Founding Software Architect
Remote (EMEA)
We’re looking for engineers to help architect the proof layer for internet advertising.
We’re open to two profiles: Senior Engineer (7+ years preferred): ready to architect, ship and lead. Research-driven Graduate Engineer: exceptional university talent or lab assistant with hands-on projects in cryptography, AI or distributed systems.
You’ll help design and build:
• The Proof Engine: real-time ZK verification
• The “Etherscan of advertising” for total transparency
• Privacy-Preserving AI: federated learning models that match ads without surveillance
• Hybrid Systems: off-chain speed with on-chain settlement and blockchain-anchored proofs
Our Stack: Rust • Go • TypeScript • React • Swift/Kotlin • PostgreSQL • Redis • Redpanda • gRPC • ZKPs • Merkle Proofs • HMAC • Federated Learning • GCP • Pulumi
You’ve built serious systems (adtech, blockchain, cryptography or AI) and want your code to matter. You’re sharp, move fast and care about privacy at a fundamental level.
Bonus points:
• Zero-Knowledge, MPC or differential privacy
• DSP/SSP or programmatic ad experience
• High-frequency / low-latency systems
• Equity-based role, transitioning to a salaried position after funding (equity retained; current freelance payment: $2,000 net/month; target salary: $200K gross/year)
• Flexible, remote-first work with async collaboration
• Gym, health and wellness support
• Mental health allowance, therapy or coaching when needed
• Private health insurance (family included, post-funding)
• Learning budget: Coursera, language courses or conferences/events
