Senior Product Engineer
Apron is focused on helping more 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.
We have grown quickly over the past few years, expanding our team to around 100 individuals across the UK, Germany, Spain and more. We are backed by Index Ventures, Bessemer Venture Partners, Zinal Grow and Tony Fadell and we’ve raised $50m.
Engineering Culture
* We build with the customer in mind, using top‑tier technology to deliver products that genuinely make lives easier.
* We own our work: we plan, break it down, and bring it to life.
* We embrace the complexity of finance, navigating intricate business logic and thinking through every possible corner case.
* We write code we’re proud of—fast, secure, and built for the long term.
* We integrate AI tools, using the best available to improve user experience.
What You’ll Own
* Own the full lifecycle: partner with Product Managers and Designers to shape the roadmap and translate customer needs into polished, end‑to‑end features.
* Build seamless financial experiences: design and integrate scalable systems with payment providers and BaaS platforms, making complexity invisible to the user.
* Engineer for trust and speed: develop core financial logic where precision meets performance, ensuring every transaction is secure, lightning‑fast, and intuitively handled.
* Drive the product narrative: proactively suggest improvements to the user journey, identifying hidden friction points and driving innovation across the stack.
* Cultivate a collaborative culture: mentor peers and advocate for best practices that prioritize system health and rapid product iteration.
What You’ll Need
* Solid experience as a backend‑leaning full‑stack engineer.
* End‑to‑end experience working in a cross‑functional squad, directly shaping user‑facing products.
* Experience delivered in a product‑led, fast‑paced environment (startup or tech company).
* Willingness to work on Kotlin and Typescript/React.
* Experience with relational databases.
* Keen attention to code quality, passion for efficient architecture, and commitment to performance optimisation.
