📍 San Francisco | Work Directly with CEO & founding team | Report to CEO | OpenAI for Physics | 🏢 5 Days Onsite

Founding Full Stack Product Engineer

Location : Onsite in San Francisco

Compensation : Competitive Salary + Equity

Who We Are

UniversalAGI is building OpenAI for Physics. AI startup based in San Francisco and backed by Elad Gil (#1 Solo VC), Eric Schmidt (former Google CEO), Prith Banerjee (ANSYS CTO), Ion Stoica (Databricks Founder), Jared Kushner (former Senior Advisor to the President), David Patterson (Turing Award Winner), and Luis Videgaray (former Foreign and Finance Minister of Mexico). We're building foundation AI models for physics that enable end-to-end industrial automation from initial design through optimization, validation, and production.

We're building a high-velocity team of relentless researchers and engineers that will define the next generation of AI for industrial engineering. If you're passionate about AI, physics, or the future of industrial innovation, we want to hear from you.

About the Role

As a founding Full Stack Product Engineer, you'll be in the arena from day one, building the product experiences that put AI physics capabilities into the hands of engineers and customers. This is your chance to build and own the entire product stack, from intuitive simulation interfaces to backend APIs that power complex physics workloads in production.

You'll work directly with the CEO and founding team to build product features that make foundation models accessible to industrial engineers, create interfaces that visualize complex physics simulations, and design workflows that seamlessly integrate AI into existing engineering processes. You're creating new paradigms for how engineers interact with AI-powered physics simulation tools.

What You'll Do

Build customer-facing applications that make complex physics simulations intuitive and accessible, creating dashboards, visualization tools, and interfaces for foundation model interactions

Design and implement robust backend APIs that power our product features, handle simulation workflows, and integrate with our ML infrastructure and customer systems

Own the full product development cycle from concept to production, shipping features that solve real customer problems and working directly with users to iterate based on feedback

Create data visualization and analytics tools that help engineers understand simulation results, model performance, and physics insights in real-time

Build fine-tuning and customization interfaces that let customers adapt our foundation models through intuitive UIs without needing to write code or understand ML internals

Develop integration tools and SDKs that make it easy for customers to embed our physics AI into their existing CAE workflows, design tools, and simulation pipelines

Design real-time collaboration features that enable engineering teams to work together on simulations, share results, and iterate on designs

Build customer portals and admin tools for model deployment, usage monitoring, billing, and self-service configuration

Instrument everything : Build analytics, logging, and observability into every product feature to understand how customers use the product and where they struggle

Work directly with customers on their workflows, pain points, and feature requests, turning customer conversations into shipped product improvements

Move fast and ship : Take features from prototype to production in days, not months, iterating based on real customer feedback and usage data

This is a role for someone who loves building product that customers actually use, who can move between frontend polish and backend complexity with ease, and is ready to define what AI-powered physics simulation software looks like.

Qualifications

3+ years of full stack development experience building and shipping customer-facing products, ideally at fast-moving startups or product-focused companies

Strong frontend skills : Expert-level proficiency in React, TypeScript, and modern web development. Experience building complex, performant UIs with excellent UX

Solid backend foundation : Strong experience with Node.js, Python, or Go for building APIs, services, and backend systems. Comfortable with databases (PostgreSQL, MongoDB, etc.)

Product mindset : Deep understanding of product development, user experience, and the ability to translate customer needs into shipped features

API design expertise : Experience designing clean, scalable REST or GraphQL APIs that power complex applications

Data visualization skills : Experience with visualization libraries (D3.js, Three.js, Plotly, etc.) and creating interfaces for complex data

Strong system design abilities : Can architect scalable full stack applications, make smart tradeoff decisions, and understand performance implications

Outstanding execution velocity : Ships features rapidly, debugs efficiently, and thrives in fast-paced environments

Strong communicator : Can talk to customers, understand their workflows, and translate technical capabilities into product features they'll love

Ownership mentality : Takes full responsibility for features from concept through deployment, monitoring, and iteration

Bonus Qualifications

CAE / simulation software experience : Familiarity with ANSYS, COMSOL, OpenFOAM, or other engineering simulation tools

Experience building products for technical users (engineers, data scientists, researchers) who have complex workflows and high expectations

3D visualization and rendering experience : Knowledge of WebGL, Three.js, or similar technologies for visualizing physics simulations

Built products integrated with ML models or AI systems , understanding how to surface AI capabilities through great UX

Experience with real-time applications : WebSockets, real-time collaboration features, or streaming data

DevOps and deployment experience : Comfortable with Docker, Kubernetes, CI / CD pipelines, and production operations

Enterprise software experience : Built B2B products with SSO, RBAC, audit logging, and compliance features

Design sensibility : Strong eye for UI / UX design and can work effectively with or without a dedicated designer

Experience at high-growth startups (Seed to Series C) or product-led companies where shipping velocity is critical

Open-source contributions to product frameworks, developer tools, or visualization libraries

Cultural Fit

Technical Respect : Ability to earn respect through hands-on technical contribution and shipped product

Intensity : Thrives in our unusually intense culture - willing to grind when needed to ship critical features

Customer Obsession : Passionate about solving real customer problems and building product people love, not just cool tech

Deep Work : Values long, uninterrupted periods of focused work over meetings

High Availability : Ready to be deeply involved whenever critical issues arise or customers need support

Communication : Can translate complex technical concepts to customers and understand their needs deeply

Growth Mindset : Embraces the compounding returns of intelligence and continuous learning

Startup Mindset : Comfortable with ambiguity, rapid change, and wearing multiple hats - you're a builder first

Work Ethic : Willing to put in the extra hours when needed to hit critical milestones and ship features

Team Player : Collaborative approach with low ego and high accountability

How We're Different

"The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again... who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly." - Teddy Roosevelt

At our core, we believe in being "in the arena." We are builders, problem solvers, and risk-takers who show up every day ready to put in the work : to sweat, to struggle, and to push past our limits. We know that real progress comes with missteps, iteration, and resilience. We embrace that journey fully knowing that daring greatly is the only way to create something truly meaningful.

If you're ready to join the future of physics simulation, push creative boundaries, and deliver impact, UniversalAGI is the place for you.
