The Platform team builds and evolves the platform used by our panel and research teams. As Senior Software Engineer, Python you will build and evolve high-value products and services that operate at significant scale. the Senior Software Engineer, Python will work with product, design and engineering colleagues to solve complex problems, make sound architectural decisions and deliver reliable software to production. This is a senior individual contributor role with no direct reports: you will work autonomously on complex and ambiguous problems, guide more junior engineers and contribute to engineering practices across the wider engineering organisation . Seniority here is about scope, ownership and impact, We expect our engineers to be AI-native in the way they work, using coding assistants and development agents across their daily workflow, while remaining accountable for the quality, security, correctness and maintainability of everything they put into production.

You Will:

• Design, build and maintain , robust and maintainable Python services and applications that serve high volumes of production traffic.

• Own your software throughout its lifecycle, from design and development through deployment and operation, using self-service CI/CD, infrastructure, monitoring and observability.

• Deliver your part of the team’s roadmap to the agreed quality and timescales and meet the reliability and performance standards for the services you own.

• Build comprehensive automated tests to ensure changes are safe to release.

• Take part in code reviews and architectural discussions and make sound technical decisions on complex and ambiguous problems.

• Identify and address technical debt, reliability risks and opportunities for simplification to keep the platform healthy.

• Take part in incident response and improve system reliability so incidents are rare and recovery is quick

• Guide and review the work of more junior engineers, supporting their technical development.

• Advise and influence colleagues and stakeholders on technical approaches and trade-offs.

• Use AI coding assistants and development agents for design, implementation, testing, debugging and documentation, and critically review all AI-generated output for correctness, security, performance and maintainability.

• Share effective AI-enabled development practices and propose improvements to engineering practices and developer experience

• Work closely with product, design, data and engineering colleagues, and with the teams who use the platform, to deliver customer and business value.

You Have:

Technical skills and knowledge

• Strong professional experience building and operating production software.

• Advanced knowledge of Python

• A sound understanding of software design, testing and engineering best practices, with experience of Git and CI/CD pipelines.

• Experience building and operating services in a distributed or microservices environment.

• Experience with relational and/or document databases such as PostgreSQL and MongoDB.

• Experience with Docker and containerised applications.

• An understanding of production operations, observability, reliability and performance.

• Hands-on experience using AI coding assistants and/or development agents in day-to-day software development.

• Take ownership and accountability for the quality, security and maintainability of the software you put into production.

• Communicate clearly, in writing and verbally, and adapt your message to technical and non-technical colleagues.

• Collaborate with colleagues across product, design, data and engineering, and share what you learn.

• Keep up with change and continuously improve how we build software, including AI-enabled techniques.

What we are ideally looking for

• Experience with Kubernetes and AWS, and with Terraform or other infrastructure-as-code technologies.

• Experience with event-driven systems and messaging.

• Experience integrating LLMs or AI capabilities into production software, or building AI-powered applications and agentic workflows.

• Experience working in a globally distributed and remote environment.

• Experience contributing to open-source projects.
