About the Job

zerohash is looking for an experienced Engineering Manager to lead the team architecting and building our open banking data aggregation platform. This is a high-performing team tackling deeply technical, adversarial problems in browser internals and secure automation. We’re looking for a true technologist with a love of programming and a drive for technical excellence. We believe the best managers are technologists first, with a product mindset, who seek to make a larger impact across the organization. You will lead the team building secure, agent-based automation infrastructure (e.g., Chrome Manifest V3 extensions, iOS WKWebViews), transforming unstructured web data into programmable APIs that bridge traditional finance and digital assets.

Responsibilities

• Research and design new methods that push the boundaries of secure web automation
• Lead a team of engineers building the core automation runtime, guiding architecture for resilient UI interactions, reliable programmatic data entry, and robust session routing.
• Partner closely with product and program managers to ensure the open banking roadmap is well understood and the team can plan and execute on expected outcomes.
• Work with the team on technical planning to ensure requirements — such as secure network interception, complex multi-step authentication flows (MFA, Passkeys), and session management — are captured in the technical solution.
• Partner with other Engineering Managers to drive the broader technical roadmap forward.
• Support the engineering team in achieving a high level of technical excellence in browser automation, extension development, and secure data extraction.
• Manage processes to help the team do its best work and interface effectively with the rest of zerohash.
• Recruit, coach, and develop engineers, specifically those specializing in web automation, browser internals, and distributed systems.
• Help engineers establish career development plans within the evolving open banking and web automation space.
• Contribute to engineering-wide initiatives as a member of zerohash’s engineering management team.
• Participate in essential technical, design, and product discussions with leaders across product and operations teams.
• Work with a wide range of stakeholders to build a clear vision for your team’s role in the open banking ecosystem.
• Oversee the success of your team’s projects, driving resiliency, scalability, and coverage across dynamic DOM structures, varying mobile/desktop portal designs, and application suspension states.
• Introduce industry-leading engineering patterns and practices that give the team confidence to operate at scale.
• Make consistent development contributions so as to maintain competency with the codebase and system architecture.

Requirements

• 10+ years of hands-on software engineering experience, deeply focused on advanced web automation, browser internals, extension development, or complex frontend-to-backend data extraction.
• 5+ years of engineering management experience, including managing senior and staff-level engineers.
• BS or MS degree in Computer Science or Engineering OR equivalent years of work experience.
• Proven track record of managing teams that have delivered complex, production-grade browser automation, extension, or data infrastructure products.
• Deep proficiency in TypeScript and JavaScript, specifically regarding DOM manipulation, modern web APIs, and strict browser execution environments.
• Strong backend experience, ideally with Golang (or Node.js/Python), to guide the design of operational infrastructure.
• Strong security fundamentals: deep understanding of secure message passing across trust boundaries (JS bridges, isolated vs. main worlds), secure authentication handshakes, and mitigating DOM-based injection risks.
• Experience guiding teams through distributed systems challenges, specifically managing persistent connections and stateful, multi-hop sessions across ephemeral client runtimes.
• Comfort with ambiguity; the ability to independently lay out and test clear hypotheses, and to coach a team to do the same without well-defined direction.

Preferred

• Proven track record of shipping production-grade browser extensions (Chrome MV3) or complex web automation within mobile native environments (iOS WKWebView, Android WebView).
• Strong understanding of WebAuthn / Passkey protocols and how to integrate them into automated flows.
• Previous engineering leadership experience at a major financial data aggregator or building zero-knowledge/client-side data extraction tools.
• Understanding of cryptocurrency and blockchain technology, including major protocols, on-chain transaction flows, and common crypto security practices.

Benefits

• Healthcare Insurance: zerohash covers roughly 100% of employee premiums as well as a portion of spouse/children (U.S. only)
• Vision & Dental Insurance (U.S. only)
• Chance to earn equity
• Maternity & Paternity leave (after 6 months)
• WeWork All Access Membership
• WFH Yearly Stipend
• L&D Yearly Stipend (after 6 months)
