Job Description:

Great customer support requires human agents and AI in perfect balance, and Assembled is the only unified platform that orchestrates both at scale. Companies like Canva, Etsy, and Robinhood use Assembled to coordinate their entire support operation — in-house agents, BPOs, and AI — in a single operating system. With AI Agents that resolve cases end-to-end, AI Copilot for agent assistance, and AI-powered workforce management that optimizes both human and AI capacity, Assembled helps teams deliver faster, better service while making smarter decisions about how to staff and automate. Backed by $70M from NEA, Emergence Capital, and Stripe, we're building the platform that makes AI and human collaboration actually work.

Job Responsibility:

  • Build foundational voice features: Develop voice-specific product features from the ground up, such as implementing voice recognition capabilities powered by LLMs and intelligent categorization of incoming calls
  • Improve LLM model results for voice applications: Enhance our voice recognition and generation engine using advanced techniques
  • Develop voice AI infrastructure: Architect the abstractions that enable integration of various types of LLMs tailored for voice applications
  • Engage with customers: Collaborate with our customers (both support agents and managers) to understand how they interact with our voice product, and how we can improve their experience
  • Wear many hats: Be versatile in roles — coding, user research, planning, brainstorming, and cross-team collaboration
  • Shape the team culture: Encourage a startup mentality focused on product quality and taking initiative

Requirements:

  • 3+ years of experience in software engineering as an individual contributor
  • Strong proficiency in a modern programming language (Go, Python, C#, etc.)
  • Experience with distributed systems
  • Solid understanding of data structures, algorithms, and software design principles
  • Ownership mindset and proven track record of learning new technologies quickly
  • Enthusiasm and passion for learning AI/ML technologies (no prior experience required)
  • Highly ambitious and driven, setting high goals for yourself and others
  • Put customers first, focusing on solving real problems
  • Enjoy fast-paced environments and can quickly adjust when new insights emerge
  • A bit of a maverick streak that helps you come up with creative solutions
  • Have made a noticeable impact on small teams and have solid experience in startups or smaller companies
  • Stay humble and open to feedback, value teamwork, and are always ready to learn and grow
What we offer:
  • Generous medical, dental, and vision benefits
  • Paid company holidays, sick time, and unlimited time off
  • Monthly credits to spend on each: professional development, general wellness, Assembled customers, and commuting
  • Paid parental leave
  • Hybrid work model with catered lunches everyday (M-F), snacks, and beverages in our SF & NY offices
  • 401(k) plan enrollment
  • Stock options
