Senior Backend Engineer (Python)

Backend Engineer (Python/FastAPI) - AI-Native Product Engineering £90,000 - £100,000 Hybrid (London/Remote) If you're the kind of engineer who reaches for AI tooling as naturally as your IDE, enjoys solving real product problems, and prefers building new systems over maintaining legacy code, this could be the role for you. We're working with a well-funded, rapidly scaling property technology business that's transforming a traditionally fragmented industry through AI, automation and modern software engineering. Following significant investment and strategic acquisitions, they're building the technology platform that will power the next stage of their growth. This is an opportunity to join an engineering team where speed, ownership and modern development practices are encouraged, not constrained by process. What you'll be building As a Backend Engineer, you'll help design and develop the APIs and services that power a rapidly growing platform. Working closely with product managers, designers and fellow engineers, you'll ship features quickly, influence technical decisions and help shape how engineering is done as the business scales. This is a genuinely AI native engineering environment. AI assisted development isn't an experiment, it's embedded into the team's workflow, enabling engineers to focus more on solving complex problems and delivering customer value. What you'll be doing Design, build and scale backend services using Python and FastAPIDevelop reliable, well-tested APIs and distributed services running on AWSWork in short, iterative delivery cycles alongside Product and DesignUse AI assisted and agentic development tools (such as Cursor, Claude and similar technologies) to accelerate development and improve code qualityInfluence architecture, engineering standards and platform evolutionCollaborate closely with frontend engineers building modern React applicationsHelp shape engineering practices within a high growth technology businessWhat we're looking for Strong commercial experience building backend applications with PythonCommercial experience with FastAPI (essential)Experience building and operating cloud-native applications on AWSBackground in product-led startups, scaleups or other fast paced engineering environmentsComfortable using AI assisted development tools as part of your everyday workflowAble to work autonomously, make technical decisions and take ownership of deliveryA product mindset with a focus on building solutions that create customer value Why this role? This isn't a company asking whether AI might be useful, they're already building with it. You'll be joining an ambitious engineering team with the freedom to move quickly, influence technical direction and work on meaningful product challenges rather than spending your time maintaining legacy systems. If you've enjoyed working in high growth environments, embrace modern AI enabled development, and want to help build a platform with genuine scale and impact, we'd love to hear from you.
