About The Position
We are looking for a Senior Platform Engineer to establish and grow ReflexAI’s Platform Engineering function. This is a high-impact, multidisciplinary role for someone who thrives in growing startups, enjoys wearing multiple hats, and is excited about working cross-team in a mission-driven organization. You will improve and maintain our multi-cloud infrastructure (GCP + AWS), expand our golden paths and guardrails, refine our observability and monitoring, and elevate our security and compliance posture with every commit. As the second member of a new team, your input to our technical vision, partnerships with other teams and engineers, and expertise and ability to deliver high quality software and systems will make you successful. This is a rare opportunity to join a fast-scaling AI company that believes in the value of platform engineering, getting your hands dirty building tools, infrastructure, and processes used daily by every engineer.

- Strong experience building and maintaining CI/CD pipelines, guard rails, and golden paths for modern application stacks.
- Proficiency in modern observability ecosystems (Datadog experience is a major plus).
- Solid understanding of cloud security, IAM, container security, and network architecture.
- Experience with and excitement about AI-driven development.
- U.S. citizenship is required. This role supports ReflexAI's U.S. Department of Veterans Affairs contract and requires access to systems for which citizenship is a condition of access.
