About Upsun

Upsun is the software factory for human-AI workflows. We give teams one unified platform to create, review, deploy, and run software, with AI agents and humans working in sync. Developers, DevOps engineers, and platform teams use Upsun to build and ship with confidence, without wrestling with infrastructure.

Upsun brings this together through two products: one that shapes the work, and one that runs it.

Upsun Dispatch™: the AI-first product accelerator. Dispatch governs and simplifies collaboration between AI agents and cross-functional human teams, so work gets shaped, reviewed, and moved to production faster. Ship better code, not just more code.
Upsun Cloud: the Cloud Application Platform for AI acceleration. Cloud is where that software runs. It helps organizations launch agentic software into production confidently and reliably, with:
Predictable performance, even at scale
Secure, compliant environments by default
Real-time observability and profiling built in
Cloning, configuration, and provisioning in seconds
Sandbox environments where AI agents can build and test safely

The name says it all. "Up" means uptime, reliability, and acceleration. "Sun" reflects our follow-the-sun-support, a 24x7, globally distributed support team keeping the lights on while you rest. Our core belief is that software should power brighter solutions and greater innovation.

What's our commonality, our cultural fabric? A curious spirit and a thirst for knowledge; an eagerness for innovative ideas and cultures. We believe we can build anything together in an environment that frees you to do your best work.

Our values:

🌿 We make a positive impact.

✨ We aim for the stars.

💚 We care for each other.

Impact of a Senior Site Reliability Engineer

As a Senior Site Reliability Engineer at Upsun, you will lead the evolution of our cloud application platform from traditional cloud operations into a proactive, automation-driven SRE model. You will own critical engineering workstreams that enhance system reliability, scalability, and operational efficiency across multi-cloud environments. Partnering closely with engineering, product, and platform teams, you will embed reliability and performance into every stage of the software delivery lifecycle. In this role, you will anticipate architectural bottlenecks, drive infrastructure-as-code practices, and establish robust observability standards that ensure long-term system stability and uptime for our global users.

What to expect

Drive reliability & observability strategy: Architect and elevate system monitoring, alerting, and logging using Prometheus, Grafana, and ELK Stack, establishing actionable SLIs/SLOs aligned with core business metrics.

Automate infrastructure & workflows: Eliminate operational toil by designing and implementing resilient, automated solutions using IaC tools like Terraform and Ansible across AWS, GCP, and Azure.

Scale CI/CD & delivery pipelines: Optimize pipeline architectures for fast, secure, and zero-downtime releases, ensuring infrastructure resilience during high-volume deployment cycles.

Lead incident response & post-mortems: Guide high-priority incident triage, drive blameless post-mortem analysis, and implement preventative measures to continuously improve system resiliency.

Cross-functional leadership: Partner with product and software engineering teams to incorporate SRE best practices into product roadmaps.

Champion technical innovation: Proactively identify performance bottlenecks and evaluate emerging technologies (e.g., eBPF, container orchestration) to optimize platform stability and performance.

Time distribution: Follow a 4-week rotation balancing engineering and operations to focus on reliability, automation, and scalability through hands-on troubleshooting and engineering innovation.

What you bring

Senior SRE & Cloud Expertise: 5+ years of experience in Site Reliability Engineering, Cloud Operations, or DevOps, with proven experience owning reliability for production platforms at scale.
