仕事内容
Mercari is seeking an Engineering Manager for its Mobile Enablement team, responsible for leading a team of senior mobile engineers to build and maintain a scalable mobile ecosystem. This role involves defining technical strategy, driving execution of mobile libraries, CI/CD, and release management, and fostering cross-functional collaboration. The manager will focus on simplifying engineering workflows and enabling product teams to deliver value efficiently, while navigating unique challenges in a dynamic, influence-driven environment.
Work Responsibilities
- Lead, mentor and sustain a team of senior and principal-level mobile engineers across iOS and Android by building an environment where they can operate autonomously, collaborate effectively across boundaries, and translate deep expertise into scalable organizational mechanisms.
- Define and drive the technical vision for Mercari's mobile enablement, including CI/CD infrastructure, release management, mobile frameworks, and the adoption of AI-assisted and agentic workflows.
- Drive outcome-first, customer-centric execution by structuring work around developer journeys and problem spaces; operate the team's engagement models: InnerSource communities and customer enabling.
- Ensure the reliability and performance of mobile CI/CD pipelines, iOS and Android release management processes, and shared mobile libraries and tooling.
- Define and inspect the related success metrics, including adoption, CI/CD reliability and speed, release health, and developer experience outcomes.
- Collaborate closely with Platform Product Management, other Engineering Enablement pillars, SRE, and product engineering teams to align mobile capabilities with business requirements and drive adoption across business units.
- Champion cross-domain expertise by growing engineers to contribute across their technical domain by leveraging agentic capabilities.
Organization/Team Mission
- Mercari Engineering Principles are a shared understanding that serves as the foundation of engineering beliefs and behavior at Mercari.
- The Engineering Principles are designed to complement the organizational identity (Mercari’s mission, values, and culture) from an engineering viewpoint.
- These principles ultimately help us achieve Mercari’s mission by defining the ideal state we seek to realize in the long term.
- The Mobile Enablement team is a core pillar of Engineering Enablement, responsible for enabling group-wide mobile ecosystems across iOS and Android.
- We drive mobile libraries, frameworks, standards, CI/CD infrastructure, release management, and the adoption of modern development practices, including AI-assisted and agentic workflows.
- Our mission is to make mobile development seamless, automated, and scalable so that product engineering teams can focus on delivering value to users.
- We simplify engineering workflows, reduce repetitive tasks through automation and AI, and enable broader collaboration across teams through InnerSource and community-driven models.
- Mercari is looking for an Engineering Manager to lead the Mobile Enablement team, responsible for the team's organizational health, technical strategy, and execution.
- You will lead a team of senior and principal-level engineers spanning iOS and Android, partnering closely with a dedicated Platform Product Manager.
- You will own the organizational "how": composing teams, shaping execution models, and ensuring your team's work translates into measurable outcomes for product engineering customers across the company.
Unique Challenges
- Leading deep specialists in ambiguity: defining direction, making trade-offs with incomplete information, and reassessing priorities as company needs evolve.
- Success requires building trust, setting clear expectations, and providing growth, not prescribing solutions.
- Driving impact through influence, not authority: adoption mainly depends on alignment and trust, not only mandates.
- Significant time will be spent influencing product teams and stakeholders and building mechanisms that scale beyond the team's direct capacity.
- Navigating the AgentEx shift while maintaining operational stability: keeping release management, CI/CD, and maintenance running reliably while simultaneously investing in the future.
- Modernizing the mobile ecosystem to keep pace with our company’s transformation into an AI-native engineering.
