Founding Fullstack Engineer

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

• 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

• 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
• $160,000-$300,000 base salary
• Founding equity and benefits

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.
