We're building product-authentication technology for physical goods, with customers in India and Europe. You'd be our first technical hire.

The role

Own the security-critical core of the platform — the architecture, the first build, and its independent security review.

What you'll do
Build low-latency services that verify authenticated messages from secure hardware
Own key management end to end — HSM or cloud KMS, key derivation, rotation and audit
Build strongly consistent state for replay protection under concurrency
Threat-model the system and take it through external security audit
Support device provisioning with hardware and platform partners
Help hire the team that follows

Must have
6+ years of backend engineering, including ownership of a security-critical production system
Applied cryptography — symmetric primitives,



MAC verification, key derivation
HSM or cloud KMS in production
Distributed systems: solid consistency, idempotency, concurrency
Low-latency API design

Strongly preferred — any one
Secure NFC or smart cards (MIFARE DESFire, NTAG DNA family, SUN/SDM)
EMV, SIM/eSIM, transit ticketing, access control or PKI
Verifiable credentials or decentralised identity
Smart-contract security

What we offer
Ground-floor ownership of the core system
Technical co-founder track with meaningful founding equity To apply

Message me with a few lines on the security-critical system you're proudest of — and what went wrong in it.
