Growth & Lifecycle Marketing Manager - B2B SaaS

🎯 Mission

Build and scale Letsignit’s email-driven growth engine.

You will own the full lifecycle email strategy across the funnel — from lead nurturing to install base activation — ensuring every message is triggered by real signals, optimized for performance, and directly connected to pipeline impact.

This is not a newsletter role.

This is not calendar-based email marketing.

This is a

growth-focused, data-driven, signal-based lifecycle role

.

🔎 Why this role exists

As we scale internationally and accelerate our acquisition efforts, email and lifecycle programs have become critical levers for performance.

Today, campaigns exist — but they are not fully systemized, optimized, or monitored with a strong data backbone.

We are looking for someone who will:

• Take ownership of our lifecycle architecture

• Structure and optimize existing flows

• Build & optimized signal-based nurturing programs

• Drive measurable impact on pipeline

💛 Position in the team

You will work closely with:

• CMO & Head of Acquisition

• BDR team

• Sales & RevOps

The Acquisition team generates demand.

The BDR team creates conversations.

You optimize the transitions between both.

🔥 Responsibilities

1. Audit, structure & own the lifecycle system

• Audit current nurturing flows and email sequences

• Map the full funnel lifecycle (MQL → SQL → opportunity → install base)

• Define segmentation logic and trigger architecture

• Implement suppression rules & cadence governance

• Ensure deliverability health and database quality

Deliverable: a structured, documented, scalable lifecycle system.

1. Re-structured & optimized signal-driven nurturing & reactivation programs

Design and manage flows based on:

• High-intent website behaviors

• CRM status changes (no-show, stalled, lost, inactive)

• Content engagement

• Event participation

• SDR interaction signals

• Install base activity patterns

Typical programs include:

• MQL nurturing by persona / industry / territory

• Demo no-show recovery sequences

• Post-event conversion sequences

• Reactivation of dormant leads

• Cross-sell & upsell activation for existing customers

1. Orchestrate Marketing × SDR workflows

• Align marketing automation with SDR cadences

• Define ownership rules (when marketing nurtures vs when sales takes over)

• Build hybrid workflows combining automation + human follow-up

• Optimize speed-to-lead & follow-up logic

Objective: reduce friction and increase meeting conversion.

1. Performance & experimentation

Each flow must have:

• One clear objective

• One primary KPI

You will:

• Run A/B tests (subject lines, CTA, copy, cadence)

• Continuously improve conversion rates

• Analyze pipeline impact of lifecycle programs

• Improve reactivation & meeting booking rates

• Monitor deliverability & list health

We care about:

• MQL → SQL conversion

• Meeting booking rate

• Pipeline influenced

• Reactivation rate

• Deliverability performance

(Not just open & click rates.)

1. Ops, Data & Tooling

You will own:

• Marketing automation workflows

• Segmentation & scoring logic

• CRM hygiene of your work in collaboration with RevOps

• Attribution clarity & UTM governance

• Automation tools (Zapier / Make / n8n / similar)

You think in systems, not isolated emails.

Experience & Environment

• 3–5 years of experience in Growth, Lifecycle, CRM, or Marketing Ops roles within a B2B SaaS environment

• Experience in multi-market or international SaaS environments

• Experience leveraging AI tools for personalization, testing, or automation

• Fluent English (written and spoken)

Technical & Performance Expertise

• Strong hands-on experience with marketing automation and CRM tools (e.g., Marketo, Salesforce, Lemlist or equivalent)

• Proven ability to design, build, and optimize nurturing and outbound flows across the funnel

• Solid experience in A/B testing and campaign performance analysis, using data to optimize engagement and conversion

• Strong conversion-oriented copywriting skills, with the ability to craft the right message at the right moment

Collaboration & Execution

• Demonstrated experience collaborating closely with Sales, SDRs, Acquisition, and RevOps teams

• Highly organized and detail-oriented, able to manage multiple workflows and priorities simultaneously

Mindset

• Data-driven mindset with a strong experimentation culture

• Proactive, accountable team player with a hands-on mindset and strong ownership of results
