Software Engineer III

The Role 

Proofpoint is looking for a Software Engineer II to join our Unified Detection team, working on building and deploying large-scale threat detection services. Our team employs cutting-edge technology to detect, analyze, and produce intelligence on the latest threats from sophisticated cyber threat actors. Our detection services are foundational components leveraged across Proofpoint's cybersecurity product offerings to protect customers from threats delivered through email, social media, and SaaS applications. 
 
We are looking for an engineer who is developing their professional expertise, writes clean and well-tested code, and is eager to grow within a strong engineering culture. You understand the broader technical ecosystem, take ownership of smaller features and components, and collaborate effectively with your teammates to deliver high-quality work. 
 
We are a fast-paced, high-energy team where you will have the opportunity to learn quickly, contribute meaningfully, and grow your skills alongside experienced engineers. 

What you'll do 

• Contribute to moderately complex features and components, ensuring your work integrates seamlessly into the larger detection system. 

• Write clean, maintainable, and efficient code — leave the codebase better than you found it. 

• Begin taking ownership of smaller features or components, ensuring quality through thorough testing. 

• Work with minimal supervision on routine tasks, and proactively seek guidance when facing unfamiliar challenges. 

• Anticipate potential blockers, communicate risks early, and collaborate with the team to address them within established timelines. 

• Collaborate well with teammates — listen actively, incorporate feedback, and contribute constructively to reviews and discussions. 

• Actively participate in code reviews and retrospectives, providing constructive input and implementing feedback with a growth mindset. 

What we're looking for

• Bachelor's degree in Computer Science or Information Systems (or equivalent practical experience). 

• 2+ years of experience developing software, with growing proficiency in Python, Go, or Java. 

• Experience with observability or monitoring tools (Grafana, Kibana, or similar), preferred

• Developing understanding of distributed systems, cloud environments (AWS or similar), and containerized workloads (Kubernetes, Docker). 

• Familiarity with RESTful APIs, secure coding foundations, and automated testing practices. 

• Curiosity about cybersecurity, malware analysis, or threat detection is a bonus.
