Senior AI Engineer role focusing on building a voice-first AI agent enabling natural spoken interactions and real-time actions.

О компании

We are looking for a Senior AI Engineer to join a product team building a voice-first AI agent that allows users to interact through natural spoken conversations. The agent reasons, uses tools, and takes actions in real time, with the product currently in active development and its architecture and product direction still evolving.
This is a hands-on engineering role covering the full voice-agent stack, from real-time communication and speech processing to agent orchestration, tool use, memory, and backend integrations. You will have significant influence over both the technical architecture and product decisions, working closely with product, design, and a small engineering team.

Требования

proven track record of shipping GenAI and agentic systems to production that are used by real users,
hands-on experience with LangGraph , including designing and running production workflows,
strong Python skills, including asynchronous programming and building production services such as FastAPI applications,
strong software engineering and system architecture skills, with the ability to design systems end to end and make informed technical trade-offs,
senior or lead-level engineering experience with ownership of significant technical decisions,
strong product sense and evidence of influencing what gets built, not only how it is implemented,
strong understanding of production-quality software development, testing, observability, and reliability,
fluent English with the ability to communicate clearly with both technical and non-technical stakeholders,
willingness to participate in regular in-person team sessions.
Practical experience using AI-powered assistants (e.g. Claude Code, GitHub Copilot, Cursor) to improve productivity, quality, or decision-making in software delivery.
Work from the European Union region and a work permit are required. Strongly preferred: hands-on experience building voice agents or real-time voice pipelines ,
experience with Pipecat, LiveKit Agents, or similar voice-agent frameworks ,
practical experience with streaming STT/TTS technologies such as Deepgram, Soniox, ElevenLabs, or Cartesia,
experience with voice activity detection, turn-taking, interruption handling, and voice latency optimization,
production experience with WebRTC and/or LiveKit ,
experience with telephony technologies such as Twilio, Telnyx, or SIP.

Будет плюсом

experience with LLM evaluation and observability tooling such as Langfuse, LangSmith, or custom evaluation frameworks,
experience working with multiple model providers such as OpenAI, Anthropic, and Gemini,
experience routing between models based on cost, latency, and capability,
experience with MCP or similar tool-integration patterns,
enough TypeScript and React experience to contribute to the client-side voice interface,
experience working in a startup or 0-to-1 product environment.
Experience applying GenAI in a more structured way within the SDLC, including defined workflows, prompt patterns, or tool integrations embedded into daily work.
Interest in and familiarity with emerging AI-driven practices (e.g. agent-based workflows, automation patterns, AI-augmented development), with a willingness to explore and experiment beyond standard approaches.

measuring and reducing end-to-end latency across the voice and agent pipeline,
ensuring reliable voice interactions under real-world network conditions.
shaping the overall system architecture and making build-vs-buy decisions for models, speech technologies, and other components,
building evaluation into the development workflow through conversation-level test sets, regression suites, LLM-as-judge approaches, and latency and quality metrics,
implementing observability and tracing using tools such as Langfuse, LangSmith, or similar solutions,
diagnosing production issues through traces, metrics, and real user sessions,
applying strong engineering practices including code reviews, automated testing, CI/CD, documentation, and maintainable design.
translating user needs and product goals into practical technical proposals,
challenging assumptions and suggesting alternative approaches when they can improve the user experience,
prototyping ideas quickly and hardening successful approaches for production,
communicating technical trade-offs clearly to both technical and non-technical stakeholders,
contributing to regular in-person team sessions for planning, design, and technical reviews.
working remotely from Europe, ideally within 1–2 hours of CET,
participating in in-person team meetings every 4–6 weeks,
being open to collocating in Berlin, with Madrid or Barcelona also possible alternatives.
