Analytics Lead – Experimentation

Jobtailor; Greater London; On-site; GBP 65,000 - 90,000; Full time

Job summary

Jobtailor is seeking an experienced analytics lead in London to own metric integrity, validate AI-generated outputs, and design robust experiments that translate into commercial action.

You will build dashboards and self-serve tools for stakeholders, explain complex findings to non-technical teams, and drive data-informed decisions across the business.

Qualifications

• Track record diagnosing causes and driving actions that change outcomes.
• Fluency with SQL and data concepts to sense-check AI outputs.
• Experience designing experiments and turning findings into commercial recommendations.
• Ability to explain complex findings to non-technical audiences; experience with Python/Tableau/Looker is a plus.

Responsibilities

• Owning metric integrity — defining and governing what our numbers actually mean, so no one downstream is making a call off a flawed definition or a dodgy query.
• Acting as the quality gate on AI-generated analysis — checking the logic, validating the output, and catching errors before they ever reach a stakeholder.
• Designing and interpreting A/B tests — setting the success metrics, sizing the sample properly, and knowing when a result is underpowered rather than just running with it.
• Diagnosing what's actually driving commercial performance — why revenue is moving, where leads are dropping out of the funnel, which segments are underperforming — and turning that into a structured investigation with real hypotheses.
• Turning analysis into action — sizing the commercial impact, laying out the trade-offs, and helping the business decide what to do differently, then tracking whether it worked.
• Building interactive dashboards and self-serve tools that keep stakeholders oriented day-to-day, without an analyst needing to be in the loop every time.

Job description

• Owning metric integrity — defining and governing what our numbers actually mean, so no one downstream is making a call off a flawed definition or a dodgy query.
• Acting as the quality gate on AI-generated analysis — checking the logic, validating the output, and catching errors before they ever reach a stakeholder.
• Designing and interpreting A/B tests — setting the success metrics, sizing the sample properly, and knowing when a result is underpowered rather than just running with it.
• Diagnosing what's actually driving commercial performance — why revenue is moving, where leads are dropping out of the funnel, which segments are underperforming — and turning that into a structured investigation with real hypotheses.
• Turning analysis into action — sizing the commercial impact, laying out the trade-offs, and helping the business decide what to do differently, then tracking whether it worked.
• Building interactive dashboards and self-serve tools that keep stakeholders oriented day-to-day, without an analyst needing to be in the loop every time.

Requirements

• A track record across all three layers — not just producing analysis, but diagnosing the cause and driving the action that actually changed the outcome.
• The analytical foundation to sense-check AI-generated work — fluency with SQL and data concepts, so you know when an output is wrong before anyone else spots it.
• Experience designing experiments and turning statistical findings into commercial recommendations that hold up under scrutiny.
• A knack for explaining complex findings to non-technical audiences in a way that actually moves a decision — experience in a marketplace, subscription or lead-generation business, or with tools like Python, Tableau or Looker, is a bonus rather than a must.

Core Competencies

Demonstrates expertise in metric integrity, A/B testing design, and translating complex data analysis into actionable business strategies. Proficient in SQL and experienced in building interactive dashboards to enhance stakeholder engagement.
