Role description

About commercetools
Real innovation starts with a strong foundation, and at commercetools, that comes from the perfect balance of our product and our people.

Behind every leap forward is a collective of builders, explorers, doers, makers, and problem-solvers.The kind of people who not only pioneered a more flexible approach to commerce architecture but also shaped the culture of experimentation that approach unlocked. Together, they are the engine of commerce innovation today.

At commercetools, we power the next era of commerce for our customers. Whether it's AI-driven solutions that help enterprises make smarter business decisions, bridging digital and physical shopping experiences, or enabling entirely new ways for industries to connect with their customers, we help the world's most ambitious companies experiment, scale, and grow without limits.

Here, the best idea wins, not the loudest voice. You will have the tools, trust, and space to not only build the future of commerce but to build your own.

Your Impact
As a
Senior Search Engineer
on our
Discovery Team
, you will build the retrieval layer behind product discovery for some of the world's most demanding commerce brands.

Search is changing shape. Shoppers type full sentences instead of keywords, and increasingly the client calling our API is an AI agent rather than a person. We are on the path to take our semantic and hybrid retrieval to general availability, and tackling the hard problems: making it fast, affordable, measurably better across enterprise catalogs, and working out what comes after it. You would join that work at every layer, from query understanding down to the vector index and the cost of a single query.

You will:

  • Design and implement search functionalities in a PaaS ecommerce Scala backend
  • Develop search capabilities that combine lexical, semantic, and hybrid retrieval
  • Develop search-related libraries based on ElasticSearch and MongoDB
  • Contribute to search relevance and quality, and to how we measure it
  • Run and maintain a scalable search "infrastructure as code" on top of Kubernetes using terraform and multi-tenant architecture
  • Test software components regarding usability, functionality, and performance, and work closely with Product Management and DevOps
  • Learn Scala and functional programming as your new main development tools
  • Take part in on-call rotation with a worldwide distributed team for production systems

This role is hybrid, with three days a week spent in our
Munich, Berlin, London or Valencia
office.
What Sets You Apart
You're a creative problem-solver who is wired to find solutions. You confidently dive into complex challenges and have a talent for making them simple for others. Your curiosity drives you to constantly grow and contribute to an environment of trust and teamwork.

Great ideas come from many paths, and your unique perspective matters more than checking every box. What matters most is the mindset you bring to the work. You do not need to be an ML researcher for this role. You need to be a strong backend engineer who is genuinely interested in retrieval quality.

You bring:

  • At least 5 years of experience as a Software Engineer, with production experience on the JVM
  • Solid understanding of parallel and asynchronous programming, as well as non-blocking I/O
  • Experience developing REST APIs and knowledge of scalable architectures, including sharding, replication, load balancing, and failover
  • Interest in working with Scala using pragmatic functional programming patterns. If you come from another JVM language, we will support you in picking it up.
  • Fluent English for work in international teams
  • Experience operating multi-tenant SaaS where one tenant's load must never affect another's
  • Knowledge of scalable event-driven architectures, including queues and notification topics
  • A genuine curiosity for using AI tools to work smarter and more effectively, paired with a drive to learn and put them into practice in your role.

Nice to Have:

  • Hands-on search experience, preferably ElasticSearch or OpenSearch, including a working understanding of how an inverted index scores and ranks documents
  • Practical exposure to vector retrieval, such as embeddings, approximate nearest neighbor indexes, and hybrid ranking, and a sense of where each approach breaks down. A deep lexical search background plus a clear appetite to go into this territory also works.
  • Comfort reasoning about relevance with data, including precision and recall tradeoffs, ranking metrics, and behavioral signals
  • Experience with infrastructure work and other technologies like Helm, Kubernetes, and Rust

Establish evaluation frameworks for predictive models (standard ML metrics, backtesting) and agentic systems (task completion, hallucination detection, tool-use accuracy, latency budgets).
  • Technical Leadership & Collaboration:
    Drive build-vs-buy and framework selection decisions backed by prototypes and benchmarks. Mentor ML engineers through technical design reviews, code reviews, and architectural guidance.

Required Experience

  • Core Background:
    6+ years in machine learning engineering, applied ML, or closely related software engineering roles with recent, demonstrated production delivery.
  • Production ML at Scale:
    2+ years building and operating production ML systems handling real traffic and business-critical decisions (not just notebooks or proof-of-concepts).
  • Databricks ML & AWS Ecosystem:
    Production experience with Databricks ML ecosystem (MLflow, Model Serving, Feature Store, Unity Catalog) and supporting AWS services (SageMaker, Bedrock, S3, Lambda, Step Functions, ECS/EKS).
  • Agentic AI Production Systems:
    Hands-on experience building agentic AI systems (multi-step orchestration, tool use, planning loops, memory management, human-in-the-loop patterns).
  • Core Tech Stack & Software Engineering:
    Deep proficiency in Python and ML frameworks (PyTorch, TensorFlow, scikit-learn, XGBoost) with strong software engineering fundamentals (testing, version control, code review, CI/CD).
  • LLM & Inference Experience:
    Production experience with LLM applications (RAG pipelines, vector databases like Pinecone/Weaviate/Chroma/pgvector, embeddings, prompt engineering, fine-tuning) and real-time/batch inference optimization (quantization, distillation, caching).

Preferred Qualifications

  • Experience with multi-agent system architectures (specialization, inter-agent communication, shared state management, failure recovery).
  • Production experience with model fine-tuning and RLHF/DPO alignment techniques.
  • Hands-on GPU infrastructure management, distributed training, and compute optimization on AWS (EC2 GPU, SageMaker training jobs, Bedrock custom models).
  • Familiarity with streaming ML (online learning, real-time feature computation, event-driven inference) and AI guardrail/safety systems (content filtering, output validation, cost controls).
  • Contributions to open-source ML tooling or published applied ML work.
  • MS or PhD in Computer Science, Machine Learning, or a quantitative field (practical production experience weighted equally).

Benefits

  • High Technical Impact:
    A unique professional challenge to shape production predictive AI models and agentic orchestration workflows for a stable, market-leading global enterprise.
  • Competitive Compensation:
    Senior level base salary and annual target bonus.
  • Benefits Package:
    Cafeteria allowance and private health insurance package.
  • Flexibility:
    Hybrid working model requiring 3 days of office presence (Budapest) and offering 2 days of Home Office per week.
