About the role

  • This role is part of a foundational team working at the intersection of backend systems, real-time voice infrastructure, and applied AI.
  • We're looking for engineers who get excited about greenfield architecture, who want to make early decisions that shape how a product scales, and who thrive when there's more whiteboard than runbook.
  • This is a backend-first role with opportunities to work across the stack when it adds value.

Responsibilities

  • Design and build backend services and APIs from scratch using TypeScript / Node.js
  • Build real-time voice systems: SIP/RTP media handling and STT/TTS pipelines with strict latency requirements
  • Build systems that operate in real-time, high-availability voice environments
  • Work with data stores and event streams, and manage deployments using Docker and Kubernetes (AWS)
  • Collaborate with a distributed team (Seattle and Europe) with async-first norms
  • Strong fundamentals in backend architecture, API design, and data-driven systems
  • We're building a team with diverse perspectives, identities, and professional experiences.
  • We evaluate candidates through a business lens and believe that diversity and unique viewpoints make our company stronger, more dynamic, and a great place to build a career.
  • We create a culture of support and empowerment that challenges the status quo, resulting in an energized team that's passionate about their work.

Requirements

  • 3+ years of professional software engineering experience
  • demonstrated ability to work meaningfully in other languages
  • Experience with Node.js backend development and modern web service patterns (REST APIs, async processing, event-driven systems)
  • Familiarity with DevOps basics: containers (Docker), deployment workflows, and reading infrastructure configs (Terraform, Helm, or similar)
  • Ability to work across Android or iOS code - you don't need to be a mobile specialist, but you can navigate a Kotlin or Swift codebase and make focused changes
  • We work with a high degree of transparency and autonomy.

Nice to have

  • Make foundational architecture decisions that will shape the platform for years to come
  • 4+ years of professional experience as a backend or backend-leaning full-stack engineer
  • Experience working with cloud infrastructure and CI/CD pipelines
  • Comfort with ambiguity-you know how to make good decisions without a playbook
  • Interest in applied AI, voice technology, or telephony (direct experience a plus, not required)
  • Excellent communication and self-organization skills
  • Carrier or B2B platform context
  • Experience with Databricks, Kafka, or streaming data pipelines

Skills

  • Voice is the most human form of communication, yet it's become one of the least trusted.
  • Spam, scams, and AI manipulation have eroded what was once a simple way to connect.
  • Each month our AI voice technology analyzes 28+ billion calls, protecting over 550 million users and 800+ businesses worldwide.
  • This is a pivotal moment for voice.
  • As new threats and technologies accelerate, so does demand for trusted voice communication.
  • Hiya is growing 40%+ year over year, expanding globally, and defining what voice becomes next.
  • You won't just work on what voice is today, you'll shape what it becomes tomorrow:
  • smarter, safer, and genuinely worth answering again.

Compensation

  • Compensation is determined by role scope, skills, experience, location, and market data.
  • $113,000-$197,000
  • We've been recognized by Built In, GeekWire, Comparably, G2, Forbes, and Deloitte Technology Fast 500 for our culture, innovation, leadership, compensation, and more.

Benefits

  • Medical, dental, and vision (PPO & HDHP); 50% dependent coverage
  • Health, flexible spending, and dependent care accounts
  • Life, AD&D, and accident coverage, with company-paid life and long-term disability
  • Flexible vacation policy and paid company holidays
  • Paid parental leave
  • Work-from-home equipment stipend
  • $1,000 annually to invest in your learning and growth
