Our client is a cryptocurrency company reshaping the market with a steadfast commitment to transparency and safety. They provide secure, transparent crypto-backed lending solutions that let individuals and businesses unlock liquidity from their digital assets without selling them — notably, they never rehypothecate client collateral. Alongside their lending business, they operate an OTC desk that facilitates large-scale cryptocurrency trades with competitive rates, swift execution, and full transparency. As the company continues to grow, they are looking for a Deputy CTO to work as a close technical partner to their CTO — someone who can help translate complex technical concepts for clients and customers, contribute hands-on to the platform, and help shape the engineering direction of the company. This is a unique opportunity to operate at the intersection of technology, client relationships, and strategic decision-making within a fast-moving, security-first crypto company.
The Role
The company is seeking a hybrid technical leader and trusted right hand to the CTO — part senior engineer, part strategic advisor, part client-facing technologist. The successful candidate will split their time between hands-on engineering work and supporting the CTO in client and partner conversations, helping bridge the gap between deep technical detail and business needs. This role suits someone who wants genuine ownership and executive-level visibility, stepping into a position that sits just below the CTO with a clear path to grow alongside the business.
Responsibilities
- Work directly alongside the CTO on architecture decisions, platform strategy, and technical roadmap planning
- Join client, partner, and prospect calls to speak credibly to the company's lending and OTC infrastructure, security model, and technical capabilities
- Translate complex technical and crypto-specific concepts (custody, collateral management, settlement, security architecture) into clear language for non-technical stakeholders
- Design, build, and maintain core platform features across the lending and OTC systems
- Help evaluate and implement security best practices, given that security is core to the company's value proposition
- Represent engineering in cross-functional discussions with compliance, operations, and leadership
- Deputise for the CTO where needed — reviewing technical proposals, vetting vendors/partners, and driving technical due diligence for institutional clients
- Mentor other engineers and help scale engineering processes as the team grows
- Stay current on developments in crypto lending, custody, and market infrastructure to inform product decisions
Requirements
- 6+ years of software engineering experience, including senior or lead-level responsibility
- Experience in crypto/blockchain, fintech, or financial services (lending, trading, custody, or payments preferred)
- Strong communication skills — comfortable explaining technical concepts to clients, executives, and non-technical stakeholders
- Solid understanding of security best practices, particularly as they relate to handling sensitive financial data and digital assets
- Proven ability to work closely with leadership and operate with a high degree of trust and autonomy
- Experience with backend systems, APIs, and infrastructure at scale
- Comfortable in a fast-paced, high-accountability startup environment where priorities shift quickly
- Must be based in or willing to relocate to Sydney
Desirable
- Direct experience with OTC trading desks, crypto lending platforms, or digital asset custody solutions
- Familiarity with blockchain protocols, wallet infrastructure, or smart contracts
- Prior experience in a client-facing technical role (solutions engineering, technical account management, or similar)
- Background in regulated financial services and an understanding of compliance considerations in crypto
- Experience presenting to institutional clients, investors, or partners
What's on Offer
- A high-impact, senior role with direct exposure to leadership and strategic decision-making
- The opportunity to help shape the technical direction of a growing crypto-lending platform
- A security-first, transparency-driven cultur
