As a publicly traded company, Gemini is poised to accelerate this vision with greater scale, reach, and impact. The Department: Tooling The Role: Principal Software Engineer (Product) As a Principal Product Engineer, you'll set technical direction for the customer-facing platform that defines how millions of users experience Gemini — onboarding, compliance, customer support, and the systems that hold the customer journey together. This is a role for an engineer who operates at the level of the technology itself: someone accountable for company-level initiatives, who drives the hardest technical challenges across organizational boundaries, and who creates the architectural vision that other teams build against. You'll work across backend, web, and mobile, but your leverage comes less from what you build directly than from the direction you set, the leaders you grow, and the frontier you push. We treat AI-assisted development and automation as first-class — an agentic SDLC pipeline where agents plan, implement, and review work through our harness under human gates. As a Principal, you're expected to shape where that frontier goes, define the patterns and operational guidelines other engineers adopt, and advance how the whole organization builds. If you're energized by owning ambiguous, company-critical technical bets and multiplying the engineers around you, we'd love to talk. This role is required to be in person twice a week at our New York City, NY office. Responsibilities: Own the technical vision and architecture for the customer-facing platform, designing for scale and reliability with a multi-year horizon and anticipating needs before they arrive. Review critical designs across organizations and drive the designs for projects involving the hardest technical challenges at the company; act as a key driver of demos and technical direction beyond your own team. Be accountable for one or more core company initiatives spanning onboarding, compliance (KYC/identity), and customer support — carrying them from ambiguity through production and long-term operation. Identify strategic direction in technology and product, proposing and adopting architecture and platform approaches that advance it; tie technical bets clearly to company objectives. Plan and deliver large, complex, cross-org programs with interdependencies across teams and systems, spanning months to years; identify the problems worth solving and advocate for their prioritization. Define patterns, operational guidelines, and engineering practices for your vertical(s), and extend process improvements across teams and command pilot units. Provide critical technical guidance proactively — raising the security, reliability, and quality bar across the organization, and debugging or contributing to the most complex parts of a system when needed. Act as a technical multiplier: mentor and develop engineers and future leaders, share knowledge, delegate to grow others, and lead initiatives across domains, including outside your core area of expertise. Drive the organization toward a strategic vision for strong systems, sustainable practice, and healthy engineering culture; play a critical role in recruiting and bar-raising. Minimum Qualifications: 12+ years of software engineering experience building and operating complex production systems at scale. Recognized expertise in one or two core technical domains, with a track record of being accountable for company-level systems or initiatives end to end. A history of driving architecture and design for the hardest technical challenges across multiple teams or organizations. Demonstrated ability to set technical vision with company-level impact and to bring an increasingly strategic mindset to engineering decisions. Fluency across multiple layers of the stack (backend services plus web and/or mobile) and willingness to go deep wherever a problem requires. Proficiency in a typed language (e.g., TypeScript, Scala, Java, Go) and comfort with JavaScript/TypeScript on web and mobile surfaces. Experience building consumer-facing applications with strong product and UX sensibility. Fluency in using AI coding tools and automation, and a point of view on how to advance an agentic development practice. A record of acting as a technical multiplier — developing engineers and leaders, influencing prioritization across teams, and leading cross-domain initiatives. Excellent communication skills, including the ability to communicate complex technical issues to diverse audiences and build alignment across organizations. Preferred Qualifications: Experience in the crypto or fintech industry, or as a user of crypto products. Deep experience with onboarding, identity/KYC, compliance, or customer support tooling. Experience architecting and operating AI agents or agentic workflows in production at scale. Familiarity with React/React Native and cloud/microservices architecture. A record of driving product and technical strategy with data and experimentation. Experience representing engineering externally (talks, writing) or in cross-company technical collaboration. It Pays to Work Here The compensation & benefits package for this role includes: Competitive starting pay A discretionary annual bonus Long-term incentive in the form of a new hire equity grant Comprehensive health plans 401K with company matching Paid Parental Leave Flexible time off Salary Range : The base salary range for this role is between $192,500 - $275,000 in the State of New York.

The Department: Tooling The Role: Staff Software Engineer (Product) As a Staff Product Engineer on the Tooling team, you'll operate across backend, web, and mobile to shape the customer-facing platform tooling that defines how millions of users experience Gemini — onboarding, compliance, customer support, and the ad hoc projects that keep the customer journey smooth from first touch onward. This is a high-leverage, high-ownership role for an engineer who sets technical direction across multiple systems and teams, moves fluidly up and down the stack, and drives complex, cross-cutting products from ambiguity to production. You'll join a team that treats AI-assisted development and automation as first-class tools. We run an agentic SDLC pipeline where specialized agents plan, implement, and review work through our harness with human guidance. We expect our engineers to wield these tools fluently — offloading toil to automation while holding the decision gates that matter — and we expect our Staff engineers to help shape where that frontier goes next. If you get excited about setting technical vision for customer-facing problems, multiplying the teams around you, and pushing the frontier of how software gets built, we'd love to hear from you. This role is required to be in person twice a week at our New York City, NY office. Responsibilities: Independently scope, design, and deliver solutions for large, complex, cross-cutting challenges spanning backend services, web, and mobile — owning multi-system outcomes end to end. Drive the architecture behind onboarding, compliance (KYC/identity), and customer support workflows that serve millions of users, designing for scale and reliability with the future in mind. Set technical direction beyond your immediate team: plug into designs across the product unit, provide guidance, and help teams avoid design pitfalls. Leverage and help advance our AI coding tools and agentic development pipeline, raising the bar for how the team builds. Own the DevOps lifecycle for the systems you build — building, validating, monitoring, and maintaining them over the long term — and drive key processes like operational review, security, and disaster recovery for your domain. Plan and deliver complex, multi-team, long-term projects, including ones with external dependencies; identify strategic problems and advocate for their prioritization. Conduct meaningful code and design reviews for correctness, style, and information security, providing oversight and coaching that raises quality across teams. Mentor engineers, provide compassionate technical coaching, and contribute to the technical direction, hiring, and engineering culture of the team. Take on the most ambiguous, high-stakes problems and drive them to resolution, tying the work clearly to company objectives. Minimum Qualifications: 8+ years of software engineering experience building and operating complex production systems at scale. A track record of independently designing and delivering large, multi-system or multi-team projects from architecture through operation. Demonstrated ability to work across multiple layers of the stack: backend services plus web and/or mobile — and a willingness to work wherever a problem requires. Proficiency in a typed language (e.g., TypeScript, Scala, Java, Go) and comfort with JavaScript/TypeScript for web and mobile surfaces. Experience building consumer-facing applications, with a strong understanding of UX/UI concepts and product sensibility. Fluency in using AI coding tools and automation as part of your everyday workflow. Expertise in unit and integration testing and a commitment to code health, testing, and maintainability. A customer and product-focused mindset, with the ability to make well-reasoned tradeoffs between speed and quality. Demonstrated technical leadership: influencing architecture and prioritization across teams, mentoring engineers, and building consensus among cross-functional stakeholders. Excellent communication and teamwork skills, including the ability to drive alignment across teams and time zones. Preferred Qualifications: Experience in the crypto or fintech industry, or as a user of crypto products. Experience with onboarding, identity/KYC, compliance, or customer support tooling.
