Vacant job

This role sits at the intersection of Generative AI and Real-Time Audio Processing. You will be a lead builder in our AI evolution, designing agents that don't just "chat," but reason, plan, and act. You’ll collaborate with a passionate cross-functional team to push the boundaries of automated telephony and personalized engagement.

• Architect Autonomous Agents: Build sophisticated agents using frameworks like Google ADK and OpenAI Agents SDK capable of tool-calling and multi-step reasoning.

• Master the Voice Stack: Implement and optimize real-time Voice AI pipelines integrating STT and TTS engines (e.g., Deepgram, ElevenLabs, Whisper).

• Solve for "The Latency Gap": Engineer high-performance solutions to minimize delay, ensuring human-like conversational fluidity in voice interactions.

• Build the Infrastructure: Develop robust backend orchestration in Python and TypeScript, leveraging RAG to ground agents in business data.

• Deploy at Scale: Use Terraform and AWS to manage AI/ML infrastructure, ensuring our "brains" are as reliable as they are smart.

• Iterate with Data: Design and maintain rigorous evaluation suites to measure agent performance and conversational accuracy.

• An AI Specialist: You have a Bachelor’s in CS or AI/ML and 3+ years of professional experience in software or ML engineering.

• A "Builder" Mentality: You enjoy moving from a research paper to a production-ready feature.

• Technically Polyglot: Proficient in Python, with a strong preference for experience in TypeScript/Node.js.

• Data-Driven: You understand that an LLM is only as good as its grounding and its evaluation metrics.

• Experience with WebSocket streams and real-time audio buffer handling.

• Familiarity with VOIP/SIP stacks (Asterisk, Kamailio).

• A foundation in Digital Signal Processing (DSP).

• Hands-on experience with containerized AI service deployment.

Each team has clear responsibilities and goals and the freedom to collaborate on the optimal design for the products and solutions we build. We want to hear your opinion!

We have an agile approach to processes and teamwork and we constantly evaluate and adapt. Our Product and UX teams are closely integrated with development. We use modern frameworks and the best tools available.

We work flexibly and have fun at work. Delivering customer value is as important as the wellbeing of our friends and colleagues. We value personal growth and encourage learning, and embrace every opportunity to share knowledge in the team.

Our roots are in Sweden, but our reach is international. This role is based in our Uppsala office, working in a hybrid capacity. We embrace flexible "business hours" because we know that life doesn't always fit into a 9-to-5 box.

What makes Kaisa a unique place to build a career? Our values aren't just posters on the wall; they guide our daily decisions:

• Innovate with Agility - We move fast, think creatively, and adapt seamlessly.

• Win Together - Success is a team effort, and we celebrate it as one.

• Own It - Accountability drives progress, and we take pride in our work.

• Champion Sustainability and Diversity - We foster inclusivity and make responsible choices.

• Spread the Vibe - A positive atmosphere fuels great ideas and connections.

We know that some people may hesitate to send their application if they feel they don't correspond to all the points of the job description. But if you feel that Kaisa and our diversity are made for you, please send us your CV!
