Marketing Operations Manager in City of London

Sweep is hiring a Marketing Operations Manager to own our core marketing processes, with a focus on lead lifecycle governance (especially MQL/SQL consistency), marketing data management (collection, enrichment, hygiene), and the marketing-to-SDR handoff and SLA implementation across multiple go-to-market motions. You will sit within the marketing team, working closely with the VP of Marketing, and will be managed by the Director of Demand Generation. This role is essential for cross-functional analysis and will collaborate frequently with RevOps, SDR leadership, Marketing leadership, and Field Marketing.

This role sits at the center of Demand Gen, RevOps, SDR leadership, and the broader marketing team. You will ensure that our systems and processes produce clean data, consistent lifecycle outcomes, and clear accountability. This is a hands-on builder role for someone who blends systems thinking with operational rigor and strong cross-functional influence. You will act as a strategic advisor, leveraging data to influence go-to-market decisions and accelerate the company’s revenue goals—bringing an informed point of view on the tech stack needed to make it happen.

To be more specific, this includes:

• Lifecycle Governance and Process Ownership: Own and standardize lead lifecycle definitions, with a focus on making definitions operationally enforceable. Partner with Demand Gen, RevOps, and SDR leadership to align lifecycle stages to real workflows across multiple motion types (inbound, field), including stage entry/exit criteria and routing logic. Maintain governance for lifecycle changes, including documentation, change management, and adoption.
• Marketing-to-SDR Handoff, SLAs, and Compliance: Own the end-to-end handoff from Marketing to SDR for post-MQL first touch (with SDR as the first owner), ensuring it is measurable and scalable. Implement and maintain SLAs, including a 12-hour speed-to-lead SLA, with accurate alerting when SLAs are breached. Build and maintain the operational agreement between Marketing and SDRs, including routing rules, recycling logic (where applicable), required context for follow-up, and exceptions by motion type.
• Marketing Data Management (Collection, Enrichment, Hygiene): Own data quality and governance that supports lead profiling and engagement, including field standards, validation, normalization, and hygiene. Ensure consistent data capture across touchpoints and improve data completeness without adding unnecessary friction. Partner with RevOps on HubSpot-to-Salesforce data flow, including field mapping, sync behavior, lifecycle timestamps, and source-of-truth decisions.
• Systems, Standards, and Reporting: Own the HubSpot ops foundation (properties, workflows, segmentation logic, automation standards), with an emphasis on scalability and auditability. Coordinate with web and digital resources on website forms, conversion tracking requirements, and QA. Serve as an analytical engine for marketing: proactively dive into funnel performance data (Metabase/HubSpot/Salesforce) to identify trends and untapped conversion optimization opportunities.

At Sweep, artificial intelligence is part of how we work, learn, and build. Every team member uses AI tools daily to speed up operations, improve decision making, and unlock creativity. We don’t expect you to be an expert on day one, but we do expect curiosity, a willingness to experiment, and the desire to use AI as a true partner in your work. Whether it’s analyzing information, drafting content, improving workflows, designing better employee experiences, or supporting distributed teams, you’ll use AI to work faster and smarter. We provide guidance, tools, and best practices so you can get the most out of it. We’re looking for candidates who already have hands-on experience with AI tools in a professional setting.

This is who we’re looking for:

• Qualifications: You bring a minimum of 4 to 8 years of experience in Marketing Operations or Revenue Operations roles in B2B (SaaS preferred), with direct ownership of lifecycle processes and cross-functional rollout. Strong hands-on expertise in HubSpot Marketing Hub Enterprise (required), ideally including Data Hub and advanced workflow and data architecture. Proven experience defining and operationalizing MQL/SQL and lifecycle governance in a real GTM environment. Experience implementing marketing-to-SDR handoffs, SLA monitoring, and breach alerting. Working knowledge of Salesforce integrations and practical data sync concepts (mapping, ownership models, timestamps). Analytical and process-driven, able to identify root causes in funnel performance and implement durable fixes. Strong communication and stakeholder management skills.
• Qualities: A hands-on problem solver, self-motivated with a glass half-full attitude. An entrepreneurial mind, ready to launch and fail and iterate. You’re an empathetic team player that is great at building lasting relationships. Attuned to remote collaboration, using digital tools and meticulously documenting work. A strong desire to evolve on the SaaS & Tech environment.
