Full Stack Engineering

We're building the ground truth platform for AI. Generic tools hallucinate data, confabulate reports, and don't show their work. We're starting in finance and building the foundational data layer for anywhere decisions depend on trustworthy data.
Kepler was founded by two Palantir veterans (20 years combined) who built core parts of Gotham and Foundry, created Palantir Quiver (the analytics engine behind $100M+ deals with BP and Airbus), led major DoD projects, and served as Head of Business Engineering at Citadel.
Kepler is backed by founders of OpenAI, Facebook AI, MotherDuck, dbt, Outerbounds, and others.

You'll build the core platform that powers Kepler's AI research experience. You own the full stack: React interfaces that financial professionals rely on for critical research, backend systems that process billions of data points, and AI workflows that power million-dollar investment decisions.
This role is for engineers who want to build foundational technology at the intersection of AI and finance, where your code directly impacts how clients make critical business decisions.

Build the frontend: Sophisticated React/TypeScript applications for complex data visualization, AI-powered insights, and seamless workflows. Modern design systems, Tailwind CSS.
Build the backend: Scalable services that orchestrate AI workflows, manage data pipelines, and integrate with enterprise financial tools.
React components, backend services, database optimization, deployment, monitoring.
Integrate AI into production: Language models and AI capabilities powering intelligent research workflows that augment human decision-making.
Build enterprise data integrations: Ingest and normalize data from scattered sources: public filings, earnings transcripts, market data feeds, research reports. Build robust pipelines that transform fragmented data into a unified platform.
Optimize performance: React rendering, bundle size, database queries, API response times. The full stack.
Ship with production excellence: Comprehensive testing, monitoring, deployment pipelines. 7+ years of full-stack development experience shipping production applications at scale

• Frontend: Advanced React, TypeScript, Tailwind CSS, state management, testing frameworks
• Backend: Node.js or Python, API design, PostgreSQL/MongoDB, AWS/GCP
• Experience designing complete systems from database schema to component hierarchies
• Data: Large datasets, visualization, analytics pipelines
• Practices: Git workflows, CI/CD, automated testing
• Thrives in fast-paced environments across the full stack
• Financial services experience preferred but not required

Forward-Deployed with Product DNA: We own customer outcomes while building a product company. That means embedding, iterating, and deploying where our customers are. We show our work, keep our promises, and flag risks before they bite. Keep Raising the Bar: We block time for training, code-health sprints, and deep-dive tech talks.
