Lead - Software Engineer

On AG Vacant since : 11.11.2026 Number of jobs : 1 8005 Zürich (ZH) 100% Immediately Permanent

In Short

Based in our Zurich office, this role serves as the technical anchor for frontend engineering within a dedicated cross-functional incubator spanning product, design, strategy, and engineering. The position charts technical direction across web and mobile platforms without relying on predefined roadmaps, balancing hands-on craft with architectural leadership to build the foundations of next-generation digital experiences. Reporting directly to the Engineering Director, this role drives the evolution of our digital landscape from early ideation through to resilient, production-grade systems.

Your Mission

• Lead Technical Strategy & Autonomous Execution - Own web and mobile frontend architecture for our primary innovation platform. Navigate ambiguity independently, break down complex, multi-faceted spaces into transparent milestones, and deliver end-to-end initiatives with high autonomy.
• Champion Technical Excellence & Mentorship - Guide and mentor engineers within a cross-functional environment. Cultivate an inclusive engineering culture centered on candid feedback, co-create architectural decisions, and elevate team capability through modern workflows, tooling, and emerging paradigms such as AI coding agents and Model Context Protocol (MCP).
• Drive Cross-Team Alignment & Innovation - Steer impactful technical initiatives that align platform deliverables with wider organizational goals. Partner with sister engineering groups, operational stakeholders, and leadership to share reusable patterns, learnings, and architectural frameworks.
• Co-Create with Cross-Functional Partners - Partner closely with Product, Design, and Strategy to evaluate technical feasibility, prioritize high-impact experiments, and shape the product roadmap from discovery to scalable release.
• Raise Architectural & Operational Standards - Define benchmarks for system design, code health, accessibility, and performance. Direct the technical transition of legacy frameworks (e.g., Flutter to modern React / Next.js architecture) while ensuring high uptime, robust observability, and platform resilience.

Your Story

• A solid academic foundation in Computer Science, Software Engineering, or equivalent practical industry experience.
• Proven experience (typically 6+ years) designing, deploying, and supporting production-scale web and mobile applications, backed by strong expertise in system architecture.
• Demonstrated track record navigating fast-moving environments (such as tech incubators, high-growth scale-ups, or rapid-iteration product squads) with autonomous problem-solving.
• Deep knowledge of modern multi-platform web and mobile technologies (e.g., TypeScript, modern React, Flutter, Swift, or Kotlin), alongside a clear, pragmatic perspective on architectural trade-offs.
• Direct experience guiding platforms through significant architectural shifts and refactoring initiatives (such as Flutter to React) with zero downtime and controlled dependencies.
• A blend of refined visual craft-delivering precise UI/UX details-with rigorous engineering standards around modularity, accessibility, and speed.
• Broad familiarity with modern API federation (e.g., GraphQL / Apollo Federation) and emerging agentic protocols (such as MCP).
• A collaborative mindset dedicated to elevating peers through active mentorship, transparent technical critique, and inclusive team-building.
• Fluency in English with strong interpersonal and technical communication skills.
