Senior Full-Stack Software Engineer

Senior Software Engineer

San Francisco, CA or New York City, NY •Hybrid (Tue–Thu in office) • Full-Time

$180,000 – $230,000 base + equity

Our client is a fast-growing, AI-native platform in the creator economy, building the tools that help creators centralize their online presence, connect with audiences and partners, and run their businesses from one place. Their products serve millions of page views per day and are scaling toward billions. Series A, backed by strong investors, moving fast.

ABOUT THE ROLE

Our client is hiring a Senior Software Engineer to lead and own large parts of the product end-to-end, from ideation through to implementation. The role is balanced across frontend (React/TypeScript) and backend (Python), with meaningful ownership across the stack. You will build and iterate on AI-powered creator tools alongside AI PMs and ML engineers, lead frontend development with an eye for delightful UI/UX, and architect systems that hold up as the platform scales.

AI is not a productivity hack at this company. It is a fundamental shift in how the engineering team scopes, builds, and ships. Every engineer is expected to work this way and raise the bar over time. If you have already changed how you work because of AI tools and have opinions on where they break down, this is the right environment for you.

WHAT YOU'LL OWN

• Build and iterate on AI-powered creator tools working alongside AI PMs and ML engineers
• Build products operating at millions of page views per day and scale them toward billions
• Lead frontend development with strong attention to UI/UX quality
• Design and build backend systems and understand how all moving pieces interact
• Use AI tools as your default starting point across scoping, planning, spec-writing, code generation, debugging, and code review
• Develop a concrete point of view on what AI can and cannot do in product

REQUIREMENTS

Must-Have

• 5+ years of full-stack engineering experience
• AI-native work style. You can speak concretely about how AI tools have changed your output or -pace in the last 6 months
• Production usage of Cursor, Copilot, Claude Code, or comparable, with real opinions on where they help and where they fall short
• Comfort using LLMs beyond code generation: planning, spec-writing, debugging, code review
• Strong TypeScript and React for frontend
• Strong Python for backend
• Familiarity with SQL and Postgres
• Based in or willing to relocate to San Francisco or New York City

Nice-to-Have

• Firebase or Flask experience
• Prior startup experience
• Experience building high-traffic consumer products
• Prior collaboration with AI PMs or ML engineers

Discover our full range of relocation jobs with comprehensive support packages to help you relocate and settle in your new location.

WHAT OUR CLIENT IS LOOKING FOR

The strongest candidates have a genuine pull toward early-stage environments. People who want ownership, impact, and the chance to shape a product, not just contribute to one. Startup experience is a strong signal. Big-company backgrounds can work if the motivation to move early-stage is real and clearly demonstrated.

This role is a strong fit for engineers who are energized by the pace and intensity of building something from the ground up, who find momentum in ambiguity, take pride in shipping fast, and are genuinely excited by the commitment that early-stage company building requires.

This is not the right fit if you are still getting started with AI tooling, or if you prefer to work within well-defined scope rather than help define it.

COMPENSATION AND BENEFITS

• Meaningful equity, 4-year vest, 1-year cliff
• 4 weeks PTO plus federal holidays
• Platinum medical, vision, and dental, 99% employer-paid
• 401(k), gym stipend, professional development stipend
