Senior Full-Stack Engineer

About the Role

We're a fast-growing, Munich-based AI-powered B2B SaaS company (founded 2022, ~25 people) building privacy-first productivity tools for sales teams. Our product spans a web app, desktop client, iOS app, and backend services — all centered around real-time, low-latency data processing and seamless CRM integrations.

As a Senior Full-Stack Engineer, you'll take technical ownership of a major platform surface, work directly with the CTO and founding engineers to shape product and infrastructure strategy, and help define how we build and ship software at scale. This is a high-impact, high-autonomy role at the heart of our engineering team. The role is hybrid and based in Munich, Germany. Visa sponsorship is not available.

What You'll Do

• Own a platform — web, desktop, iOS, or backend — and deliver real-time, low-latency features end-to-end.

• Architect scalable services and define cross-stack best practices that balance performance, reliability, and product velocity.

• Collaborate closely with the CTO and founding engineers to shape product direction and infrastructure strategy.

• Mentor junior engineers, lead code reviews, and foster a high-performing, learning-oriented engineering culture.

• Build and maintain a robust delivery pipeline, including CI/CD, test automation, and deployment strategies.

• Document architectural decisions and communicate clearly across engineering, product, and infrastructure teams.

What We're Looking For

Required:

• Expertise in TypeScript, React, and Node.js with a strong modern full-stack development background.

• Familiarity with Swift or C++ (at least one is required).

Strongly valued:

• Experience building and operating real-time, low-latency features and performance optimizations.

• Exposure to audio, voice, or AI technologies.

• Experience with privacy-focused architectures or real-time data pipelines.

• Strong track record with CI/CD pipelines, test automation, and delivery infrastructure.

• Experience designing and operating scalable distributed systems / microservices across web, desktop, and mobile.

• Familiarity with cross-platform development (web, iOS, desktop).

• Proven ability to lead technical decisions, perform code reviews, and shape architectural direction.

• Previous experience as a technical lead or CTO at a startup.

• Mentoring and coaching junior engineers with a track record of building high-performing teams.

• Contributions to open-source projects or personal side projects you're proud of.

• University degree in Computer Science, Mathematics, or an adjacent technical field.

• Strong CS fundamentals.

Location & Work Arrangement

• Hybrid role based in Munich, Germany.

• Visa sponsorship is not available — candidates must have the right to work in Germany.

Compensation & Benefits

Compensation is competitive and commensurate with experience. Specific details will be discussed during the interview process. You'll be joining a small, high-calibre team at an early stage with meaningful equity participation and direct influence over technical direction.
