About RealityFoundation
RealityFoundation is a non-profit building the authenticity layer for digital media.
We certify photos and videos at the moment of capture. The raw media and its metadata are hashed, signed, and anchored to a public blockchain before anything can touch them — so a media record can be proven authentic, not merely believed. Our work is open source, built on the C2PA standard, and runs on infrastructure Europe controls.
We do this because the alternative is already arriving. Once synthetic media is indistinguishable from real media, everything unproven becomes deniable — insurance claims, court evidence, journalism, public accountability. Detection is a losing race: it will always be one model behind. Provenance at the origin is the only thing that holds.
We are small, early, and public about our work. The people who join now decide what this becomes.
Must-have technical skills
- Solid experience with Bitcoin blockchain workflows and OpenTimestamps-based anchoring
- Hands-on experience building and maintaining cryptographic hashing pipelines
- Familiarity with IPFS and decentralized storage workflows
- Backend development proficiency (Go, Rust, or Python preferred)
- Experience designing and maintaining REST or gRPC APIs
- Understanding of C2PA or related content provenance standards is a plus
What you bring
- You care about technical correctness and do not like shipping systems you do not fully understand
- You can work autonomously in an early-stage environment with incomplete specs and high ambiguity
- You communicate clearly with non-technical teammates and explain trade-offs in plain language
- You share our belief that media integrity is a public good worth protecting
What you’ll do
- Own the end-to-end hashing and certification pipeline from media capture to Bitcoin/OpenTimestamps record
- Design and implement IPFS-based storage architecture for certified media
- Build and maintain backend infrastructure that connects capture clients to the certification layer
- Contribute to the open-source codebase and document architecture decisions clearly
- Work closely with security and product to keep the pipeline correct, auditable, and resilient
What we offer
- €35,000 – €55,000 / year gross
- Brussels or remote
- Tools and learning budget A real budget for equipment, training, and relevant conferences
- Your work is public What you build here stays in the open, under your name
- Growth, impact, and ownership You can grow into the role and shape how it evolves, while working with a small dynamic team on a mission that protects trust in digital media and lets you be part of meaningful change
The selection process
Four steps, about three weeks. You will know where you stand at every one of them.
- Application review A person reads it — no model screens you out. You hear back within 7 working days either way
- Intro call (30 minutes) With the founding team. What you want, what we're building, whether the shapes match
- Working session You get a simplified media-to-certificate flow plus a reliability incident, then walk us through the changes you would make and why in a practical session
- Team call (45 minutes) With the people you'd actually work with, then references
Decision within 7 working days of the last step. If it's a no, we tell you why. We know that's rare. It shouldn't be.
