business and technical stakeholders, to define actionable engineering plans in ambiguous settings.
• Mentor project teams, supporting both technical growth and project execution.
• Contribute to internal initiatives such as interviews, tooling, and process improvement.
• Stay current on advancements in ML, especially in computer vision and model evaluation.

• Must‑haves:
  • Strong experience with vision‑language models and document processing pipelines.
  • Experience building/operating AI evaluation systems.
  • Proficiency in Python, with ability to write clean, production‑ready code.
  • Experience working in cloud environments (AWS preferred).
• General qualifications:
  • 5‑7 years of experience for mid‑level, 8‑10 years for senior‑level.
  • Extensive professional experience building, designing, and deploying machine learning systems.
  • Strong software engineering fundamentals (OOP, version control, code hygiene).
  • Ability to communicate complex technical concepts clearly to both technical and non‑technical audiences.
  • Demonstrated success in client‑facing or stakeholder‑heavy environments.
  • Excellent time management and interpersonal skills.
  • Advanced degree (MS/PhD in Computer Science or related field) or equivalent work experience.

The pay for this W-2 position ranges from $80 - 105/hr depending on experience level.
