Position Summary

We are hiring for a highly experienced Senior Staff SRE Engineer to act as a senior technical authority within our reliability function. This is a deeply hands‑on individual contributor role, to build and operate SRE practices at scale. You will design and evolve resilient infrastructure, drive reliability across multiple engineering streams, and ensure our AI‑driven products operate with high availability, performance, and security. You will work across platform, product, data, and ML teams, helping us productionise models, absorb and standardise customer environments, strengthen Kubernetes‑based architecture, and mature our CI/CD pipelines end‑to‑end. You will also collaborate with other Staff engineers and Architects to shape the global product architect and technology vision.

• Build and enforce strong Infrastructure‑as‑Code standards.
• Define and operationalise SLIs, SLOs, and error budgets.
• Strengthen observability across applications, infrastructure, data pipelines, and ML systems.
• Work closely with product and data teams to integrate model analytics and product telemetry into reliability insights.
• Work across and optimise the entire CI/CD pipeline, from build to deploy to rollback.
• Improve release safety, deployment frequency, and predictability of SLAs.
• Lead incident response for complex cross‑system failures and drive postmortems.
• Reduce operational toil through automation and platform engineering improvements.
• Design processes and tooling to absorb, standardise, and troubleshoot customer environments.
• Support and productionise ML workloads (MLOps practices including model deployment, monitoring, retraining workflows).
• Ensure infrastructure aligns with enterprise‑grade security and regulatory requirements.
• Mentor engineers and raise the overall reliability bar across teams.

• Strong experience with observability tooling across distributed systems.
• Experience troubleshooting complex multi‑tenant or customer‑hosted environments.
• Experience supporting production data platforms and ML systems.
• MLOps experience, including model deployment and monitoring.
• Strong understanding of distributed systems, scalability, and fault tolerance.
• Systems thinker who understands interactions across infrastructure, product, data, and ML.
• Excellent communication skills and ability to work cross‑functionally.

Preferred Experience

• Experience in large‑scale global B2B/B2C products.
• Experience working with AI/ML systems, NLP, or LLM‑based products.
• Experience integrating product analytics and model performance metrics into operational monitoring.
• Background in enterprise environments with strong security and compliance requirements.
