We're looking for a Sr. Software Engineer to join our team and help build, scale, and maintain the systems powering our platform. You'll work across a large, complex micro-services architecture. This role is for someone who enjoys digging into hard problems, isn't afraid of ambiguity, and wants to keep pushing their own skills forward.

• Design, build, and maintain services across our micro-service ecosystem
• Debug complex, cross-service issues — you'll need to dig deep, trace root causes, and see problems through to resolution
• Participate in an on-call rotation, responding to and resolving production issues
• Collaborate closely with teammates, clearly communicating technical trade-offs, decisions, and progress
• Navigate ambiguous problems and evolving requirements, helping bring clarity and direction to the team
• Use AI-First and AI-assisted development tools where practical to improve velocity and quality
• Take on unglamorous but necessary work when the team needs it — tech debt, infra-migrations
• Continuously look for ways to innovate and improve how the team builds and operates software

• Proven software engineering experience with a level of seniority
• Proficiency in Java, Go, and Python
• Strong debugging and problem-solving skills — comfortable tracing issues through complex, distributed systems
• Experience with (or strong aptitude for) large-scale microservice architectures
• Comfortable with on-call responsibilities
• Openness to AI-first development practices and tools
• Excellent communication skills and a collaborative, team-first mindset
• Comfortable operating in ambiguous situations without needing every requirement fully spelled out
• A self-starter mentality — willing to challenge yourself, take initiative, and step up wherever the team needs help, including on less glamorous work
• BSc Degree in Computer Science or a related field (or equivalent practical experience)

At Proofpoint, we believe that an exceptional career experience includes a comprehensive compensation and benefits package.

• Competitive compensation
• Comprehensive benefits
• Career success on your terms
• Flexible work environment
• Annual wellness and community outreach days
• Always on recognition for your contributions
