Senior JavaScript Engineer – Voice AI Pipelines

Position Summary

At Parker Technology, our customer service representatives and software help real people—motorists stuck at parking garage entries and exits—get moving again. This is not a pure-play B2B SaaS job: you’ll see your code drive microphones, devices, gates, and (most importantly) make a small difference in 5,000+ people’s lives every day.

We’re building our voice AI capabilities to answer and resolve calls autonomously while transferring calls to live agents when the AI can’t cut it. You’ll work with a skilled team to ship production‑grade voice AI services that blend LLMs with sub‑second telephony performance.

What You’ll Do

  • Build Node.js/TypeScript microservices that ingest real-time audio streams and orchestrate ASR/NLU pipelines.
  • Integrate voice AI and LLM services to handle intent, multi-turn dialogs, and escalation to live agents.
  • Optimize for low latency & reliability: caching, circuit breakers, telemetry, and rollbacks.
  • Work closely with other engineers, product, and even field support—expect the occasional trip to a parking garage to see your code in action.
  • Ship fast, iterate often, and continuously improve our AI pipelines.

What You Bring

  • Excitement about voice AI and the idea of building real-time pipelines.
  • Solid experience in JavaScript/TypeScript and Node.js.
  • Experience prompt‑engineering or fine-tuning LLMs and vector search (RAG) workflows.
  • Comfort working with APIs, queues, and event-driven architectures.
  • Curiosity and a growth mindset—you learn fast and like experimenting.
  • Clear, concise communication in Jira tickets, PRs, and cross-team discussions.

Bonus Points

  • Hands‑on work with voice or video pipelines (SIP, WebSockets, WebRTC, Twilio, SignalWire, FreeSWITCH).
  • Familiarity with application monitoring, CI/CD, and IaC setup and processes.

What We Offer

  • Impact you can see—visit a garage and watch your service help a real person exit in seconds.
  • Chance to shape our AI strategy alongside a small, senior engineering team.
  • Competitive salary, 401(k) with match, healthcare, and the normal stuff.
  • Flexible work environment with awesome, easy-going coworkers in downtown Indianapolis.

Our Values

We believe strongly in hiring individuals who align with our six core values:

  • Honesty & Integrity: We build trust through transparent communication, ethical decisions, and accountability
  • Excellence in Communication: Clear, compassionate, and active listening ensures everyone—from teammates to parkers—feels heard and supported
  • Servant’s Heart: We prioritize service to clients, partners, and each other, embodying empathy and stepping in to help, wherever needed
  • Going Above & Beyond: We push past the status quo by experimenting, celebrating results, and embracing challenges—even when it takes us outside our comfort zone
  • Noble Intent: We strive to assume the best in others, fostering trust through empathetic listening and thoughtful collaboration
  • Critical Thinking: We value clarity, curiosity, and creative problem-solving—asking “why,” seeking diverse perspectives, and crafting smart, thoughtful plans
