AWS Cloud Engineer
ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.
We are seeking a AWS Cloud / DevOps / Platform Engineer who can operate with a high degree of ownership and independence while contributing to the design, build, and operation of scalable AWS environments.
This role is suited for early-career engineers who already have hands-on AWS experience and are ready to take on more responsibility in managing cloud infrastructure end-to-end. You will partner with DevOps, Security, and Application teams, while also being trusted to drive tasks independently—from implementation through troubleshooting and optimization.

Support and troubleshoot hybrid and multi-account AWS environments
Own configuration and resolution of VPN, Direct Connect, and routing issues
Collaborate with DevOps teams on CI/CD pipelines, while independently executing assigned automation tasks
Monitor cloud resources and proactively optimize for performance, cost, and availability
Lead initial troubleshooting for incidents and contribute to root cause analysis
Apply AWS security and networking best practices in day-to-day operations
Create and maintain clear technical documentation with minimal guidance
Required Skills & Experience
3–5 years of experience in cloud, infrastructure, or DevOps engineering
Hands-on experience with AWS services, especially:

Experience with Infrastructure as Code (Terraform, CloudFormation, or CDK)
Working knowledge of Linux systems
Proven ability to troubleshoot network connectivity and performance issues independently
Familiarity with multi-account AWS environments
Education
Degree in Computer Science, Engineering, Information Systems, or a related technical field from an accredited university or technical institute in LATAM (Argentina, Chile, México, or equivalent) preferred
Alternatively, completion of a recognized technical or vocational program (e.g., coding bootcamp, cloud engineering program) from a reputable LATAM institution, combined with relevant hands-on experience
AWS certifications (e.g., Cloud Practitioner, Solutions Architect Associate) or equivalent training strongly preferred
Demonstrated commitment to continuous learning through certifications, labs, or real-world projects
Soft Skills
Ability to work independently, prioritize tasks, and take ownership of deliverables
Strong problem-solving and analytical mindset
Clear communication of technical concepts in English
Proactive, self-driven, and collaborative approach
Growth mindset with a strong interest in cloud and networking domains
For US-based roles - What you’ll get:
