• Take full-cycle ownership of projects, including coordination, planning, risk management, security and compliance reviews, design, development, testing, rollout, and maintenance; resulting in an improvement of customer, product, and/or business outcomes.
• Make high-quality, impactful technical contributions across the full stack, encompassing light infrastructure work and a full-stack Ruby on Rails monolith.
• Drive collaboration with teammates, partners, and stakeholders to advance team and organizational goals.
