What they're building

Agent experience for coding agents moderate signal

Today: Models, APIs, and infrastructure in one place.

Roles: Software Engineer, Agent Experience

Requirements mention: MCP server · llms.txt · SDK examples · Claude Code, Cursor, Codex

Inference: the company is putting effort into how coding agents discover and use its API, through docs, samples and an MCP server. This rests on one posting.

Regional go-to-market build-out in Europe moderate signal

Today: Pre-recorded and real-time speech-to-text and voice agent APIs.

Roles: Head of GTM, Europe

Requirements mention: build and lead AssemblyAI's go-to-market business across Europe · data residency · multilingual performance · Voice AI models, Voice Agent API, and LLM Gateway

Inference: the company is setting up a regional sales operation in Europe, starting with a London-based leader for its Voice AI models, Voice Agent API and LLM Gateway. This rests on one posting.

San Francisco sales for digital-native and enterprise accounts moderate signal

Today: Production Voice AI from a single API: models, intelligence, deployment.

Roles: Head of Sales, Digital Native · Enterprise Account Executive · GTM Recruiter

Requirements mention: usage-based or consumption pricing model · product-led, bottoms-up motion · enterprise procurement · security review processes · LLM Gateway · our go-to-market team is growing fast

Inference: the company is adding sales capacity in San Francisco for two motions: digital-native companies buying on usage pricing, and enterprise accounts that go through procurement and security review. The sales postings also name LLM Gateway, which the site text does not describe. This is drawn from two sales postings and a GTM recruiter posting.

Production inference serving at scale strong signal

Today: Transcribe live audio and video files in real time at ultra-low latency and high-quality accuracy.

Roles: Senior Software Engineer, Inference

Requirements mention: inference infrastructure · customer-facing APIs · backend services · SDKs

Inference: the company is hiring for the path from new model capabilities to documented APIs that serve production traffic. The same title is open in the United Kingdom and in North America.

Training and inference systems for the company's speech models weak signal

Today: The Universal-3.5 Pro speech model and speech-to-text APIs.

Roles: Senior Researcher

Requirements mention: large-scale distributed training · streaming inference · JAX, TPUs, Flax, Optax · continuous batching

Not enough roles to infer a next step.

Internal data and automation for finance and revenue operations weak signal

Today: Models, APIs, and infrastructure in one place.

Roles: Finance Engineer · Senior GTM AI Engineer

Requirements mention: warehouse modeling · LLM-based agent workflows · internal tools · scheduled jobs, retries, error handling

Not enough roles to infer a next step.
