Senior Staff Software Engineer, Core Experiences

• Build Critical Systems

• Own the architecture of key backend and frontend systems within Core Experiences. - Lead the implementation of high-impact components end-to-end. - Ensure systems are scalable, reliable, and observable from day one. - Drive Execution at Scale

• Partner with engineering teams across Warsaw and Redwood City to turn architecture into working systems. - Lead delivery of large, cross-team initiatives with measurable business impact. - Balance speed, quality, and long-term maintainability in real-world tradeoffs. - Set Technical Direction

• Establish patterns, frameworks, and standards that enable teams to move faster. - Translate business priorities into clear technical roadmaps. - Identify risks early and guide teams toward pragmatic solutions. - Enable AI in Engineering

• Enable teams across Core Experiences to apply AI in their day-to-day engineering operations — coding, code review, testing, debugging, documentation, and incident response. - Design and build agents that support the full software development lifecycle (SDLC), from design and implementation through code review, testing, deployment, and operations. - Establish best practices, guardrails, and reusable patterns for safe and effective AI usage in engineering workflows. - Evaluate and integrate AI tooling (e.g., Cursor, Claude Code, internal Box AI capabilities) into the team's standard development workflow. - Measure and continuously improve developer productivity and code quality through AI-driven workflows. - Influence & Mentor

• Collaborate across geographies and functions to align on architecture and execution. - Mentor senior and staff engineers in system design, implementation, and effective use of AI in engineering. - Contribute to a culture of strong ownership, quality, and continuous improvement. - Ship Code

• Be hands-on in prototyping and contributing production-grade code across the stack. What You'll tackle in the first 6-12 months

• Lead the effort to break our backend and frontend out of the monolith into modern, modular, and maintainable architectures. - Drive the organization's adoption of continuous integration and DevOps best practices, raising the bar for build, test, and deployment workflows. - Roll out AI-assisted engineering practices across Core Experiences — enabling teams to use AI in their day-to-day work and embedding it into coding, review, and operational workflows. - Design and ship agents that support the SDLC (e.g., code generation, automated review, test authoring, release readiness, on-call assistance) and demonstrate measurable productivity gains. - Define how we build products going forward — including tooling, workflows, and architectural patterns shared across Warsaw and Redwood City. - Set up frameworks for effective cross-site, cross-functional collaboration between backend and frontend engineers. - Balance rapid delivery with long-term technical investments to ensure Core Experiences scales with enterprise-grade performance, security, and maintainability. Who You Are

• 12+ years of professional software engineering experience across backend and frontend. - 5+ years leading complex, cross-team technical initiatives. - Ability to operate at both high-level architecture and low-level execution. - Proven track record of designing and shipping distributed systems at scale. - Hands-on experience breaking monoliths into service-oriented or modular architectures. - Strong experience driving continuous integration, CD, and DevOps practices across engineering organizations. - Hands-on experience using AI coding tools (e.g., Cursor, Claude Code) and integrating them into team workflows; experience designing or building LLM-powered agents for engineering use cases is a strong plus. - Familiarity with modern AI/agent frameworks, prompt engineering, evaluation, and safe deployment of AI in production engineering workflows. - Experience aligning cross-functional and cross-site stakeholders around architecture decisions. - Pragmatic decision-making: you balance ideal design with real-world constraints. - Passionate about mentoring and building a strong engineering culture. - BS/MS/PhD in Computer Science, Engineering, or equivalent experience. - Comfortable working in a hybrid, globally distributed environment; able to travel to the U.S. at least twice a year for team off-sites.
