Careers

Build the Standard for Forensic Truth.

We are the deterministic counter-weight to the AI hype cycle. We build the infrastructure that proves what actually happened when production broke. No guessing. No hallucinations.

Remote-friendly • NYC • Small team • High bar

A product built on restraint.

Engineering teams don't need another dashboard. They need recall. Déjà links incidents to the code that actually fixed them.

Math over Magic

We do not solve problems with "more LLMs." We solve them with hashing, graph theory, and immutable logs. We trust the commit SHA, not the prompt.

Confidence is earned

If it doesn't pass gates, we don't show it. Trust through restraint.

Zero-Panic Infrastructure

Our customers use Déjà when their house is on fire. Our systems must be boring, predictable, and indestructible. We prioritize correctness over velocity.

The Memo is the Product

We don't do standups. We write 6-page design docs. If the architecture isn't clear on paper, it won't be clear in code.

How we work

A small team with a high bar.

We optimize for clarity, correctness, and user trust. We move fast — but we do it with discipline.

  • Earn trust through restraint
    If something isn't validated, we withhold it — by design.

Who should NOT join

If you want to wrap OpenAI APIs and call it a product, this isn't for you. If you get bored writing unit tests for edge cases, you will hate it here. We are building a Governance Vault, not a toy.

Low ceremony. High signal.

We keep the process small and technical. One screen, one deep dive, one final conversation.

Step 1
Short Intro
Who you are, what you built, and why Déjà.
Step 2
Technical Deep Dive
A real system discussion — trade-offs, gates, internals.
Step 3
Founder Conversation
Alignment, equity, and how you like to work.
