at Semios

🏢 About Semios

Semios is at the forefront of sustainable agriculture, using IoT and data analytics to reduce pesticide use and crop losses. Their mission-driven approach combines cutting-edge technology with environmental impact, offering a unique opportunity to work on infrastructure that directly supports global food security.

About This Role

As a Senior Site Reliability Engineer, you'll lead critical infrastructure projects ensuring the scalability and reliability of Semios's data-driven pest management platform. Your work directly impacts farmers' ability to reduce chemical inputs while maintaining crop health, making this role both technically challenging and socially meaningful.

💡 A Day in the Life

Start the day reviewing dashboards and alerts from Datadog, then join a standup to discuss ongoing infrastructure projects. Spend the morning coding a Terraform module for auto-scaling, followed by a mentoring session with a junior engineer on Kubernetes best practices. After lunch, respond to a minor incident by coordinating with the team, then update runbooks and review pull requests before the end of the day.

3

Showcase your mentoring approach: provide examples of how you've upskilled team members or implemented SRE best practices.

4

Tailor your resume to emphasize cloud cost optimization and scalability, as Semios likely handles large datasets from numerous sensors.

5

Include a link to your GitHub or a portfolio demonstrating infrastructure-as-code and automation skills, especially with Terraform and Kubernetes.

✉️ What to Emphasize in Your Cover Letter

To stand out, make sure you've researched:

  • → Read about Semios's core product: how their sensors and data analytics reduce pesticide use. Understand their data pipeline from field to cloud.
  • → Look into their blog or press releases for recent infrastructure challenges or scale achievements (e.g., number of acres monitored).
  • → Research their technology stack: they use AWS, so familiarize yourself with their specific services (IoT Core, Lambda, etc.).
  • → Check their engineering culture on Glassdoor or LinkedIn for mentions of on-call practices and team structure.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 How would you design a scalable infrastructure for thousands of IoT devices sending real-time data?
2 Describe a time you automated a manual process to improve reliability. What was the impact?
3 How do you approach incident post-mortems? Give an example of a systemic change you implemented.
4 Explain your experience with Kubernetes in production. How do you handle cluster upgrades and resource optimization?
5 How would you mentor a junior engineer on SRE principles while maintaining on-call responsibilities?

⚠️ Common Mistakes to Avoid

  • Downplaying the importance of on-call: be upfront about your experience and willingness to participate in a rotation.
  • Focusing only on tools without connecting to business impact: always tie your technical achievements to reliability or cost savings.
  • Ignoring the agricultural context: failing to show interest in sustainability or IoT can signal a lack of cultural fit.
