Experimentation Lead

**What’s the role about?**

Are you a champion of experimentation?

As our Experimentation Lead, you will be leading the “Centre of Excellence” function for our high-volume (1000+/year) experimentation programme during a time of exceptional growth. You will be responsible for all aspects of Experimentation within John Lewis including Programme Governance, Education, Automation, Measurement and Skills Development across dozens of agile product experimentation teams. Your primary focus will not be on individual experiments but on making the flywheel of experimentation spin faster in these teams, removing human cost and friction from testing and increasing the business value and quality of experimentation.

The remit of your team is to collect and report data on experimentation and data quality, as well as managing or providing automation, tooling, education, onboarding, pairing, peer-review and skills development across experimentation teams. You will get to build both an Analytical Function (Education, Programme Measurement, Analysis) as well as a Product Function (workflow, process automation and tooling for product teams) to support a network of ambassadors embedded within product teams.

In this role, you will grow your own team of data engineers, developers, data scientists, and educators alongside the ambassador network, to scale the volume and quality of decisions made through testing. As well as supporting education and skills, we’d like you to iterate and improve the culture of experimentation within The Partnership - building a vibrant and supportive internal experimentation community as well as establishing links with peers and experts outside the organisation.

This is an excellent opportunity for someone to be able to influence and design the scaling of our experimentation programme, helping grow your personal and professional skills as well as links with the experimentation community. Come and make your mark in the domain of experimentation by building a world-class centre-of-excellence team and taking an already successful programme to new heights.

**What will you be doing?**

You will develop the long-term strategy for Experimentation within John Lewis by building a centre-of-excellence and ambassador programme to provide the following functions: Automation, Tooling, Education, Onboarding, Pairing, Peer-Review and Skills Development for Experimentation Teams as well as growing our internal culture and connections with the wider experimentation community.

Support a multidisciplinary network of teams running experiments, by having a shared objective to continually evolve the maturity of experimentation within John Lewis. Your role is to design and lead the expertise, education, documentation, organisational frameworks and data products that scale our experimentation capabilities in an efficient and automated way.

You’ll be responsible for all aspects of driving the implementation of the structure, process, people, resources, organisational design and metrics that will be required to govern our experimentation programme effectively.

To make the flywheel of experimentation spin faster for all the teams running tests. You’ll achieve this by decreasing human time, cost and friction in running experiments as well as governing the measurement and improvement in value of the results.

Your team will be delivering standardised tools, methods, approaches, documentation and experiment designs to automate repetitive tasks as well as facilitating the sharing of results, pairing, peer review and experiment scorecards. The centre-of-excellence is there to monitor, measure, support and guide the quality and reliability of experiments being executed by product teams.

Your team will also drive the development of the experimentation process and analytical frameworks. This will include collecting, documenting, teaching and sharing best practices as well as building the necessary data products and tooling to support the ambassadors and teams through automation.

Design and implement a governance framework to measure the quality and value of experimentation (scorecards, metrics, targets, peer review, business value) across teams, so you can provide measurement around the efficacy of the experimentation programme or know which teams you need to provide with additional support. The approach is that “we all want to help each other get much better at running experiments”.

You’ll build our internal community through the ambassador programme but also with internal events, drop-in sessions, knowledge repositories, communications, driving curiosity, interest and awareness across the wider business. We expect you also to drive awareness and understanding of the strategic role of experimentation in making reliable business decisions, so Leadership awareness and skills are important here too.

We want you to be active in external networks, communities and events to build links with the external experime
