Who We Are

DAITA is a German AI start-up. We’re transforming the fashion supply chain with AI-powered agents that automate the mundane, freeing teams to focus on creativity, strategy, and growth.

After a successful research phase spanning 8 countries across 3 continents—gathering insights from Indian cotton fields to German retailers—we’ve secured pre-seed funding and key industry partnerships.

Now, we’re building our MVP to deliver speed, precision, and ease to one of the world’s biggest industries.

We’re set on hypergrowth, aiming to redefine textiles with intelligent, scalable tech—and this is your chance to join the ground floor of something huge.

What You’ll Do

As our Chief Engineer, you’ll lead the technical charge to make our vision real, starting with our MVP in a 3–5 month sprint. You’ll:

• Design and code an AI-driven/agent system (leveraging machine learning and NLP) with integrated workflow automation to streamline and automate tasks in the textile supply chain, owning it from scratch to finish.
• Develop backend systems, utilize cutting-edge tools, critically assess manpower needs beyond yourself, oversee a small support team, and drive toward our aggressive launch timeline.
• Collaborate closely with our founders to align tech with ambitious goals and client input, ensuring automated workflows deliver speed, precision, and ease to textile industry stakeholders.
• Build an MVP that scales to millions, integrating APIs and data pipelines, using major cloud platforms (AWS, Azure, Google Cloud)—keeping us nimble now and primed for explosive growth later.

What You Bring

• 2–5 years of experience at high-growth startups or leading tech firms—where you shipped real products, solved complex problems, and moved fast.
• End-to-end ownership: You've taken tech projects from zero to one—built systems from scratch, made architecture decisions, handled messy edge cases, and delivered under pressure.
• Team Leadership: 1–3 years leading engineering teams, ideally including recruitment and delivery in India.
• Technical horsepower: AI Agent Experience, strong across full-stack or backend engineering, ML/NLP integration, cloud architecture, and API/data pipeline development. Experience with workflow automation tools and platforms (e.g., Apache Airflow, UiPath, or similar) to automate processes, ideally in supply chain or textiles. You can code an MVP solo if needed.
• Resource Clarity: Bring as much technical expertise as possible to build our MVP, and if you can’t own every piece, clearly identify the specific areas where you’ll need team members to deliver on time.
• Vision Alignment: You think like a builder, taking ownership of the product and team as if it were your own, while partnering closely with the founders to execute their vision with trust and decisiveness.
• Execution DNA: You ship fast, iterate intelligently, and know when to be scrappy vs. when to be solid.
• Problem-First Thinking: You’re obsessed with solving real user problems, understanding stakeholder needs beyond just writing beautiful code.
• High-Energy Leadership: Hands-on, humble, and always ready to jump into the trenches. You lead by doing.
• Geographical Fit: India-based, ideally with previous exposure to international teams or founders.
• Values-driven: You live our culture—live in the future, move fast, one team, and character above all.

Why Join Us?

• Be the technical linchpin of a hypergrowth startup—build the MVP that launches us into the stratosphere.
• Competitive salary and equity options to negotiate—own a piece of something massive.
• On-site in our Tiruppur (Tamil Nadu) offices for 2 months with the German founders, to sync with the founders, then remote flexibility long-term.
• A full-time role demanding full availability—put in the time needed to smash deadlines and reshape the second-biggest industry on Earth with a team that moves fast and rewards hustle.
