Senior Manager, Lifecycle & Buyer Growth Marketing

JOB SUMMARY

B-Stock's marketplace growth depends on a thriving buyer ecosystem at every level. This role owns the full buyer lifecycle — from acquiring and activating new buyers to growing them into Key Buyers ($25K+ GMV/quarter) and Premium Buyers ($250K+/year) — through personalized lifecycle marketing, data-driven programs, and cross-functional execution.

This role exists to make hard calls, not just run campaigns. B-Stock has dozens of seller requests, marketing campaigns, and product updates competing for buyer attention every day. Deciding what gets sent, to whom, and what gets cut — and standing behind that decision when a seller or stakeholder pushes back — is the actual job. This person will define which buyer signals matter, place real bets on which channels and segments deserve investment, and own the tradeoffs of that strategy in front of leadership.

This is also a relationship-driven role. Success depends on this person's ability to influence Sellers, BAMs, and cross-functional partners to change how they operate — not just analyze what they should do. For our highest-value segment — Premium Buyers — you will partner with the Buyer Account Management (BAM) team, building enough trust and credibility that they act on your recommendations.

BUYER SEGMENT OWNERSHIP

This role owns the full Buyer funnel:

• All Buyers — Acquire and activate new buyers to their first bid and first win
• Key Buyers ($25K+ GMV/quarter) — Grow and retain; the core of B-Stock's GMV
• Premium Buyers ($250K+/year) — Support the BAM team with marketing programs that deepen engagement and accelerate growth
  
  
  

ESSENTIAL JOB DUTIES AND RESPONSIBILITIES

Strategic Accountability — Own the Tradeoffs:

• Decide what B-Stock's personalization strategy optimizes for — and what it deliberately sacrifices — when buyer relevance, seller demands, and business priorities conflict
• Set the data inputs and prioritization logic for the personalization model, and be accountable to leadership when those choices succeed or fail
• Determine when an underperforming program should be killed, redesigned, or given more time — calls with no clean data answer
• Present the strategy, results, and reasoning behind key decisions directly to leadership, including when results fall short

High-Stakes Judgment Calls:

• Decide which buyer behavior and transaction signals actually predict engagement and lifecycle progression — and which are noise, based on judgment the data alone won't resolve
• Choose which new acquisition channels are worth the investment and risk (e.g., trade shows, ABM, new partnerships) before performance data exists to justify the bet
• Determine when a buyer or seller issue requires personal escalation and judgment versus when it can run through automated systems
• Resolve conflicting priorities across Marketing, Product, BAM, and Sellers when there is no objectively correct answer — only a defensible one

Organizational Influence:

• Influence Sellers — who do not report to you — to change how they message, price, and prioritize for Key and Premium Buyers, using credibility and relationship-building rather than authority
• Build enough trust with the BAM team that they act on your recommendations for Premium Buyer engagement, even when it means changing how they operate
• Win buy-in from Marketing Ops, Data, and Product to prioritize the technical work your personalization strategy depends on — competing against their other priorities
• Represent the buyer's interest in rooms where buyer experience is not the only — or even the primary — priority

Lifecycle Marketing & Demand Generation:

• Own the end-to-end buyer lifecycle — from registration through first bid, first win, Key Buyer status, and long-term retention
• Design and manage multi-channel demand generation programs to acquire new buyers and activate them on the platform
• Build nurture programs that move buyers up the value ladder — from first-time buyers to Key Buyers to Premium Buyers

Measurement & Insights:

• Own dashboards tracking the full buyer funnel: registration-to-bid conversion, activation rates, Key Buyer conversion, GMV contribution, and channel ROI
• Interpret ambiguous or conflicting data to make a recommendation — not just report what the numbers say
• Serve as the internal voice of the buyer — surfacing insights and opportunities across all segments

MINIMUM QUALIFICATIONS, JOB SKILLS, AND ABILITIES

• 5+ years of experience in lifecycle marketing, demand generation, or growth marketing, ideally in a B2B marketplace or e-commerce environment
• Track record of making and defending high-stakes marketing decisions with incomplete data — and owning the outcome
• Demonstrated ability to influence stakeholders who do not report to you, including external partners or sellers, to change their behavior
• Experience designing personalized marketing programs driven by buyer behavior, segmentation, or lifecycle stage — not just executing campaigns
• Strong analytical skills — comfortable defining success metrics and using data to make a judgment call, not just to report results
• Hands-on experience with marketing automation platforms at a workflow design level — Braze, Iterable, HubSpot, Marketo, or similar
• Experience with AI-powered marketing tools for personalization, segmentation, or predictive analytics — and judgment about where AI should and shouldn't drive decisions
• Comfortable presenting strategy and tradeoffs to senior leadership, including defending decisions that didn't work

PREFERRED QUALIFICATIONS

• Experience marketing to professional resellers, wholesale buyers, or B2B procurement audiences
• Familiarity with auction-based or reverse-logistics marketplace models
• Prior experience managing tiered customer programs — different marketing motions for different value segments simultaneously
• Experience building a personalization or next-best-action system from scratch, including data model, scoring logic, and feedback loop
• Experience with marketing ops infrastructure — attribution models, lead scoring, lifecycle triggers, or CRM workflows

The pay rate for this role will range between $130,000 to $145,000, per annum. We consider many factors when determining salary offers, such as the applicant’s work experience, education and training, skills, market data, and internal equity.
