Our Story Hello there. We’re Zopa. We started our journey back in 2005, building the first ever peer-to-peer lending company. Fast forward to 2020 and we launched Zopa Bank. A bank that listens to what our customers don’t like about finance and does the opposite. We’re redefining what it feels like to work in finance. Our vision for a new era of banking puts people front and centre — we’ve built a business that empowers everyone to aim high, every day, to move finance forward. Find out more about our fantastic offerings at <a class="postings-link" href="http://Zopa.com">Zopa.com</a>!  We’re incredibly proud of our achievements and none of it would be possible without the amazing team here. It’s not just industry awards we’re winning, we’ve also been named in the top three UK’s Most Loved Workplaces.  If you embrace unconventional challenges, are unafraid to think differently and are driven to make an outsized impact, you’ll thrive here at Zopa, so join us, and make it count. Want to see us in action? Follow us on Instagram @zopalife The engineering challenge You will design and evolve the services that power core banking products. The systems you help build process thousands of financial transactions every day. They must be scalable, resilient and secure. When money moves, it has to work. Every time.  But this role goes beyond implementation.  You will shape technical direction. Influence cross-team initiatives. Own complex, high-impact work from concept through to production. You will help decide not just how we build, but what we build and why.  This is senior in impact, not just title.  We’re growing across several of our product-engineering tribes at Zopa, with current opportunities in Current Accounts, Lending, Credit Cards and Product Enablement.  We care deeply about great engineering, which is why our core stack is Kotlin, running on a modern platform with Kafka, Kubernetes, Docker and AWS Aurora Postgres. But great engineers aren’t defined by a single language which is why we are agnostic with our hiring. We want the right people, not the 'right' language, so if you come from a C#/.NET background, bring solid fundamentals, and have an appetite for learning something new, we’ll invest in you, help you grow your skills and confidently step into our Kotlin ecosystem. \n Your impact:<div> <div> <div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1" role="listitem"> Owning complex initiatives end to end, from idea to measurable outcome  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="2" data-aria-level="1" role="listitem"> Designing scalable backend systems that stand up to real-world scale and complexity  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="3" data-aria-level="1" role="listitem"> Making architectural decisions that balance immediate delivery with long-term sustainability  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="4" data-aria-level="1" role="listitem"> Bringing structure and clarity to ambiguous problems  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="5" data-aria-level="1" role="listitem"> Influencing prioritisation and trade-offs across teams  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="6" data-aria-level="1" role="listitem"> Raising the bar for engineering quality, reliability and accountability  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="7" data-aria-level="1" role="listitem"> Mentoring engineers and strengthening overall team capability  </li> </ul> </div> <div> <ul role="list" style="list-style-type: disc;"> <li aria-setsize="-1" data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="8" data-aria-level="1" role="listitem"> Driving continuous improvement in how we build and operate systems </li> </ul> </div> </div> </div> </div> Your toolkit:<ul> <li>You'll work with C#, Kafka, Kubernetes, Docker, AWS Aurora Postgres, and other modern technologies.
