Staff Software Engineer, Healthcare — Customer Experience

Zipline is hiring a Staff Software Engineer on its Nest Applications team to shape the customer experience of software used to order, track, and manage healthcare deliveries. The role leads end-to-end development of customer-facing applications and improves how the team designs, tests, launches, and iterates on those products.

Responsibilities:

• Lead the design and delivery of customer-facing applications that support ordering, tracking, and delivery operations
• Own major projects end to end: shaping user flows, making UX decisions, designing architecture and data models, implementing across the stack, and measuring results after launch
• Build fast feedback loops with customers through direct conversations, analytics, support signals, limited releases, and structured experiments
• Establish feature-flag, beta, phased-rollout, or other gradual-release practices that let us validate changes with a subset of customers before broad release
• Raise the quality bar for frontend UX, interaction patterns, accessibility, and product polish
• Partner with operations, supply chain, finance, and customer-facing teams to identify and solve high-impact user problems
• Improve reliability, testing, observability, and engineering practices across the applications you own
• Mentor engineers and help set product-minded technical standards across the team

Requirements:

• 10+ years of production software engineering experience, including staff-level technical scope
• Deep full-stack experience, including modern frontend development with React or a comparable framework and strong backend capability in Go, Python, or a similar language
• A strong record of building external customer-facing products where UX affects adoption, trust, and business outcomes
• Demonstrated customer obsession: you seek feedback, speak directly with users, turn insight into product improvements, and advocate for customer needs
• Strong independent design and UX judgment; you can make high-quality product decisions without relying on a dedicated designer
• Experience with limited releases, feature flags, beta programs, experiments, or phased rollouts
• A record of owning architecture across teams, mentoring engineers, and leading delivery in an ambiguous, fast-changing environment
• Experience in both a rigorous, high-engineering-bar organization and a startup or scale-up environment where you built through ambiguity
• Clear, effective English communication
• E-commerce, marketplaces, or other high-expectation external customer experiences
• Measurable improvements to conversion, activation, retention, customer satisfaction, or usability
• Healthcare, fulfillment, logistics, warehouse-management, or supply-chain products
