Brellium Senior Backend / Infrastructure Engineer at Brellium designing backend systems to scale session volume 10x. Architect and build distributed systems ensuring reliability, observability, and performance under high load.
Responsibilities
We're hiring a Senior Backend / Infrastructure Engineer to design the systems that let Brellium scale 10x. We currently process ~100k sessions per day – and we're building toward 1 million+. That requires robust distributed systems, resilient pipelines, and infrastructure that doesn't break under load. You'll architect and build the backend systems that ensure reliability, observability, and performance as volume increases by an order of magnitude.
Design and evolve distributed systems to support 10x growth in session volume
Improve throughput, fault tolerance, and system resilience across the core pipeline
Build scalable data pipelines and processing infrastructure
Strengthen observability, monitoring, and incident response
Reduce operational bottlenecks and technical debt
Collaborate with AI and product teams to ensure the underlying systems can support new capabilities at scale
YOU MIGHT BE A FIT IF YOU
Have scaled systems handling high throughput or real-time processing
Are comfortable with distributed architectures and failure modes
Think in terms of system design, not just features
Have strong backend fundamentals: databases, queues, concurrency, APIs
Qualification
Required
5+ years of professional software engineering experience with a backend/infrastructure focus
Expertise in Python and AWS infrastructure.
Experience building and scaling data-intensive applications and pipelines
Strong understanding of distributed systems, concurrency, and database internals
Proven track record of improving system reliability and performance in production
