We're a cross-functional team of frontend, backend, and mobile engineers building a modular platform that powers products enterprises actually enjoy using. As a Staff Full-Stack Engineer (L5), you are one of the most senior individual contributors on your team and a force multiplier for everyone around you. This is the delivery-focused track of L5: where the Engineering Architect sets cross-team technical direction, and you drive the hardest, highest-impact features from problem definition through deployment and iteration. You lead major product initiatives end to end, designing systems, writing production code across the stack, and mentoring other engineers while owning the quality, velocity, and outcomes of what your team ships. You'll partner closely with Product, Design, and fellow engineers to turn ambiguous problems into shipped, reliable software. This on-site position requires 4 days a week (Monday through Thursday) in our San Francisco HQ office.   You will * Lead major product features end-to-end: problem definition, solution exploration, system design, code execution, deployment, monitoring, and iteration. * Design and implement enterprise-grade services and user-facing experiences across the full stack: backend services, APIs, data models, and frontend. * Create clean abstractions and reusable systems that increase product velocity, so the whole team ships faster without adding hours or complexity. * Own the quality, security, availability, and performance of the systems your team builds. * Drive technical decision-making within your team and influence direction across adjacent teams. * Respond to incidents, identify and resolve bottlenecks, and eliminate sources of recurring toil. * Deliver excellent software through comprehensive peer review, CI, and automated testing. * Provide mentorship and technical guidance to senior and mid-level engineers, raising the bar on craftsmanship. You have * A BS or MS in Computer Science or a related technical field * 10–12 years of software engineering experience shipping and operating production systems at scale * Genuine full-stack depth: fluent in modern frontend and backend, with the judgment to know where a problem is best solved. * A track record of leading complex, multi-quarter initiatives from inception to launch with a strong sense of urgency and ownership. * Strong system design skills in data modeling, API design, and building for scale, security, and reliability. * Demonstrated ability to elevate a team through mentorship, code review, and setting technical standards. * Excellent communication and cross-functional collaboration with Product and Design. * Bias toward clean abstractions and leverage over one-off solutions. Nice to have * Experience with multi-tenant enterprise SaaS and concerns like SSO, RBAC, audit logging, and availability SLAs. * Familiarity with a modern stack including Kotlin, TypeScript, React, and cloud infrastructure (AWS, Kubernetes). * Experience building platform features or integrations that other teams or customers build on top of. Nice to have * Experience in high-growth or startup environments where platforms evolve rapidly. * Familiarity with SOC 2, ISO 27001, or similar compliance frameworks. * Experience partnering closely with security teams on secure-by-default infrastructure and access models. * Exposure to service mesh, advanced networking patterns, or multi-region architectures. * Experience applying AI-assisted tools or workflows to improve infrastructure safety, speed, or operational signal. You'll get * Deep engagement across the full technical stack, contributing to vital product domains including external interfaces, core platform architecture, and developer productivity tooling. * A high-leverage environment defined by tight collaboration between engineering, product management, and design functions. * Full ownership and architectural autonomy over high-impact features spanning both frontend and backend systems. * A deliberate placement process to ensure your core competencies and professional aspirations are perfectly matched with the right product initiative. * A comprehensive rewards package featuring competitive pay, robust benefits, and clear pathways for career advancement.   By applying for this position, you acknowledge that you have fully read and understand the job requirements and received the Envoy Privacy Notice for applicants, which is linked here.
