What you'll do

• Own technical delivery: Drive the design, architecture and implementation of core initiatives, platform services and front-end applications using Kotlin, Java, TypeScript and React.js.
• Align team and vision: Translate product goals into technical direction, ensuring engineers are focused, supported and working toward the same outcomes.
• Lead by example: Stay hands-on, write production-grade code, and foster a high standard of engineering practice across the team. You need to be one of the strongest players on the field.
• Shape architecture: Guide technical decision-making and architectural evolution, balancing trade-offs between pragmatism and long-term quality.
• Mentor and grow others: Support engineers through code reviews, design workshops, and one-to-one mentorship.
• Bridge technical and non-technical: Work with product, design, and operations stakeholders to align technical feasibility with business outcomes.
• Champion DevOps and delivery: Guide infrastructure evolution using AWS, Terraform, and CI/CD best practices for smooth, resilient delivery.

• A strategic and impactful role in a growing international company.
• Competitive salary based on your experience and skills.
• Flexible hybrid working with offices in Vienna, London and Munich.
• The latest tech to support your work, including the newest MacBook Pro.
• Regular in-person events at our London HQ and across the EU.
• The chance to shape a platform used by major global brands and help define what great insurance looks like for the digital age.
• We don't just want someone who can code, we want someone who can lead. If you believe in empowering teams, crafting clean systems, and building products that customers love, we'd love to hear from you.
