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.
