Flourish provides innovative access to financial products that help Registered Investment Advisors secure their clients'
The Role

Since 2017, Flourish has been on a mission to help financial advisors evolve from holistic advice to holistic implementation to better serve their clients and grow their businesses. 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 1,100 RIAs that collectively represent more than $2.6T in assets under management across three products: Flourish Cash, Flourish Lending, and Flourish Annuities. 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 dynamic, 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 an understanding of at least one business line and partner with product managers and fellow engineers to solve complex business problems with software and deliver commercially feasible solutions. Working with other engineers, you will bring ideas from the whiteboard to reality, providing input to key architectural decisions, extending existing features, developing entirely new services and applications, and performing code reviews. You have working 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.

  • Bachelor's Degree in Computer Science, Math, Physics, or Engineering or equivalent working experience

  • Solid understanding of modern database technology (Redis, Postgres, RedShift, BigQuery)
  • Ability to design intuitive and performant RESTful APIs
  • Ability to work independently and as part of a fast moving team
  • Ready to learn, but just as ready to teach
  • Due to the nature of this position, as part of the background check process, candidates must be able to pass a fingerprint background check to qualify as a fingerprinted person under FINRA. For roles requiring registration, additional regulatory screenings may apply, including a review of Form U5 disclosures and other relevant licensing information.
Preferred Qualifications
  • MS or PhD in Computer Science, Math, Physics or Engineering
  • Understanding of common SSO protocols (OAuth, OIDC, SAML)
  • Pandas/SciPy/Django experience
  • NoSQL experience (We use DynamoDB and Redis)
