Cloud Engineer - Crypto

BCB Group

THE ROLE - WHAT WILL YOU BE DOING?  We are seeking a highly motivated and detail-oriented Data Engineer to join our dynamic Data and Analytics team. Reporting to the Head of Data and Analytics, you will play a pivotal role in transforming raw data into actionable insights that drive strategic business decisions.  This position requires a strong analytical mindset, exceptional problem-solving skills, and the ability to effectively communicate complex technical concepts to non-technical stakeholders.  The position is more than just a "warehouse developer" role. You will work cross-functionally with various departments—to understand their workflows, model their data, and build the "connective tissue" that makes the business move faster.  You will be responsible for the end-to-end lifecycle of a data product: from identifying a business need to building the dbt models and ensuring that transformed data is accessible where it's needed most.   KEY RESPONSIBILITIES OWNERSHIP OF THE MODERN DATA STACK (DBT & BIGQUERY) * Act as a lead developer for our dbt project. * Build performant, modular, and well-tested models that turn data into a reliable "Source of Truth." * Apply software engineering rigor to the data stack: version control (Git), documentation, unit testing, and CI/CD. CROSS-FUNCTIONAL AUTOMATION & INTELLIGENCE * Partner with business leads across the company to identify manual processes that can be streamlined through data automation. * Bridge the gap between the warehouse and the business by "closing the loop"—ensuring data isn't just sitting in a dashboard but is actively driving operational tools and decision-making. * AI Integration: Leverage AI tools and LLMs to accelerate development cycles, automate documentation, and explore new ways to enhance data quality. STAKEHOLDER ENGAGEMENT * Act as a consultant to business leads. Don't just "take tickets"—understand the underlying business logic and propose better ways to structure data. * Translate loosely defined business requirements into robust, automated technical solutions. * Data Quality Advocacy: Work closely with stakeholders to define data quality standards and establish feedback loops that ensure data captured in upstream systems is accurate, complete, and fit for purpose. What are we looking for Essential Skills and Experience * 3+ years of experience in a high-growth data environment (Analytics Engineer, Data Engineer, or Technical Data Analyst). * Modern Data Stack Specialist: Deep, practical knowledge of dbt and cloud warehouses (we use BigQuery, but the experience is very transferrable). * Expert-level SQL: You write complex, clean, and performant queries. * Python Literacy: Not a software developer, but you must be comfortable reading code, writing scripts for data manipulation, and handling API. * AI Comfort: You are an "AI-first" builder who is comfortable using AI tools (e.g., Cursor, GitHub Copilot, LLMs) to write code faster, debug, and stay ahead of the curve. * Ownership Mindset: You are comfortable working independently, managing your own roadmap, and taking accountability for the entire warehouse architecture. * Exceptional Communication: You can walk into a room with a non-technical team, understand their pain points, and explain your technical solution in plain English. Desired Skills and Experience: * Workflow Automation: Experience with tools like n8n, Zapier, or similar automation platforms. * BI/Semantic Platforms: Experience with Looker, Thoughtspot, or similar. * Industry Context: Experience in Payments, FinTech, Banking, or Cryptocurrency. * Reverse ETL: Familiarity with moving data from the warehouse back into SaaS tools.   SO, WHAT’S IN IT FOR YOU?        Our people are constantly striving to be the best through operational excellence.

Copper

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.
