About the role

Apex Fintech Solutions powers innovation and the future of digital wealth management by building tech-forward solutions that help simplify, automate, and facilitate access to financial markets for all. Our robust suite of fintech software enables us to support clients such as Stash, Betterment, SoFi, Webull, and eToro, amongst many others; collectively, Apex powers access to the stock market for over 22+ million end customers.

At Apex, we are changing how the securities industry operates by reinventing the status quo, which was manual, slow, and accessible only by the ultra-wealthy. We're digitizing and democratizing systems so that everyone has an opportunity to invest. When you're at Apex, you drive this change. You're part of a global team with a clear vision: to be the trusted technology that powers the digital economy.

Our technical writing staff sits at the leading edge of this disruption and is responsible for communicating the scope and impact of Apex's top-of-class financial infrastructure products and software solutions for technical and financial client personas. If you thrive off the energy of an enthusiastic, collaborative team and love to learn and solve problems, we want to hear from you.

As a Senior Technical Writer at Apex Fintech Solutions, you're responsible for developing technical documentation to support Apex's platform, including our APIs and the clients who use them. In addition to your expert skills in producing content for developer audiences, this role demands agility to support rapid software-development cycles. Your ingenuity and resourcefulness will be critical as you adapt to varying circumstances and shifting timelines and collaborate across multiple teams to achieve objectives. You excel in understanding the perspective of your audience, ensuring clarity and depth in your communications, and you possess keen curiosity and drive to continuously learn about the products you document.
