Sr. Staff Software Engineer, iOS Search and Shopping Journeys

What you’ll do

• Own and drive the multi-platform product and front-end strategy for Pinterest Search across iOS, Android, and Web, ensuring a cohesive and delightful experience across Text Search, Visual Search, and Image Search.
• Lead the design, implementation, and productionization of end-to-end features and journeys in Search, partnering with product, design, and ML teams to deliver measurable improvements in engagement and quality.
• Use AI (including LLMs and other generative techniques) to accelerate exploration and iteration - rapidly prototyping new interaction patterns, drafts of UI/UX variations, and experiment plans - while applying strong engineering judgment and verification to ensure correctness, performance, and quality.
• Provide technical leadership across 35+ engineers working on Search front-ends and related product surfaces: define architectural direction, codify best practices, and raise the bar on code quality, performance, and reliability.
• Collaborate closely with infrastructure, ML, and back-end teams to design robust APIs, data contracts, and experimentation hooks that enable fast, safe iteration on Search experiences.
• Partner with cross-functional teams across Pinterest to identify technologies being developed elsewhere (e.g., new UI systems, ML-driven components, experimentation platforms) and apply them to Search - or extend Search innovations to other teams where they can have outsized impact.
• Mentor and grow engineers and technical leaders in the organization, helping them develop strong front-end, full-stack, and product-thinking skills.

What we’re looking for

• 10+ years of experience building and shipping large-scale, consumer-facing products, with deep expertise in iOS development and/or strong full-stack engineering skills.
• Demonstrated experience leading front-end and product strategy across multiple platforms (iOS, Android, Web), including designing architectures that support consistency, performance, and fast iteration.
• Strong track record of tech-leading complex, cross-team initiatives from problem definition through execution, using A/B experimentation and data to guide decisions and demonstrate impact.
• Experience collaborating with ML, infra, and back-end teams on API design, data flows, and experimentation frameworks that support rich search or discovery experiences.
• Demonstrated ability to use AI to improve speed and quality in your workflow (e.g., drafting prototypes, exploring alternative UX flows, synthesizing experiment outcomes), combined with a rigorous approach to validating AI-assisted work through testing, data validation, and peer review.
• Excellent communication and collaboration skills, with the ability to influence senior stakeholders and cross-functional partners and align them around a cohesive Search product and front-end vision.
• Bachelor’s/Master’s degree in Computer Science, a related technical field, or equivalent practical experience.
