• Own the content architecture • Design the full content schema in Sanity.io from the ground up — services, treatments, providers, booking flows, blog, FAQs — with clean document types, structured portable text, and a model that non-technical editors can actually use. • Build the frontend • Develop the Next.js frontend consuming Sanity’s GROQ API — with a deliberate ISR/SSR strategy, image optimization, and SEO fundamentals built in from the start, not bolted on later. • Own the deployment pipeline on Vercel — preview environments, CI checks, and rollback capability. • Build and maintain integrations • Connect the CMS to third-party booking and scheduling platforms — API-first, cleanly abstracted, and resilient to the inevitable upstream changes. • Work independently and communicate clearly • Manage your own delivery — you’ll have context, goals, and access to stakeholders, not a Jira board of pre-scoped tickets.

Empower businesses to succeed! Sastrify is building the future of software management. Our AI-powered platform helps IT, Procurement, and Finance teams discover, acquire, and optimize their software landscape. Founded in Cologne in 2020, we’ve raised €57M+ from top-tier investors (FirstMark, Endeit, HV Capital) and serve 50,000+ users. Join our team of Sastronauts! We’re looking for a Tech Lead who acts as the primary technical counterpart to our Head of Product & Engineering. This is a high-impact, non-managerial, 70%+ hands-on coding role designed for a seasoned engineer who loves the craft of building as much as the “why” of product development. You’ll report directly to the CTO and bridge the gap between product discovery and technical execution. As we scale, you’ll have the opportunity to build and lead a small team of engineers who will report to you. Ready to shape the future of SaaS management? Let’s do it together! You'll be working with Max Messing, CTO and Lars Klein, Head of Product. What you’ll do as our Tech Lead (m/f/d) - Hands-on Execution: Lead by example by writing high-quality, production-ready code across the entire stack (React/Node.js). You’ll tackle the most complex technical challenges and set the quality bar for the team. - AI-Native Development: Pioneer AI-augmented development workflows for the entire team. We don’t just want someone who “uses Copilot” — we want someone who can architect AI features (LLMs, agents, automation) into our platform AND use AI tools to fundamentally change how our team ships code. You should have opinions on when to prompt-engineer vs. fine-tune, how to evaluate LLM output quality, and how to build reliable AI pipelines in production. - Product Partnership: Collaborate daily with the Head of Product & Engineering to translate the product vision into a robust technical roadmap. You’ll be the “voice of engineering” in product discovery. - Technical Evolution: Define and evolve our full-stack architecture. We’re pragmatic about our infrastructure — the right tool for the right problem, not dogmatic about any specific cloud pattern. - Technical Feasibility: Evaluate new feature requests for technical risk and effort, providing high-level estimates and alternative technical paths to achieve business goals. - DevOps Culture: Advocate for and implement best practices in IaC and CI/CD, ensuring our deployment cycles remain fast and reliable. - Mentorship & Quality: Drive technical excellence through deep code reviews, pair programming, and setting the standard for documentation and testing. Our Tech Stack - Front-End: TypeScript, React.js, React Query, Storybook - Back-End: Node.js, TypeScript, PostgreSQL (via TypeORM) - Infrastructure: Serverless Framework, AWS Lambda, Terraform - AI/LLM: AI SDK, LangChain.js, Agents SDK for building AI-native features - Workflow: Fully automated CI/CD with daily production deployments
