What You'll Do
- •Own the architecture and long-term direction of the intelligence-fusion platform, making the technical decisions that determine where the system goes, not just how it runs today.
- •Design new detection and correlation approaches that anticipate how manipulation and evasion evolve, rather than codifying patterns we've already seen.
- •Ingest new on-chain and OSINT data sources, and extract more signal from the data pipelines already integrated, including finding value in sources we aren't using yet.
- •Build automation that closes the gap between a signal firing and a case being assigned, removing the manual steps that slow investigators down.
- •Pair directly with analysts and investigators to translate their instincts and manual workflows into repeatable, auditable tooling that holds up to legal scrutiny.
Benefits
- •Competitive salary & equity
- •Unlimited PTO
- •Full Health, Vision, & Dental coverage
- •401k match
- •Hardware setup: new MacBook Pro, big display, & accessories

What We're Looking For
- •Ownership mindset with a track record to back it up. You've owned a complex data system end-to-end over a multi-year horizon, made real architecture decisions, and left it materially better than you found it.
- •Senior data or detection engineering experience at scale. Deep fluency with SQL, Python or equivalent, data pipelines, and both scheduled and event-driven systems. You make architecture decisions, not just implement them.
- •Hands-on depth in data fusion and entity resolution. You can take heterogeneous, messy inputs, resolve them to a shared entity model, and reason carefully about scoring and corroboration so real signals rise and noise stays down.
- •Comfort working directly with investigators and analysts. You translate domain instinct into a working technical capability, and you care that what you build holds up under legal and audit review.
- •Genuine interest in market integrity and the problem of catching people who don't want to be caught. The mission has to matter to you, not just the engineering.
- •(Plus) Prior experience working alongside fraud, trust and safety, or investigations teams.
- •(Plus) Exposure to on-chain or crypto data analysis, including working with blockchain transaction data, wallet clustering, or similar.
