About The Role

ABOUT THE ROLE

This is a high-ownership engineering role at a Y Combinator–backed AI startup automating inside sales workflows for distributors and manufacturers. You'll be the technical bridge between product and customer — taking deals from sales handoff all the way to live deployment, and feeding real-world signal back into the core product.

WHAT YOU'LL DO

Own the full technical implementation lifecycle from sales handoff through go-live.
Configure and fine-tune AI models for customer-specific use cases, including prompt engineering and model behavior adjustments.
Structure customer data and build system integrations with ERP platforms (e.g. SAP) and various REST/GraphQL APIs.
Develop prototypes to demonstrate new features or solve emerging customer problems, then evolve them into scalable solutions.
Engage daily with technical teams and senior business stakeholders to translate real pain points into engineering decisions.
Act as the voice of the customer internally, surfacing product gaps and patterns to the core engineering team.

WHAT WE'RE LOOKING FOR

Native fluency in German (required).
Strong full-stack engineering skills across Python, React, TypeScript, SQL, and API development — comfortable spanning frontend, backend, and data pipelines.
Experience with enterprise system integrations, including ERP systems and REST/GraphQL APIs, webhooks, or B2B SaaS implementations.
Practical experience with LLMs, agents, and prompt engineering, with the ability to adapt model behavior to specific domains.
Proven ability to work with messy, inconsistent real-world data and establish reliable structures quickly.
Customer-obsessed approach — thrives at the intersection of engineering, product, and live customer environments.
High agency: proactively identifies problems and drives solutions with minimal direction.
Strong communication skills, able to explain complex technical concepts to both technical and non-technical audiences.
Comfortable with ambiguity, legacy systems, and a scrappy, problem-solving mindset.
