  • Design smart team workflows: Partner with teams across Finance, Legal, Customer Success, and Revenue Operations to engineer tools tailored to their evolving processes.
  • Help set AI engineering practices: Collaborate on best practices for integrating AI-generated code into the codebase, sharing methodologies that elevate velocity across the wider engineering team.

What you bring

  • Modern AI development habits: Daily experience using AI coding agents to accelerate development, paired with a sharp eye for code quality, security, and architecture.
  • Testing & evaluation rigor: Hands-on experience creating robust automated tests and developing benchmarking tools for non-deterministic model outputs.
  • Production LLM experience: Practical knowledge building on LLM APIs, including prompt design, output parsing, performance tuning, and cost management.
  • Full-stack problem solving: Ability to take open-ended business needs and turn them into fully functional, user-friendly internal tools.
  • Maintainable engineering: Dedication to writing readable, modular, and well-instrumented code that remains easy for others to collaborate on.
  • Agile, evolving mindset: Excitement to try new tooling, adapt to changing requirements, and continuously improve how internal tools are delivered.

Experience and qualifications

  • 5+ years of professional software engineering experience, including ownership of production software systems.
  • Consistent experience using AI coding agents or assistants as part of a modern software development workflow.
  • Experience building automated testing workflows or evaluation systems for AI/LLM applications.
  • Hands-on experience integrating large language model APIs into user-facing applications or internal platforms.
  • Experience building internal applications, workflow automation, or platform services used daily by non-technical teams.
  • Proficiency in Python and modern frontend frameworks (e.g., React), alongside practical experience with web APIs and cloud integrations.
  • Experience with document processing, contract workflows, or legal technology is a strong plus.
  • Bachelor's degree in computer science or a technical field, or equivalent practical experience.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
