You should apply if you are deeply technical, love staying close to the code, and thrive when given absolute ownership of problems. Experienced: You have 7+ years of experience (with a track record of leading technical direction) and have built up enough scar tissue to inherently know which technical decisions matter and which don't. Product Minded: You care deeply about metrics, users, and data. You don't just build what is asked; you define what matters in a domain and set meaningful metrics to measure success. A Natural Leader: You lead by example and through influence. You enjoy mentoring other engineers, driving alignment on complex architectural shifts, and shipping high-quality results. AI & Data Enthusiast: You are excited to engineer how we feed context to AI models (storing, fetching, and selecting standards) and want to design how unstructured data seamlessly flows through a reliable, enterprise-grade system.

You've contributed to technical decision-making: architecture reviews, design documents, or ADRs that had real consequences. You've led knowledge-sharing sessions or mentored engineers who are better for it. Competency profile: Systems Thinking: You understand how components interact in distributed systems. You design for failure scenarios, not just the happy path. Ownership & Accountability: You take end-to-end responsibility. When something is broken or missing, you raise it and fix it - you don't wait for the ticket. Pragmatic Problem-Solving: You balance ideal solutions with practical constraints. You know when to move the architecture forward and when to ship. Collaboration & Influence: You shape technical decisions through quality of argument, not seniority. You can disagree and commit - and you know when to do which. AI-Readiness: You think about AI strategically, not just tactically. You've embedded AI-driven automation into production systems, can evaluate where it adds real leverage versus where it creates noise, and actively help the team develop this fluency. Continuous Learning: You stay current, experiment, and adapt. You optimize for the codebase 2 years from now, not just the sprint. Quality Mindset: You build maintainable, secure, well-tested services. You document, you mentor, you leave things better than you found them.
