Job description

We're partnering with a well-funded, venture-backed startup building purpose-built AI platform software to transform a large, legacy-laden industry. This hire will join the core platform team, building tools and driving software adoption across the firm's portfolio of businesses.

The Role

You'll have significant agency over the full product lifecycle, engineering decisions, and internal stakeholder relationships supporting a rapidly scaling platform.

You'll be responsible for:

• Owning the full development lifecycle: discovery, build, ship, debug in production, and live iteration
• Exercising strong product judgment to translate internal stakeholder feedback into clear build decisions without waiting for specs
• Partnering closely with internal teams (customer success, compliance, ops) to gather requirements, run working sessions, and drive scope independently
• Synthesizing lessons and patterns across portfolio companies so wins at one firm scale into the shared platform
• Working directly with leadership on both immediate engineering needs and long-term platform strategy
• Navigating data sensitivity and regulatory constraints (PII, SOC 2, financial compliance frameworks) as a normal part of shipping

What We're Looking For

• 3–10 years of full-stack product or platform engineering experience
• Proven track record of owning product decisions and shipping software end-to-end without hand-holding
• Experience with full-stack and AI development (modern web frameworks, backend languages, cloud infrastructure, LLMs, RAG, agent frameworks)
• Exceptional communication poise and fluency to earn trust with internal stakeholders and cross-functional partners, including compliance, ops, and finance
• High-agency, founder-minded mindset comfortable in early-stage, fast-moving environments
• Recognizable early-stage startup experience (Seed–Series C) or top technical background preferred
• Tech stack: Python, FastAPI, TypeScript, React, Node.js, PostgreSQL, AWS, ECS, RDS, ElastiCache, EC2, Docker, Playwright, GitHub Actions, Claude Code, Codex
• Willingness to be onsite in NY twice a week

What's in It for You?

• Work directly with the co-founders as a key technical hire in a small, elite team
• Own outcomes end-to-end and build purpose-built tools from the ground up rather than maintain legacy specs
• Significant influence over product direction, engineering standards, and company culture
• Join a lean engineering team where individual impact is highly visible
