About UsDo you want to take ownership from day one and actively shape the future in a growing company? VoiceLine is a fast-growing, VC-backed startup based in Munich. We build an AI-powered solution that not only helps field sales and service teams turn conversations into structured data efficiently, but also helps them be smarter on the road. This enables customer information to be documented, analyzed, and seamlessly integrated into existing systems. Together with leading enterprise customers, we are working to make field sales future ready.
The RoleYou'll lead VoiceLine's Full Stack team, the engineers who build the product our customers' field reps use every day, across the web app, the backend and the AI features in between. You set the technical bar, grow the team, and make sure what we commit to is what we ship.
Your MissionAs Full Stack Lead, you own both the people and the product surface of your team. This is a player-coach role. You spend real time in the code, with coding agents as a normal part of how you and your team work, while you build a team that ships predictably and keeps getting better.
Responsibilities
- Lead, coach and grow the Full Stack team through 1:1s, feedback and career development, and hire alongside the CTO
- Stay hands-on: design and build features across backend and frontend, and review the work that matters most
- Own the technical direction of your team's domain, including architecture, code quality, testing, and the trade-off between speed and long-term health. That includes deciding what to delete.
- Turn roadmap commitments into realistic plans, track them honestly, and re-forecast early when something slips
- Take AI-powered features from prototype to production, and make sure their output is verifiable and measurable
- Shape how your team works with coding agents: shared context, conventions, and documentation treated as a contract
- Make onboarding fast, so new engineers ship real work within their first weeks
- Be the bridge to Product, Design, AI, Data and Customer Delivery, and spend time in the field with customers so the team builds from first-hand experience
