Job description

Flex is a growth-stage, NYC headquartered FinTech company that is creating the best rent payment experience. It’s hard to believe that it’s 2026 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! Flex enables our users to pay rent throughout the month on a schedule that better fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense. After deliberately keeping a stealth profile as we built up unprecedented investor support and an enthusiastic user base, we are looking for motivated individuals to help us keep our mission growing. Will you be a part of the team?

Job Description

We are seeking an experienced Manager, Lifecycle Marketing to join our dynamic team. This individual will play a critical role in developing, optimizing, and executing lifecycle marketing email and SMS campaigns to engage and convert customers. The ideal candidate will have a strong background in email marketing, A/B testing, retargeting, and customer communication strategies. This person will be working closely with cross-functional teams to craft impactful customer communications that increase acquisition, retention, and reactivation efforts.

Key Responsibilities

• Email & SMS Campaigns: Manage the campaign lifecycle from concept through implementation, monitoring, and optimization. Design, build, and implement both marketing email and SMS campaigns with a focus on driving engagement and sign ups.
• Creative & Content Development: Develop compelling, high-converting email and SMS creatives. Ensure messaging aligns with brand voice, resonates with target audiences, and is optimized for engagement across different segments. Continuously test and refine content based on performance insights.
• A/B Testing, Optimization & Customer Segmentation: Lead the execution of A/B testing initiatives to continuously improve email and SMS performance (open rates, CTR, conversions) and ensure the highest level of customer engagement. Leverage data to segment audiences for personalized messaging. Develop strategies for customers based on historical behavior, lifecycle stages, and product interaction.
• Collaboration & Cross-Functional Engagement: Collaborate with internal teams (creative, content, sales, etc.) to ensure marketing campaigns are well-supported and executed efficiently. Align messaging with company goals, ensure consistency, and deliver a seamless user experience across all communication channels.
• Innovation & Strategy: Lead the planning, coordination, and execution of marketing campaigns, ensuring alignment with overall business goals and objectives. Bring fresh, creative ideas to the table for optimizing customer communication. Use data-driven insights and industry trends to craft innovative email/SMS marketing strategies that improve customer engagement and app traffic.
• Escalation Management: Oversee escalation processes for any issues that arise during the campaign, ensuring smooth execution and timely resolution. Coordinate feedback loops, ensuring any adjustments needed during the campaign process are swiftly addressed.
• Reporting & Analysis: Track and analyze campaign performance. Report on campaign performance, providing insights and actionable recommendations for continuous improvement. Use analytical tools to evaluate campaign success and track key metrics like conversion rates, ROI, and customer engagement.
• Regulatory Compliance: Stay up-to-date with federal regulations and ensure all marketing and transactional communications adhere to relevant legal and industry guidelines (e.g., TCPA, GDPR, CAN-SPAM).

Preferred Qualifications

• 5+ years of experience in lifecycle marketing email and SMS campaign management, with a focus on A/B testing and customer communication optimization.
• Proficiency with email and SMS marketing platforms (Braze preferred), A/B testing tools, and analytics software. Comfort with segmentation logic and campaign QA
• Strong ability to analyze data and translate insights into actionable strategies for improving marketing performance and customer engagement.
• Experience with building AI-assisted approaches for repeatable work (segmentation, QA, drafts, analysis), with sound judgment on when to rely on AI output versus apply closer human review
• Proven track record in driving acquisition, retention, and reactivation through targeted messaging and segmentation.
• Highly collaborative, with the ability to work cross-functionally with marketing, product, data, and compliance teams. Demonstrated ability to influence cross-functional stakeholders.
• Creative, innovative thinker with a passion for optimizing user experience through digital communication channels.
