Since being founded in 2018, Copper has been building the standard for institutional digital asset infrastructure with a focus on
custody, collateral management, and prime services.
Led by Amar Kuchinad, Copper's Global CEO, the firm provides a comprehensive suite of custody, trading and settlement solutions
that reduce counterparty risk and bring greater capital and operational efficiency to digital asset markets. At the heart of
Copper's offering is Multi-Party Computation (MPC) technology – the gold standard in secure custody. Copper’s multi-award winning
custody system is unique in that it can be connected to centralised exchanges, DeFi applications and even staking pools without
the assets leaving the custody.
Built on top of this state-of-the-art custody, ClearLoop is the first solution in the market that overcomes a growing industry
challenge; counterparty risk with exchanges. This solution underpins a full prime services offering, connecting global exchanges,
and enabling customers to trade and settle directly from the safety of their MPC-secured wallets. By reducing settlement time for
transfers to a few milliseconds (without blockchain network dependency) and offering enhanced security measures, ClearLoop is
rapidly reshaping the way asset managers trade and manage capital.
In addition to industry-leading security certifications, Copper has one of the strongest insurance coverages in the industry from
an A+ rated insurer, positioning the firm as the partner of choice for institutions seeking to safeguard their assets.
Department/Team Purpose:
Copper provides institutional digital asset custody, settlement, and collateral management services across a wide range of
blockchains and integrated venues. Information Security protects the firm's platforms, client assets, and regulated entities
across the group.
Role Purpose:
The Principal Security Architect is the senior technical authority for security architecture at Copper. The role reports to the
CISO and partners closely with Engineering. The holder sets architectural direction, reviews and approves designs for major
change, and acts as the firm's reference point on the security of the systems, protocols, and integrations Copper depends on. The
role is predominantly architecture and assurance, with limited hands-on solution design in the cloud and integration space where
reference patterns are needed.
Key Responsibilities:
Architectural authority
* Hold formal security sign-off authority for major changes to Copper's platforms, infrastructure, and integrations.
* Shape and maintain the security architecture patterns, principles, and reference designs that engineering teams build against.
* Provide the senior technical security position in architectural and business decisions, including escalations where security
and delivery pressures conflict.
Custody, signing, and cryptographic architecture
* Provide architectural security leadership over Copper's signing infrastructure, working alongside specialist engineering and
cryptography teams. Scope covers the people, process, and operational design around MPC-based signing. Solid conceptual
grounding in threshold cryptography and signature schemes is required; cryptographer-level work is not.
* Review and approve changes to transaction construction, signing flows, approval policy, and key lifecycle operations.
* Provide architectural assurance over chain-of-trust constructs adjacent to custody, including verifiable build pipelines,
hardware-backed code signing, and authenticator-bound administrative paths.
Multi-chain and integration security
* Reason at architectural depth across the range of blockchains Copper supports, including EVM, UTXO, and account-based non-EVM
families. This requires a working understanding of transaction construction, signing semantics, consensus assumptions, and
validator and staking models across these environments, without being a protocol engineer in any of them.
* Assess third-party smart contract architectures, implementations, and audit reports to a level sufficient to understand the
exploit and risk surface, without performing line-by-line code review.
* Review first-party integrations with partner networks, including those underpinning staking and similar on-chain participation,
and form a defensible security position on the operational and contract risk Copper inherits.
Settlement, collateral, and off-exchange architecture
* Provide architectural ownership of the security model for Copper's settlement, collateral mirroring, and off-exchange product
surfaces.
* Reason about the trust boundaries between Copper, venues, and clients, and ensure architectural controls match the obligations
each side carries.
Identity and access architecture
* Own identity and access architecture as a dedicated pillar of the role.
* Set patterns for workforce, workload, and third-party identity across Entra ID, federated SSO, OAuth2 / OIDC, SAML, and modern
authenticators.
* Govern entitlement design, privileged access, and access models for contractors, vendors, and external operators.
Cloud and platform security
* Maintain working architectural fluency in both AWS and Azure, including network topology, segmentation, secrets handling, and
platform telemetry.
* Produce reference patterns and, where needed, direct integration designs in the cloud and platform space.
Third-party and protocol risk
* Lead technical security review of vendors, integrated venues, and protocols, including challenge of assurances that do not
stand up to scrutiny.
* Support client and counterparty due diligence on the technical content most likely to be misrepresented or under-specified.
Policy, regulatory, and assurance support
* Maintain a working understanding of the regulatory regimes applicable to Copper's licensed entities sufficient to translate
architectural decisions into language Compliance and GRC can defend. Primary ownership of regulatory positioning sits
elsewhere.
* Contribute to security policy, standards, and control framework development as the senior technical reviewer.
* Participate in resilience exercises and incident reviews where architectural input materially shapes the outcome.
Skills and Experience:
Essential
* Multi-chain architectural literacy. Able to reason across EVM, UTXO, and non-EVM account-based chains at the level of
transaction construction, signing, consensus, and validator models. Comfortable assessing third-party smart contract designs,
implementations, and audit reports for exploit and risk surface without performing code review.
* Custody and signing architecture. Strong conceptual grasp of threshold signing, signature schemes, and key lifecycle. Able to
design and challenge the operational architecture around signing, separation of duties, approval policy, key ceremony
equivalents in MPC, and recovery, to a high standard.
* Settlement and collateral architecture. Demonstrable experience reasoning about settlement, collateral, and off-exchange
constructs, including trust boundaries between custodians, venues, and clients.
* Identity and access architecture. Senior-level experience designing and governing identity across Entra ID, federated SSO,
OAuth2 / OIDC, SAML, and modern authenticators. Comfortable with entitlement governance and third-party access design.
* Cloud security. Working architectural understanding of AWS and Azure, including the ability to produce reference patterns and
limited direct integration designs.
* Architectural authority and judgement. Track record of holding sign-off on significant designs, taking defensible positions
under uncertainty, and owning residual risk.
* Change review and assurance. Comfortable reviewing the work of engineering peers, infrastructure changes, and vendor designs,
and able to hold the line where it matters.
* Communication. Able to operate credibly with engineers, senior business stakeholders, auditors, and regulators in the same
week, without losing precision at any of them.
Desirable
* Familiarity with chain-of-trust constructs including verifiable builds, reproducible build pipelines, and hardware-backed code
signing.
* Awareness of the regulatory landscape relevant to digital asset custody and trading (for example FCA, FINMA, FSRA /
ADGM, MiCA).
* Compliance familiarity across ISO 27001, SOC 2, and NIST CSF / 800-53, with the ability to map controls cleanly between them.
* Enterprise architecture grounding (TOGAF, SABSA) where it complements rather than replaces technical depth.
