We are looking for an experienced Senior Backend Engineer to join a team responsible for building and scaling a high-throughput, event-driven platform operating at massive scale.

Your primary focus will be the event processing backbone — designing, developing, and optimizing services that handle large volumes of messages reliably and efficiently. You will work closely with architects and other senior engineers to implement APIs that expose data and support advanced triage and processing workflows.

This role is ideal for someone who enjoys solving hard scalability problems, working with distributed systems, and building resilient backend services that operate under real-world load.

Responsibilities

Design and build backend services responsible for large-scale event processing
Optimize and scale message-based systems to handle high throughput and reliability requirements
Implement APIs defined by system architects to expose data and collect processing results
Collaborate with cross-functional teams to improve platform performance and resilience
Contribute to architectural decisions around scalability, fault tolerance, and observability

Core Skills

Strong experience with Python as a primary backend language
Deep expertise in scaling message queue systems (e.g. Azure Service Bus, Storage Queues, Event Hubs or similar)
Solid understanding of microservices architecture and distributed systems
Proven experience building high-throughput, resilient backend services
Strong problem-solving skills and ability to work with complex systems

Highly Desirable

Experience with event-driven or event sourcing architectures
Background in data processing frameworks or streaming systems
Experience building platforms related to observability, monitoring, or large-scale event management
Familiarity with designing systems for fault tolerance and graceful degradation

What we offer

Work on technically challenging systems operating at very large scale
High level of autonomy and real influence on system architecture
Collaboration with experienced engineers in a mature engineering environment
Competitive compensation and flexible working model
Project with strong technical ownership
