About the role

  • 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.
  • Redesign how our agent orchestrator handles failures and retries so that a bad extraction from one source doesn't block the rest of a parallel workflow

Responsibilities

  • 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.
  • 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
  • Learn by building production systems that power real financial research
  • We own customer outcomes while building a product company.
  • "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.

Requirements

  • We believe strong engineering fundamentals and experience in other languages is what matters.
  • You know what it feels like when the plan changes twice in a day and the work still has to ship.

Nice to have

  • 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.

Skills

  • Add verification rules that cross-check extracted values across multiple sources and surface conflicts with full provenance on both sides
  • Great teams compound.
  • Every hire raises the bar, every win gets named, every person gets the tools and runway to grow.
  • Kepler is an Equal Opportunity Employer and prohibits discrimination and harassment of any kind.

Benefits

  • 100% covered top-of-the-line medical, dental, and vision insurance for employees and their families.
  • HSA maxed by the company to the IRS limit.
  • Automatic coverage for life, AD&D, and disability insurance.
  • Unlimited PTO policy.
  • Learning budget - attend any conference, course, or program that makes you better at what we're building.

Company info

  • 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.
