What the job involves

• At Kinsworth, we aren’t just building software; we’re building a product customers love and a successful business. To achieve this, we operate at pace, we're big believers in autonomous teams and iterative development. We're crazy about continuous improvement and knowledge sharing, and we want people who share our enthusiasm
• We strive to always build the right thing and build the thing right, so we place great emphasis on understanding exactly what our customers need and delivering quality products that exceed their expectations
• We think that high-performing teams operate best through a model of build-it and run-it that comes from a deep curiosity about how our products work and how our customers use them. We use this foundation to build comprehensive product knowledge and industry expertise, but we're not dogmatic about it
• We operate in build squads that operate independently but are aligned to the same goals and ways of working. We recognise that different drives guide our roadmaps from customer needs to commercial strategy to regulatory change, and managing those dependencies is best achieved through aligned team decisions
• We make customer success everyone's business — what we are going to do and how we do it are team decisions

• Building and maintaining exceptional customer relationships through team excellence
• Zero-to-one function building — creating product delivery frameworks, engineering performance systems, and product delivery processes from the ground up
• Building and leveraging AI technology to enhance product features and development workflows
• We build with technology like:
• Python & ML / LLM ecosystem — service based solutions
• Event-driven — real-time data driven solutions
• Cloud deployments — Azure, Kubernetes, ArgoCD
