The role

Qdrant is an open-source vector search engine powering the next generation of AI applications, from semantic search and retrieval-augmented generation (RAG) to AI agents and real-time recommendations.

Trusted by global leaders like Canva, HubSpot, Tripadvisor, Bosch, and Deutsche Telekom, we're building the retrieval infrastructure layer for modern AI. Recently raising $50M in Series B funding, we are growing rapidly and committed to transforming how AI understands and interacts with data.

As a remote-first company, we believe diverse backgrounds, perspectives, and experiences fuel innovation. Here, you'll own meaningful work, tackle challenges, and grow alongside passionate individuals dedicated to shaping the future of AI.

What you'll do

As a Senior Software Engineer on the Platform team, you will work on the core cloud platform that enables all other engineering teams at Qdrant. You'll design and evolve shared services, control-plane components, and internal APIs that power our managed cloud offering and support enterprise-grade deployments.

This role is about building platform primitives and abstractions, not day-to-day operations. You'll focus on reducing complexity, improving developer productivity, and driving architectural evolution across the cloud platform.

Design and evolve core platform services and internal APIs consumed by multiple teams.
Drive architectural initiatives such as gRPC migration, eventing/pub-sub foundations, and platform refactors.
Own and improve control-plane and cluster-api components.
Build platform abstractions that reduce operational and cognitive load for other teams.
Write production-grade Go code for platform services and internal tooling.
Collaborate closely with Regions & Clusters, Resilience, and Features teams to enable delivery through platform primitives.
Improve platform scalability, reliability, and developer experience through thoughtful design.
Support production systems and incident response when needed, with a focus on long-term fixes.

Why join us

A remote-first, international team working on cutting-edge AI infrastructure.
A competitive salary with additional perks.
Flexible working hours and async-friendly culture.
High ownership and real impact.
Open-source, engineering-driven culture.
Choose your own laptop equipment.

Strong understanding of distributed systems and API design.

Familiarity with Kubernetes operators or cluster-level abstractions.

Contributions to open-source projects.

Pay & benefits

What you'll get

For US-based full-time employees, we also offer a comprehensive benefits package including 401k match, health, dental, and vision insurance, plus flexible PTO policy.
