  • Accountable for results and best in class outcomes
  • Visionary in future focused problem-solving

The Role

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.

Responsibilities

  • 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

What You Bring to the Team

  • 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)

Why Proofpoint?

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
