We're building the ground truth platform for AI.

Generic tools hallucinate data, confabulate reports, and don't show their work. We made accuracy the only possible outcome: every answer traces to its source, every calculation is reproducible, every insight is defensible. 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.

The Role

You'll build core systems that power Kepler's AI research platform. You'll work across the stack: backend services that orchestrate AI workflows, data pipelines that process billions of data points, and the infrastructure that financial professionals rely on for million-dollar 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.

Within your first 90 days, you will:

• Ship your first production feature with senior mentorship

• Build and deploy a service that handles real financial research workflows

• See your code power research at top financial institutions

• Take ownership of a core system from architecture to production

What You'll Do

• Build backend systems: Scalable services that orchestrate AI workflows, manage data pipelines, and integrate with enterprise financial tools.

• 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.

• Integrate AI into production: Language models and AI capabilities powering intelligent research workflows that augment human decision-making.

• Own features end-to-end: Design to production. Services, database optimization, deployment, monitoring.

• Optimize performance: Database queries, API response times, pipeline throughput. Build systems that scale.

• Ship with production excellence: Comprehensive testing, monitoring, deployment pipelines. You own reliability for what you build.

What We're Looking For

• 4+ years of software engineering experience shipping production applications at scale

• Backend: Python or Node.js, API design, PostgreSQL, AWS

• Architecture: Experience designing scalable systems and data models

• Data: Large datasets, ETL pipelines, analytics infrastructure

• Practices: Git workflows, CI/CD, automated testing

• Strong communicator who can discuss technical trade-offs clearly

• Product mindset: user-focused, iterates on feedback, solves real problems

• Thrives in fast-paced environments

• Financial services experience preferred but not required

Don't check every box? Apply anyway. We prioritize problem-solving ability, systems thinking, and drive to build transformative agentic infrastructure.

Mentorship & Growth

Direct mentorship from engineers who built Palantir's core systems:

• Weekly 1:1s with senior engineers who've architected enterprise-scale distributed systems

• Deep architectural reviews and guidance on system design

• Clear growth path toward technical leadership and system ownership

• Learn by building production systems that power real financial research

• Daily lunch in office

• Development environment budget - latest MacBook Pro, multiple monitors, ergonomic setup, and any development tools you need

• Unlimited PTO policy

• "Build anything" budget - dedicated funding for whatever tools, libraries, datasets, or infrastructure you need to solve technical challenges, no questions asked

• Learning budget - attend any conference, course, or program that makes you better at what we're building
  

Our Operating Principles

• 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 don't win if they don't win.

• Extreme Ownership: Big vision, shared ownership. If you notice a problem, you own it. Authority comes from initiative, not job titles. Once you step up, you're accountable for the outcome.

• Production-First Engineering: We design for critical workloads from day one. Durable execution, blue/green deploys, automated rollbacks, continuous delivery with end-to-end observability. Every change lands safely and stays resilient under real-world load.

• Trust as the Default: People do their best work when confidence is mutual. We show our work, keep our promises, and flag risks before they bite. Trust isn't an aspiration. It's the baseline.

• Keep Raising the Bar: We block time for training, code-health sprints, and deep-dive tech talks. A sharper team and a cleaner stack pay compounding dividends. Continuous learning isn't a perk. It's part of the job.
