Kepler · New York City ·
High-stakes industries are falling behind on AI adoption. Their workflows can’t afford wrong answers. And AI can’t be trusted to give right ones because of hallucinations. The barrier isn’t that the models aren’t smart enough. It’s that no one can verify what they produce. The fix isn’t a better model, it’s a trust layer: every output traceable, every calculation auditable, every answer reproducible.
Kepler is the agent harness - the infrastructure layer that wraps around AI models to make their outputs reliable, traceable, and verifiable. The model is a replaceable component. The harness is the product.
In Kepler's architecture, the LLM orchestrates - it decides what data to gather, what to compute, how to structure the output. But every actual data point, every extracted value, every calculation flows through deterministic code pipelines. The LLM never touches the data itself. Every value carries provenance metadata back to its exact source. Every computation is auditable and reproducible. Verification loops cross-check outputs before users ever see them.
We started in finance because the stakes are highest and the tolerance for error is zero. We’ve built a finance research product that lets analysts supercharge their workflow: pulling comparables, building models and researching filings. No more double-checking every number AI spits out. Every number tracing back to the source, every time.
But the architecture - provenance, deterministic computation, verification - applies anywhere trust in AI output matters: chemicals, legal, healthcare. Models are commoditizing fast. The trust layer is what's missing and the market is massive.
The founding team spent a combined 40+ years at Palantir building the type of large-scale data infrastructure that Kepler requires. Our founding engineers led Foundry's core systems - Ontology, Fusion, Workshop, FoundryML, created Palantir's first AI platform 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’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.
You'll be the technical architect of our most strategic client relationships. You'll embed directly with our lighthouse customers, sophisticated financial firms and research organizations, to deploy, customize, and extend Kepler for their specific workflows. This is the engineering role that lives our core principle, Forward-Deployed with Product DNA: you own client outcomes while building the platform that serves the entire market.
This role is for engineers who want to work where the product meets the market, where your code directly shapes million-dollar research outcomes.
In the first few weeks you might:
Sit with a Portfolio Manager at an institution with $10B+ AUM to scope a workflow, then go build it.
Ship a vertical app on top of our core platform for a design partner and watch their analysts use it the same week.
Design an integration with a client's research stack (Bloomberg, CapIQ, proprietary systems) with provenance preserved end to end.
Take a gap you found in the field and turn it into a core product feature.
In the longer term, you'll own whole customer engagements and verticals end-to-end, rotating between forward deployed work and core platform development so field insights land directly in our architecture. In a small team, there's nobody to hand things off to.
We’re a close team, working together in an office in New York. We use AI tools heavily - Cursor, Claude Code, whatever makes us faster. Fluency is assumed. Our users are analysts at firms where a wrong number costs real money. The feedback loop on what you ship is hours, not quarters.
The pace is startup-fast but the engineering bar is high. We care about getting things right, not just getting things out. If you've worked somewhere that moves fast but ships broken software, this is different. If you've worked somewhere that's rigorous but slow, this is also different.
The team has strong backgrounds and low ego. We expect everyone to roll up their sleeves and handle the unglamorous problems: the weird regressions, the subtle bugs, the last minute debugging session before a demo. We move as a team, not as a collection of individuals.
You've shipped production systems and you care about whether they're correct - not just whether they work on the happy path. You think about failure modes before someone asks you to.
You're comfortable in a codebase you didn't write, moving between a client conversation and the code that answers it in the same day. You're drawn to early-stage not for the title but because you want your work visible in the product, not abstracted behind three layers of management.
From the technical side:
5+ years building production software, with a track record of deploying complex systems in enterprise environments. No upper limit, comp scales with experience.
Client-facing technical experience: you've been a Forward Deployed Engineer, Solutions Engineer, or similar, working directly with enterprise customers.
Full-stack skills: strong in Python/TypeScript, comfortable across distributed systems, data pipelines, and API development.
You've handled enterprise integration: SSO/SCIM, RBAC, database integrations, and the security requirements that come with them.
Comfortable presenting to C-level executives and technical teams alike.
Willing to travel regularly (30-50%) for on-site client engagements from our NYC HQ.
From the personal side:
You care what the analyst does with what you shipped, not whether the code was clever.
You’d rather fix something than file a ticket about it.
You’ll tell someone their design has a flaw before the PR goes in, not after.
You communicate before it’s a problem, and when a teammate needs something from you, they don’t have to ask twice.
You know what it feels like when the plan changes twice in a day and the work still has to ship.
Don't check every box? Apply anyway. We prioritize speed of learning, problem-solving skills, client empathy, and drive to transform how financial research works.
Backend: Rust - agent orchestration, data extraction, computation pipelines.
Frontend: TypeScript, React - the analyst workspace and verification interfaces.
Data: PostgreSQL, plus direct integrations with official data sources.
Infra: AWS.
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.
Clear growth path toward technical leadership and system ownership.
Learn by building production systems that power real financial research.

"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.
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.
Forward-Deployed with Product DNA: We own customer outcomes while building a product company. We don't win if they don't win.
Extreme Ownership: If you notice a problem, you own it by making sure it doesn’t fall through the cracks. 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.
Communicate with Intent: Great work disappears without great communication. We push information to the people who need it, when they need it. Silence is never the safe choice.
Earn it Every Day: Your work speaks for itself. We create an environment where the best idea wins, the strongest work gets recognized, and everyone is held to the same high standard.
Keep Raising the Bar: Great teams compound. Every hire raises the bar, every win gets named, every person gets the tools and runway to grow.
