About the role

Make our financial statement views feel like a native spreadsheet: fast rendering of thousands of cells, keyboard navigation, every cell one click from its source.
Rework how long-running research queries stream into the workspace, so analysts see cited results as they arrive instead of waiting on a spinner.
In the longer term, you'll be given ownership of whole functional areas, from extending our platform to a new industry to leading new architecture as our infrastructure scales.

The platform produces cited, verifiable data; you'll package it into the workflows analysts run every day (researching a company, pulling comps, extracting financials into a model) and build the verification interfaces that let them trace any number back to its source.
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.
Ship the UI for a source explorer that lets users trace any value back to its exact origin in the original document.
You'll tell someone their design has a flaw before the PR goes in, not after.
AI: Model-agnostic by design. We currently use Claude and GPT. The model is the replaceable part.
Deep architectural reviews and guidance on system design
"Build anything" budget - dedicated funding for whatever tools, libraries, datasets, or infrastructure you need to solve technical challenges, no questions asked.
Forward-Deployed with Product DNA: We own customer outcomes while building a product company.
Extreme Ownership: If you notice a problem, you own it by making sure it doesn't fall through the cracks.
Production-First Engineering: We design for critical workloads from day one.

You have product taste: you sweat interaction details, and you can take a rough mock, or no mock at all, to a polished interface.
You know what it feels like when the plan changes twice in a day and the work still has to ship.

We're backed by investors who built the modern AI and data stacks, plus the builders of iconic commercial businesses.
This includes founders of OpenAI, Meta AI Research, MotherDuck, dbt Labs and Square as well as PebbleBed, Company Ventures and Mantis VC firms.
PostgreSQL, plus direct integrations with official data sources.

The founding team spent a combined 40+ years at Palantir building the type of large-scale data infrastructure that Kepler requires.
Our co-founder created Palantir's first AI platform and built the analytics engine behind $100M+ contracts.
Our founding engineers led Foundry's core systems - Ontology, Fusion, Workshop, FoundryML - and scaled data products at Meta to 1B+ users.
We've paired this deep technical foundation with a repeat founder profile.
Our CEO built and scaled a data company to $15M ARR before successfully selling it.
He then became Citadel's first Head of Business Engineering, experiencing first hand the problems we are now solving.
We have a team who've been on both sides: building systems like this at massive scale and selling it into the buyers who need it most.
We are committed to the principle of equal employment opportunity for all employees and to providing employees with a work environment free of discrimination and harassment.
