Senior Lifecycle Manager

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.

Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.

01The Role

Synthesia is growing fast, and lifecycle is how we turn that growth into lasting customer relationships, guiding every user from first signup to real value. Every month we send 150+ emails to 1+ million contacts, and as we launch new products and enter new markets, that scale and its impact on revenue will keep rising.

As Senior Lifecycle Manager, you’ll build one of the most exciting lifecycle programmes in Europe. You’ll own the product-led growth motion after signup: the journeys that turn new users into activated, paying and expanding customers. You’ll build automations triggered by what users do in the product and set the standard for how every customer-facing email Synthesia sends works together as one experience. You’ll partner with Product, Product Marketing and Data teams to build a lifecycle engine that grows with the company.

02What You'll Do

• Customer journeys: Design, build and optimise lifecycle journeys that support customers throughout their experience with Synthesia, from activation, adoption and engagement through to expansion, retention and winback.

• Lifecycle automation: Own the end-to-end implementation of lifecycle programmes, from audience segmentation and behavioural triggers to workflow logic, suppression rules, QA and performance monitoring.

• Experimentation: Develop and execute structured experiments to continuously improve lifecycle performance. Test messaging, timing, segmentation and journey design, analyse results and turn learnings into actionable improvements.

• Data-driven personalisation: Leverage product usage, customer attributes and engagement signals to deliver increasingly relevant lifecycle experiences.

• Lifecycle quality and deliverability: Own campaign QA and testing processes, support email deliverability and sender reputation and help establish best practices for segmentation, frequency management and customer experience.

• AI-powered lifecycle: Explore and apply AI to make lifecycle marketing more effective and efficient. From content creation and dynamic personalisation to workflow automation, identify opportunities to improve both the customer experience and how we work.

03We’d love to hear from you if you have

• You deliver impact: You understand how lifecycle marketing contributes to activation, adoption, retention and revenue, and you can demonstrate measurable results from programmes you’ve owned

• You’re analytical and curious: You use data to understand performance, challenge assumptions and continuously improve what you build

• You think in customer journeys: You look beyond individual emails to understand the customer experience, identify friction and create relevant, connected communications

• You’re technically excellent: You’re confident building sophisticated automation, managing complex segmentation and working with customer and product data. You care about the details that make programmes effective and reliable

• You take ownership: You’re comfortable independently leading initiatives from concept through execution, proactively solving problems and making informed decisions

• You collaborate naturally: You know how to work across functions, build strong relationships and move complex projects forward without direct authority

• You care about quality: From deliverability and data accuracy to messaging and customer experience, you hold your work to a high standard

• You’re excited about AI: You actively explore how emerging technologies can improve personalisation, experimentation and the way lifecycle marketing operates

04We’d be particularly excited if

• 6+ years of experience in lifecycle, CRM or email marketing, ideally in B2B SaaS or product-led companies

• Strong hands-on experience with HubSpot, including complex workflows, list building, segmentation and campaign execution

• Proven experience building and optimising always-on automated programmes, including onboarding, nurture and re-engagement, alongside one-off campaigns

• Experience owning lifecycle initiatives end to end, from briefing and journey design to implementation, QA, reporting and optimisation

• Strong analytical skills, with experience using product, CRM and engagement data to build audiences, evaluate performance and run structured experiments

• Practical experience using AI to improve lifecycle execution, operational efficiency or customer personalisation

• Working knowledge of email deliverability, including SPF, DKIM and DMARC, and privacy regulations such as GDPR and CCPA/CPRA

• Proven ability to manage complex cross-functional projects and influence stakeholders across different teams

05Nice to have

• Experience with customer data platforms

• Experience with Salesforce, particularly connecting CRM and account data to lifecycle programmes

• Experience with in-product messaging and multichannel lifecycle journeys

• SQL skills for self-serve behavioural analysis and insights
