At Moment, we are modernizing capital markets infrastructure for the wealth management sector, starting with the fixed income asset class. Founded in 2022 by former fixed income quants, we provide global fintechs, brokerages, and RIAs with a seamless, end-to-end solution for data, execution, and portfolio management. While the fixed income market is massive and growing rapidly, it has long been held back by legacy technology. We are changing that by offering a modern, API-first platform that serves millions of retail investors. Backed by world-class investors like a16z, we are scaling quickly to transform how the world accesses financial markets.

Skills and experience
We are looking for candidates who possess a strong foundation in backend engineering and a drive to make a global impact. While a background in fintech is not required, we value a passion for innovation and a commitment to high standards.
- At least 5 years of experience in backend engineering, including building services from the ground up in large-scale production environments.
- Proficiency with our core tech stack, which includes Go, AWS, Kafka, and Postgres.
