What are the responsibilities and job description for the Trust Infrastructure Engineer position at iO Associates?
Trust Infrastructure Engineer (Remote)
Our Client is at the forefront of revolutionising how health data is trusted, accessed, and exchanged. Operating within the health technology sector, they are pioneering a health ecosystem where trust is embedded into the very foundation of data architecture. Known for fostering innovation, forward-thinking culture, and collaborative growth, this dynamic organisation offers an inspiring environment for professionals passionate about shaping the future of health data integrity.
Role Overview
This pivotal hire has been driven by the organisation's strategic ambition to build a secure, decentralised, and privacy-preserving trust infrastructure. As a Trust Infrastructure Engineer, you will play a crucial role in creating the cryptographic backbone vital for verifying health records and consent without compromising privacy. This opportunity invites a highly talented specialist to impact the landscape of health data security on a global scale, making a tangible difference in how health information is trusted and managed.
Key Responsibilities
- Design and develop the identity and consent framework, integrating decentralised identifiers (DIDs), verifiable credentials, and real-time, revocable data-sharing mechanisms under user control.
- Incorporate privacy-centric cryptography-such as zero-knowledge proofs, selective disclosure, and encryption schemes-to ensure data security and usability.
- Engineer robust, tamper-evident ledgers with transparent provenance, auditability, and secure key management, establishing trust as an intrinsic system property.
- Collaborate directly with executive leadership to define trust principles across the health ecosystem, influencing architecture and strategic decisions.
- Lead specialised projects focusing on verifiable provenance, on-chain/off-chain anchoring, threat assessment, and innovative consent frameworks.
- Develop and maintain a trusted SDK and cryptographic primitives to facilitate external integrations and future development.
Essential Skills & Experience
- Proven experience in deploying cryptographic, identity, or distributed systems solutions within early-stage or innovative environments.
- Strong systems thinking combined with practical knowledge of applied cryptography, backend systems, and secure architecture design.
- Proficiency in programming with languages like Go, Rust, or similar, with the ability to translate protocols from conceptual models into production-ready code.
- Deep understanding of threat modelling, failure analysis, and the broader human implications of security and trust mechanisms.
- Demonstrated ability to work autonomously with a founder-level ownership mindset, driving projects from conception through to delivery.
Desirable Skills & Experience
- Background in applied cryptography, security engineering, distributed ledger technologies, or decentralised identity solutions.
- Familiarity with zero-knowledge proofs, verifiable credentials, key management systems, or blockchain frameworks such as Hyperledger Fabric.
- Experience working across multiple domains including backend development, blockchain, and AI/NLP is advantageous.
- No healthcare sector experience is necessary; the focus is on building trust-driven systems beyond current technological limits.
