Title:

Senior Web Platform Engineer (CMS, Next.js \& AI)

Reports To:

Chief Marketing Office

Location:

Remote US or Hybrid if Miami-based

We're looking for a full stack Senior Web Platform Engineer with a mastery of CMS systems, strong design and UX instincts, and deep experience in Next.js to build, maintain, and scale high-performing web platforms across a portfolio of sites for an established, uber successful private investment portfolio company.

You'll also manage and continuously optimize the Content Management Systems (CMS - currently Sanity).

The Opportunity

You won't be maintaining legacy spaghetti code or filing tickets into a void. As the Senior Web Developer, you'll be the architect and engine behind high-performing web platforms. This is a full-stack, hands-on role with real ownership: you'll shape how our brands show up digitally, how our users experience our products, and how our teams build for scale.

Who You Are

• Experience building and managing sites with complex funnels
• Strong experience with Content Management Systems (CMS)- ideally Sanity CMS
• Strong design and UX instincts
• Avid user of Claude and Cursor AI
• You take ownership — when something's broken or could be better, you don't wait for someone to tell you
• You can move fast without leaving a mess; you think about maintainability, not just the deadline
• You communicate clearly with non-technical stakeholders and actually enjoy doing it
• You're curious about AI not just as a buzzword, but as a practical tool in your daily workflow
• You're comfortable with ambiguity and energized by building in a space where the playbook is still being written
• You are based in the Miami, FL area — this is an in-office role

Compensation \& Benefits:

• Competitive Base Salary - $150,000-$200,000 depending on experience
• Free medical coverage and comprehensive dental \& vision insurance for you and your dependents
• An HSA with employer dollars to help you save
• Mental health resources for life's tougher moments
• Company-paid life insurance and short-term disability
• Company-paid parking on-site or train pass
• $60/month cell phone stipend
• 401(k) dollar-for-dollar company match up to 4% with 100% immediate vesting
• A team that genuinely enjoys spending time together — backed by free snacks, drinks, and events that people still talk about long after they happen
• Competitive paid time off, to recharge, so you can show up as your best self
• 12 paid holidays to recharge, plus a floating holiday to spend however you see fit

What You’ll Do

• Own the build, maintenance, and scaling of modern web applications using Next.js and Sanity as your core stack
• Architect CMS schemas, content models, and editorial workflows that make life easier for the teams who use them every day
• Develop and maintain backend services, APIs, and third-party integrations that power web and marketing experiences
• Manage DNS, hosting environments, and deployment pipelines — you know your way around infrastructure, not just the front end
• Put AI tools to work — from content generation and personalization to automation and experimentation — to build smarter, faster experiences
• Implement tracking, attribution, and growth tooling: UTM structures, analytics events, tag management, the works
• Build dynamic, data-driven experiences using JavaScript and server-side logic
• Support HTML email development and integrations with marketing platforms
• Bring interfaces to life with animations and interactive elements, including Lottie and modern motion techniques
• Champion performance, security, accessibility, and SEO across all web properties Collaborate cross-functionally with designers, marketers, and product teams — you're a partner, not just a ticket-taker

What We’re Looking For

• 5\+ years of professional web development experience required
