Empower businesses to succeed! Sastrify safeguards your digital supply chain with state of the art software management. Our AI-powered platform eliminates Shadow IT, automatically assesses vendor risk, and provides required documentation and monitoring along compliance frameworks like NIS2, ISO and DORA. We support IT leaders in measuring and managing secure AI adoption within their organizations.

Launched in 2020 and backed by leading venture capital investors like FirstMark (also supported Airbnb, Shopify, and Pinterest), we already serve hundreds of clients globally (such as TeamViewer, sennder or On).

Joining Sastrify means being part of a fast-paced, forward-thinking team where your work will make a real difference.

We're looking for a Tech Lead who acts as the primary technical counterpart to our Head of Product. This is a high-impact, hands-on role (70%+ coding) designed for a seasoned engineer who loves the craft of building software as much as the "why" behind product decisions. You will bridge the gap between product discovery and technical execution, ensuring our roadmap is ambitious yet technically sound.

You'll report directly to our CTO and work as the voice of engineering in product discussions. 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)

• Product Partnership: Collaborate daily with the Head of Product to translate vision into a robust technical roadmap. You'll be engineering's voice in product discovery.

• AI-Native Development: Pioneer AI-native workflows, leveraging AI tools to accelerate team velocity. Lead the charge in integrating LLMs, agents, and automation into the Sastrify platform.

• Hands-On Execution: Lead by example. Write high-quality, production-ready code across the full stack (React/Node.js). Tackle the most complex technical challenges yourself.

• Technical Evolution: Evolve our full-stack architecture pragmatically, ensuring our environment remains performant and cost-effective as we scale.

• Technical Feasibility: Evaluate new feature requests for technical risk and effort. Provide high-level estimates and alternative paths to achieve business goals.

• Data & Integration Strategy: Drive the technical strategy for integrating with diverse, high-volume customer data sources, ensuring robust data ingestion, reliability, and architectural transparency to deliver maximum user value.

• DevOps Excellence: Advocate for and implement best practices in IaC (Terraform) and CI/CD. Keep deployment cycles fast and reliable.

• Mentorship & Quality: Drive technical excellence through deep code reviews, pair programming, and setting standards for documentation and testing.
