About The Position

MS2 is seeking a Senior Platform Engineer (SaaS Operations) to improve the reliability, security, operability, and continuous improvement of our SaaS platform. This hands-on senior engineering role designs and automates the infrastructure, delivery systems, and operational practices that enable reliable service delivery, safe software releases, and efficient engineering workflows. The role combines AWS infrastructure ownership, production operations, incident response, observability, security controls, server lifecycle management, and platform enablement to improve stability, scalability, and supportability. You will partner closely with Engineering, QA, Technical Support, and Product to reduce operational risk, strengthen deployment and recovery practices, and improve service reliability across the platform. When platform capabilities intersect with customer-facing workflows, you will also troubleshoot and make targeted contributions to backend services and integrations. The ideal candidate takes ownership of production platform health, leads the resolution of complex cross-layer issues, reduces recurring operational work through automation, and drives measurable improvements in reliability, performance, recovery readiness, and engineering efficiency.
