Senior Python Software Engineer

Senior Python Software Engineer Bristol | Up to £75,000 + Stock Options | Hybrid – 3 days onsite Most Python roles lead with the framework. This one starts with Linux. I’m working with a growing B2B SaaS company in Bristol that is building a genuinely differentiated behavioural-science and media-planning platform. They are hiring a Senior Python Software Engineer who can take ownership across the full technical lifecycle: shaping a solution, building it, deploying it and supporting it in production. This is not a narrow ticket-delivery role. You will have real influence over the architecture, engineering standards and future direction of the platform. What you’ll be working on Designing and building Python backend applications and APIsDeveloping services using FastAPISupporting and troubleshooting Linux-based environmentsBuilding data-processing, automation and ingestion workflowsDesigning and maintaining SQL and NoSQL databasesDeploying containerised services across AWSImproving testing, security, documentation and production reliabilityHelping shape the engineering function as the company grows What they’re looking for You will need strong commercial Python software-engineering experience across backend systems, APIs, automation or data processing. Just as importantly, you must be genuinely comfortable working with Linux. That means more than deploying a Docker container.
