• Leverage caching and persistence technologies to improve the scalability and responsiveness of content services.
• Make and communicate architectural decisions while navigating ambiguity and balancing competing technical trade-offs.
• Contribute to strong engineering practices through unit and integration testing, code reviews, security improvements, documentation, and maintainability initiatives.
• Mentor other engineers through technical discussions, code reviews, documentation, and direct guidance, helping raise the technical quality of the wider team.

Requirements

• 5+ years of relevant professional software engineering experience, with a track record of delivering production software at meaningful scale.
• Experience with one or more areas such as parser generators, interpreters, language runtimes, compilers, or taking language features through a complete product lifecycle.
• Demonstrated ability to independently lead complex technical projects, make architectural decisions, communicate trade-offs, and deliver outcomes with limited direction.
• Experience designing and maintaining reliable, high-performance software components used by other teams, products, or large user populations.
• Strong software engineering practices, including automated testing, code review, security awareness, and thoughtful architectural decision-making.
• Strong ability to work across organizational and team boundaries, identify technical dependencies, resolve blockers, and bring projects to completion.
• Experience mentoring engineers and helping improve team-wide technical quality through reviews, design discussions, documentation, or direct mentorship.
• Strong written and verbal communication skills, with the ability to work effectively in both synchronous and asynchronous environments.
• Self-motivated and comfortable navigating ambiguity while maintaining ownership and momentum.
• Familiarity with HTML5 specifications and DOM manipulation is a plus.
