Summary
👤
Senior🎓
Top SchoolJonathan Harden is a Senior Site Reliability Engineer with 11 years’ experience building and operating resilient, cloud-native systems and leading teams to do the same. He combines deep hands-on skills across AWS, containers, databases (Postgres, Cassandra, Aurora) and observability with a track record of zero-downtime migrations and cost-saving platform consolidations. As a mentor and technical lead he turns traditional dev and ops roles into effective SRE teams, documenting runbooks and wargaming risky changes to reduce incidents and alert fatigue. He has co-founded a serverless medical API startup, worked in large enterprise roles (Vodafone, GDS) and earlier cut his teeth optimising infrastructure for VFX at MPC on films such as Life of Pi. Known for pragmatic, incremental delivery, he also passed Mensa’s entrance exam—an underscored detail that reflects his analytical approach to complex systems.
