Lifecycle Marketing Manager - Remote US

The Opportunity

Seamless is looking for a Lifecycle Marketing Manager to own the journeys, systems, and automation that turn interest into pipeline, and pipeline into revenue.

This role is for the hands-on marketer who has spent years thinking about what happens after someone raises their hand. You know that great marketing does not stop at acquisition. It continues through onboarding, activation, engagement, expansion, and retention.

You’ll sit at the intersection of Marketing, Product, Sales, Customer Success, and Revenue Operations, building the infrastructure that makes every touchpoint feel timely, relevant, and connected to revenue.

If you’ve ever looked at a nurture sequence, onboarding flow, or lead scoring model and thought, “I can make this better,” this role was written for you.

Your Team

You’ll partner closely with Demand Generation, Product Marketing, Revenue Operations, Sales, Product, and Customer Success.

These teams are not looking for someone to simply “send emails.” They need a lifecycle marketer who can connect the dots across the funnel, understand the customer journey, and build the systems that help the right users take the right actions at the right time.

You’ll be the owner of the automation layer that helps Seamless scale smarter.

What Winning Looks Like

Sharper Journeys, Better Outcomes: You’ve improved the way prospects, free users, trials, and customers move through the funnel. The experience feels more relevant, more personalized, and more connected to their goals.

Cleaner Sales Handoffs: You’ve tightened segmentation, lead scoring, triggers, and routing logic so Sales gets higher-quality, better-timed opportunities.

Faster Activation: You’ve improved onboarding and product engagement by building lifecycle programs that reduce time-to-value and guide users toward meaningful actions.

A Scalable Automation System: You’ve moved beyond one-off campaigns. You’re building documented workflows, repeatable playbooks, and AI first automations that can grow with the business.

Data-Driven Optimization: You’re testing subject lines, messaging, timing, CTAs, segmentation, and journey logic, then using the results to improve performance across the funnel.

What You’ll Own

The Lifecycle Engine: You’ll design, build, and optimize multi-channel programs across cold and warm email, in-app messaging, SMS, and automation platforms. From first touch to expansion, you’ll own the journey.

Nurture & Conversion Programs: You’ll create nurture sequences for key audiences, including free users, trials, prospects, customers, and expansion opportunities. You’ll build programs that move people meaningfully through the funnel.

The Automation Infrastructure: You’ll manage the “brain” of our lifecycle motion, including Customer.io, Claude, N8N and drive segmentation, behavioral triggers, lead scoring, campaign logic, and workflow documentation.

Segmentation & Personalization: You’ll develop audience frameworks that help us deliver more relevant messaging based on persona, use case, funnel stage, product behavior, and firmographic data.

Product-Led Growth Support: You’ll partner with Product and Growth to build lifecycle campaigns tied to onboarding, activation, feature adoption, product usage milestones, and self-serve conversion.

Reporting & Experimentation: You’ll own lifecycle performance reporting across engagement, conversion, activation, MQL velocity, retention, expansion, and pipeline influence. You’ll test constantly and turn insights into playbooks.

Who You Are

A B2B SaaS Lifecycle Marketer: You have 3+ years of experience in lifecycle marketing, CRM marketing, growth marketing, or marketing automation, ideally in B2B SaaS.

Hands-On With Automation: You’ve built campaigns yourself in tools like Customer.io, Claude, N8N, HubSpot, Marketo, Braze, Iterable, or similar platforms. You do not just write briefs. You build the workflows.

Customer Journey Obsessed: You think in segments, stages, triggers, and next best actions. You care about getting the right message to the right person at the right time.

Sales-Aligned: You understand that lifecycle marketing should support pipeline, conversion, retention, and revenue. You know how to partner with Sales and RevOps to improve handoffs and lead quality.

Technical & Analytical: Tools like Salesforce, Segment, Amplitude, and Customer.io are part of how you think. You’re comfortable using data to diagnose problems and improve performance.

A Strong Communicator: You can write a compelling subject line, a clear nurture email, and a tight product education message. You can also explain performance insights to Marketing, Sales, Product, and leadership.

A Self-Directed Operator: You document your work, manage competing priorities, and build systems that outlast a single campaign.

Skillset

Experience: 3+ years in lifecycle marketing, CRM marketing, growth marketing, demand generation, or marketing automation within B2B SaaS or a high-growth technology environment.

The Stack: Hands-on experience with marketing automation tools like Customer.io, HubSpot, Marketo, Braze, N8N, Claude, Codex or Iterable. Familiarity with Salesforce, Segment, Amplitude, and landing page tools is strongly preferred.

The Playbook: You have built automated journeys, nurture programs, onboarding flows, segmentation frameworks, lead scoring models, behavioral triggers, and testing programs.

Analytics: You understand lifecycle and funnel metrics, including activation, engagement, conversion, retention, expansion, churn, MQL velocity, and pipeline influence.

Communication: You can translate lifecycle performance into clear recommendations for Marketing, Product, Sales, Revenue Operations, and leadership.

Bias for Action: You would rather test, learn, and iterate than spend weeks building the perfect campaign in theory.

Education & Requirements

Background: A Bachelor’s degree or equivalent real-world experience in a B2B SaaS GTM, lifecycle, growth, or marketing automation role.

Execution: Demonstrated ability to build, launch, optimize, and report on automated programs from strategy through execution.

Product Curiosity: You enjoy figuring out how tools like Customer.io, Segment, Amplitude, Salesforce, Unbounce, and Seamless can work together to create better customer journeys and cleaner data.

The Extras: Experience with product-led growth, freemium motions, self-serve conversion, product-triggered campaigns, sales technology, revenue technology, or RevOps ecosystems is a plus.
