## Job description

Rockstar is recruiting for a fast-moving, venture-backed startup that builds AI workers for non-production departments in American manufacturing. The company is backed by a16z Speedrun and angels from Brex, Xwing, and Betterment, and is on a mission to rebuild the digital foundation of American manufacturing.
The Role
This is a hands-on senior individual-contributor role at the intersection of applied AI, product, and distributed systems. The role holder will take ambiguous customer problems and complex product initiatives, turn them into focused architectures, and ship simple, reliable systems in production.
They will build AI workers across the stack, from customer-facing experiences to long-running agent workflows and integrations with legacy ERPs and CRMs. They will lead 0→1 initiatives, improve agent performance and reliability, help set model and agent strategy, and evolve infrastructure as customer usage and model capabilities grow.
Technical leadership at the company means writing and operating core product code while raising the bar for the team through clear technical writing, thoughtful code review, mentorship, and better developer tooling. The stack is TypeScript end-to-end with React, Node.js, and PostgreSQL, running on AWS and Kubernetes.
What You’ll Do
Lead complex product initiatives from customer discovery and technical design through implementation, rollout, and production operation
Turn broad product requirements into focused architecture documents, clear tradeoffs, and incremental execution plans
Build core AI product experiences and the agent workflows, tools, and integrations behind them
Improve agent performance, reliability, and cost as usage grows and new models arrive
Design and operate distributed systems, including queues, workers, observability, and failure recovery
Help set technical strategy across models, agent architecture, context management, infrastructure, and developer experience
Raise the engineering bar through simple design, testing, code review, and operational follow-through
Mentor engineers and create patterns, documentation, and feedback loops that make the team more effective
Who You Are
You have 5+ years of product engineering experience and a track record of designing, shipping, and operating important systems; experience across both a high-growth startup and a scaled engineering organization is a plus
You are a strong systems thinker who can reduce a complex domain to clear boundaries and maintainable software
You have a product mindset: you learn how customers work, notice patterns, and connect technical decisions to customer value
You care deeply about code quality and reliability, but avoid abstraction or complexity for its own sake
You communicate clearly with technical and non-technical teammates and make others better through writing, code review, mentorship, and candid feedback
You form thoughtful opinions about fast-moving AI technology and choose models, architectures, and context strategies based on evidence
You are ambitious, resourceful, action-oriented, and team-first; you care about strengthening American manufacturing and are excited to work in person five days a week in NYC
Bonus Points
Deep experience with TypeScript, Node.js, React, or PostgreSQL
Experience with AWS, Kubernetes, queues, streaming, caching, retries, consistency, and observability
Experience building a large surface area of third-party integrations, especially with legacy systems
Experience building software for manufacturing or another operationally complex industry
About the Company
Revitalize an industry. Rebuild America’s manufacturing backbone.
America builds satellites, jet engines, semiconductors, and more with world-class precision, but the software running factory offices is decades behind. Estimators, procurement teams, and engineers still lose hours to spreadsheets, PDFs, and manual data entry.
The company builds AI workers for non-production departments, such as inside sales, quoting, and procurement. By removing back-office bottlenecks, it helps US manufacturers move faster, grow, and compete globally.
The company is backed by a16z Speedrun and angels from Brex, Xwing, and Betterment. Join in rebuilding the digital foundation of American manufacturing.
The Founders
Co-Founder & CEO: Began his career at Acer and Northrop Grumman, then advised industrial companies at Bain. At Xwing, he helped scale the company and led GTM through its acquisition by Joby Aviation. He holds an MBA from Stanford and a BA from USC.
Co-Founder & CTO: Began at Meta, then founded a YC-backed startup that was acquired by a media company. He later became a founding engineer on a major spend management product, and ultimately the Head of Engineering for that organization. He holds a BS in Computer Science from USC.
How the Company Works
In person every day in NYC for high-bandwidth collaboration
Talks to users constantly: the company builds with manufacturers, not for them
Owns outcomes end-to-end and drives solutions without waiting for permission
Prefers simple, incremental systems that solve the real problem and are easy to operate
The Company’s Values
