We are looking for a Senior Software Engineer with 5+ years of experience to join a small, high-impact engineering team building AI-powered voice agents that handle millions of calls monthly for Fortune 500 companies. You will work across product teams, including core product and forward-deployed engineering, shipping full-stack features that power an LLM-based conversational AI platform.
This is a Series B AI company building autonomous contact center technology: AI that answers calls, routes work between AI agents and humans, and manages conversations end to end. The company is fully remote across the United States and Canada, lean by design, and focused on shipping real AI products at enterprise scale rather than AI as a marketing layer.
What you will be doing:
Build and ship full-stack product features that support and enhance LLM-powered voice and chat products.
Work across product teams to deliver capabilities that help win deals and scale the platform, including forward-deployed engineering work.
Integrate speech recognition, text-to-speech, and conversational AI model improvements into production systems.
Optimize and debug production systems balancing latency, cost, and user experience at enterprise scale.
Collaborate closely with product and ML teams in a fast-moving startup environment where every engineer owns multiple initiatives.
Base salary range of $130K - $190K USD depending on level (Senior 1 vs Senior 2) and location, plus competitive equity. Fully remote in the US or Canada, with team and company offsites approximately every six weeks. Visa transfers only (no new sponsorship).
- 5-8 years of experience as a full-stack software engineer
- Proficiency in Python or TypeScript (hard requirement: one or the other)
- Hands-on experience working with LLMs (multi-turn agents, prompt engineering, or tools like LangChain), not just theoretical knowledge
- Full-stack engineering experience shipping solutions at scale in a startup or high-growth environment
- Experience owning and shipping software solutions that scale to millions of users
- Familiarity with relational databases (MySQL, PostgreSQL), cloud environments (AWS, GCP, or Azure), and CI/CD pipelines
- Experience with conversational AI, multi-turn agents, or LangChain
- Startup mentality: self-starter who owns outcomes end to end
- Located in the United States or Canada with valid US or Canada work authorization (visa transfers only, no new sponsorship)
- Preferred: experience in DevEx, SRE, or platform engineering
- Preferred: experience at telephony or contact center software companies
- Competitive equity
- 100% medical, dental, and vision coverage
- Flexible vacation policy
- Tech and learning stipend
- Paid sabbatical after 5 years
- Fully remote (US or Canada)
