About the Role

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 posture with every commit. As the second member of a new team, your input to our technical vision, partnerships with other teams, 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.

What You’ll Do

• Design, automate, and reduce the toil associated with maintaining ReflexAI’s multi-cloud infrastructure across Google Cloud and AWS.

• Drive observability, reliability, and cost efficiency.

• Create safe, reliable, scalable, and secure paths for software and systems to reach production.

• Own the tooling that engineers use to build, test, and deploy code.

• Standardize pipelines, guard rails, and gold paths to accelerate developer velocity.

• Introduce and improve internal tooling that reduces operational overhead.

• Improve on-call ergonomics and reduce MTTR through better instrumentation.

• Implement best practices for secrets management, IAM, network security, vulnerability scanning, and container security.

• Build automated checks and secure-by-default workflows into CI/CD and cloud environments.

• Collaborate with Compliance and Security teams to ensure ReflexAI meets industry and customer expectations.

What We’re Looking For

• 5–7+ years of experience in DevOps, SRE, infrastructure, and platform engineering roles.

• Deep hands-on expertise with cloud platforms (GCP and AWS) as well as Terraform and Terragrunt.

• 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 AI-driven development.

Nice to haves

• Experience working in a fast-growing startup environment.

• Backend-related coding experience, primarily with Typescript

• Background supporting machine learning, model serving, or data-intensive workloads.

• Exposure to compliance frameworks (SOC 2, HIPAA, GDPR, ISO 27001, HITRUST).

• Prior experience building internal developer platforms or paved-path tooling.

What we offer

• Some of the most rewarding work you will ever do, solving real problems and helping people be the best versions of themselves

• Working alongside a team that is exceptionally smart and ambitious, but also humble and kind

• Flexibility to work remotely from anywhere in the United States

• Generous retirement, equity, healthcare, and PTO policies
