Role

We are looking for a Staff Software Development Engineer to join our Engineering department. This is a hybrid role based in Bangalore, reporting to the Sr. Director, Software Engineering.

You will be responsible for writing the frameworks and tools used to test our products, occupying a unique space that combines the "building" mindset of software design with the "breaking" mindset of software test engineering. In this role, you will design and develop wide-reaching tools and write code that automatically verifies product quality, often writing more code than the developers themselves.

What you’ll do (Role Expectations)

• Build robust frameworks and tools specifically designed to test complex products
• Design and develop wide-reaching tools that impact the entire engineering lifecycle
• Write high-quality code to automatically verify product quality and ensure seamless performance

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You are a problem-solver. You seek out challenges because you are energized by finding solutions, knowing that solving the hard problems delivers the biggest impact.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You are a learner. You have a true growth mindset and never stop developing yourself, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.
• You operate with urgency. You understand that in a high-growth environment, speed and quality are not mutually exclusive. You have a relentless focus on execution and a bias for action, delivering high-impact results quickly to win for the customer and the team.

What We’re Looking for (Minimum Qualifications)

• Demonstrated curiosity and active exploration of AI tools, with a proven history of integrating new technologies to enhance daily workflows and augment problem-solving
• 5+ years of experience working on systems or distributed systems with a focus on networking, firewall technologies, and cloud infrastructure
• Hands-on proficiency in Python or Golang
• Foundational knowledge of public cloud computing platforms such as AWS, GCP, or Azure
• Experience with virtual environments including Docker, containers, Kubernetes, and OVA
• Proven track record of building automated testing frameworks

What Will Make You Stand Out (Preferred Qualifications)

• Deep understanding of TCP/IP protocol stack, HTTP, TLS, PKI, and related networking products like DNS, DHCP, VPN, and HA
• Familiarity with security technologies such as firewalls, IPS, and Authentication
• Advanced expertise in software development lifecycles and high-level development automation
