Senior Software Engineer | Backend

Apron is focused on helping small and medium businesses succeed. The biggest threat to small business is cash flow, often stemming from a gap between the demand payments put on owners and the aptitude to make the payments effectively. We are closing the gap by digitising and simplifying the payments process: capturing invoices, issuing expense cards, paying and getting paid, all in one place.

Engineering Culture

• We build with the customer in mind. We use top‑tier technology to build a product that genuinely makes their lives easier.
• We own our work. We plan the approach, break it down, and bring it to life.
• We embrace the complexity of finance. Working with money means navigating intricate business logic and thinking through every possible corner case. It’s a rewarding challenge where precision and attention to detail are crucial for building a trustworthy product.
• We write code we’re proud of. We work fast, but we build for the long term. Our code needs to be speedy, secure, and ready to grow with us.
• We integrate AI tools. We use what’s best out there to build a product that genuinely makes lives easier.

Responsibilities

• You’ll work cross‑functionally with Frontend Engineers, Product Managers and Product Designers to develop a variety of new and existing features end to end. Teams plan features implementation together and every voice matters.
• You’ll design systems for seamless integration with payment providers and BaaS platforms, ensuring scalability for market expansion.
• You’ll develop and optimise core financial integrations to guarantee customer funds are secure and transactions are routed with market‑leading speed.
• You’ll share your experience with others, driving innovation, proactively suggesting improvements.

Qualifications

• Keen attention to code quality, passion for efficient architecture, and commitment to optimising performance.
