Social Media Manager

Most financial companies treat social media as a broadcast channel, a place to announce features, celebrate milestones, and fill a content calendar.

At Mercury, we see it differently.

Social media is where we connect with our community. It is where credibility is earned in real time, where cultural fluency signals relevance, and where builders decide whether a company understands the world they operate in, or not.

We are building a brand that founders respect, operators trust, and the internet recognizes as thoughtful, precise, and culturally aware. Social plays a critical role in that ambition.

We are looking for a Social Media Manager to shape Mercury’s voice within the tech and founder ecosystem. This person will build platform-native strategies, identify meaningful cultural moments to participate in, and serve as the internal authority on what belongs online.

This role sits within the Community team and works at the intersection of brand, product, customer experience, and growth. You will lead Mercury’s presence on X and Reddit while partnering closely with the Community Manager overseeing LinkedIn and Instagram. You will guide participation across channels and help ensure that some of Mercury’s most visible public surfaces reflect the company’s rigor, taste, and intelligence.

What you’ll do:

Build and own Mercury’s social strategy

• Develop platform-native strategies for X and Reddit as Mercury’s primary real-time channels
• Define Mercury’s participation model: when to speak, where to engage, and how to build credibility over time
• Maintain broad fluency across the evolving social platform landscape (LinkedIn, IG)  to guide strategy and ensure Mercury shows up appropriately across channels
• Ensure Mercury shows up with clarity, restraint, and conviction

Lead integrated campaign and launch rollouts

• Translate marketing campaigns and product launches into platform-native social strategies
• Partner with Brand, Product Marketing, Comms, CX, and Community to ensure cohesive storytelling
• Build rollout frameworks connecting social to editorial, partnerships, and IRL activations
• Identify opportunities to extend campaigns into meaningful conversation

Serve as Mercury’s cultural radar

• Monitor cultural discourse, internet behavior, and platform-native trends
• Track moments relevant to founders, operators, and builders
• Identify opportunities for Mercury to participate with relevance and credibility
• Advise leadership on real-time participation and reputational risk

Establish Mercury’s voice in the tech & founder ecosystem

• Maintain a deep understanding of the startup, venture, fintech, and AI landscape
• Track conversations and sentiment across hubs including San Francisco, New York City, Los Angeles, and Austin
• Engage in discussions with founders, operators, and investors
• Ensure Mercury’s voice resonates with ambitious builders

Lead CX–Social coordination

• Partner with Customer Experience to create seamless social response workflows
• Monitor sentiment, questions, and friction surfaced via social channels
• Ensure insights inform product, CX, and messaging improvements

Provide governance and internal guidance

• Act as the internal voice of reason for social participation
• Establish best practices for social engagement across teams
• Build playbooks for launches, announcements, and reactive moments
• Protect long-term brand equity while enabling timely participation

Measure what matters

• Define success metrics beyond vanity engagement
• Track sentiment, relevance, and share of voice in founder conversations
• Continuously refine strategy based on performance and cultural shifts

What success looks like

• Mercury is recognized as a credible, intelligent voice in founder and tech c
