Job description

Full Time CA

Salary Range: $80,000.00 To $130,000.00 Annually

Lasso Informatics is a SaaS start-up with a live research data management and analysis platform that brings together multi-modal (imaging, genetics, behavioral, and biosample) data for large-scale studies. Thousands of researchers across the globe rely on our platform today, and we are rapidly iterating and improving to push the boundaries of what is possible in research data management.

We live to innovate, and empower scientists to focus on the science, not the technology, leading to a faster time to science and cure.

Our team is incredibly diverse both by background and expertise, and that is not by accident. We believe that the most creative and powerful solutions come from different ways of thinking about the world. You will be working in an inspiring ecosystem alongside world-renowned professionals in medicine, physics, engineering, imaging, epidemiology, software development, and genetics. We thrive on empowering our colleagues to be thought leaders and innovate fresh new solutions for an exciting and rapidly changing field.

What You Will Do

• Own and operate multi-account AWS and GCP environments (access, reliability, cost, and security posture)
• Lead capacity planning, patching, and cost optimization proactively
• Manage infrastructure using Infrastructure as Code (Terraform, Ansible, or equivalent)
• Identify and remediate security risks, misconfigurations, and reliability gaps

Observability and Reliability (Datadog)

• Own and evolve the Datadog observability stack across all environments
• Ensure strong coverage across logs, metrics, and alerting for production systems
• Continuously improve signal-to-noise ratio in alerting
• Build and maintain a unified operational dashboard with real-time system visibility
• Drive measurable improvements in MTTD and MTTR within the first 6 months

Incident Response and Operational Excellence

• Lead incident response, root cause analysis, and post-mortems
• Improve system resilience by addressing root causes and preventing recurrence
• Identify and close monitoring and operational gaps before they surface as incidents

Documentation and Enablement

• Maintain production-grade documentation for critical systems, including architecture diagrams, SOPs, and incident runbooks
• Ensure documentation enables independent execution by other engineers
• Keep documentation aligned with system reality as environments evolve

Proactive Improvement (Core Expectation)

Deliver consistent, measurable improvements across automation and toil reduction, observability coverage and quality, security posture and compliance readiness, and operational processes and tooling. Approach problems with a systems mindset: fix root causes, not symptoms.
