While everyone else licenses stale data or offloads research to offshore teams, weβre building state-of-the-art OSINT infrastructure to detect allocator activity, fund movements, and investor intentβbefore the market knows.
This isnβt scraping. This is systemic, multi-source intelligence built from public filings, fragmented bios, social breadcrumbs, podcasts, event networks, and dark web trails.
Weβre already live with alpha clients and secured access to major internal allocator datasets. Now we need you to scale our intelligence layer.
π§ Your Mission
Youβll be the architect and executor of the Altss OSINT Coreβa modular system that ingests, deconflicts, and contextualizes thousands of weak signals into structured investor profiles.

(event PDFs, Telegram/Discord drops, local registries, archive.org, alt search engines) - Fusing unstructured media
(podcast transcription + speaker/entity resolution, image metadata, social graphs) - Designing logic for disinformation detection & source credibility scoring
This is not a DevOps role. This is field OSINT with engineering-grade execution.
π§° What Youβll Need
Must have:
- Hardcore experience in OSINT, threat intel, dark web research, or investigative tooling
- Fluency in Python, plus tooling like Playwright/Scrapy for dynamic access
- Deep knowledge of alternative data sources, vertical search, and web infrastructure
- Ability to resolve real-world identities across multiple incomplete digital trails
Creative, first-principles thinker with adversarial mindset (how would I hide this?)
Nice to have:
- Experience with vector DBs, multimodal embeddings, and name-entity disambiguation
- Familiarity with finance, specifically alt assets, fund structures, LP reporting
Prior work in military intel, govtech, security research, or advanced due diligence
π Why Join Altss
