About the role

The Company 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 For3–10 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

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
