Senior Growth Marketing Manager in London

This is a high-impact, high-autonomy role at the centre of one of the most important bets in the business. AI Operator is the agent layer across the Threecolts ecosystem, enabling sellers to run their business through natural language using live operational and financial data. It has the potential to fundamentally change how our customers interact with our products — and your role is to drive that adoption at scale.

You will take full ownership of growth for AI Operator, with the freedom to test, build, and scale what works. This is not a role where you inherit a fixed playbook. You will define it. From lifecycle, content, and partnerships, you will decide where to focus, move quickly, and double down on what delivers results. You will operate across the full funnel, from first touch through to paid conversion, with a clear mandate to turn AI Operator into a meaningful revenue driver. The expectation is pace, ownership, and impact — building repeatable growth systems that scale, rather than running isolated campaigns.

You are expected to operate in an AI-first way, using tools like Claude to significantly increase speed, output, and experimentation across campaigns, content, and lifecycle. This is a core part of how the role delivers impact. This is a role for someone who wants to move fast, take ownership, and have a visible impact on the trajectory of a new product.

What you’ll do:

• You will take full ownership of growth for AI Operator across key channels and stages of the funnel.
• You will also build and run the email lifecycle, including onboarding flows that drive first value, activation sequences that encourage regular usage, and retention and upsell journeys that convert users from free to paid tiers.
• A core part of the role is building PLG growth loops. You will analyse how users discover, adopt, and extract value from AI Operator, then design and iterate on mechanisms that improve conversion at each stage.
• You will work closely with our influencer marketing and agency teams to activate AI Operator across both channels.
• You will partner with our Customer Interactions team to produce high-volume, high-performing content, including short-form and viral formats with the focus being on output and performance.
• You are expected to identify repeatable growth plays and build scalable systems that can be run and optimised continuously.
• You will work closely with product, engineering, and data teams to ensure growth activity is aligned with how the product is evolving, and grounded in real user behaviour and performance data.

Core competency:

• Market domination mindset, focused on scaling aggressively rather than optimising at the margins.
• Strong bias for action, with the ability to move quickly from idea to execution.
• End-to-end ownership across channels, without relying on others to fill gaps.
• Ability to translate product capability into clear drivers of adoption and growth.
• High comfort operating in ambiguous, fast-moving environments.

What we’re looking for:

• A senior growth marketer who can operate as a high-output generalist across multiple channels, with a strong track record of scaling products in PLG or performance-driven environments.
• Deep, hands-on experience owning lifecycle marketing end-to-end, with a clear understanding of how to drive efficient growth through social, email, and content.
• Comfort managing the full funnel and understanding how acquisition, activation, and retention link together commercially.
• Highly effective in using AI tools, including Claude, to increase speed, output, and quality of execution across campaigns, content, and experimentation.
• Strong commercial mindset, with a clear grasp of CAC, LTV, and conversion dynamics, using data to make decisions rather than relying on intuition alone.
• Execution-focused, testing quickly, learning from results, and iterating at pace.
• Experienced working with influencers, agencies, or partner channels, turning these into scalable acquisition drivers.
• A hands-on builder, creating, executing, and optimising yourself.
• Comfortable operating with pace and pressure, motivated by owning outcomes rather than contributing to a small part of the process.
