Job description

Who We Are?

Over the next few years, every financial institution will have teams of AI analysts working alongside their sharpest minds. At Endex, we're on a mission to bridge the present to the inevitable by building the most sophisticated digital coworker native in Excel. We're a team working on the frontier of agentic development and applied finance, in close collaboration with leading research labs and backed by OpenAI ($14M Raise in Aug. 2025).

With significant demand after our launch, financial firms across the country recognize agentic AI in financial modeling is the future.

About the Role

Location: New York City Commitment: 5-6 Days In-Person

Brand marketers at Endex shape how the most demanding buyers in finance encounter our work. You'll generate the ideas and ship them end-to-end: brief, vendors, production, launch, and measurement. If you thrive in ambiguity and want to build the brand of a category-defining company, let's chat.

Your Key Responsibilities

  • Own the Brand Voice: Shape Endex's brand across every public surface including website, newsletter, LinkedIn, launch announcements, and sales collateral.
  • Run Campaigns End-to-End: Lead the creative, production, and measurement of Endex's brand campaigns across OOH, conferences, social media, launches.
  • Manage Agencies and Vendors: Build a creative bench across design, video, and production as we scale.
  • Partner Across the Company: Work with product, sales, and leadership to translate complex capabilities into language finance professionals find credible and compelling.
  • Measure and Iterate: Bring analytical rigor to every campaign to know what worked, what didn't, and what to run next.

What We're Looking For

  • Creative and Analytical: You generate the idea, write the brief, hire the vendors, manage the budget, and ship the work.
  • Writer First: You write with the precision a finance audience demands, and your portfolio includes long-form work you personally produced and shipped.
  • Builder: You'd rather ship three good things this month than plan one perfect thing for next quarter.
  • Taste: You have a campaign from any company, any category that you genuinely admire, and you can articulate exactly why it works.
  • Extensible: You adapt fast as the product and company evolve around you.
  • 3+ years of experience in brand marketing

Full-Time Benefits

  • Health & Dental Insurance
  • Monthly Wellness Stipend
  • Retirement Benefits - 401K Matching
  • Competitive Salary + Equity

  • Culture: Fast-moving AI startup backed by OpenAI, working on cutting-edge reasoning models applied to a high-stakes domain. Team is small (~20 people) with a technical majority (37% of headcount in engineering/research).
  • Remote/Hybrid: Offices in New York City (HQ) and team members across Israel, Canada, and Brazil – likely flexible work arrangements.
  • Notable perks/engineering culture:
    • Direct access to OpenAI’s latest models and research collaboration.
    • Opportunity to solve hard problems in financial AI (multimodal analysis, agentic workflows, reinforcement fine-tuning).
    • Emphasis on continuous evaluation and improvement – the team tracks metrics like response latency and reasoning depth.
    • Recent hires from top firms (Jump Trading, Two Sigma, Shopify) and university partnerships (Columbia Business School).
