About the role

Applied AI Engineers are the technical half of every deal at AssemblyAI. You'll partner with two Digital Native Account Executives and own the technical side of their book: from the first conversation with customers, to helping them win technical evaluations, to driving successful technical implementations.

Our digital native customers are the fastest-growing AI companies building with voice: voice agents, AI notetakers, dictation, and conversation intelligence. They move fast and test on their own, so speed matters at every step.

This is pre-sales engineering, but far more hands-on than a typical SE role. You'll write code for customers, build MVPs, debug their integrations, tune our models on their real audio, and do whatever it takes to make sure customers have successful implementations. Your AE owns the business case and the commercials. You own the developer and the technical work, and together you make customers happy and get them scaled up.

What you'll do

Customer-facing technical work

• Join early, often on the first call, and become the developer's direct line to AssemblyAI in a shared communication channel (often Slack)
• Help our customers evaluate and test our products: get their success criteria up front, help them design fair benchmarks, and catch mistakes (wrong model, bad truth files, misconfigured streams) early
• Tweak configurations and help customers design robust implementations for their unique use cases
• Build demos, prototypes, and proofs of concept in the customer's stack
• Debug customer code and production issues across our streaming and async APIs
• Stay close to the customer, earn their technical trust, and deliver first-class service that turns them into champions
• Work collaboratively with your AEs on every account
• Meet customers in person, including flying around the world to work with them onsite
• Stay with the customer through production rollout, then hand off cleanly to our post-sale Forward Deployed Engineers

Product and roadmap influence

• Influence our roadmap by bringing what you hear from customers to Product, Research, and Engineering, and test new models and features before customers see them
• Turn customer issues into reproducible cases for Research and Engineering, and track patterns across accounts
• Contribute to docs, guides, and example code that help developers integrate faster

Community and events

• Represent AssemblyAI at Voice AI meetups, conferences, and customer events
• Build developer-facing resources that are shared publicly

What you'll need

• A strong technical foundation: an engineering degree, a coding bootcamp, a software engineering role, or a sales or solutions engineering role
• Strong programming skills in Python and/or TypeScript/JavaScript, and the ability to read and debug code in other languages
• Excellent written and verbal communication; you'll write customer Slack messages, emails, and technical guides every day
• Experience with web APIs, WebSockets, and real-time data streaming
• An understanding of audio fundamentals (sample rates, encodings, codecs), or the drive to learn them quickly
• Fluency with AI tools like Claude or Cursor to prototype, debug, and solve problems fast
• A high sense of urgency and persistence
• Comfort with ambiguity and context-switching: you can take a vague problem, figure out what matters, and drive it to resolution, while keeping many customers and priorities moving at once
• Must be based in San Francisco, London, or New York City, with an expectation of 3 days a week in-office attendance, and willing to travel roughly 10–25% of the time for customer visits, events, and team offsites

Nice to have

• Experience at a startup or API-first company
• Customer-facing experience as a solutions engineer, sales engineer, or developer advocate
• Hands-on work with voice agent frameworks (LiveKit, Pipecat) or speech models
• Public speaking or community involvement
