Who we're looking for

We're looking for a senior platform engineer who thrives on solving problems that don't yet have a playbook. You'll work directly alongside Supio's core engineering team building our agentic product, helping shape how we develop, deploy, and observe AI agents in production - an area where the industry hasn't settled on standards yet. You're energized by ambiguity, comfortable moving between deep infrastructure work and close day-to-day collaboration with product engineers, and motivated by ownership rather than tickets. This is a hands-on, builder-oriented role for someone who wants to be embedded with the team shipping Supio's flagship agentic experience.

What you'll do

• Own Agent Reliability & Observability: Evolve our observability stack - metrics, logging, tracing, alerting - that keeps Supio's agentic platform reliable in production.Drive Agent CI/CD: Design and maintain the CI and release pipelines that let the core engineering team ship new agent capabilities quickly and safely, in a space where testing and deployment standards for AI agents are still being invented.
• Partner with Product Engineering: Work directly and daily alongside the core engineering team, embedding platform expertise into how they build.
• Strengthen Core Infrastructure: Support and improve the underlying infrastructure - AWS, Kubernetes, databases, networking - that the agentic platform runs on.
• Productize Self-Serve Tooling: Turn ad hoc infrastructure needs into self-serve tools the product team can use independently, reducing their dependency on direct infra support.

Qualifications

• Experience: 5+ years in platform engineering, SRE, or infrastructure engineering, with direct ownership of production systems.
• Education: Bachelor's degree in Computer Science or related field, or equivalent practical experience.
• Technical Skills: Production experience with AWS, Kubernetes, and infrastructure-as-code (Terraform); hands-on with CI/CD pipelines (GitHub Actions); working knowledge of databases (Postgres) and messaging/queuing systems ; strong networking fundamentals.
• Observability: Demonstrated experience building or integrating observability tooling (metrics, logging, tracing, alerting), including making build-vs-adopt decisions and driving self-serve adoption.
• AI/Agentic Platform Experience: Hands-on experience building, operating, or supporting an AI/LLM or agentic platform in production.
• Cross-functional Collaboration: Track record of working directly alongside product/application engineering teams.
• Automation & Scripting: Comfortable writing scripts or light code to automate infrastructure tasks, with a solid understanding of software architecture fundamentals.
• Judgment Under Ambiguity: Able to operate effectively without an established playbook and exercise sound technical judgment in a fast-changing environment.

Nice-to-haves

• Background in distributed systems, data pipelines, or data analysis
• Startup or early-stage company experience with a builder mindset
• Experience productizing internal tooling for self-serve use by other engineering teams
