About the Job

As a key growth accelerator, A11 partners with Europe’s most ambitious startups and scaleups, corporates and SMBs to connect them with top-tier talent ready to make an impact.

We’re looking for an experienced Backend Engineer (m/f/d) to help shape the systems that make operations predictable and scalable for our client's customers.

Join the A11 Ecosystem – A next-generation supply chain platform, the company is redefining how one of the world’s largest industries sources, distributes, and finances materials. Engineered to unlock the full potential of global trade, it harnesses agentic AI and workflow automation to provide seamless, high-efficiency access to premium materials at scale. Since its commercial rollout, the platform has fueled exponential growth, optimizing procurement for thousands of businesses while setting new benchmarks for speed, transparency, and efficiency. Its competitive edge lies in full digitization and AI-driven supply chain management automation, eliminating inefficiencies and creating a direct, intelligent bridge between suppliers and buyers. With a team of 80+ FTEs across Europe (Berlin HQ), China, and India, the company is rapidly scaling toward profitability, driving triple-digit million GMV, and setting new industry standards in autonomous, AI-powered supply chain orchestration.

In this role, you’ll:

Design and build backend services that power supply chain workflows — from order management to LSP integrations and real-time tracking
Develop event-driven pipelines that process high-throughput logistics data reliably and at scale
Build and maintain integrations with third-party logistics providers, ERPs, and warehouse management systems
Own and evolve the data models that represent complex supply chain entities: shipments, inventory positions, fulfillment nodes
Identify performance bottlenecks and lead the engineering effort to resolve them in production systems
Work with LLM APIs (OpenAI, Anthropic, Gemini) to build intelligent workflows and automation
Collaborate closely with Product and domain experts to translate operational complexity into clean technical solutions
Contribute to architecture decisions and raise the engineering bar through rigorous code reviews and documentation

Tech Stack: Java 21 (Spring Boot 3), Python, PostgreSQL, Kinesis, AWS, Terraform, GitHub Actions, Node.js, TypeScript

Your Profile:

5-7+ years of experience in backend engineering, ideally within logistics, supply chain, or operations-intensive domains
Strong command of Java (Spring Boot) or equivalent JVM-based frameworks; Python a strong plus
Experience designing systems that handle real-time data ingestion and processing (Kafka, Kinesis, or similar)
Comfortable with relational databases (PostgreSQL) and modeling complex, interrelated business domains
Pragmatic approach to distributed systems — you understand trade-offs around consistency, availability, and latency
Exposure to third-party API integrations and the messiness that comes with legacy and external systems
Intellectually curious, detail-oriented, and motivated by shipping things that work reliably in the real world.

Please note that this position is based onsite in Berlin.

Benefits and Perks:

Real ownership from day one – shape operational processes in a fast-scaling, AI-first company
Learn from the best – work directly with senior operators
Competitive compensation – attractive base salary and performance-based bonus program
Personal growth & visibility – rapid learning opportunities, cross-functional exposure, and early leadership potential in a growing global team
Vibrant company culture – modern Berlin office, monthly All-Hands, team events, and regular offsites

If you’re eager to join the A11 Ecosystem and shape what’s next, we want to hear from you!
