You report to engineering leadership and stay hands-on from design through production. Success means shipped outcomes, stronger systems, and teams that move faster. ## What You Will Do - Set 6–12 month technical direction across device, app, and cloud. Turn product priorities into architecture, ownership, and delivery plans. - Lead a few cross-team initiatives from problem definition to launch and adoption. Settle tradeoffs with team leads; flag priority and resource conflicts early. - Write critical-path code, build prototypes, guide migrations, and debug hard production issues. Own how your architecture decisions play out in practice. - Simplify shared systems and interfaces. Improve reliability, observability, security, and developer workflow so teams need less coordination to ship. - Mentor senior and Staff engineers through design, pairing, and shared delivery. Set up lightweight decision practices so teams can act on their own. - Use AI-assisted engineering tools where they improve delivery or quality. Partner with Data Science, AI, and platform owners on production integrations. ## Who You Are - You’ve led architecture and delivery across multiple teams at Senior Staff or Principal scope, with measurable results. - You have deep backend, distributed systems, and cloud expertise and reason well across device, mobile, data, and service boundaries. - You still build and operate production software. You’ve owned hard integrations or migrations and made pragmatic tradeoffs between speed, reliability, security, cost, and maintainability. - You turn ambiguity into focused plans and get alignment from technical and nontechnical partners. - You’ve made other senior engineers stronger technical leaders and can show how your work improved teams beyond your own. Extra Credit - Connected devices, consumer subscriptions, fitness, or digital health. Healthcare integrations and sensitive-data systems. - AI in production products or engineering workflows, with clear quality, delivery, or cost gains. What Success Looks Like - 90 days: Set technical priorities. Ship or materially de-risk one important cross-team initiative. - Six months: Adoption across multiple teams. Measurable gains in delivery speed, reliability, cost, or integration effort. - Ongoing: Independent technical leaders, fewer recurring cross-team blockers, more engineering-leadership capacity for org priorities.
