Job Description

Range is hiring for an Applied Scientist to accelerate our best-in-class AI system that delivers and automates financial products and solutions across the entire wealth management spectrum. This engineer will work with our AI team to both build and strategically influence the technology that ultimately powers Range’s disruptive platform.

Job Responsibility

  • Improve the accuracy, reliability, and sophistication of our AI-generated responses by iterating on models, prompts, and evaluation frameworks
  • Partner with product and engineering teams to design and develop new AI-first features that help users make better financial decisions
  • Help shape our data strategy, including how we collect, label, and leverage structured and unstructured data to train and evaluate models
  • Bring modern best practices in applied AI and machine learning to the team, and help us stay at the frontier as the AI landscape evolves

Requirements

  • Hands-on experience with modern LLMs and a strong perspective on their strengths, weaknesses, and evolving capabilities
  • Experience building production AI features such as retrieval-augmented generation (RAG), autonomous agents, user-facing chat interfaces, or task automation systems
  • Deep understanding of prompt engineering, evaluation techniques, vector databases, and orchestration frameworks like LangChain
  • Familiarity with fine-tuning, embedding models, and techniques to ground AI outputs in proprietary or financial datasets
  • Fluency with AWS services including EC2, ECS, RDS, DynamoDB, S3, and CloudWatch—or equivalent cloud platforms
  • Strong product sense: you’re motivated by helping users get smarter, faster answers—not just pushing the boundaries of ML for its own sake
  • Proven ability to tackle ambiguous problems, work independently, and bring structure to chaos in a fast-moving startup environment

Nice to have

Bonus points for experience with security, regulated industries like fintech, or building AI systems that meet compliance and reliability standards

What we offer

  • Health & Wellness: 100% employer-covered medical insurance for employees (75% for dependents), plus dental and vision coverage
  • 401(k): Retirement savings program to support your future
  • Paid Time Off: time to reset and recharge + most federal holidays
  • Parental Leave: Comprehensive leave policy for growing families
  • Meals: Select meals covered throughout the week
  • Fitness: Monthly movement stipend
  • Equity & Career Growth: Early exercise eligibility and a strong focus on professional development
  • Annual Compensation Reviews: Salary and equity refreshes based on performance
  • Boomerang Program: After two years at Range, you can take time away to start your own company. We’ll hold your spot for 6 months - and pause your equity vesting, which resumes if you return
