Staff Software Engineer, Snap Inc.

• Experience designing, building, and operating backend services or distributed systems at significant scale
• Proven track record of owning highly-available, mission‑critical systems, including on‑call participation, incident response, and driving systemic fixes
• Ability to set technical vision and lead complex, cross‑functional initiatives over multiple quarters, balancing architectural quality, reliability, and product velocity
• Strong foundation in system design (APIs, data models, storage, pub/sub, queues, and workflow orchestration) and performance/latency optimization
• Deep experience with observability (metrics, logging, tracing, dashboards) and using data to debug, harden, and evolve large-scale systems
• Excellent collaboration and communication skills; able to work effectively with Product, DS, ML, Design, and other engineering teams to align on requirements and trade‑offs
• Ability to mentor and uplevel engineers, provide clear technical guidance, and create structures that make the team more effective over time
• Bachelor’s degree in a technical field such as Computer Science, or equivalent practical experience
• 9+ years of software development experience; or Master’s degree with 8+ years of experience; or PhD with 5+ years of experience
• Experience acting as a technical lead, domain expert, or owner of complex technical initiatives
• Experience building backend systems or distributed systems in production environments

Desirable

• Platform Engineering builds the tools, frameworks, and internal platforms that help engineers at Snap develop high-quality software in a fast development cycle, with a strong focus on quality, developer productivity, and operational excellence
• In this role, you’ll help build the next generation of AI-powered testing tools and infrastructure across Snapchat’s mobile apps and multi-cloud backend services, including agent harnesses, evaluation systems, Temporal-based workflows, and telemetry-driven debugging capabilities. You’ll work across teams to turn product and engineering needs into scalable platforms that reduce manual work, surface regressions earlier in CI/CD, and make it easier for engineers to ship reliable software faster
• Build and own agent harnesses and testing infrastructure—tool design, prompt engineering, context management, and output evaluation—to drive functional and load testing across Snapchat's mobile apps and multi-cloud backend services
• Push AI-native engineering practices across the team: writing reusable skills, standing up looped and scheduled agents, building MCP tools, and offloading ops work (deploys, log triage, JIRA updates) to agents instead of doing it by hand
• Architect Temporal-based workflows and services that speed up detection of bugs and regressions in the CI/CD pipeline, applying async Python, workflow determinism constraints, and typed dataclass-driven design
• Build the telemetry and evaluation layer that makes agent behavior measurable—writing non-trivial BigQuery SQL, reasoning about mobile telemetry (Blizzard-style events, client vs. server timestamps, sampling), and turning raw logs into actionable hypotheses
• Work across teams to understand product requirements, evaluate trade-offs, and deliver the solutions needed to ship innovative products
• Advocate for and apply best practices around availability, scalability, operational excellence, and cost management
• Be part of a passionate team building the next generation of Snapchat's AI-powered testing tools and infrastructure
