Senior Software Engineer

Overview

As a Software Engineer at 10x, you are passionate about working with cutting‑edge technologies, and bring deep technical knowledge and proven experience with data systems to deliver scalable solutions. This particular role is with the team responsible for the lending modules. Services run by this team support multiple types of lending products including credit cards, mortgages and unsecured loans. This requires complex orchestration with the interest calculation and fees engines as well as billing and regeneration of payment schedules. All of this needs to be highly performant and at scale. Additionally, to the technical side of the role, you bring experience and wisdom in mentoring junior developers and proven experience in the challenges of delivery of high‑quality software in a high‑performance and fast‑paced development environment.

We recognise that a better work/life balance can improve people’s motivation, performance and overall wellbeing. That is why, if there is scope in the working day, we have flexibility around our core hours to do the things that matter to you. We also know some work is done better at home and some is done better in the office, and that a one‑size‑fits‑all approach does not enable high performance. That is why 10x is a remote‑enabled organisation and supports agile working. This role has an office attendance requirement of approximately two days per quarter, in agreement with your line manager. Additionally, everyone comes together at our quarterly 10x Together Days to collaborate, align on strategy, and socialise.
