We are introducing a number of Senior Product Engineers to build the future B2B platform at Which?. You will be instrumental in creating a new greenfield full-stack, cloud-native platform in AWS to support new business offerings.

We are seeking experienced engineers with a background in scaled and established organizations. Ideal candidates will possess expertise in greenfield development, constructing end-to-end user experiences, and implementing new production workflows. Additionally, experience with integrating 3rd party APIs, including public API integrations, event-driven, and asynchronous flows is required.

• Software Development and Technical Direction
  :
  Writing software and tests, software design, and working on quality aspects like performance, security, and fault tolerance. This will focus on the new B2B platform's core services, APIs, and end-to-end user experience. You will own the release process and champion innovative use of cloud-native AWS technology. You will engage in technical discussions to guide decisions on the greenfield architecture.
• Collaboration
  :
  Working with your squad and stakeholders to set up and plan quarterly OKRs that drive the success of the new B2B offering. You will ensure your Squad's work on the B2B platform is aligned with the wider strategy and commitments.
• Operational Excellence
  :
  Setting high standards and driving engineering best practice across the new B2B stack. This includes focusing on observability (monitoring, logging, tracing) for the cloud-native solution, participating in peer reviews, and facilitating the maintenance of engineering standards, reliability, and performance.
• Squad Empowerment
  :
  Contributing to a culture of creativity, curiosity, collaboration, inclusion and innovation within your Squads as you adopt new technologies and practices for the greenfield project.
• Championing “You Build It, You Run It”:

You will apply your expertise to build the new B2B platform and create new flows from scratch.
• AI-Native Engineering
  :
  You will champion the use of agentic workflows to accelerate delivery across the B2B platform. As an AI-fluent leader, you will leverage Git Hub Copilot as a primary partner to automate testing, streamline implementation, and minimize cognitive overhead, ensuring your focus remains on solving our most complex architectural and product puzzles.
• End-to-End Use Case Ownership
  :
  You will take full ownership of the end-to-end use cases for the new B2B platform. This includes designing, implementing, and taking responsibility for the AWS infrastructure, deployment, and observability across the new stack.
• External Integrations Expertise
