About Qdrant
Qdrant is a fully remote, cutting-edge technology company building the next generation of AI-native search infrastructure through our open-source vector database and managed Cloud offering. Our platform powers real-time search, recommendation systems, and AI workloads across major cloud providers worldwide.
As we scale, we are strengthening core domains across our Cloud platform — including billing, identity, provisioning, admin workflows, integrations, and usage metering — and we are looking for a Staff-level engineer who can take technical leadership across multiple areas , not just one single domain.
Tasks
Role Overview
We are hiring a Staff Backend Engineer with Technical Lead responsibilities who will take ownership of complex backend domains and drive architectural clarity, execution quality, and cross-functional alignment across the Cloud organization.
Your initial focus will likely involve a high-priority domain such as Billing, Payments, or Usage Metering , but this is not a billing-only role. Because Qdrant operates in a fast-paced, evolving environment, this person must be comfortable—and motivated—to take ownership of other business-critical domains as priorities shift.
This is a senior individual contributor role with broad architectural influence, strong cross-functional leadership expectations, and a direct impact on the direction of our Cloud platform.
We prefer candidates based in EMEA for optimal collaboration.
Requirements
What You’ll Do
Technical Leadership & Architecture
Own the architecture and technical strategy of one or more high-impact backend domains.
Drive system design, establish service boundaries, and shape long-term platform evolution.
Modernise legacy systems and lead migrations toward clean, scalable, maintainable architectures.
Define engineering standards, architectural guardrails, and review best practices.
Ensure correctness, reliability, observability, and maintainability across the systems you own.
Technical Lead Responsibilities
Provide technical direction for your domain and act as the main engineering point of contact.
Collaborate with Product, Finance, Growth, Support, and Platform teams to translate requirements into robust engineering solutions.
Execution & Delivery
Ensure technical execution is predictable, aligned, and sustainable.
Remove blockers that hinder delivery or compromise system stability.
Champion observability, operational excellence, and data correctness.
Guide teams through ambiguity and evolving priorities.
Adaptability in a Fast-Paced Environment
Bring relevant experience in a critical domain (billing/payments/usage metering strongly preferred), but be ready and motivated to take ownership of other business areas as the company evolves.
Adapt quickly to new problem spaces, shifting priorities, and emerging business demands.
Help create technical clarity in domains that may still be undefined or require rapid iteration.
Domain Expertise (Billing as a Strong Plus)
While the role is intentionally multi-domain, experience in one or several of the following is highly valuable:
Billing, Payments, Pricing Models
Usage Metering, Event Pipelines
IAM / Identity & Access
Provisioning, Orchestration, Infrastructure SaaS workflows
Backoffice/Admin systems
Financial correctness, reconciliation, auditability
What We’re Looking For
Required Technical Expertise
Strong proficiency in Python and Go (both required).
Deep experience designing and evolving distributed systems.
Excellent understanding of relational databases (PostgreSQL preferred).
Familiarity with Kubernetes, Docker, and major cloud providers.
Track record of building or significantly improving complex backend systems.
Required Leadership Capabilities
Strong experience leading technical direction as a Senior or Staff IC.
Ability to act as a Technical Lead across one or more domains.
Excellent communication skills, including the ability to explain complex engineering concepts to non-engineers.
Ability to mentor engineers and raise the technical bar across teams.
Comfortable influencing roadmap decisions and representing your domain in leadership discussions.
Nice to Have
Experience with billing, pricing, usage metering, payments, or reconciliation workflows.
Experience with event-driven architectures, ledgers, data pipelines, or event sourcing.
Experience with gRPC, GraphQL, or API-first design.
Familiarity with observability tools like Prometheus, Grafana, OpenTelemetry.
Background in SaaS, fintech, or marketplace payment systems.
