ABOUT THE ROLE Join a small, fast-moving team at a Y Combinator–backed conversational AI SaaS startup building an AI voice platform that automates customer call operations at scale for B2C companies. You'll work on a product that handles thousands of AI-powered phone calls every day — spanning sales, support, and operations — and you'll do it in person alongside a sharp, low-ego team in Berlin. This is a high-ownership, end-to-end engineering role. You'll shape core architecture, ship features with speed, and work directly with customers to turn real problems into elegant product experiences. WHAT YOU'LL DO - Work closely with customers to understand their challenges and design product experiences that genuinely solve them. - Build scalable backend infrastructure capable of handling thousands of concurrent AI phone calls per day. - Create intuitive, AI-first user experiences on the frontend. - Own high-stakes projects end-to-end — from initial concept through production launch and post-release support. - Contribute to core architectural decisions that shape the direction of the platform. WHAT WE'RE LOOKING FOR Required - 2+ years of professional software engineering experience. - Proficiency with TypeScript, React, Node.js, and Python. - Strong PostgreSQL experience. - Proven ability to design scalable backend architectures and make meaningful product/architectural decisions. - Experience taking a product from 0 to 1 — you've built something from the ground up. - Ability to own projects end-to-end: concept → production → post-release support. - Strong collaboration skills — you're comfortable working directly with customers and cross-functional teammates to translate problems into solutions. Nice to Have - Familiarity with Temporal.io, Twilio, or Modal. - Experience with scalable async or real-time processing systems. - Background building products for AI-first or communications-enabled platforms (e.g. voice, telephony, conversational AI). COMPENSATION & BENEFITS - Salary: $75,000 – $160,000 USD annually (depending on experience) - Visa sponsorship available - Early-stage equity opportunity - Work at a well-funded, high-growth startup backed by top-tier investors LOCATION This role is on-site in Berlin, Germany. We're looking for people who are genuinely excited to work in person with the team — not a remote-first environment.
