About the Role

Andercore utilizes AI agents for global trade operations, including sourcing, pricing, sales, logistics, and financing. This role involves owning business problems end-to-end, from data models and services to AI agents and user interfaces, ensuring reliability and quality in a dynamic environment.

Responsibilities

  • Own a business problem from first conversation to production and beyond, for example making supplier pricing reliable from ingestion all the way to the quote a salesperson sends.
  • Build backend services for pricing, inventory, orders and the integrations that connect suppliers, customers and logistics partners.
  • Build our AI agents and the tools and APIs they use, and make their actions safe through idempotency, validation, audit trails and human review where it matters.
  • Design and build the interfaces where our commercial teams work with agents: reviewing proposals, correcting mistakes and approving decisions quickly.
  • Turn messy external data such as supplier price lists, datasheets and stock feeds into trustworthy data the rest of the business relies on.
  • Measure whether what you shipped works, including evaluating and monitoring LLM-driven workflows in production.
  • Lead technical decisions, write down the trade-offs, and mentor other engineers through code review, pairing and direct feedback.
  • Help us hire by running interviews and defining what good engineering looks like at Andercore.

Requirements

  • At least 5 years of experience building and running software in production, with real users and real consequences when it fails.
  • Strong backend skills at production scale in Java or a comparable language such as Kotlin, C# or Go, and willingness to work in Java and Spring Boot.
  • Experience designing distributed, event-driven systems, with a focus on data correctness and failure modes.
  • Solid command of PostgreSQL and hands-on experience with AWS.
  • Full-stack delivery is expected: you build frontends in TypeScript and React. You don't need to be a frontend specialist, but you can ship a good interface for the problem you own.
  • Product sense: you ask why before how, you talk to users, and you can turn a vague problem into a clear plan.
  • Experience in a fast-growing company, where priorities shift and you keep shipping while the business changes around you.
  • A track record of solving business problems, not only technical ones.
  • Curiosity and good engineering judgment about LLMs and agent frameworks is a must.
  • You raise the level of the people around you, and you push back when something doesn't make sense.

  • For the customer, it feels like buying from their preferred local supplier; for our partners, it is the most convenient and safe way to do business across borders.

  • Strong triple-digit-million euro turnover
  • Seven European markets live
  • 80+ people across Berlin (HQ), offices in London, Mumbai, and Shanghai
  • $40M Series B just closed, $75M raised to date from Atomico, Project A, and Inven Capital, institutional financing from international banks.
  • We are building the world's first and last industrial-grade AI operating system for materials, redefining how global trade works in one of the largest and most essential industries on earth.

Equal Opportunity
