## About the Role

* Internal Tooling Track Record: You've built and owned tooling or automation that other engineers depended on day to day, and you understand that adoption is part of the job, not a follow-up;
 * Email & Template Engineering: You can deliver production-ready email independently with a templating language, and you understand why email engineering is not web engineering - the rendering constraints, the client quirks, the testing burden.
 * AI Expertise: You're a forefront user of Agentic AI. You're able to bring hands on experience and start influencing the team beyond code generation; reserving judgment for architecture, business logic, and security, using AI as a thought partner and able to set up quality gates and safety nets to enhance existing engineering workflows and propose AI-native alternatives.
 * Scalable Systems & Architecture: Experience designing and evolving large-scale web applications, including well-designed APIs, distributed systems, high-volume data flows, and scalable architectural patterns. Ability to make sound technical trade-offs that balance short-term delivery with long-term sustainability;
 * Technical Leadership: Demonstrated ability to influence technical decisions, drive engineering best practices, and contribute to architectural direction within your team;
 * Product & Business Impact: Strong product mindset with the ability to translate ambiguous business challenges into scalable technical solutions, using experimentation, data, and customer insights to guide decisions;
 * Proactive Problem-Solving: Comfortable navigating ambiguity and independently solving complex technical and product challenges, while knowing when to engage others to maximize impact;
 * Ownership & Accountability: High level of self-organization, ownership, and responsibility, with a track record of driving initiatives from concept through delivery and measurable outcomes;
 * Collaboration & Communication: Excellent collaboration, stakeholder management, and communication skills, with the ability to work effectively across engineering, product, design, and data functions. English level B2 or higher;
 * Engineering Excellence: Experience working in a cross functional team, contributing to code and design reviews, and helping raise the engineering bar through knowledge sharing and technical leadership;
 * Operational Excellence: Understanding of observability, reliability, monitoring, and operational best practices, with willingness to participate in your squad's on-call rotation (1 week every 5 weeks)
