What Deepslate is building
Deepslate trains its own speech-to-speech model, Opal, that takes audio in and returns audio out with no text transcript in the middle. The standard voice-agent stack chains three systems (speech-to-text, an LLM, text-to-speech), and every hop adds latency and throws away information: tone, emphasis, hesitation, dialect. Deepslate's architecture is three self-trained parts, a speech encoder, a reasoning core built on an open-weights frontier language model, and a speech decoder, trained end to end. The numbers they lead with: 440ms time-to-first-audio on the Artificial Analysis benchmark (fastest listed as of September 2026), about 250ms from end of sentence in their own measurement, around 85% on Big Bench Audio, and the best error rate for European languages on CoVoST2. Opal covers 27 languages. Tech Funding News notes it is the only European model among the six speech-to-speech systems in those benchmarks. The product is developer-facing: WebRTC, SIP and WebSocket endpoints, Python and Node SDKs, and plugins for LiveKit and Pipecat. It runs on Deutsche Telekom's German cloud, is ISO 27001 certified, and can be self-hosted or deployed air-gapped. Pricing is aggressive: 10 cents a minute list, 2 cents for early builders. Customers in production include insurers, contact centres and platforms, though none are named.
Why this matters
Voice is where the cascaded pipeline hurts most. A 2 to 3 second pause is the difference between a call that feels like a conversation and one where the customer starts talking over the bot, and the founders know this first-hand: their 2023 AI meeting assistant died on exactly that latency problem. For European insurers, banks and public bodies, the other blocker is where the audio goes. Paesler's line is that data sovereignty is a prerequisite, not a nice-to-have, and Deepslate discloses where compute happens. A model that is both the fastest on a public benchmark and deployable on German infrastructure or on-prem removes the two objections that keep regulated European call centres on legacy IVR.

How to actually get hired at Deepslate
Why applying the normal way doesn't work
Deepslate uses an ATS, but referrals still come first. Cold applications aren't ignored — they're just behind referrals, sourced candidates, and recruiter picks.

What to show them
Wire Opal into a real SIP trunk through the LiveKit or Pipecat plugin and build a German-language insurance first-notice-of-loss agent. Record a call, measure end-to-end latency at the phone (not the API), and write up where the milliseconds go: network, jitter buffer, model, barge-in handling.

What Deepslate screens for
42CAP's Julian von Fischer cited the founders' technical depth; Alstin's Andreas Schenk pointed to their history of scaling latency-critical systems before Deepslate. That is a bet on a small team that has already beaten OpenAI and Google on a public latency benchmark, now being funded to sell. The hires that matter next are commercial: people who can walk an insurer's procurement team through on-prem deployment and data residency. With a team under 20 and no public job board, the window is a direct note to the founders that shows you understand regulated European voice deployments.
Don't send a generic CV to Deepslate. Mirror the job posting's language to get past automated screening.
Don't make these mistakes
Calling yourself 'passionate about conversational AI'. Paskal and Jan started programming at 11 and built the first voice chat for Minecraft while running two of Europe's largest Minecraft servers; they've been shipping latency-critical real-time systems for millions of users since they were teenagers. Also don't pitch a cascaded STT-LLM-TTS demo as your proof of work. Their entire thesis is that the cascade is the problem.
Mistakes that kill Deepslate applications
At people, a copy-paste CV is immediately obvious. It's an instant no.
Lead with their problem, not your ambition. Deepslate is focused on Voice is where the cascaded pipeline hurts most — show you understand that.
Don't apply and wait. The median AI application gets no response ever. One follow-up at day five roughly doubles reply rates.
