Senior Full Stack Engineer

Flourish
New York, NY





Since 2017, Flourish has been on a mission to help financial advisors better secure the financial futures of their clients. We focus on independent Registered Investment Advisors (RIAs), delivering financial products that advisors can’t easily access today through beautiful, scalable, and easy-to-use technology.

Today, we work with over 850 RIAs that collectively represent more than $1.5T in assets under management across two products: Flourish Annuities and Flourish Cash. Headquartered in New York City, we are an independently-operating, wholly-owned subsidiary of MassMutual Life Insurance Company.

Read on if you are interested in joining a small, highly-collaborative, rapidly-growing startup—backed by the support and stability of a Fortune 500 company.

About You


You are an engineer, first and foremost. You can rapidly build products that will delight users, with best practices in terms of both development and security. You thrive in a work environment that requires strong problem solving skills and independent self-direction, coupled with an aptitude for team collaboration and open communication. You are a strong communicator, explaining complex technical concepts to designers, support, and other engineers is no problem for you.

You possess strong computer science fundamentals: data structures, algorithms, programming languages, distributed systems, and information retrieval. And finally, your accomplishments are much more important than your paper credentials.

About the Role


Our mission is to provide innovative access to financial products that help RIAs secure their clients’ financial futures and the Flourish Engineers play a key role in doing just that. We’re seeking backend and full-stack engineers to help build a scalable platform. Cross functional collaboration is key to success and you will collaborate with teams across the organization, including Product, Design, Operations and Risk.

You will develop a deep understanding of at least one business line and partner with product managers, business leaders, and fellow engineers to solve complex business problems with software and deliver commercially feasible and viable solutions. Working with other engineers, you will bring ideas from the whiteboard to reality, making key architectural decisions, extending existing features, designing and developing entirely new services and applications, and performing code and architecture reviews. You have deep knowledge of distributed systems and application service frameworks, and are excited to work throughout the tech-stack to deliver a delightful experience for customers and coworkers.
