• Design and build systems from the ground up without cutting corners on security or usability • Develop signing infrastructure and applications to run inside secure computing environments • Collaborate effectively across the company to design and deliver the core product • Write internal product specifications, external developer documentation, whitepapers, etc. • Design and build new product features end-to-end driven by customer requests • Assist in scaling out a world-class engineering team • Develop thoughtful deployment processes and infrastructure to reduce the risks inherent in the software development lifecycle

• Triage, troubleshoot, and resolve customer issues across our SDKs and APIs covering web, mobile, and backend integrations • Debug integrations across a variety of platforms and languages • Identify, reproduce, and document bugs, partnering with engineering to drive them to resolution • Support customers in setting up and verifying integrations, including configuration, auth flows, and signing • Create and maintain example code, troubleshooting guides, and internal playbooks • Spot patterns in recurring issues and propose fixes or improvements to documentation and SDKs • Partner with Product and Engineering to relay feedback and insights from the field • Help improve internal tools and processes to scale our technical support function

• Develop and articulate the overarching engineering strategy and technical vision • Manage a high-performing engineering team and guide the development of Turnkey’s product and infrastructure • Identify and evaluate emerging technologies and trends in web3 and guide their integration into our product and infrastructure • Collaborate with leadership to drive recruitment and onboarding of top engineering talent • Contribute to overall strategic planning and technical decision making • Provide strategic technical guidance and leadership, ensuring intelligent architectural decisions that support our long-term goals • Oversee the design and implementation of modern application architectures, optimized for the unique challenges of web3 • Ensure the scalability, security, and reliability of our infrastructure, addressing the complexities of decentralized systems • Contribute to defining and delivering processes that drive quality & consistency to our product & infrastructure development

• You will partner with Product and Engineering at both the design and development stage to ensure that we implement new features securely, including (but not limited to): • Participating in the implementation efforts • Doing security reviews • Helping with product design decisions • Auditing and surfacing vulnerabilities in our current products • Conducting threat modeling and security assessments for new features and systems, identifying risks early and shaping secure architectural decisions. • Developing and improving our Automated Tooling: further enhancing our automated tooling to scale our product security capabilities and find potential code problems both before and after we deploy • Making the safe way, the easy way: work on defining and building application guardrails so that developers can build securely by default • Investigating and remediating security issues, including vulnerabilities and incidents, and drive long-term improvements to prevent recurrence • Embedding a culture of secure development across engineering, defining practices that influence how Turnkey builds, deploys, and maintains systems at scale.

• Build & Secure Corporate Infrastructure • Design, implement, and manage security for endpoints and distributed systems; deploy and operate our security stack (MDM, EDR/XDR, ZTNA, SSO); enforce zero-trust principles, least-privilege access, and hardening standards • Drive Security Initiatives & Risk Reduction • Lead initiatives around endpoint hardening, access controls, and vendor risk; conduct security design reviews, risk assessments, and vulnerability remediation; develop and enforce security policies and best practices. • Detection, Response & Automation • Respond to security incidents with urgency and technical depth; collaborate on detection rules, alerts, and monitoring; automate workflows and create runbooks and playbooks to scale security operations efficiently. • Foster Security Culture & Education • Evangelize security best practices, build awareness programs, and partner with teams to embed “secure by default” principles into workflows; serve as a trusted security advisor across the organization.

• Build the GTM Motion: Establish Turnkey’s presence in the crypto/fintech market, identifying new verticals and high-value opportunities. • Own Full Sales Cycle: Drive deals end-to-end—prospect, qualify, run technical discovery, design solutions, negotiate contracts, and close. • Craft Deal Strategies: Develop creative approaches for first-of-kind, complex deals; align cross-functional stakeholders internally and externally. • Engage the C-Suite: Build trusted relationships with senior decision makers (CIO, CTO, CISO, CFO) at our prospective and current clients. • Navigate Complex Products: Translate technical capabilities (APIs, security models, integrations) into clear business value for diverse stakeholders. • Influence GTM & Product: Partner closely with founders, exec, Product, and Engineering—bringing market insights back to shape our roadmap. • Represent Turnkey Externally: Act as an ambassador at industry events, conferences, and in strategic networks.
