How to Apply for Senior Site Reliability Engineer
at Semios
🏢 About Semios
Semios combines cutting-edge data analytics with agriculture to create a more sustainable food system, reducing pesticide use by up to 95%. Their mission-driven approach appeals to engineers who want to apply their skills to environmental impact.
About This Role
As a Senior SRE, you'll architect and maintain the cloud infrastructure that powers real-time pest and disease monitoring for thousands of farms. Your work directly enables farmers to reduce chemical inputs, making a tangible impact on global sustainability.
💡 A Day in the Life
Your morning might start with reviewing dashboards for any overnight alerts, then pairing with a junior engineer on a Terraform module. After a standup, you'll lead a postmortem for a recent incident, followed by coding an automation to reduce deployment toil. Afternoons often involve design discussions for scaling the IoT pipeline to handle next season's data volume.
🚀 Application Tools
🎯 Who Semios Is Looking For
- Has 8+ years in DevOps/SRE with deep AWS, Terraform, and Kubernetes expertise, plus strong programming in Python or Go.
- Thrives on data-driven reliability improvements using tools like Datadog or New Relic to proactively prevent incidents.
- Loves mentoring and leading by example—you'll shape SRE culture and practices across the engineering team.
- Is comfortable with on-call rotation and views it as a chance to build better systems, not just a burden.
