This position reports to the Director, Applied Generative AI and will work closely and independently with assigned client teams in R&D.

This is not a traditional software engineering role. We are building a new kind of team small, fast-moving and AI-first. The person in this role should be comfortable working independently with client teams, building strong relationships with stakeholders, and helping define new ways of working in an AI-native environment. This is an on-site role in San Diego.

Responsibilities

• Partner directly with R&D stakeholders to identify, scope, and deliver high-value AI use cases across scientific workflows, knowledge access, decision support, and drug discovery.
• Build AI-enabled applications, assistants, automations, and data products that improve scientific productivity and accelerate research.
• Work independently with client teams to understand workflows, gather requirements, iterate quickly, and ensure solutions fit real business needs.
• Contribute to larger AI initiatives in drug discovery, including model-driven approaches for scientific understanding, prediction, and prioritization.
• Help evaluate, prototype, and apply frontier models, agent frameworks, and AI engineering tools to real research problems.
• Support development of novel internal AI capabilities, including domain-adapted models, specialized workflows, and, where appropriate, foundation-model efforts.
• Collaborate with internal and external technical partners, where appropriate, to evaluate tools, models, and opportunities for partnership.
• Connect AI systems to internal data, documents, and research infrastructure to create practical, scalable solutions.
• Help deploy, monitor, and improve solutions in approved internal environments.
• Document technical patterns, decisions, and reusable approaches, and contribute to team standards for delivery, quality, and guardrails.
• Stay current on the latest developments in agentic coding, AI-assisted development, and frontier AI tools, and help raise the team's collective capability over time.

Required Qualifications

• Bachelor's, Master's, or PhD in Computer Science, Machine Learning, Engineering, Computational Biology, Bioinformatics, or a related technical field.
• Recent graduate or early-career candidate strongly preferred; 1-2 years of experience in a technical role may be beneficial.
• Strong computer science fundamentals, including programming, data structures, algorithms, and software design.
• Strong Python skills and the ability to build working applications and prototypes quickly.
• Academic, research, internship, or project experience in machine learning, AI applications, software engineering, or computational research.
• Hands-on experience using modern AI tools, LLM APIs, coding agents, and AI-assisted development environments.
• Familiarity with tools such as Claude Code or Codex, and comfort using them as part of day-to-day development.
• Up-to-date knowledge of the latest developments in agentic coding, AI-assisted software development, and frontier AI tooling.
• Ability to work independently with business stakeholders and operate effectively in a highly iterative, fast-moving environment.
• Strong communication and interpersonal skills, with the ability to build trust and work effectively with scientific teams.

Preferred Qualifications

• Demonstrated interest in frontier AI, model development, or applied ML through coursework, research, open-source work, publications, internships, or significant projects.
• Experience working on scientific, life sciences, computational chemistry, biology, or data-intensive technical problems is a plus.
• Familiarity with building internal tools, automation workflows, or AI-enabled applications in research or enterprise settings.
• Curiosity about how frontier AI can be applied to scientific discovery and drug development.
