Job description

Cardless is looking for an experienced backend engineer to join our exceptional team! You’ll play a key role in designing, building, and scaling the systems that power our co-branded credit card platform spanning domains like applications, accounts, transactions, fraud, risk, and rewards.

As a software engineer, your responsibilities will include but not be limited to the following:

Responsibilities

  • Design and build scalable, secure, and high-performance backend systems and services that support Cardless’s core financial products

  • Contribute to architectural discussions and decisions to evolve our platform as we grow

  • Take ownership of projects from design through production — including requirements gathering, implementation, testing, deployment, and ongoing maintenance

  • Collaborate cross-functionally with product managers, designers, other engineers, and stakeholders (external partners, risk, compliance) to deliver high-quality features quickly and reliably

  • Identify and drive improvements in system reliability, observability, performance, and developer experience

  • Provide technical guidance and thought partnership to peers across the engineering organization

What we look for

  • Strong experience designing and implementing backend systems and services that operate at scale (typically 5+ years of industry experience)

  • Solid understanding of distributed systems, APIs, databases, and infrastructure fundamentals

  • Proficiency with a modern backend language (e.g. Java, Python) and ecosystem

  • Track record of delivering complex technical projects end-to-end, collaborating effectively with cross-functional partners

  • Deep, low-level expertise in one or more backend domains (e.g., databases, scaling systems, distributed systems)

  • Passion for building robust, maintainable systems that have real-world impact for customers

Nice to have

  • Experience building and maintaining external, public-facing APIs

  • Familiarity with financial systems, reconciliation workflows, or data integrity challenges

  • Exposure to ML pipelines or feature stores
