ABOUT THIS ROLE
At Apex Fintech Solutions, we've got an amazing track record of success and fostering ongoing innovation. 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.
The Senior Technical Writer role will lead the creation and evolution of technical documentation for our technology products, APIs, platforms, and client experiences. You will partner with engineers, product managers, architects, and business stakeholders to translate technical concepts into clear, accurate, user-focused content.
As a senior member of the team, you will lead by example — consistently delivering high-standard content that adheres to our writing guidelines and mentoring less experienced team members. You will also combine strong technical writing expertise with hands-on use of artificial intelligence to improve documentation quality, accelerate content development, streamline workflows, and enhance the overall experience.
