Tessian jobs

Proofpoint is hiring a Sustaining Engineer for their Archive Platform, a large-scale distributed system spanning legacy data center and AWS cloud infrastructure. This is a deep technical role focused on production engineering rather than traditional support—you'll lead root cause analysis investigations, implement code-level and architectural fixes, and drive systemic reliability improvements across mission-critical services. You'll need 5+ years building and operating commercial software systems, strong proficiency in C#, Java, or C++, deep knowledge of distributed systems and high-availability architectures, and full-stack capability across backend services, databases, and infrastructure. The role includes 24/7 on-call rotation responsibilities. Proofpoint is a global cybersecurity leader protecting over 80 of the Fortune 100; this position is based in India and has been open for 30+ days. The standout detail is that this is explicitly positioned as an engineering owner role requiring direct code contributions and live system debugging rather than a support track position.
