Desirable

• As a Senior Software Engineer on the Framework team, you will take ownership of complex development challenges, lead technical design within your area, and play a meaningful role in shaping how we build and scale the systems that power ExtraHop's core products
• You will work closely with cross-functional partners in Engineering, Product, and Security to deliver customer-facing features that enable detection, visibility, and automation at scale
• This role is ideal for an engineer who brings technical depth, exercises sound judgment independently, and is motivated to grow their impact through excellent engineering and active collaboration
• Our team builds high-performance network detection and monitoring systems that operate at scale across increasingly complex protocols and data volumes.Our services and features are written primarily in C and C++ with a focus on security, scalability, stability, and reliability
• Our team is focussed on enhancing, maintaining and optimizing core components of the system and functional areas related to protocol parsing, metrics publishing, continuous packet capture and Time Series DB
• This role focuses on designing and optimizing these core systems with an emphasis on performance, reliability and deep protocol awareness
• You will work on next generation initiatives including scaling and performance improvement efforts, evolution of our data storage architecture (custom to open-source based) and early steps towards a cloud enabled model
• Design, develop, and maintain high-performance services for ExtraHop's core Framework systems, taking ownership of moderately complex to complex features with limited guidance
• Work across networking layers to implement and enhance protocol support
• Participate actively in technical design discussions, contribute to architecture decisions within your team, and author clear technical documentation for your work
• Engage fully in agile development processes, including sprint planning, code reviews, and retrospectives; hold a high bar for code quality and test coverage
• Collaborate with Product and cross-functional engineering partners such as platform , infrastructure and cloud teams to translate business requirements into well-scoped, scalable engineering solutions
• Investigate, diagnose, and resolve production and performance issues independently; conduct root-cause analysis and implement preventive measures
• Contribute to platform modernization efforts and help evaluate and adopt new technologies or frameworks in partnership with senior and principal engineers
• Participate in on-call rotations and improve system observability, reliability and operational readiness
• Mentor junior engineers through code pairing, reviews, and knowledge-sharing; actively contribute to a strong team learning culture
