Proposition Manager

Propositions Manager (GTM Focused)

📍 City, London | Hybrid (3 days/week in office – Tue & Wed mandatory)

We’re hiring a commercially sharp Propositions Manager to own the end-to-end launch of new and evolving propositions across a large-scale UK telco business.

This role sits at the intersection of product, commercial, and customer experience, taking ideas from concept to launch and post-launch optimisation — with clear, measurable outcomes.

What you’ll be doing:

• Own GTM for new products and major changes across web & app (e.g. eSIM)
• Build and own business cases: revenue, cost, churn, CLTV
• Design and optimise end-to-end customer journeys across the full lifecycle
• Turn customer insight, product vision, and CS feedback into a prioritised GTM backlog
• Partner closely with Product, Tech, Ops, CS, Legal/Compliance, Finance, and Data
• Lead launch planning, governance, UAT, go/no-go, rollout, and hypercare
• Track post-launch performance and iterate based on real commercial impact

What we’re looking for:

• Strong B2C GTM / product-commercial experience (must-have)
• Background in subscription businesses (highly preferred)
• Experience in regulated industries (telecoms ideal; fintech also relevant)
• Commercial mindset with strong analytical skills (Excel, SQL)
• Confident stakeholder manager who can push back and make data-led trade-offs
• Experience working in scale-up environments

Why this role?

• High-impact ownership of GTM in a 3M+ customer B2C business
• Genuine growth hire — scaling GTM capability, not backfilling
• Data-driven, experiment-friendly culture with strong post-launch analytics
• Close collaboration with Product, Commercial, and Operations leadership
