Member of Technical Staff (Envoy Response)

• At Envoy, the Response team builds technology that helps organizations protect their people, stay ahead of emerging threats, and communicate effectively during critical situations
• We’re solving complex, real-world problems where reliability, speed, and intelligent decision-making matter
• As a Senior Fullstack Engineer on the Response team, you’ll work on some of Envoy’s most technically challenging and impactful products
• You’ll help build and scale our Threat Intelligence platform, which processes large volumes of real-time signals from thousands of sources, uses AI to identify and enrich relevant threats, and helps organizations understand potential risks to their people and workplaces
• You’ll tackle challenging engineering problems involving distributed systems, real-time data pipelines, geospatial intelligence, and AI-powered decision-making
• You’ll also build our Emergency Notifications platform, enabling organizations to communicate critical information to employees and visitors quickly and reliably across multiple channels when it matters most
• These are systems where performance, scalability, and reliability have a direct impact on people’s safety
• This is a backend-focused fullstack role
• You’ll spend much of your time designing scalable services, building distributed systems, and solving complex backend challenges, while also owning customer-facing experiences using React
• We’re looking for engineers with strong backend fundamentals who are comfortable moving across the stack and taking end-to-end ownership of the products they build
• You’ll have the opportunity to influence technical architecture, apply AI to meaningful product problems, and work closely with Product, Design, and Engineering to bring ambitious ideas to life
• This on-site position requires 4 days a week (Monday through Thursday) in our San Francisco HQ office
• Build and scale real-time threat intelligence systems that ingest, process, classify, and enrich signals from numerous data sources to surface actionable threats to organizations
• Solve challenging distributed systems problems, including high-throughput event processing, data deduplication, and reliable asynchronous workflows
• Apply AI to real-world engineering problems, building intelligent workflows that help identify relevant threats, reduce noise, and deliver actionable insights
• Build and evolve emergency notification systems that deliver critical communications reliably and at scale across channels such as SMS, email, mobile push, and Slack
• Design, build, and operate scalable backend services, APIs, and data models using technologies such as Kotlin, Kafka, Postgres, AWS, and OpenSearch
• Build intuitive, performant customer-facing experiences using React and TypeScript, taking ownership of features across the full stack
• Drive technical design and architecture decisions, balancing scalability, reliability, performance, and engineering simplicity
• Own features and systems end-to-end, from technical design and implementation to production operations, monitoring, and continuous improvement
• Partner closely with Product, Design, and other Engineering teams to translate complex customer problems into simple, effective solutions
• Raise the engineering bar through thoughtful code reviews, technical mentorship, and improvements to engineering practices
