Senior Software Engineer II

Role description

Role Overview

Senior engineers are area owners who lead designs, raise engineering standards, and deliver measurable improvements to latency, throughput, and reliability across multiple services. You'll partner with product, orchestration, and hardware teams to evolve our Kubernetes-native inference platform and meet strict P99 SLAs at scale.

What You Will Do

Lead design reviews and drive architecture within the team; decompose multi-service work into clear milestones. Define and own SLIs/SLOs; ensure post-incident actions land and reliability improves release-over-release. Implement advanced optimizations and quantify impact. Strengthen incident posture: capacity planning, autoscaling policy, graceful degradation, rollback/traffic-shift strategies.

Why It Might Be a Fit

We support and encourage an entrepreneurial outlook and independent thinking. We foster an environment that encourages collaboration and enables the development of innovative solutions to complex problems.
