A note before you apply

We're hiring Software Engineering Interns! This is a full-time salaried 12 month internship where you'll work closely with our Engineering, Product, and Design teams to build real features, solve real problems, and contribute to products that make a difference.

This listing represents multiple openings and for standout interns our goal is to convert this into a full-time engineering role at the end of the program.

About Clerkie

Clerkie is a fintech startup on a mission to democratize financial wellness using the power of artificial intelligence. Launched in 2018, Clerkie began with an app, aiming to help the nearly 123 million underserved Americans in need of financial guidance. Since its inception, the company has expanded its services and now pairs consumer guidance with cutting-edge B2B software. By pairing the two through the Clerkie network, these tools have become the go-to resource for creditors looking to manage loan losses while simultaneously helping millions of borrowers get out of debt.

Clerkie is a remote-first company, with over 40 employees spanning 4 time zones across the United States. To date, the company has raised $41 million, including a $33 million Series A round in early 2023. Investors include leading financial and venture institutions, including Citi Ventures, Left Lane Capital, Wellington Ventures, Flourish Ventures, and Vestigo Ventures.

This isn't just another internship - it's an investment in your growth. The ideal Clerkie team member is curious, collaborative, and eager to grow in a fast-paced environment. Clerkie's culture values a customer-first mindset and a bias for action - we're looking for someone who's excited to dive in and learn.

  • Optimize performance and ensure a seamless, user-friendly experience
  • Write clean, well-structured, and maintainable code with a strong emphasis on scalability and security

  • Proficiency in JavaScript/TypeScript and experience with React.js, Next.js, or Node.js
  • Comfortable working with databases (SQL or NoSQL, e.g., PostgreSQL, MongoDB)
  • Ability to manage project priorities, meet deadlines, and deliver results independently
  • Excitement for being part of a small, fast-moving team where every day brings new challenges and opportunities to learn and grow
Preferred qualifications (ranked by priority and not required):
  • Personal or school projects involving full-stack development
  • Exposure to AWS, Docker, or CI/CD pipelines
  • Experience with testing frameworks (Jest, Mocha)
  • Interest in fintech or financial literacy
Other adds
