Additional Information

We Are Sparta Sparta is the next-generation commodity trading platform. We give trading desks the clarity, control, and collaboration they need to move faster and trade smarter. In February 2025, we secured $42 million in Series B funding. Now we're scaling up across the business, and it's an exciting time to join. Our people are the driving force behind everything we do. At Sparta, you'll be trusted to take ownership, backed by a team who wants you to succeed. You'll be challenged, supported, and given room to grow. Because building something this ambitious takes everyone at their best. At Sparta, your work has reach. From improving our platform, to powering smarter decisions for our customers, to changing how commodity trading is done around the world. And because we're growing fast, you won't just build your career. You'll accelerate it, with a level of ownership and impact you simply don't get at bigger, more bureaucratic companies. Staff Backend Engineer At Sparta, we're on a mission to build the next generation of commodity trading platforms - replacing the fragmented tools that traders typically rely on with a single, powerful dashboard. Our product is a data-driven platform that aggregates real-time feeds from across the commodities domain, transforming them into intuitive, actionable visualisations within one unified interface. Users can explore pre-built data views or define their own custom formulas to create tailored insights. To deliver on this vision, our engineers tackle significant distributed systems challenges on a daily basis, where designing for reliability and performance at scale is essential to ensuring a seamless user experience. As we unlock the next level of scale, these challenges become even more critical. We're looking to bring on senior engineers with experience building data-intensive applications at scale to help drive this next phase of growth. We're also looking for people who thrive in an empowered environment - individuals who are comfortable being given problems to solve rather than solutions to implement. You should enjoy working at pace, value autonomy, and prefer to ask for forgiveness rather than permission. As a senior member of the team, you'll be comfortable contributing to the product direction, engaging with stakeholders, and playing a key role in mentoring and developing our more junior engineers. Whereas Sparta is a remote-first company, for this role we're looking for someone who values a hybrid working style, which in a typical week could involve spending a couple of days in the office - with flexibility built in.
