Cologne, Germany Remote (Global)

Sastrify is hiring a Tech Lead (M/F/D) - Remote (EMEA, GMT+/-2)

About the Role

Lead technical execution while staying deeply involved in the code. As Tech Lead, you'll be the engineering counterpart to the Head of Product & Engineering, reporting directly to the CTO. This is a technical leadership role without managerial overhead—your focus will be on building, designing, and elevating the platform through hands-on development.

What You’ll Do

  • Write clean, scalable code across the full stack using TypeScript, React, and Node.js, with a strong emphasis on maintainability and performance
  • Design and implement AI-powered features—like agent systems, automation workflows, and LLM pipelines—that are core to the product
  • Integrate AI tools into daily development to improve planning, architecture, and code quality—not just for autocompletion
  • Make thoughtful decisions about when to use prompt engineering versus model fine-tuning, and ensure reliable output from AI components
  • Collaborate closely with product leadership to define technical roadmaps and translate business goals into feasible, well-architected solutions
  • Own the evolution of the system architecture, making pragmatic choices about tools, services, and infrastructure
  • Champion best practices in testing, documentation, and deployment, ensuring fast and stable release cycles
  • Lead by example through code reviews, pair programming, and knowledge sharing

What We’re Looking For

  • At least 7 years of professional software development experience, with time spent in senior, staff, or founding engineer roles
  • Deep expertise in the TypeScript/Node.js/React ecosystem and full-stack development
  • Proven experience with cloud platforms—AWS preferred, though GCP or Azure backgrounds are welcome if you’re ready to adapt
  • Familiarity with infrastructure as code (Terraform or similar) and event-driven systems
  • Active use of AI development tools such as Cursor, Copilot, or Claude Code in real-world workflows
  • Hands-on experience building production-grade AI features—not just API wrappers—including RAG systems, agent logic, or automated reasoning pipelines
  • Strong opinions on software design, balanced with pragmatism and delivery focus

Environment & Expectations

You’ll work in a builder-first culture that values speed, clarity, and technical integrity. The team ships to production daily, powered by fully automated CI/CD. You’ll help maintain that pace while raising the bar for quality and innovation. This is a remote role open to candidates in EMEA within the GMT±2 timezone.

While this is not a formal management role today, there’s a clear path to lead a growing team of engineers as the organization scales.
