Required Al Infrastructure & Reliability Engineer
What this role is really about
Youll join a 3-person platform team within our Business Technology group -owning the internal infrastructure that our AI platform and its users depend on. This isnt a product engineering role, and it isnt ticket work or babysitting pipelines someone else built. Youre building and operating the internal foundation that the company runs on. The work covers the full stack of platform engineering: core cloud infrastructure (AWS, Kubernetes, IaC), CI/CD pipelines, AI-driven infrastructure components, and the SRE and observability practice that keeps it all honest -metrics, alerting, incident response, and reliability standards. As our AI capabilities grow, so does the complexity underneath them, and staying ahead of that is central to the role. If you treat infrastructure as a product -reusable, automated, observable, and built to last -this is your kind of role.
Job responsibilities
DevOps & AI-Driven Infrastructure - own CI/CD, deployment processes, and release reliability. Build and operate cloud infrastructure that is automated, intelligent, and continuously self-improving - not just managed.
Design and build our Terraform repository and IaC pipeline from scratch -AI-assisted generation, drift detection, and policy enforcement built in.
Build AI-driven GitHub Actions pipelines -automated code review, risk assessment, and intelligent deployment decisions.
Manage Kubernetes workloads across AWS accounts -zero downtime, fully automated, nothing left behind.
Embed AI into the operational layer -proactive drift detection, automated remediation, and intelligent scaling toward a self-healing runtime.
Reliability & SRE -improve uptime, resilience, and incident response.
Define and enforce SLOs/SLIs, error budgets, and on-call practices.
Lead incident response, postmortems, and systemic reliability improvements.
Own AI-specific reliability: model latency SLOs, token quota monitoring, rate limit handling, fallback and retry strategies, and cost-per-request alerting.
Observability & Telemetry - increase visibility, reduce noise, improve troubleshooting.
Establish and continuously evolve the observability stack: metrics, logs, distributed tracing, and alerting tuned for both application and AI workloads.
AI / LLM Operations- bringing AI systems to production and operating them at scale, with a focus on reliability, performance, and trust.
Own the AI infrastructure layer: rate limits, quota management, latency SLOs, and fallback strategies (retries, circuit breakers).
Operate LLM APIs in production with resilience and cost attribution per team/model.

The MLIL FLOW team is looking for a Senior Software Development Engineer to lead the design and delivery of systems software for our next-generation ML accelerator servers.

We work on the physical systems that execute ML workloads: Server bring-up, hardware diagnostics, interconnect validation, power/thermal monitoring, and fleet-scale operations are our bread and butter.


Key job responsibilities
Lead the architecture and implementation of hardware validation and diagnostic software for new ML acceleration platforms.
Drive technical direction for PCIe validation, power/thermal diagnostics, and stress-testing frameworks that run across manufacturing, vetting, and production environments.
Own subsystems end-to-end: from design through implementation, testing, deployment, and operational excellence at fleet scale.
Work with Hardware, Manufacturing, EC2 teams to create coordinated software packages that enable both qualification and rapid deployment.
Debug and root-cause complex hardware/software interaction failures on first silicon and production fleet returns; drive root-cause to closure.
Build and maintain data pipelines, dashboards, and monitoring systems for fleet health and performance benchmarking.
Mentor engineers, define best practices, drive design reviews, and raise the bar for the team.
Lead multiple development initiatives in parallel, balancing schedule, risk, and technical quality across a fast-moving hardware program.
