The Role
Entry-level software engineering role for new graduates joining Affirm’s Instruments team. Responsibilities include contributing to team projects, writing clear and well-tested code, navigating large codebases, debugging, participating in code reviews, collaborating with global stakeholders, communicating trade-offs, and balancing delivery speed with system quality and reliability. The role is hybrid in London during the early-career program, with future remote or office flexibility.
Summary Generated by Built In

At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most.

Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest.
We’re excited to welcome a new cohort of graduates with a computer science or related major who are ready to leverage their skills to drive real-world impact and shape the future of finance!
In our hybrid early career program, you’ll be paired with a tenured Affirmer and have an opportunity to collaborate in-person 3 days a week out of our London office. You'll experience the best of both worlds: the in-office experience and remote work. After the one-year, you can remain hybrid, go remote, or stay in an office. Opportunities are available across different tech stacks and teams so that you can find a perfect fit to launch your career with Affirm!


What You'll Do

  • With the support of your team, you will work on tasks that contribute to the team's projects and goals.
  • You will work collaboratively and proactively with your team and stakeholders, bringing them along for your work and helping to create visibility and dialog regarding the risks and trade-offs related to your work. 
  • You will strike the right balance of speed and quality in your work, ensuring that we hit our business goals while protecting our systems from downtime.
  • You will contribute to a sense of community on your team by engaging in growth and development activities. 

What We Look For

  • You have mastered taking a simple problem or business scenario into a solution that interacts with multiple software components, and executing on it by writing clear, easily understood, well tested and extensible code.
  • You are comfortable navigating a large code base, debugging others' code, and providing feedback to other engineers through code reviews.
  • Your experience demonstrates that you take ownership of your growth, proactively seeking feedback from your team, your manager, and your stakeholders.
  • You have strong verbal and written communication skills that support effective collaboration with our global engineering team.
  • This position requires either equivalent practical experience or a Bachelor’s degree in a related field.

GBR base pay range per year: £80,000 - 118,000 

Location (Hybrid): London
