Senior Search Backend Engineer (m/f/x)

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
