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:

• →

  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

• 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

• 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

You’ll join a collaborative, fast-moving team that values craftsmanship, curiosity, and impact. We’re building products that enable leading brands to offer credit in new ways — and we’re just getting started.
