Our mission

To deepen the understanding of our changing planet and inspire meaningful action.

 

What we do

  • We’re helping the world become more resilient to the impacts of physical climate risks (including floods, fires, storms and more). In doing so, we help drive positive global impact aligned to many of the UN’s Sustainable Development Goals (SDG’s).
  • Our team builds cutting-edge, peer-reviewed science (incorporating climate projections, remote sensing data) and translates that into financial impacts (to the value of assets or business disruption linked to failure of critical infrastructure) that our customers in the financial services industry use to identify, manage and mitigate those risks.
  • Climate X’s customers include the world’s largest banks, asset managers and insurance companies including CBRE, Standard Chartered, Virgin Money and Federated Hermes, as well as a partnership ecosystem that includes Deloitte, Capgemini and AWS. Combined, they manage over $6.5 trillion of assets.
  • Customers choose us thanks to our ecosystem of products that help solve real human problems and drive tangible business benefits. They love our customer-centric mindset, as well as our pace of innovation in the market.

  • Lead on technical direction for Carta's ML components, helping the team make the right choices on GenAI model application, prompt engineering, evaluation frameworks, tooling, infrastructure, and processes.
  • Shape and refine our approach to NLP and LLM development for information extraction, validation, and enrichment, including the potential fine-tuning of LLMs on domain-specific data to improve Carta's outputs.
  • Work closely with Product and Engineering leadership to align Carta ML initiatives with product goals and business outcomes, ensuring your work directly contributes to solving core customer problems.
  • Mentor, coach, and support the development of team members working on Carta's ML aspects; this includes providing regular technical and performance feedback, guiding their career development in partnership with the VP, and fostering a high-performing, collaborative culture.
  • Ensure our Carta ML pipelines are scalable, reproducible, and well-documented, working with engineering to establish robust MLOps practices for these specific systems.
  • Act as the go-to expert for ML problem-solving within the Carta context, helping team members navigate complex challenges in data extraction and validation.
  • Foster a culture of experimentation and innovation for Carta's ML, where the team can test new approaches and learn quickly to improve asset mapping capabilities.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
