Senior Fullstack Engineer
Senior Fullstack Engineer building end-to-end marketplace commerce features at Snowflake, owning React UIs for checkout/billing and backend services for transactions, metering, invoicing, and payments. Requires 5+ years experience, strong React and backend (Java/Python/Go) skills, and transactional systems background.
About the job
Responsibilities
- Build and own end-to-end full-stack features — from polished React-based checkout and billing UIs to the backend services that process, validate, and settle marketplace transactions at scale.
- Design and implement robust backend APIs and services in Java or Python that handle the lifecycle of commercial transactions: entitlements, metering, invoicing, and payment orchestration.
- Develop reusable, accessible React component libraries and frontend systems that give buyers and sellers clear visibility into usage, spend, and revenue — working closely with design to deliver intuitive experiences.
- Contribute to the reliability, correctness, and observability of high-stakes transactional pipelines — including fraud prevention, idempotency guarantees, and audit logging.
- Collaborate with product, operations, and Billing teams to model and evolve the data schemas and APIs that underpin Snowflake’s Marketplace.
- Participate actively in code reviews, architecture discussions, and sprint planning; raise the bar for engineering quality across the Monetization team.
- Identify gaps in test coverage, monitoring, and operational tooling for transactional workflows and drive improvements proactively.
Requirements
- 5+ years of professional software engineering experience with a track record of shipping customer-facing features on production systems.
- Strong React proficiency — experience building complex, stateful UIs with component composition, hooks, state management (Redux, Zustand, or equivalent), and attention to performance and accessibility.
- Solid backend engineering skills in Java, Python, or Go — including REST/gRPC API design, relational database modeling, and experience with distributed systems or microservices.
- Hands-on experience building or maintaining transactional systems — payment processing, billing pipelines, order management, entitlements, or equivalent commerce/fintech domain.
- Comfort owning full-stack features independently: writing specs, implementing across layers, writing tests, and driving to production.
- Strong collaboration and communication skills — ability to work effectively across engineering, product, and cross-functional partners in a fast-paced environment.
- BS/MS in Computer Science, Software Engineering, or equivalent experience.
Nice-to-Haves
- Experience shipping 0 -> 1 products.
- Familiarity with AI Coding Tools such as Claude, Cursor or similar tool.
- Familiarity with Snowflake's platform — data sharing, Snowpark, or the Data Cloud ecosystem.
- Experience with TypeScript, GraphQL, or modern frontend testing frameworks (Cypress, Playwright, Vitest).
