Principal Software Engineer - Core Security

Join us as we pursue our disruptive new vision to make machine data accessible, usable and valuable to everyone. We are a company filled with people who are passionate about our product and seek to deliver the best experience for our customers. At Splunk, we’re committed to our work, customers, having fun and most meaningfully to each other’s success.

Splunk is looking for a Principal Security Software Engineer to work on significant problems in securing the core Splunk engine. We build software that lets you search, report, monitor and analyze live-streaming and historical data across the entire IT infrastructure, from one place and in real time.

You will work within our core development teams to build complex backend security services and ensure we deliver high quality secure code from day one. Ideally, you have an extensive development background (C++ required) and have the interest to progress to be a security engineer.

Your ability to keep up to date on all new development and security challenges and work with our teams to develop protection mechanisms is critical. Ability to dive deep and not just focus on high level architecture overview is required.

You will have a unique opportunity to have major impact on critical and revenue-generating security projects.


  • You'll develop authentication, authorization, and data security features in a large distributed system
  • You'll collaborate closely with PM and other engineers to understand customer needs and translate them into product features.
  • You'll participate in development of project timelines, implementation design specifications, system flow diagrams, documentation, testing and ongoing support of systems.
  • You'll guide and mentor other software engineers specially focusing on software design and architecture
  • You'll maintain and improve existing code with a pride of ownership.
  • You'll lead large projects and be self-driven


  • 8+ years total development experience
  • Extensive software engineering experience in C++ (Python is a plus)
  • Experience in advanced development, especially in distributed systems and large, complex system environments deployed at scale


  • Experience in building authentication, authorization, and data security end-to-end products or features
  • Some experience working with security technologies (SSL/TLS/X.509/SAML/OAuth/JWT/KMIP/PKCS#11/, etc..)
  • Some experience with low level cryptographic mechanisms like (AES/GCM/PBKDF2/HMAC/SHA2/ etc..)


BS, MS or PhD in Computer Science or related engineering discipline, with security emphasis highly preferred.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status


Thank you for your interest in Splunk!
