About The Position

About Kepler
Kepler is building the ground truth platform for AI.
AI is great at understanding what you're asking. It's terrible at giving you answers you can trust. Generic tools hallucinate data, confabulate reports, and provide insights without showing their work. In finance, where being wrong costs millions, that's not acceptable.
We solved this by making accuracy the only possible outcome. Every answer traces to its source. Every calculation is reproducible. Every insight can be defended with complete confidence. The result: faster decisions, deeper analysis, and a competitive edge where synthesizing information more thoroughly than competitors translates directly to performance.
We're starting in finance and building the foundational data layer for anywhere decisions depend on trustworthy data.
Founded by two Palantir veterans with 20 years of combined experience building core parts of Gotham and Foundry. Our founders created Palantir Quiver, the analytics engine behind $100M+ enterprise deals with BP and Airbus, architected core compute and data systems, led major Department of Defense projects, and served as Head of Business Engineering at Citadel.
We're backed by founders of OpenAI, Facebook AI, MotherDuck, dbt, Outerbounds, and others.
The Role
You'll define the technical foundation of Kepler's AI research platform. You'll own the architecture of our most critical systems: 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. You'll set technical strategy, drive cross-cutting initiatives, and elevate engineering quality across the organization.
This role is for engineers who want to shape the technical direction of a company building foundational technology at the intersection of AI and finance, where your architectural decisions directly impact how clients make critical business decisions.
Within your first 90 days, you will:
Own and deliver a platform-critical system that shapes technical direction
Establish architectural patterns and standards adopted across the engineering org
Drive a cross-cutting technical initiative from conception to production
Build relationships across the company and influence product and engineering roadmap

Requirements

• 10+ years of software engineering experience with a track record of technical leadership
• Architecture: Designed and scaled distributed systems handling mission-critical workloads
• Backend: Deep expertise in Python or Node.js, API design, PostgreSQL, AWS
• Data: Large-scale data systems, ETL pipelines, real-time processing
• Technical leadership: Experience setting technical direction, driving cross-functional initiatives, and mentoring senior engineers
• Influence: Ability to align engineering, product, and business stakeholders around technical decisions
• Communication: Can articulate complex technical trade-offs clearly to any audience
• Track record of building and shipping systems that matter
• Thrives with high autonomy and high ownership
