Profile match
Finix gives software platforms the infrastructure to process payments themselves rather than reselling another provider's service. Its stack covers merchant onboarding, card acquiring, payouts and dispute handling under the platform's own brand. The company later became a registered payment facilitator so customers can go live without a separate acquirer.

About the role:

At Finix, we build for scale and develop systems that can process tens of thousands of events per second. Our systems move millions of dollars per day. We iterate quickly and constantly release new features with little to no margin for error.

As a member of the Support Engineering Team, you are the front line and the face of Finix. You will interact with customers daily and help them on their path to becoming payment processing platforms, all while improving the product by collaborating closely with the Revenue, Product, and Engineering teams.

We are looking for a candidate who is a payment nerd or is interested in being one. Additionally, successful candidates are natural problem-solvers and show a curiosity about how the industry works. They are excited to help our customers build their own perfect payments stack.

This hybrid role entails working in the office 4 days per week in our San Francisco HQ.

You will:

  • Collaborate with the Revenue, Product, and Engineering teams on projects, features, and tasks along with managing the Support ticket queue and answering tickets
  • Troubleshoot, debug, and document technical customer issues and solutions
  • Build strong relationships with Finix users, work with them to resolve their issues including identifying product gaps and enhancement, and work to implement solutions and improvements
  • Act as a customer advocate in cross-functional product meetings
  • Engage and participate in team learnings to better understand the payments ecosystem

You have:

  • BS/MS in Computer Science, Engineering, or similar experience (Open to DevBootcamp graduates and non-college graduates)
  • Experience working with RESTful JSON APIs, Curl Commands, SQL, scripting languages, debugging, log aggregators, and web technologies
  • Strong written and verbal communication skills. You believe in being open, honest, and direct in your communications
  • Comfortable working in a fast pace environment and interacting with a high volume of customers every day, team-oriented, and hungry to learn
  • Strong foundational knowledge of APIs and can explain the concept to a five-year-old easily
  • Experience with ticketing tools such as Hubspot

Bonus points if you have:

  • Previous experience working for SaaS companies
  • Payments experience
  • Python, Ruby, and/or JavaScript experience
